Before asking you what I want to ask let me first tell you that you are the very best overclocker educator I have ever seen and your metodological aproach to overclocking is everything anyone would hope for. The quality of the information you put into these videos is quite amazing, gold literally. Sad so few people know about you and your channel. I think this is simply a question of time. Now, about my question: Please consider deliding the 7950x3d and then overclocking it to see how the improved thermal margins affect the overclock potential.
Hi Pedro, thanks for the kind words. I really appreciate it! I don't think I've ever delidded a CPU before, so I'm a little hesitant ... but I might consider it (for science!). Thanks for the suggestion.
@@SkatterBencher Ok, so if you end up doing it Der8auer sells a tool that makes deliding very easy and he posted a delid video of the 7950X3D. A previous video analysis of deliding a 7950 ( also from Der8auer ) showed a huge drop in temps when used bare core on block, and this is the reason I think it may be worth the effort.
@@SkatterBencher If you delid it use some sort of conformal coating on everything but the cores and I/O chip + take into account that the IHS height is removed and make proper modifications to fit the cooler flat on the dies last but not least try to do that with the 7950x too :P
@@DragonOfTheMortalKombat intel fans don't like anything that's different than the way intel or Nvidia do things😂(yes I included Nvidia on purpose in this statement. We all know it to be true.)
The 7950X3D may not clock as high as the Intel 13900KS, but it’s the most power efficient CPU I’ve ever seen in action! Tempted to switch. Update: Switched from 10900K to the 7950X3D!
Power efficiency I didn't even though it is possible to get from the new high end cpus. I've got the 7800x3d and it consumes under 50w no matter what I do to it. During CPU-Z stress test I get 6700 score with 55W consumption. With my 4.4 ghz oc 5820k I didn't measure, but I expect into the 150-200w for a 1600 score or so. I am just blown by the performance of the 7800x3d given the fact that it only got 2 more cores (4 threads) and it clocks at around 4.8-5 ghz. If i were to not OC the 5820k, I would get around 1200 score, 1300. With the 7800x3d I get 1200 with running one core/2 threads only.. Just amazing
This was a good video to understand the mechanics behind how the cpu behaves. Now we all can't copy each other's CO settings (silicon lottery), I just did a safe CO of -15 all cores & and Fmax of +150 & PBO was set to Manual (I only changed and set my PPT to 150w to stay away from diminishing power returns). I hit the 5900mhz on 3 non Vcache cores, others max out at like 5800-5875mhz. The system is stable under all conditions including High and more importantly the lower workload scenarios where many aggressive CO settings give too little voltage to the cores and crash the system. In the past with Ryzen overclocking found that when I set CO negative too aggressively, it's the lower workloads where the CCDs clock lower and you end up too low left on the VF curve and receive too little voltage for those lower frequencies and boom you crash. So be mindful that stability is not only at the high usage use case, but also the lower usage use cases. The Cache CCD, all cores hit 5250mhz. Max temp under Cinebench 10min multi core is around 79C with a Noctua Air cooler NH-D15 (with H-2 paste) in a Fractal Design Torrent case (So airflow to the max). I didn't want to check each core for WHEA errors and tune it further so i went the lazy all core route; I'm happy with it. This 7950X3D is truly an efficiency king, and a jack of all trades.
Unfortunately running Cinebench “stably” doesn’t mean much as it isn’t a properly stressing test. So in reality your modification using air-cooling will probably be less than your lazy attempt. -10 already is quite taxing.
Thank you so much for this video! I didn't have time to tweak each core so I applied all core negative offset -15 to my 7950X3D and BAM! Hit 5.2 ghz all core during gaming. I am using the same board as you with the LT720 cooler!
This class is interesting. Geeting to know something that you have never even know what is all about. Looking forward for the next video. I have done pretty well oc on my 13700k ..as a beginner because of this channel. Thanks.
The heterogenous ccds makes overclocking very difficult, I hope you make a video for the upcoming 7800x3D as it should both be simpler and more popular.
For those struggling on later bios make sure you set pbo power limits. On the Asus x670e-e I think they limited it on auto. There should be a screenshot of what they should be on the scatterbencher page for the 7950x3d. Once i set TDC to 160 my numbers went up.
