You know your shit. This is the more quick and concise video about overclocking I've ever seen. Probably took a lot of effort. Thank you for creating it.
Hello your channel is amazing , I have the dark hero and the 5900X is a 2 years old post but what about the setting in the Extreme Tweak Tab like Level Calibration, etc
This is a very well made video, and you have a firm grasp on all the different options for maximizing Zen 3 CPU's. I asked a question on one of your other videos about the chipset temps with this board a few weeks ago. I found the answer at a later point. In the 40-60C range depending on load, so temps are fine and the big chunk of heatsink they used works well. I was able to pick up one of these boards in the last week. In a few weeks I have a 5900X coming, and I'll refer back to this video when the right time comes. I tested a 3700X a few weeks ago with an older Crosshair Hero board.. (new to Ryzen after years with Intel). I recorded tons of data in many different situations, and you really do have a firm grasp on all the different variables and trade offs with these chips. They can be used many different ways depending on your use case. I'm looking forward to the new possibilities that this board and CPU will have to offer, and this video is a great guide for that. It really covers everything.
Fantastic guide! Coming from Intel systems, I was beginning to feel overwhelmed by relearning all of these settings for a different vendor - your video is very clear and makes it all seem easier than I had feared. I dropped you a like and a sub -- great to see a content creator working so hard to engage the community in the comments.
Awesome, thanks for the feedback. I presume you mean 1.40V and not 1.49V? - Yes, generally speaking, because I'm using custom loop water cooling I have more headroom for additional voltage than for example AIO or air cooling. If you're using other cooling types, the overclocking process is still the same BUT you will just have to lower the voltage (and thus will have to lower the frequency)
Thank you very much for this amazing video! I have the Dark Hero on the way along with some Gskill Royal Elite ddr3600 14-14-14-34. Right now I have a 5900xt in a Gigabyte Aorus Master and it runs stable all core 4.55 for sure with only 1.215 voltage. That is also with my current ram's xmp enabled (Royal ddr3600 16-16-16-36). Oh almost forgot this is 4x16 sticks and only cooling it currently with an Nzxt x73. Hoping to get a better oc with the new board. At the same time I'm also swapping in a Corsair rm1000x to replace a rm850x and a Z73. Just replaced a 2080ti with a 6900xt and even just that change has been amazing for my frames. Hoping to be able to hit ddr4000 with the new setup, and at least 4.6 all core with using Dynamic OC switching.
Great news for everyone: I'm testing the CTR 2.0 RC2 right now, which is the "Clock Tuner for Ryzen" by 1usmus. It has a feature called "Hybrid OC". It's literally the same thing as the "Dynamic OC Switcher". It allows for your "All Core OC" profile to be loaded only when your CPU usage exceeds a certain amount. You can configure this amount manually. With this, I was able to have an all core OC on my 5900x of 4700/4500 (CCX based), 1.275V. My multicore score increased by 10%. My single core score stayed the same. Amazing! Right now, it's still only available in early access for patreon subs, but the official RC3 release will come out to public towards the end of january, with PBO support! Edit: The newer versions coming towards end of Q1 2021 will feature automatic Curve Optimizer functionality! Really looking forward for that!
GREAT guide....You deserve more subs, so I subbed! Thank you! Edit: I have a 5950x ....and an RTX 3090....not going to keep it OC'd, but trying to hit the max 3D Mark I can get...I think I've hit the limit on the Vid card....need to tweak the CPU now....this makes it much easier to try this.
Dynamic OC Switching is a cool feature, but unfortunately it is limited to dark hero, because it requires PCB changes. Btw, you didn't push RAM high enough, leaving a lot of performance on the table. 3200 cl14 b-die should go to 3766 cl14 easily at 1.5v. 16gb is not the best too, the 32gb dual rank kit would be much better.
Any idea if ASUS intend to backport DOS-OC to other high-end X570 boards? Really big feature to implement but would be terrible if limited to just one product
There seems to be some misconception in how easy it would be to backport DOS OC. Two things: 1) The specific implementation like on Dark Hero requires a PCB level decision. As in: there must be a specific physical PCB trace present. So this very much eliminates the possibility of bringing it to past products. 2) I don't know enough about software but I guess there might be a way to 'mimic' the behavior of DOS OC. After all, DOS OC is just changing the frequency and voltage at a specific trigger point. I would always prefer a hardware-level solution though :)
www.overclock.net/threads/asus-crosshair-viii-dark-hero-board-when-will-it-be-available.1774450/post-28666449 From the person who designed and implemented the feature at ASUS. I don't see it coming to any other older, ASUS boards and other brands would have to design and implement the feature themselves. "For other boards, the only way I can think of making this to 'possibly' work there may be considered unorthordox, and im not even sure if that's possible."
I just bought a 5900x and an Asus motherboard. This video really does help because I'm finding issues with thermal and voltage with the stock settings. The core voltage will jump up to 1.47 volts at 4.9 gigahertz. That's great but the system runs up to 70° c on an AIO. I don't believe this is realistic to get some minor performance to upvote my CPU automatically stock. I'm really having a hard time finding realistic guides that shows you some good points and bad points with manual OC. Even tweaking the stock OC would help as well
Hi Gerry, 1.47V at 4.9 GHz is expected behavior for a Ryzen 5000 CPU. You can check my video on PBO to get a clearer picture on how frequency and voltage relate (as well as how it actually doesn't run high voltage that often) ruclips.net/video/1wcU8PrdGLE/видео.html 70C is a perfect temperature. The Ryzen 5900X max temperature is 90C. The easy performance gains on Ryzen 5000 can be obtained by 3 things: XMP, PBO, Fmax Offset. It shouldn't take more than 30 minutes to enable all these and enjoy some additional performance.
@@SkatterBencher My ASUS Crosshair VIII Hero board does not have the ASUS Dynamic OC Switching option, but i was able to over clock it and got great results. Thank you again.
Great video. I am an AMD noob. I used PBO and set undervolt to 18 on all cores. My all-core clock peaks around 4400-4450mhz under avx load (Handbrake). My power threshold peaks around 142w but temps dont break 60c. Is this normal or should my all-core clocks go higher since my temps are still so low? I was hoping all-core PBO oc would hit closer to 4600mhz without going the manual oc route. Thanks again.
Hi which OC would you recommend for my build? I have a Ryzen 9 5900x, the x570 Dark Hero, Corsair Vengeance RGB Pro, 2 x 16 (32gb) 3200mhz, CL16, Lian Li O11-Dynamic XL ROG, and a Arctic Freezer ii 360 AIO. I have a fan setup of 6 fans from Lian Li (pwm fans). Should I just do a PBO and fmax offset? If so which do you recommend for the offset, or can I try Dynamic OC, or one of the other 2 OCs you mentioned in this video. Thanks again, such a good videos that is unbelievable clear and easy to follow. I just subscribed as well!
My computer kept crashing couldn't figure out what the problem was I lowered my 5900 to 4.5 gigahertz and I ran a 8700 points and went up a whole 500 points on cinebench r20 thanks for your help my man

Thanks for the kind words! I think the three scenarios I laid out in the video all have merit. - Go for PBO if you are looking for highest performance in light workloads like gaming (because PBO will boost beyond your all core maximum overclock). - Go for the Prime 95 with AVX stable setting if you're going to do occasional very heavy multi-threaded workloads and want to ensure stability in absolute worst case scenarios. - Go for the all-core maximum setting if you'll be running a mix of workloads (excluding the worst case) In the end, it will entirely depend on your system and your workloads. That's the beauty of overclocking - it is totally unique to your situation :)
Wow thanks for the reply. Sorry you were very clear in the video I guess I was just hoping for an idiot prof answer like my case was absolutely this setting no question. Subscribed and looking forward to more videos.
What is the best OC setting for gaming? My system: Ryzen 9 5900 x GPU: RX 6900 xt Sapphire Nitro ram: G.SKILL 32GB (2 x 16GB) Ripjaws V Series DDR4 PC4-25600 3200MHz Mobo: Rog Crosshair VIII Hero (WIFI) M.2 SAMSUNG 970 EVO Plus SSD 2TB Samsung 1TB 970 EVO NVMe M2 Solid State Drive
How to calculate that the estimated around value of 125 and 35 of "Current Threshold to Switch to OC Mode"? Is that my below understanding correct? 1.3V * 125A = Switch to manual OC when over 162.5W 1.4V * 35A = Switch to manual OC when over 49W I saw that the suggested value is 30A. Also, will this value be affected by load-line calibration? Thanks a lot.
From 13:12 I explain how to set up the current threshold value. It's not a value that can be calculated using a formula, but has to be estimated by hand.
Very interesting stuff! Am looking to OC for the first time ever with my new 5900x. I am on an ASUS board with 3600MHz RAM. Can you recommend a certain one of the described methods if I am looking for stability while achieving best possible gaming Performance to a newbie?
To a newbie I would suggest: 1) For daily running, probably just enable PBO + XMP. That should get you within 95% of your max possible performance. 2) Try manual OC to familiarize yourself with the process. It's always good to learn new things and, who knows, maybe you find out it's a new hobby :) Good luck!
@@SkatterBencher Thanks for the guides, I’m in a similar situation, I have Corsair vengeance C18 ram 4x8, when I set XMP (amd equivalent) and 3600mhz, the system wont boot got blue screen loop. Then I set the DRAM to 1.4, the system works fine and stable in games. However I run stability test aida64, I’m failing at cache stress test, single cpu or ram test is good. Do you think if I enable the PBO, it will fix the cache stress test failure issue?
+ sub fron Italy :). For me a quick explanation on the single option and value that you manager Will Be awesome. For example for Dynamic oc. Which is vcore limit to be safe Daily?
Great video, just started following you today. Have you tried using 4 dims of the same RAM, as opposed to the 2 you are using in this video? It seems that 4 dims should give a performance boost, but maybe it will not OC as well.
It's not 4 DIMMS that give the performance, it's the number of ranks, the extra performance comes from interleaving. For example, 16GBx2 dual rank memory will give you the same performance boost as 8GBx4 at single rank. GN's video was good but they completely omitted this, many of us were surprised.
@@scythe321 Well, I'm no pc wizard, but are you sure, as GN kept repeting the only difference for the higher scores was 2 or 4 dimms, not the size of the sticks.
@@BlindGoose1 My mistake, my example isn't very clear unless you know how RAM chips are physically configured. The size of the sticks can (for the most part) remain the same as it's irrelevant, what matters is whether they are dual rank or single rank. Quite often 16GB sticks are dual rank and 8GB sticks are single rank. Dual rank memory sticks can take advantage of a feature called interleaving which effectively emulates the performance effects of 4 physical sticks of RAM in the motherboard. There's some other easy digestible discussion here: www.reddit.com/r/hardware/comments/jq5rnw/amd_ryzen_4_vs_2_sticks_of_ram_on_r5_5600x_for_up/
There is something I don’t understand : it is how you set bios settings for DOS. It seems that you do twice the same settings for me....Am I wrong ? Is it a mistake or didn’t understand the way you set the DOS ? If I am not wrong, a video only for DOS on how to set the Bios settings in one time should be great 👍
In the video I give two examples of DOS configuration. The first example is with the Prime 95 stable settings (4.55G) and the second example is with the all-core max stable settings (4.75G). These are two different scenarios. I wanted to show that for these two cases you will have a different DOS OC configuration :)
Skaterbencher Great video! How come you use the Asus PBO menu and not the AMD subsection? I found the Asus area had limited PBO boost compared to AMD PBO2 section of the bios. On my Dark hero my 5900x boosts to 4.960MHz / 4.650 multi core. Ha Nebit been able to get the DOS playing nicely tho
Thanks for the kind words! I use the ASUS section because that's the section that's maintained by ASUS. If memory serves me right, the AMD section is provided directly by AMD in the BIOS code and is not checked/maintained by the motherboard engineers. I just prefer to use the section that's maintained by the motherboard engineers. Of course not all options from the AMD subsection are available, so if I need one of those I'll just do it in the AMD subsection. For example when using Fmax Offset in my 5600X video.
@@SkatterBencher Maybe it’s my board but I find using the Asus area seems to limit my clock. If I use curve opt under AMD I hit 4.6ghz all core. If I then turn on Asus fmax and PBO I front to 4Ghz all core. (5900x) It’s really confusing me!!
That sounds like strange behavior. The difference between PBO and PBO2 is pretty much the curve optimizer which is more designed for undervolting and increasing the frequency. So the standard frequency curve should be the same between PBO and PBO2. Do you reset all the BIOS settings when changing from PBO2 to PBO?
@@SkatterBencher yea always load ‘Optimised defaults’ after bios update. If I activate curve optimiser and set mobo limits in AMD, then go back to Asus area and enable. I drop all my clocks.
Hey man great video! I can actually say I learned some stuff. I have a EK custom loop as well. I’m running the asus x570-e with 64GB triden z neo 3600 c18 (2x32gb sticks) the ram is in the VQL. For some reason when I OC ram to 3600 at 1.4v everything crashes. I put it to 2333 1.35, still crashes. The cpu is stock, I haven’t touched anything. Can I use your settings and apply to my board? Will it work?
Thanks for the kind words! Regarding the memory, have you tried just enabling XMP? If that works, then start by setting the DRAM voltage equal to the XMP voltage (1.35V) and manually setting the DRAM ratio without manual timings.
Really appreciate your job, very very clear for me. I got my 5900x and x570 dark hero today. But my ram is old gskill Trident Z RGB F4_3200c16d CL16_18_18_38 1.35v (4x 8GB) How do I set DIMM voltage and DRAM timing control? Regards
How much does it take from the motherboard power delivery to do this reliably? What price bracket are we talking about rougly? I'm considering the MSI MAG X570 TOMAHAWK at 240eur since it's been said to have very good power delivery but is it enough for this kind of 5900x overclock? Or just shell out 100eur extra for a MSI MEG X570 UNIFY?
I saw peak power consumption of ~185W (158A 1.17V) when running Prime 95 SmallFFT with AVX at 4550 MHz ruclips.net/video/bXyyESN87iM/видео.html. Any VRM that can handle that will be able to handle the overclocking. I'm not a VRM expert, so best to check other channels for more information.
I tried the Prime 95 configuration and my 3D Mark Time Spy score dropped 800 points, XMP enabled, Z63 AIO, 3200MHZ CL16, at stock I hit 13,000+ on 3D Mark Time Spy.
This is expected behavior. By default, the AMD CPU has a very aggressive single thread frequency boost. So, if you do a conservative all-core overclock (like the Prime 95 config) your actual frequency in lightly threaded workloads will be works. This is a big drawback for AMD overclocking which is solved by DOS OC.
This one of the best OC videos for 5900x. I have a few question because I had some crash. I have a Mobo ROG CrossHero VIII (no black) with the latest fw First I tried with PBO and changing memory timings. When I try 16-16-16-16-36 I’ve got a crash, indeed it doesn’t boot. Maybe are my memories. I have 8x4 Adata Gammix D30 CL18 with high latency values of 17-18-18-20.. what you think? I should try a highest values? 16-17-17-19? Or buy new memories. Following your tutorial , leaving the memory timings, , it was very stable at 4.5 with very good values in cinebench 23 or CPU-Z. However when I try 4.7 it boot up and then in windows I’ve got a BSOD.. strange. One thing I try after is the Dual Intelligence Processor 5 from Asus just to know what numbers it reach. Surprisingly when start the CPU temp rise immediately near 100%. I think this sw is not optimized for 5000 series. I have a Noctua D15.. it kept very cool my old 3700x.. maybe that was my limit and the cause of the crashes besides my memory latencies. Do you suggest to try another thing? Thanks! Great video. I really want to try the dual switch..
Thanks for the kind words! Regarding the memory: what is the rated speed of your kit? If the timings from the video don't work, I would suggest to do the following: enable the XMP profile and set the DRAM ratio manually. This will set the memory frequency as you wish, and automatically configure the appropriate timings. Regarding the BSOD: it sounds like you are limited by cooling. In my video example, I use custom loop water cooling so there's a bit more headroom. I would suggest the following: go back to the stable 4.5 GHz setting and start reducing the CPU voltage 10mv. Every step, go back in the operating system to check system stability and the temperature. If the temperature drops a lot, then maybe there is more headroom to increase the frequency again. Best of luck!