Hey Skatter. Thanks for your tutorials! I have a pretty good chip -I managed to get my 7950X3D boosting to 5960 mhz with -40 CO. Around 80W usage in games :) I'm super happy with it, awesome upgrade after 5900X for 4k gaming / VR / rendering
@@zoeydee7168 All cores. Although on the newest bios from Gigabyte -40 was causing instability in long gaming sessions. -30 seemed fine, but I downgraded the bios:)
@@spiriter666 awesome. Thank you for following up as I have been tweaking mine as well and -30 might work for me, ie, -35 seems fickle and unstable in, I think, low loadings
eclk 1 mode! wow! We can now overclock locked cpu's without breaking the rest of the system! Now we just need to find a way to trick the voltage limit on the x3d ccd at low temperatures.
To the uneducated, you make it sound like ECLK is a feature of every AM5 motherboard. It is not, only the most expensive, highest-end boards have it. It's important to note this for potential buyers, who are not following closely the scene. If you plan on getting 7800X3D with a decent B650(E) board (like myself), don't expect to find the ECLK / Asynchronous Clock feature. We're left with only the PBO2 and Curve Optimiser strategy.
Very very in depth video. Extremely well done! Two questions I had, would your #3rd overclocking method benefit from deliding the CPU and ultimately enable higher stable clocks? Second question min 13:05, I dunno if I got this right. Technically speaking does that mean a (simular binned) 7800x3d will performe better (up to 8 cores ofc) than a 7950x3D cause it has a favorable Voltage for the 3d vcache CCD only? Hope those questions weren't confusing or kinda wrong. Tysm in advance!!!
2nd question. We won't know 'til that part drops. Your favourite techtuber breaks NDA; you see that techtuber reviewing that company's goods no more. Wait for real-world results from your favourite techtubers. Theoretical answers have a good likelihood of being wrong.
As far as I understand AMD's Precision Boost algorithm, lower temperatures will always help to achieve higher frequencies. That's because it would allow running a different VFT point. X voltage for Y frequency at Z temperature -> lower Z means higher Y. That said, I think the main limiter for the 7950X3D isn't temperature since in none of my OC strategies I hit the TjMax of 89C. The main limiter is the allowed CPU voltage for the V-Cache CCD. Can't answer the 7800X3D question since I haven't tried it yet, but I assume it's a similar situation like with the X-SKUs where the best CCDs go into the Ryzen 9 and lesser CCDs go into the Ryzen 7/5s. I assume the V-Cache VID limit with 7800X3D will be similarly constraining, just that 7800X3D has lower Fmax. Unfortunately, but also a little excitingly, if the positive Fmax boost offset is also locked on 7800X3D, it means Async ECLK will be the only viable path for overclocking.
As someone already said. Please consider delidding a cpu. You make the best oc videos I have seen. But the lowered temps could make it even more Interesting.
Extrapolating on your numbers, it sounds like the 7800X3D might be able to hit ~5.5GHz on a 105 ECLK. That sounds extremely compelling, at least for people who aren't doing productivity workloads.
7800X3D has a listed maximum boost frequency of 5 GHz, so I assume the fused Fmax will be 5050 MHz. Also assuming the Fmax Boost Override will be locked, then 105eclk will give you ~ 5.3G Based on my limited experience with this 1 X3D sample and inferring from the conservative boost clock of the 7800X3D, I think the V-Cache is very sensitive and tricky to overclock. I would probably expect V-Cache CCDs to not clock much higher than 5.45G for the best ones and 5.15G for the worst ones.
these settings didn't work for me, but the video did nudge me in the right direction. i ended up with -15 offset on all cores, and +100 mhz. that's the best i could do with my 7950x3d. thanks a bunch
Hey man! First of all, nice work! Your video/instructions were clear and precise. Tks and keep up! One doubt If I use the second strategy to OC mine, should I use Asus core flex and should I set the SMU to driver too?
It's not a must to configure Core Flex to use OC Strategy #2. Core Flex and the SMU option control which CCD gets priority for certain workloads. My OC Strategy #2 just help squeeze a little more performance out of the CCD.
Can you please do a 5 min video of how to setup the 7950X3D for best V cache/gaming optimization? I’m sure this is what mostly folks will be looking for.
I am watching your channel for the 1st time today. Very detailed and informative strategies to approach this specific chip from AMD for optimising. I wonder if you have access to any other motherboards for AM5 and what specification on the Rog made you choose that motherboard.