@@SkatterBencher thanks for your advises. Yes, it seems that I don’t have to much headroom for cooling. I had to switch to full speed mode with my noctua DS 15 and the others Noctua on the cab ir order to manage 4.7 for a while. But at full speed is extremely noisy. Then I ran a performance test and it crashed again for overheating. I was found a sweet spot with my old 3700x with the DIP5 of Asus. It runs all cores to 4.2 with 1.2v and never get over 65c. Now with my new 5900x enabling only PBO with some light task like game download and installation I see it reaches almost 69C with an average clock of 4.4/4.5 (two cores only at the highest speed) so I’m little confused with this processor. I would try your suggestion of keeping 4.5 and lowering the voltage. Sounds good.. i don’t like to see the voltage so high.. thanks and again great video!
I’ve had another thought about this now that I’m actually working with a Dark Hero motherboard. Is it possible to use D.O.C.P. Defaults for RAM while using Dynamic Overclock Switching?I have a 3600 cl 14-15-15-35 kit trident neo kit
I have 5900X + Dark Hero motherboard. First time manually overclocking here, just got a question regarding DRAM Timing Control. I notice your settings are "16, 16, 16, 16 and 36"; what do I set for mine? My RAM 64GB (4x16) 3600Mhz CAS latency: 18-22-22-42, 1.35 V. Thanks.
I would suggest to not set the timings manually, but instead use XMP. On ASUS boards XMP is called DOCP. This will set your memory automatically at the frequency and timings it ships with. If it's not stable, then still enable XMP/DOCP and manually set the frequency lower than DDR4-3600. 64GB is pretty massive so it may be that the system isn't fully stable at DDR4-3600 especially with FCLK running in sync.
@@SkatterBencher It's cool ASRock is making some pretty nice boards these days.. They have a great support community, they've been putting out BIOSs' for 5000 series on their Gen one x370 boards the whole time, When the other companies wouldn't.. Maybe one of these days you'll get your hands on a nice Taichi board or a phatom gaming baord..
Enabling Precision Boost makes my computer turn off and power back on when I’m away from my desk. It ignores the Power Settings in Windows at idle. I have the Dark Hero X570
@@TheClearStalker Nope, all I do is set a Manual Thermal Limit of 75 degrees Celsius. Not sure about Precision Boost because you can enable Precision Boost under the CBS/NBIO/XFR settings, AMD Overclocking/Precisión Boost and the Xtreme Tweaker menu. I’ve tried it different ways but it just doesn’t work at all with my settings. Maybe it’s because I set a manual voltage for my CPU... either way not sure. When I first tried it, it worked like a charm. But afterwards not so much. Random restarts. AND there are better settings but you can’t pick all. Best PBO is with a Negative 30 Curve Optimizer with a 75 degree thermal limit and Disabled Limits in the Advanced Menu but you can’t use Dynamic OC. But be sure to set the Idle Control to Typical or it will shut off during Idle. A Negative 30 Curve is an under volt. I like undercoating otherwise Precision Boost will overheat your CPU. My Dynamic OC is actually 44.25 ratio at 1.2v and it actually cools down my CPU when PBO raises it.
I am completely new to amd system. Witch oc mode would you recommend for gaming? I saw a gaming mode in ryzen master but it only runs with 6 cores active :/ I want a nice stable oc for daily use and mostly gaming. Need some guidance lol.. Is all core or pbo best?
It genuinely depends on your system. I would suggest to do the following: 1) Run a 5 to 10 benchmarks with PBO enabled, write down the performance numbers (preferably choose a variety of tests) 2) Find the maximum all-core stable overclock with your system and cooling 3) Run the same benchmarks again with the all-core stable overclock 4) Compare the performance results What you'll likely see is that (a) in single-threaded and light workloads (i.e. certain games), PBO will give you higher performance; and (b) in multi-threaded and heavy workloads (i.e. rendering or excel formulas) the all-core OC will give you the highest performance. Then, make a choice :).
Dude sorry for the off topic question: I just order my dark hero. Does it need a bios update to fit a zen3 cpu or does it come updated? Thank you in advance.
I tried this and it didn’t work. I have 4000mhz ram and it didn’t boot. I tried when I had just bought my Dark Hero Motherboard. I’ve since gotten acquainted with it and I paid more attention and realized that they can only get their 5900X overclocked to 4.325ghz with AVX stress test and I have mine running at 4.425ghz at 1.2V overclock completely stable on ROG Realbench.
The memory timings from the video might be a bit too tight for most sticks. It was an oversight from me - shouldn't have tuned those :). You can always try just enabling XMP. That should help you tune the memory timings and Fclk frequency to enable DDR4-4000.
@@SkatterBencher I found out that by enabling PBO that it is unstable during idle. So the computer will shut off and reboot when I’m away from my desk. Only during idle. 45.50 ratio tops out at 85C and PBO tops out at 90C using my 420 eisbaer AIO. I almost reached 9thousand in Cinebench R20 by setting a negative -30 curve optimizer. But Curve Optimizer doesn’t work with dynamic OC. The computer also shuts down during idle so I set everything on Auto. I think that Enabling PBO the BIOS ignores the Power settings for windows and for idling. I had to leave PBO on Auto and enable Dynamic OC with a ratio of 44.25 at 1.2V for 70C temps with an R20 score of 8400. I was also able to reach a ratio of 1:1 but it’s only a 100-150 point increase in R20. With a 1:1 ratio it increases my SOC voltage and it increases my temps so I don’t have enough headroom to overclock. I think that your chart which says 4325mhz is more likely rather than 4550mhz. The CPU temps on the motherboard tell me 60C but the CPU Pkg is 70C so it’s difficult to configure fan curves when you place a thermal limit on PBO. I’ve played around with the settings a lot. I’ve learned a lot and this video helped me a lot too.
Somehow it didn't work well with this particular kit of memory. I used DOCP in other AMD/ASUS videos like the Ryzen 7 5700G: ruclips.net/video/4gDfMwOBnoE/видео.html. Generally, I recommend using it.
This is a GREAT question! Let me expand a bit on this topic because it seems there's a lot confusion about this. First of all, running higher voltages in itself is not a problem. In fact, by default CPUs are configured to run well in excess of 1.4V when aiming for the highest boost frequencies. You can check this yourself with Hwinfo. Secondly, increased voltages become a problem when running longer, sustained, heavy workloads. Not only will it cause higher CPU power consumption but it will also increase the CPU operating temperature. This may affect the CPU stability, health and lifespan. That's why you'll see the CPUs reduce the voltage automatically. For example, in the toughest of workloads like Prime 95 with AVX the CPU voltage may be 1.0V or lower. Third, what overclockers do is accept the risks associated with running out of vendor specification. So we accept that higher temperatures and higher power consumption may affect the stability, health and lifespan of the CPU. Fourth, of course overclockers don't just accept the risk and move on. They try to mitigate the impact of taking the risks. One of the most common risk mitigations is improving the cooling. When you improve the cooling, for the most part you just increase the power budget. So, where a CPU would overheat at 125W with your regular cooling, with the better cooling you could run 150W without overheating. This better cooling allows us to set a higher voltage, which in turn allows us to set a higher frequency and get more performance. In normal circumstances (read: unless you use extreme cooling), the highest voltage you can use safely will be limited by your cooling solution rather than the voltage itself being unsafe. The maximum useful voltage for overclocking will depend on your system, CPU, cooling and motherboard. Hope this helps!
@@SkatterBencher Another question is - does this Core VID / Core Voltage specified the maximum value of voltage, not the constant one? Cuz I can track that when there is no load the voltage drops even to 300mV or does it specify the allowed peak voltage?
I would sell my Crosshair VIII Hero and get the Dark Hero if it was actually the MSRP but it's about $400 more (Australian), Asus stuff is always way overpriced here when it first launches.
@@martinfodor2848 No chipset fan, and also this Dynamic OC feature is only available on the more recent board. Better VRM as well. Otherweise they are similar.
because of ryzen master i cant do this without bsod ryzen master made some permanent changes to the bios that cant be undone even if i change stuff in the bios ryzen master just changes it back i heard uninstalling doesnt even fix it lmfao
In an ideal world, the voltage supplied to the CPU cores would be stable. In the real world, there are always fluctuations up and down. LLC helps reduce the fluctuations. It can help with overclocking when the fluctuation of the voltage goes too low and the frequency is not stable at that voltage. Using LLC will help avoid the voltage going too low. So, especially in situations with high workload it can be the difference between stable and not stable. I didn't use it in the video because (1) the motherboard already has "auto-rules" configuring the LLC and (2) it's quite advanced already and my videos aims to help people get started.
Soo.. listen here.. I have a NZXT Kraken X73. 3600MHz CL16, PBO Enabled Cinebench R20 Score: 8190 and temps going to 85c and sometimes spiking a bit more.. what is wrong with my system?
Nothing to worry about still. I believe the max rated temperature for Ryzen 5000 is 95C. If your CPU would spike above that, the CPU will automatically downclock/downvolt to protect the CPU.
By using the highest dynamic oc switching over clock in the video, does this raise overall cpu voltage? Could this introduce degradation to the life of the CPU?
Using DOS doesn't per definition raise the voltage. It just allows you to switch between Precision Boost Overdrive and OC Mode. Precision Boost Overdrive generally does a good job maximizing the processor frequency in any type of workload. However, it's still more conservative than when manual overclocking. So generally you'll find that a manual overclock with fixed voltage and fixed frequency will achieve better results than letting PB manage. Especially if you have no issue pushing both the voltage and temperature to the maximum limit as PB won't do that. So, if you set a non-conservative manual overclock with DOS OC, then the voltage and temperature for all-core workloads will indeed by higher than with Precision Boost. For semiconductors high voltage + high temperature are usually a cause for CPU lifespan reduction, though it's all relative. If your CPU goes from 10Y operation to 8Y operation, does it really matter?
@@SkatterBencher Thank you for this. Just bought a 5900x and got the best cooling i could without going custom. Primarily going to be gaming and i'm considering just mimicing the settings you used in the maximum manual all core overclock with DOS OC. Wanted to gauge any negative sideaffects of doing so. Cheers!
@@SkatterBencher For gaming OC, does it really matter if prime95 is stable or not? Could the non stable OC lead to unexpected crashing in this context? Thank you again 🙏
It could be anything. I would diagnose as follows: 1) leave memory at default, set the other settings 1a) if boots up -> memory issue. Try XMP instead of manual configuration 1b) if not boot -> reduce CPU ratio by 1, repeat until boot
@@SkatterBencher Well I think changing the default value from 3.7 to 4.0 will help if I set an FCLK of 2000 for my 4000mhz ram. It’s basically why 3600mhz ram is the sweet spot for a 3.7 cpu clock. I actually found the XMP settings for 1.8 or 3600mhz for my 4000mhz ram kit in the MOD software and it’s pretty impressive. If it can process at a default 4000mhz and overclock to 4425mhz I get about the same results as when I am running a large heavy workload on PBO on Auto with the CPU throttling the frequency just before 95 degrees. Except with 4.0 and 4.425 it’s only a max 65 to 70 degrees for the same performance uplift. The only better is a Negative 30 using Curve Optimizer, that’s a Low3-5mV for Minus 90millivolts when under load, and Minus 150millivolts when your CPU is not doing anything. My computer reboots when it’s in idle since it doesn’t get enough power to the CPU to stay on. Negative 30 according to the AMD bald guy is the max he said, in a video. It’s also on Optimum Tech. I almost reached 9thousand in Cinebench R20, I got an 8954. I found out by Trial and Error that using my 4.0ghz default will boost to an Overclock of 4425mhz at 1.2Volts. In fact both frequencies can be reached with 1.2Volts but I have to disable the precision boost overdrive because I am trying to keep the Temperatures low, and PBO will stay on and it will not go to Dynamic OC since PBO raises the temps more than Dynamic OC. The only thing I don’t understand when setting a Custom P0 State of 4025mhz Frequency, I don’t know what to set the VID at? I just left it at 38 VID because that’s what it was before. I don’t think that is right but I don’t know. Thanks for you guidance by the way, I really like the Dark Hero motherboard!!! 👍
@@SkatterBencher thanks! I have an issue with idle temps however When using a fixed vcore, 4.6@1.2, temps are idle at 37 to 40 and gaming around 50c However when i use pbo / curve etc it's around 50 to 60 just on desktop... Any idea why?
I doubt it. My 5800X only reached 4775 MHz, so marginally higher than 5900X (video up tonight). I just got a 5600X and will try it out tonight. If it can do 4800 I'll be a happy man!
People swear by the chip but everywhere I turn I see whea Error, kernal power issues, crashes everywhere -- is this cpu stable? I want to buy but I'm afraid that I will have unsolvable issues
@@rubbersoul420 Okie dokie, last question did you do any PBO settings changes? There's a curve priority and "boost priority" and people are changing numbers getting which core boots the quickest and overclocking that one more than the others or can I just mobo settings and call it a day?
@@jonahjameson272 it’s been very stable for me, even more so now that there’s a new non-beta bios. I couldn’t say about oc’ing the chip though as I just have my ram overclocked. The only issue I had was a specific asus problem where one of their software apps totally messed with my system until I did a clean windows install.
You don't need to manually disable PBO as the system will automatically do it when you start manual overclocking. On AMD systems, PBO and OC are two different "modes". So when using the one, you won't be able to use the other. Except of course with Dynamic OC Switching.
@@SkatterBencher thanks so much! This video was incredibly helpful, especially with the dark hero motherboard. Definitely will keep an eye on this channel 😁
Dynamic OC Switching will be a Crosshair VIII Dark Hero exclusive feature. Reason is it requires a PCB level change and without it this feature can't be implemented
The general process of manual overclocking and precision boost overdrive will work. However, dynamic OC switching feature is only available on the Dark Hero motherboard.
@@SkatterBencher I have a problem with CAD software Fusion 360. It uses only 1 core and every 10 sec it change one of 12 cores of my Ryzen 5900x and use it to 100%. So to get best performance (overclock 1 core which is changing to another core in time) I have to do what please?
For AMD platforms, the only way to maximize the single core performance is by using Precision Boost Overdrive. You can use curve optimizer and other tools to maximize the frequency ruclips.net/video/jTkDqARDkGg/видео.html
The all core maximum overclock will differ on each system. I didn't see any immediate temperature concerns but then again I was running custom loop and on a test bench. I think the "worst case" scenario using Prime 95 with AVX is a good indication of what would be the lower bound overclock of my system. That's why I also include it in the video 👍. In any case, always monitor the temperatures when overclocking. Safety first!
You know your shit. This is the more quick and concise video about overclocking I've ever seen. Probably took a lot of effort. Thank you for creating it.
Great content, I will be enabling this next week when my case finally arrives to finish my build! Subscribed for any future content.
Thanks for the sub!
Hello your channel is amazing , I have the dark hero and the 5900X is a 2 years old post but what about the setting in the Extreme Tweak Tab like Level Calibration, etc
This is a very well made video, and you have a firm grasp on all the different options for maximizing Zen 3 CPU's. I asked a question on one of your other videos about the chipset temps with this board a few weeks ago. I found the answer at a later point. In the 40-60C range depending on load, so temps are fine and the big chunk of heatsink they used works well. I was able to pick up one of these boards in the last week. In a few weeks I have a 5900X coming, and I'll refer back to this video when the right time comes. I tested a 3700X a few weeks ago with an older Crosshair Hero board.. (new to Ryzen after years with Intel). I recorded tons of data in many different situations, and you really do have a firm grasp on all the different variables and trade offs with these chips. They can be used many different ways depending on your use case. I'm looking forward to the new possibilities that this board and CPU will have to offer, and this video is a great guide for that. It really covers everything.
Very well explained video. Congrats !
Thanks!
Fantastic guide! Coming from Intel systems, I was beginning to feel overwhelmed by relearning all of these settings for a different vendor - your video is very clear and makes it all seem easier than I had feared. I dropped you a like and a sub -- great to see a content creator working so hard to engage the community in the comments.
Thanks for the kind words! And enjoy your new CPU :)
Thé best video I have seen on Ryzen OC ! So clear !
But, this requires a custom loop to be able to set a Vcore to 1.49V.
Awesome, thanks for the feedback.
I presume you mean 1.40V and not 1.49V? - Yes, generally speaking, because I'm using custom loop water cooling I have more headroom for additional voltage than for example AIO or air cooling. If you're using other cooling types, the overclocking process is still the same BUT you will just have to lower the voltage (and thus will have to lower the frequency)
Thank you very much for this amazing video! I have the Dark Hero on the way along with some Gskill Royal Elite ddr3600 14-14-14-34. Right now I have a 5900xt in a Gigabyte Aorus Master and it runs stable all core 4.55 for sure with only 1.215 voltage. That is also with my current ram's xmp enabled (Royal ddr3600 16-16-16-36). Oh almost forgot this is 4x16 sticks and only cooling it currently with an Nzxt x73. Hoping to get a better oc with the new board. At the same time I'm also swapping in a Corsair rm1000x to replace a rm850x and a Z73. Just replaced a 2080ti with a 6900xt and even just that change has been amazing for my frames. Hoping to be able to hit ddr4000 with the new setup, and at least 4.6 all core with using Dynamic OC switching.