Can you please link your per core SP values? my x3d has a SP score of 110 and yours has a sp of 111. Somehow you can undervolt wayy lower then me. i get crashes on -5 on the x3d cores
what's your fave cpu skatter? if u was serious about gaming and could get only one? what platform? what cpu? thanks for your work... been watching a min now..
I think right now my favorite CPU is the 13900KS+Z790 due to the overclocking headroom with the TEC and the comprehensive set of overclocking tools that comes with the CPU.
Amazing content. Glad i run into your channel! Question - is there a strategy to identify the better cores! Also on strat #3, what was your thinking for setting the positive voltage on the cores? Why did you group them as you did? Once again, outstanding content and well presented!
The only working strategy (I've found) is testing them yourself, unfortunately. In OC Strategy #3 I use Eclk to overclock the CPU. When using the Eclk, we effectively increase the frequency of a V/F point. So, if the V/F point was 5000 at 1.25V, with 101 MHz ECLK it's 5050 at 1.25V. Some cores may not be able to have their V/F curve adjusted too much and become unstable due to too low voltage for a certain frequency. With a positive curve optimizer, we can offset a core's V/F curve to use more voltage. So let's say that 5050 isn't stable at 1.25V, with a CO of +5 maybe the voltage is 1.275V and then the core is stable again.
SkatterBencher I have a question, for the past few days I have been attempting all iterations of your overlocking on my 7950X3D on a B650 AORUS Elite Motherboard. I have compared and contrasted multiple videos from yourself in which you either use my CPU or my Motherboard. I swear I am doing the correct things but I can seem to get a better average GHz than around 4.7 - If you have an idea for what I could be doing wrong I would greatly appreciate the help.
Great video! QQ: Why do you recommend these very specific CO negative offsets? I thought every CPU would be different, would love a similar guide for the 7800x3d when launched!
You're right that every CPU has different optimal CO negative offsets. I try my best to highlight in the video that one shouldn't 1:1 copy the settings and apply to their system, but it's not easy. I decide to still show the settings because it may help people feel more comfortable using those tools
I see in your segment for strategy #2 for Curve Optimizer, you have 25 shown as a selection for core 7, but then state it should be 35. Pointing this out to get clarification so others know. Thanks for these informative videos btw. I am trying to get mine to do strat #2, but it BSODs :( (all BIOS settings cleared b4 and followed as dictated) Edit: can you do a video on how to oc using strat #2 curve optimizer for individualized silicon? ty
Oops, thanks for letting me know. I will pay more attention to the curve optimizer settings for next videos. I've long had it on my backlog to make a video on how to do manual curve optimizer testing. Just haven't gotten around to do it ... :(
I feel an aggressive undervolt would actually bring up those frequencies much higher while reducing temperatures and increasing performance without the need to overclock and increase power
Thanks! I am going to try to find the best setup for gaming. I have Asus o x3D gaming settings on. But want to figure out what's best. Star Citizen loads first on CCD1 and switches to CCD0 when ingame. The game is limited by the rendering thread, and to get the best performance I think it need to run that on the fastest core, don't know how much cache it needs. Overall I have only seen about max 35w usage. I know a little here and there, but need to get my brain to rap around hwmonitor, look at performance. I used Asus windows and did a setting there that really screwed me over. A bios reset didnt even help. Exbo 1 suddenly also didn't work, so using number 2, but could not see any difference in settings applied. 6GHz C30 Corsair hynix. I should have gone for an Intel setup since I need a better 1 core performance. But that ahip is sailed now. I upgraded from a Ryzen 1600x!
please consider adding benchmarks for msfs and dcs. in the past, the 5800x3d showed remarkable gains for these titles. the 7950 x3d offers an interesting option. you could disable the v-cache ccd or the plain ccd. thus you have controlled for all other variables(memory, voltages, power supply, etc) to see the impact of cache alone
For video editing in apps like adobe premiere , after effects and DaVinci Resolve which CPU is the best for performance? I9 13900K , 13900KS or AMD 7950X or AMD 7950X3D?
I just do not understand why my bios looks different from yours even though we have the same motherboard... Like I do not have many of the options you have such as onboard devices configuration or core flex.