Great news for everyone:
I'm testing the CTR 2.0 RC2 right now, which is the "Clock Tuner for Ryzen" by 1usmus.
It has a feature called "Hybrid OC". It's literally the same thing as the "Dynamic OC Switcher". It allows for your "All Core OC" profile to be loaded only when your CPU usage exceeds a certain amount. You can configure this amount manually.
With this, I was able to have an all core OC on my 5900x of 4700/4500 (CCX based), 1.275V. My multicore score increased by 10%. My single core score stayed the same. Amazing!
Right now, it's still only available in early access for patreon subs, but the official RC3 release will come out to public towards the end of january, with PBO support!
Edit: The newer versions coming towards end of Q1 2021 will feature automatic Curve Optimizer functionality! Really looking forward for that!
GREAT guide....You deserve more subs, so I subbed!
Thank you!
Edit: I have a 5950x ....and an RTX 3090....not going to keep it OC'd, but trying to hit the max 3D Mark I can get...I think I've hit the limit on the Vid card....need to tweak the CPU now....this makes it much easier to try this.
Thanks for the kind words!
As per usual, my recommendation for AMD Ryzen 5000 series is: XMP + PBO + Fmax Offset :)
This is amazing content. subbed!
Awesome, thank you!
Dynamic OC Switching is a cool feature, but unfortunately it is limited to dark hero, because it requires PCB changes.
Btw, you didn't push RAM high enough, leaving a lot of performance on the table. 3200 cl14 b-die should go to 3766 cl14 easily at 1.5v. 16gb is not the best too, the 32gb dual rank kit would be much better.
Any idea if ASUS intend to backport DOS-OC to other high-end X570 boards? Really big feature to implement but would be terrible if limited to just one product
There seems to be some misconception in how easy it would be to backport DOS OC. Two things:
1) The specific implementation like on Dark Hero requires a PCB level decision. As in: there must be a specific physical PCB trace present. So this very much eliminates the possibility of bringing it to past products.
2) I don't know enough about software but I guess there might be a way to 'mimic' the behavior of DOS OC. After all, DOS OC is just changing the frequency and voltage at a specific trigger point.
I would always prefer a hardware-level solution though :)
I dont think so - rog.asus.com/forum/showthread.php?121517-Crosshair-hero-viii-dynamic-oc-switcher
www.overclock.net/threads/asus-crosshair-viii-dark-hero-board-when-will-it-be-available.1774450/post-28666449
From the person who designed and implemented the feature at ASUS. I don't see it coming to any other older, ASUS boards and other brands would have to design and implement the feature themselves.
"For other boards, the only way I can think of making this to 'possibly' work there may be considered unorthordox, and im not even sure if that's possible."
Can you make a Video about Gaming oc amd 5900x and 5950x ?
Great. Now I have to reset cmos or something. My computer won't post after restart.
I just bought a 5900x and an Asus motherboard. This video really does help because I'm finding issues with thermal and voltage with the stock settings. The core voltage will jump up to 1.47 volts at 4.9 gigahertz. That's great but the system runs up to 70° c on an AIO. I don't believe this is realistic to get some minor performance to upvote my CPU automatically stock. I'm really having a hard time finding realistic guides that shows you some good points and bad points with manual OC. Even tweaking the stock OC would help as well
Hi Gerry,
1.47V at 4.9 GHz is expected behavior for a Ryzen 5000 CPU. You can check my video on PBO to get a clearer picture on how frequency and voltage relate (as well as how it actually doesn't run high voltage that often) ruclips.net/video/1wcU8PrdGLE/видео.html
70C is a perfect temperature. The Ryzen 5900X max temperature is 90C.
The easy performance gains on Ryzen 5000 can be obtained by 3 things: XMP, PBO, Fmax Offset. It shouldn't take more than 30 minutes to enable all these and enjoy some additional performance.
Great Video, I cant wait to go home and try it with my 5950X. Going to be a good Friday :-)
Good luck and enjoy!
@@SkatterBencher My ASUS Crosshair VIII Hero board does not have the ASUS Dynamic OC Switching option, but i was able to over clock it and got great results. Thank you again.

Great video. I am an AMD noob. I used PBO and set undervolt to 18 on all cores. My all-core clock peaks around 4400-4450mhz under avx load (Handbrake). My power threshold peaks around 142w but temps dont break 60c. Is this normal or should my all-core clocks go higher since my temps are still so low? I was hoping all-core PBO oc would hit closer to 4600mhz without going the manual oc route. Thanks again.
Thank you for all this great info
Hi which OC would you recommend for my build? I have a Ryzen 9 5900x, the x570 Dark Hero, Corsair Vengeance RGB Pro, 2 x 16 (32gb) 3200mhz, CL16, Lian Li O11-Dynamic XL ROG, and a Arctic Freezer ii 360 AIO. I have a fan setup of 6 fans from Lian Li (pwm fans). Should I just do a PBO and fmax offset? If so which do you recommend for the offset, or can I try Dynamic OC, or one of the other 2 OCs you mentioned in this video.

Thanks for the kind words!
I think the three scenarios I laid out in the video all have merit.
- Go for PBO if you are looking for highest performance in light workloads like gaming (because PBO will boost beyond your all core maximum overclock).
- Go for the Prime 95 with AVX stable setting if you're going to do occasional very heavy multi-threaded workloads and want to ensure stability in absolute worst case scenarios.
- Go for the all-core maximum setting if you'll be running a mix of workloads (excluding the worst case)
In the end, it will entirely depend on your system and your workloads. That's the beauty of overclocking - it is totally unique to your situation :)
Wow thanks for the reply. Sorry you were very clear in the video I guess I was just hoping for an idiot prof answer like my case was absolutely this setting no question.
Subscribed and looking forward to more videos.
Thx for the video, so how was the temps on all core 4.75ghz?
My 5900x hits 4.6ghz all cores with just a minus 30 curve optimized. It hits 4.95ghz single core.
Great video!!! Thank you! So out of these OC modes which would you suggest to use for a gaming PC with the 5900x?
Thanks for the kind words!
For AMD my recommendation is to enable XMP, use PBO, and try Fmax Offset.
@@SkatterBencher Sweet! Thank you for the insight!! I'll give it go.
@@SkatterBencher What fmax offset do you recommend? and PBO just enabled or the stronger settings?
I want to know too..
I always go straight for +200 and it never really gives me any issues. But you can try step by step to see if you see any instabilities
What is the best OC setting for gaming?
My system:
Ryzen 9 5900 x
GPU: RX 6900 xt Sapphire Nitro
ram: G.SKILL 32GB (2 x 16GB) Ripjaws V Series DDR4 PC4-25600 3200MHz
Mobo: Rog Crosshair VIII Hero (WIFI)
M.2 SAMSUNG 970 EVO Plus SSD 2TB
Samsung 1TB 970 EVO NVMe M2 Solid State Drive
On AMD: when in doubt, enable PBO and XMP. That'll get you within 95% of the best possible performance for gaming in a matter of seconds :)
How to calculate that the estimated around value of 125 and 35 of "Current Threshold to Switch to OC Mode"?
Is that my below understanding correct?
1.3V * 125A = Switch to manual OC when over 162.5W
1.4V * 35A = Switch to manual OC when over 49W
I saw that the suggested value is 30A. Also, will this value be affected by load-line calibration? Thanks a lot.
From 13:12 I explain how to set up the current threshold value. It's not a value that can be calculated using a formula, but has to be estimated by hand.
Nice video, just wondering if you have done any test with rx 6xxx xt series GPU and if so you've had any trouble with SAM/resizable bar?
Sorry, I didn't do any testing like that.
Very interesting stuff! Am looking to OC for the first time ever with my new 5900x. I am on an ASUS board with 3600MHz RAM. Can you recommend a certain one of the described methods if I am looking for stability while achieving best possible gaming Performance to a newbie?
To a newbie I would suggest:
1) For daily running, probably just enable PBO + XMP. That should get you within 95% of your max possible performance.
2) Try manual OC to familiarize yourself with the process. It's always good to learn new things and, who knows, maybe you find out it's a new hobby :)
Good luck!
@@SkatterBencher Alright I will try. Thank you for the advice!

Great video, just started following you today.
Have you tried using 4 dims of the same RAM, as opposed to the 2 you are using in this video?
It seems that 4 dims should give a performance boost, but maybe it will not OC as well.
I have not tried 4 DIMM for a while but I will consider it for future videos. Thanks for the feedback!
It's not 4 DIMMS that give the performance, it's the number of ranks, the extra performance comes from interleaving.
For example, 16GBx2 dual rank memory will give you the same performance boost as 8GBx4 at single rank. GN's video was good but they completely omitted this, many of us were surprised.
@@scythe321 Well, I'm no pc wizard, but are you sure, as GN kept repeting the only difference for the higher scores was 2 or 4 dimms, not the size of the sticks.
@@BlindGoose1 My mistake, my example isn't very clear unless you know how RAM chips are physically configured. The size of the sticks can (for the most part) remain the same as it's irrelevant, what matters is whether they are dual rank or single rank. Quite often 16GB sticks are dual rank and 8GB sticks are single rank. Dual rank memory sticks can take advantage of a feature called interleaving which effectively emulates the performance effects of 4 physical sticks of RAM in the motherboard.

There is something I don’t understand : it is how you set bios settings for DOS. It seems that you do twice the same settings for me....Am I wrong ? Is it a mistake or didn’t understand the way you set the DOS ? If I am not wrong, a video only for DOS on how to set the Bios settings in one time should be great 👍
In the video I give two examples of DOS configuration. The first example is with the Prime 95 stable settings (4.55G) and the second example is with the all-core max stable settings (4.75G). These are two different scenarios. I wanted to show that for these two cases you will have a different DOS OC configuration :)
is it possible to make a video showing the best undervolt for the ryzen 5950 and still gain in performance for games and programs?
Interesting idea. What would be the use-case for this?
@@SkatterBencher decrease the temperature for example of the processor and try to gain a performance gain if possible.

Great video!
How come you use the Asus PBO menu and not the AMD subsection?
I found the Asus area had limited PBO boost compared to AMD PBO2 section of the bios.
On my Dark hero my 5900x boosts to 4.960MHz / 4.650 multi core. Ha Nebit been able to get the DOS playing nicely tho
Thanks for the kind words!
I use the ASUS section because that's the section that's maintained by ASUS. If memory serves me right, the AMD section is provided directly by AMD in the BIOS code and is not checked/maintained by the motherboard engineers. I just prefer to use the section that's maintained by the motherboard engineers.
Of course not all options from the AMD subsection are available, so if I need one of those I'll just do it in the AMD subsection. For example when using Fmax Offset in my 5600X video.
@@SkatterBencher Maybe it’s my board but I find using the Asus area seems to limit my clock.
If I use curve opt under AMD I hit 4.6ghz all core.
If I then turn on Asus fmax and PBO I front to 4Ghz all core.
(5900x)
It’s really confusing me!!
That sounds like strange behavior. The difference between PBO and PBO2 is pretty much the curve optimizer which is more designed for undervolting and increasing the frequency. So the standard frequency curve should be the same between PBO and PBO2.
Do you reset all the BIOS settings when changing from PBO2 to PBO?
@@SkatterBencher yea always load ‘Optimised defaults’ after bios update.
If I activate curve optimiser and set mobo limits in AMD, then go back to Asus area and enable. I drop all my clocks.
Hey man great video! I can actually say I learned some stuff.
I have a EK custom loop as well. I’m running the asus x570-e with 64GB triden z neo 3600 c18 (2x32gb sticks) the ram is in the VQL. For some reason when I OC ram to 3600 at 1.4v everything crashes. I put it to 2333 1.35, still crashes. The cpu is stock, I haven’t touched anything.
Can I use your settings and apply to my board? Will it work?

Regarding the memory, have you tried just enabling XMP? If that works, then start by setting the DRAM voltage equal to the XMP voltage (1.35V) and manually setting the DRAM ratio without manual timings.
@@SkatterBencher nope, even using xmp the pc and games crashes. I've tried 3 different sets of ram.

Any with this same mobo and cpu have any problems? I am seeing a good amount of people in general having WHEA errors and random reboots.
Depends if you are running a PCIE 4.0 GPU or not.. plus other factors. In time, these issues should smooth themselves out.
@@Jonw8222 I'm running 3070 in 4.0 and all good.
How much does it take from the motherboard power delivery to do this reliably? What price bracket are we talking about rougly? I'm considering the MSI MAG X570 TOMAHAWK at 240eur since it's been said to have very good power delivery but is it enough for this kind of 5900x overclock? Or just shell out 100eur extra for a MSI MEG X570 UNIFY?
I saw peak power consumption of ~185W (158A 1.17V) when running Prime 95 SmallFFT with AVX at 4550 MHz ruclips.net/video/bXyyESN87iM/видео.html. Any VRM that can handle that will be able to handle the overclocking.
I'm not a VRM expert, so best to check other channels for more information.
I tried the Prime 95 configuration and my 3D Mark Time Spy score dropped 800 points, XMP enabled, Z63 AIO, 3200MHZ CL16, at stock I hit 13,000+ on 3D Mark Time Spy.
This is expected behavior.
By default, the AMD CPU has a very aggressive single thread frequency boost. So, if you do a conservative all-core overclock (like the Prime 95 config) your actual frequency in lightly threaded workloads will be works.
This is a big drawback for AMD overclocking which is solved by DOS OC.
Awesome video. I did it and it works. Do I have to enable PBO for this ?
This one of the best OC videos for 5900x. I have a few question because I had some crash. I have a Mobo ROG CrossHero VIII (no black) with the latest fw First I tried with PBO and changing memory timings. When I try 16-16-16-16-36 I’ve got a crash, indeed it doesn’t boot. Maybe are my memories. I have 8x4 Adata Gammix D30 CL18 with high latency values of 17-18-18-20.. what you think? I should try a highest values? 16-17-17-19? Or buy new memories.
Following your tutorial , leaving the memory timings, , it was very stable at 4.5 with very good values in cinebench 23 or CPU-Z. However when I try 4.7 it boot up and then in windows I’ve got a BSOD.. strange. One thing I try after is the Dual Intelligence Processor 5 from Asus just to know what numbers it reach. Surprisingly when start the CPU temp rise immediately near 100%. I think this sw is not optimized for 5000 series. I have a Noctua D15.. it kept very cool my old 3700x.. maybe that was my limit and the cause of the crashes besides my memory latencies. Do you suggest to try another thing? Thanks! Great video. I really want to try the dual switch..
Thanks for the kind words!
Regarding the memory: what is the rated speed of your kit? If the timings from the video don't work, I would suggest to do the following: enable the XMP profile and set the DRAM ratio manually. This will set the memory frequency as you wish, and automatically configure the appropriate timings.
Regarding the BSOD: it sounds like you are limited by cooling. In my video example, I use custom loop water cooling so there's a bit more headroom. I would suggest the following: go back to the stable 4.5 GHz setting and start reducing the CPU voltage 10mv. Every step, go back in the operating system to check system stability and the temperature. If the temperature drops a lot, then maybe there is more headroom to increase the frequency again.
Best of luck!
@@SkatterBencher thanks for your advises. Yes, it seems that I don’t have to much headroom for cooling. I had to switch to full speed mode with my noctua DS 15 and the others Noctua on the cab ir order to manage 4.7 for a while. But at full speed is extremely noisy. Then I ran a performance test and it crashed again for overheating.
I was found a sweet spot with my old 3700x with the DIP5 of Asus. It runs all cores to 4.2 with 1.2v and never get over 65c. Now with my new 5900x enabling only PBO with some light task like game download and installation I see it reaches almost 69C with an average clock of 4.4/4.5 (two cores only at the highest speed) so I’m little confused with this processor. I would try your suggestion of keeping 4.5 and lowering the voltage. Sounds good.. i don’t like to see the voltage so high.. thanks and again great video!
After my pc did this it won't show display and I get the code fb on x570 darkhero
Hi what pbo limits are you recommending to keep it cool without limiting performances?
I have x570 dark hero and 5900x i do this manual but my pc its not booting what are wrong to my pc
With my x570 tomahawk. Do i need to put 12 pins cpu cables to the mobo or would 8 pins ok?
I always prefer to use both 8-pin and 4-pin, but in most cases just the 8-pin should be fine
@@SkatterBencher My power supply doesn't have the extra 4 pin even though it is 750W and supports two graphics cards. What's going on?
I’ve had another thought about this now that I’m actually working with a Dark Hero motherboard. Is it possible to use D.O.C.P. Defaults for RAM while using Dynamic Overclock Switching?I have a 3600 cl 14-15-15-35 kit trident neo kit
Yes it will work with DOS OC. DOCP is basically ASUS' way to enable XMP on AMD.
I have 5900X + Dark Hero motherboard. First time manually overclocking here, just got a question regarding DRAM Timing Control. I notice your settings are "16, 16, 16, 16 and 36"; what do I set for mine? My RAM 64GB (4x16) 3600Mhz CAS latency: 18-22-22-42, 1.35 V. Thanks.
I would suggest to not set the timings manually, but instead use XMP. On ASUS boards XMP is called DOCP.
This will set your memory automatically at the frequency and timings it ships with. If it's not stable, then still enable XMP/DOCP and manually set the frequency lower than DDR4-3600. 64GB is pretty massive so it may be that the system isn't fully stable at DDR4-3600 especially with FCLK running in sync.
Do you have any vid's using ASRock boards to Boost the 5900X?? I just ordered parts for a new 5900X build and I am using an ASRock B550 Velocita.. ?
I haven't touched an ASRock motherboard in ages, so unfortunately I don't have a guide available :(
@@SkatterBencher It's cool ASRock is making some pretty nice boards these days.. They have a great support community, they've been putting out BIOSs' for 5000 series on their Gen one x370 boards the whole time, When the other companies wouldn't.. Maybe one of these days you'll get your hands on a nice Taichi board or a phatom gaming baord..
Enabling Precision Boost makes my computer turn off and power back on when I’m away from my desk. It ignores the Power Settings in Windows at idle. I have the Dark Hero X570
Do you have any undervolt applied? If yes that's the reason, you will get random restart in idle if it's too undervolted.
@@TheClearStalker Nope, all I do is set a Manual Thermal Limit of 75 degrees Celsius. Not sure about Precision Boost because you can enable Precision Boost under the CBS/NBIO/XFR settings, AMD Overclocking/Precisión Boost and the Xtreme Tweaker menu. I’ve tried it different ways but it just doesn’t work at all with my settings. Maybe it’s because I set a manual voltage for my CPU... either way not sure. When I first tried it, it worked like a charm. But afterwards not so much. Random restarts. AND there are better settings but you can’t pick all. Best PBO is with a Negative 30 Curve Optimizer with a 75 degree thermal limit and Disabled Limits in the Advanced Menu but you can’t use Dynamic OC. But be sure to set the Idle Control to Typical or it will shut off during Idle. A Negative 30 Curve is an under volt. I like undercoating otherwise Precision Boost will overheat your CPU. My Dynamic OC is actually 44.25 ratio at 1.2v and it actually cools down my CPU when PBO raises it.
I am completely new to amd system. Witch oc mode would you recommend for gaming? I saw a gaming mode in ryzen master but it only runs with 6 cores active :/ I want a nice stable oc for daily use and mostly gaming. Need some guidance lol.. Is all core or pbo best?
It genuinely depends on your system. I would suggest to do the following:
1) Run a 5 to 10 benchmarks with PBO enabled, write down the performance numbers (preferably choose a variety of tests)
2) Find the maximum all-core stable overclock with your system and cooling
3) Run the same benchmarks again with the all-core stable overclock
4) Compare the performance results
What you'll likely see is that (a) in single-threaded and light workloads (i.e. certain games), PBO will give you higher performance; and (b) in multi-threaded and heavy workloads (i.e. rendering or excel formulas) the all-core OC will give you the highest performance. Then, make a choice :).
Dude sorry for the off topic question: I just order my dark hero. Does it need a bios update to fit a zen3 cpu or does it come updated? Thank you in advance.
Supports Ryzen 5000 series out of the box
SkatterBencher wow thx!
I tried this and it didn’t work. I have 4000mhz ram and it didn’t boot. I tried when I had just bought my Dark Hero Motherboard. I’ve since gotten acquainted with it and I paid more attention and realized that they can only get their 5900X overclocked to 4.325ghz with AVX stress test and I have mine running at 4.425ghz at 1.2V overclock completely stable on ROG Realbench.
I just tried the Auto with 4.550 CCX Dynamic OC. I scored my highest Cinebench R20 score ever. I’m sticking with it
The memory timings from the video might be a bit too tight for most sticks. It was an oversight from me - shouldn't have tuned those :).
You can always try just enabling XMP. That should help you tune the memory timings and Fclk frequency to enable DDR4-4000.
@@SkatterBencher I found out that by enabling PBO that it is unstable during idle. So the computer will shut off and reboot when I’m away from my desk. Only during idle. 45.50 ratio tops out at 85C and PBO tops out at 90C using my 420 eisbaer AIO. I almost reached 9thousand in Cinebench R20 by setting a negative -30 curve optimizer. But Curve Optimizer doesn’t work with dynamic OC. The computer also shuts down during idle so I set everything on Auto. I think that Enabling PBO the BIOS ignores the Power settings for windows and for idling. I had to leave PBO on Auto and enable Dynamic OC with a ratio of 44.25 at 1.2V for 70C temps with an R20 score of 8400. I was also able to reach a ratio of 1:1 but it’s only a 100-150 point increase in R20. With a 1:1 ratio it increases my SOC voltage and it increases my temps so I don’t have enough headroom to overclock. I think that your chart which says 4325mhz is more likely rather than 4550mhz. The CPU temps on the motherboard tell me 60C but the CPU Pkg is 70C so it’s difficult to configure fan curves when you place a thermal limit on PBO. I’ve played around with the settings a lot. I’ve learned a lot and this video helped me a lot too.
from your experiance you advise me to go with 5800x or 5900x for gaming?
I haven't done thorough game benchmarking, but I'd say either is gonna be fine. So, depends on your budget and of course availability
Hey, what is the reason you dont use the xmp / DOCP profile in the AI overclock tuner?
Somehow it didn't work well with this particular kit of memory.
I used DOCP in other AMD/ASUS videos like the Ryzen 7 5700G: ruclips.net/video/4gDfMwOBnoE/видео.html. Generally, I recommend using it.
Is 1.4v too high? Everyone is telling me to stay under 1.3v
This is a GREAT question! Let me expand a bit on this topic because it seems there's a lot confusion about this.
First of all, running higher voltages in itself is not a problem. In fact, by default CPUs are configured to run well in excess of 1.4V when aiming for the highest boost frequencies. You can check this yourself with Hwinfo.
Secondly, increased voltages become a problem when running longer, sustained, heavy workloads. Not only will it cause higher CPU power consumption but it will also increase the CPU operating temperature. This may affect the CPU stability, health and lifespan. That's why you'll see the CPUs reduce the voltage automatically. For example, in the toughest of workloads like Prime 95 with AVX the CPU voltage may be 1.0V or lower.
Third, what overclockers do is accept the risks associated with running out of vendor specification. So we accept that higher temperatures and higher power consumption may affect the stability, health and lifespan of the CPU.
Fourth, of course overclockers don't just accept the risk and move on. They try to mitigate the impact of taking the risks. One of the most common risk mitigations is improving the cooling. When you improve the cooling, for the most part you just increase the power budget. So, where a CPU would overheat at 125W with your regular cooling, with the better cooling you could run 150W without overheating. This better cooling allows us to set a higher voltage, which in turn allows us to set a higher frequency and get more performance.
In normal circumstances (read: unless you use extreme cooling), the highest voltage you can use safely will be limited by your cooling solution rather than the voltage itself being unsafe. The maximum useful voltage for overclocking will depend on your system, CPU, cooling and motherboard.
Hope this helps!
@@SkatterBencher Another question is - does this Core VID / Core Voltage specified the maximum value of voltage, not the constant one? Cuz I can track that when there is no load the voltage drops even to 300mV or does it specify the allowed peak voltage?
I would sell my Crosshair VIII Hero and get the Dark Hero if it was actually the MSRP but it's about $400 more (Australian), Asus stuff is always way overpriced here when it first launches.
What’s the difference about CrossHero VIII and the new Dark Hero?. I didn’t find much difference in the specs
@@martinfodor2848 No chipset fan, and also this Dynamic OC feature is only available on the more recent board. Better VRM as well. Otherweise they are similar.
My computer won't even boot up now. Horrible video 😂😂😂
It seems like in BIOS 3003 the settings change. I can't find dynamic oc switcher setting now.
Not at all? Or did they just move the segment somewhere else?
because of ryzen master i cant do this without bsod ryzen master made some permanent changes to the bios that cant be undone even if i change stuff in the bios ryzen master just changes it back i heard uninstalling doesnt even fix it lmfao
I am seeing other changing their LLC.. what is the point of the LLC and why didnt u change yours?
In an ideal world, the voltage supplied to the CPU cores would be stable. In the real world, there are always fluctuations up and down. LLC helps reduce the fluctuations.
It can help with overclocking when the fluctuation of the voltage goes too low and the frequency is not stable at that voltage. Using LLC will help avoid the voltage going too low. So, especially in situations with high workload it can be the difference between stable and not stable.
I didn't use it in the video because (1) the motherboard already has "auto-rules" configuring the LLC and (2) it's quite advanced already and my videos aims to help people get started.
Soo.. listen here.. I have a NZXT Kraken X73. 3600MHz CL16, PBO Enabled Cinebench R20 Score: 8190 and temps going to 85c and sometimes spiking a bit more.. what is wrong with my system?
85C is acceptable temperature, nothing wrong there :)
@@SkatterBencher it does spike to over 90 sometimes tho
Nothing to worry about still. I believe the max rated temperature for Ryzen 5000 is 95C. If your CPU would spike above that, the CPU will automatically downclock/downvolt to protect the CPU.
I want to buy the ryzen 9 5900x can i expect similar results in overclocking with a Asus Rog Strix x570-f?
You should be able to reach similar results on this decent motherboard. In reality in 95% it depends on CPU not MB.
Yes, but what about CPU degradation? Is zen3 good at that constant voltage applied? Will it degrade?
I'm not sure. I haven't seen any data yet on CPU degradation.
This is why I never overclock. Im happy with stock performance.
Blasphemy! 😜 (At least enable PBO and XMP?)
@@SkatterBencher Oh nevermind... I have those enabled. I meant more extreme OC.
Take a shot everytime he says '16'
By using the highest dynamic oc switching over clock in the video, does this raise overall cpu voltage? Could this introduce degradation to the life of the CPU?
Using DOS doesn't per definition raise the voltage. It just allows you to switch between Precision Boost Overdrive and OC Mode.
Precision Boost Overdrive generally does a good job maximizing the processor frequency in any type of workload. However, it's still more conservative than when manual overclocking. So generally you'll find that a manual overclock with fixed voltage and fixed frequency will achieve better results than letting PB manage. Especially if you have no issue pushing both the voltage and temperature to the maximum limit as PB won't do that.
So, if you set a non-conservative manual overclock with DOS OC, then the voltage and temperature for all-core workloads will indeed by higher than with Precision Boost. For semiconductors high voltage + high temperature are usually a cause for CPU lifespan reduction, though it's all relative. If your CPU goes from 10Y operation to 8Y operation, does it really matter?
@@SkatterBencher Thank you for this. Just bought a 5900x and got the best cooling i could without going custom. Primarily going to be gaming and i'm considering just mimicing the settings you used in the maximum manual all core overclock with DOS OC. Wanted to gauge any negative sideaffects of doing so. Cheers!
@@SkatterBencher For gaming OC, does it really matter if prime95 is stable or not? Could the non stable OC lead to unexpected crashing in this context? Thank you again 🙏
Have you tried 4000mhz memory with 2000 fclk? At the very least most 5900xs should be able to do 3800/1900
I quickly tried but couldn't make it work, sadly.
Unfortunately 8:41 motherboard didn't accepted this settings and 3 times restarted and run in safe mode
It could be anything. I would diagnose as follows:
1) leave memory at default, set the other settings
1a) if boots up -> memory issue. Try XMP instead of manual configuration
1b) if not boot -> reduce CPU ratio by 1, repeat until boot
@@SkatterBencher I have hyperx 3200mhz RAM and I set there you settings. I can't do that? 😂
If I have CL14 Trident NEO would I set the ram to 14-14-14?
Not necessarily. You can check what the timings are supposed to be in CPU-Z > SPD Tab > XMP column.
Is there anyway to raise the minimum ratio to 4.0ghz from 3.7 and raise from 4ghz to 4.425 with Dynamic OC?
I'm not sure I understand the question: why do you want to raise the minimum ratio?
@@SkatterBencher Well I think changing the default value from 3.7 to 4.0 will help if I set an FCLK of 2000 for my 4000mhz ram. It’s basically why 3600mhz ram is the sweet spot for a 3.7 cpu clock. I actually found the XMP settings for 1.8 or 3600mhz for my 4000mhz ram kit in the MOD software and it’s pretty impressive.
If it can process at a default 4000mhz and overclock to 4425mhz I get about the same results as when I am running a large heavy workload on PBO on Auto with the CPU throttling the frequency just before 95 degrees. Except with 4.0 and 4.425 it’s only a max 65 to 70 degrees for the same performance uplift.
The only better is a Negative 30 using Curve Optimizer, that’s a Low3-5mV for Minus 90millivolts when under load, and Minus 150millivolts when your CPU is not doing anything. My computer reboots when it’s in idle since it doesn’t get enough power to the CPU to stay on. Negative 30 according to the AMD bald guy is the max he said, in a video. It’s also on Optimum Tech. I almost reached 9thousand in Cinebench R20, I got an 8954.
I found out by Trial and Error that using my 4.0ghz default will boost to an Overclock of 4425mhz at 1.2Volts. In fact both frequencies can be reached with 1.2Volts but I have to disable the precision boost overdrive because I am trying to keep the Temperatures low, and PBO will stay on and it will not go to Dynamic OC since PBO raises the temps more than Dynamic OC.
The only thing I don’t understand when setting a Custom P0 State of 4025mhz Frequency, I don’t know what to set the VID at? I just left it at 38 VID because that’s what it was before. I don’t think that is right but I don’t know. Thanks for you guidance by the way, I really like the Dark Hero motherboard!!! 👍
Do you know if other MB will have this feature in the future?
Possibly. Enabling DOS OC requires PCB-level changes so it cannot be backported to older boards. But for future boards, why not.
When using DOC, do you leave the Core and core voltage settings in main menu?
When using DOS OC it is recommended to set the CPU voltage by changing the Core VID setting in the CPU Core Ratio (Per CCX) menu.
@@SkatterBencher thanks! I have an issue with idle temps however
When using a fixed vcore, 4.6@1.2, temps are idle at 37 to 40 and gaming around 50c
However when i use pbo / curve etc it's around 50 to 60 just on desktop... Any idea why?
Hard to say, I would guess PBO is setting a higher voltage than 1.2v resulting in temperature increase
Do you know how much power is consumed by the entire configuration
Sorry, no, I didn't check
Can u make a video with the same processor and 3200 ram?
If you have different RAM, simply use the XMP option and the BIOS will configure it for you. Everything else should be the same :)

Clear CMOS to reset the BIOS, then try again with lower settings (and without changing the memory settings)
wow, 5900x goes higher than 5950x. wonder what the 5600x will peak at- 5 ghz all core?
I doubt it. My 5800X only reached 4775 MHz, so marginally higher than 5900X (video up tonight). I just got a 5600X and will try it out tonight. If it can do 4800 I'll be a happy man!

@@rubbersoul420 Okie dokie, last question did you do any PBO settings changes? There's a curve priority and "boost priority" and people are changing numbers getting which core boots the quickest and overclocking that one more than the others or can I just mobo settings and call it a day?
@@jonahjameson272 it’s been very stable for me, even more so now that there’s a new non-beta bios. I couldn’t say about oc’ing the chip though as I just have my ram overclocked.

Is it necessary to disable PBO before going on to Step #2?
You don't need to manually disable PBO as the system will automatically do it when you start manual overclocking.
On AMD systems, PBO and OC are two different "modes". So when using the one, you won't be able to use the other. Except of course with Dynamic OC Switching.
@@SkatterBencher thanks so much! This video was incredibly helpful, especially with the dark hero motherboard. Definitely will keep an eye on this channel 😁
Any Infos of other boards getting this feature?
Dynamic OC Switching will be a Crosshair VIII Dark Hero exclusive feature. Reason is it requires a PCB level change and without it this feature can't be implemented
Not really needed by looking at the numbers, 4.75 manual oc was the same numbers apart from one