The video starts 13:40 for messing things in BIOS Sure you just wanna get the good OC or undervolting values for your CPU, i don't wanna learn what the definition of CDC or MASTER & SLAVE etc again video starts 13:40
I still like to watch people over clock cpu to showcase how much headroom it has . To some extent it mean reliable. But oc cpu dont really give much performance has it used to.
What test software did you use to determine the per-core negative offsets? I could just use yours, but you say (understandably) that they may not be the best for my particular CPU. I'm currently running -30 offset on all cores, but I'd like to experiment with per-core offsets.
The test software will vary depending on the architecture and even sample. When we use Curve Optimizer to undervolt, we need to find the weakest link for our CPU. Sometimes that's all core heavy AVX, sometimes it's single core SSE, and sometimes it's even idling at desktop. I'll typically try first exploring with OCCT where I can define test scenarios for SSE, AVX, AVX2, and AVX512 for both all core and per-core. In the initial Curve Optimization process, I also use dynamic benchmarks like AI Benchmark, Geekbench, or the Y-Cruncher stress test to see if anything triggers instability after undervolt.
First thx for the great and detail explainantion, with your help I am starting to be able to OC my firt AMD CPU , What is your setting for the 2 minutes test with Corecycle ?
An interesting experiment, if possible, would be restricting CCD1 to the same 1.2V and seeing how the maximum frequency compares to CCD0. I'm guessing that FMAX limit on CCD0 is due to the v-cache timing achievable at the voltage limit? (And that voltage limit set to protect against damage) Awesome channel BTW!
For video editing in apps like adobe premiere , after effects and DaVinci Resolve which CPU is the best for performance? I9 13900K , 13900KS or AMD 7950X or AMD 7950X3D?
I just upgraded my i9 7980xe seven-year-old to 9 7950x3d. I got around 20 to 30% improvement. I appreciate seeing Ryzen running with a fraction of the power, but that was completely disappointing. Precision boost overdrive 😂 drives Ryzen to much lower than what was mentioned in AMD marketing documentation. I hope I am missing something and come back and change this feedback. Meanwhile, I see tons of marketing from AMD and much less performance. It is Intel going behind that made the opportunity for AMD. Now, speaking pure business, AMD is doing the correct thing, as energy consumption is the key, knowing that the world is going mobile. Desktops are secondary, and for gaming, they are being eaten by consoles. AMD looks stable and robust, and this makes it a winner l. BUT, a real jump in performance is an unmet wish.
I just gone with i9 13900k and 4090 gaming oc asus ^^ im not specific fan, but i think 7950x3d should be better instead of having low 1% fps and probolems with 2 ccd's, this time intel ^^ last time got gaming notebook with ryzen :D
7800X3D est le seul CPU en 7000 digne de l oc vue que un seul CCX activer donc pas de problème avec Windows et l oc apportera surement un meilleur FPS Merci de tester ce 7800X3D a sa sortie et contrairement au 7900X3D et 7950X3D qui ont du 3DV cache uniquement sur un CCX ses 2 CPU auront bcp de problème avec la gestion Windows ainsi que les jeux il aurai été plus judicieux de mettre du 3DV Cache dans les 2 CCX pour avoir un gap bien meilleur mais un gros problème existe sur le détail donner par AMD le 7800X3D n a un boost max de 5.0 GHZ et pas d oc manuel donc ses 2 grand frères équipé de 2 CCX un avec 3DV cache quel vitesse a celui ci ??? vue que l autre CCX va a 5.6 GHZ au 7900X3D et 5.7 GHZ 7950X3D la partie 3DV Cache limitant exactement comme le 5800X3D ,sur ses nouveau 7000 le risque est que Windows pilote la fréquence max du CCX sans 3dvcache alors quel GAP en FPS a espérer Merci pour vos tests , amicalement 👍
So ECLK doesn’t affect other devices like USB and SATA, meaning it’s safe for daily use? Also, the theoretical maximum speeds you can get sound like 6250 (non3D) / 5500 (3D) using PBO + ECLK. is that right?
Reference clock tuning doesn't affect anything except for the CPU clocks, but only if you're in ECLK1 mode. It's indeed safe for daily use. If you're overclocking the reference clock in ICLK (internal clock) or ECLK0 mode, then it will affect those parts. Theoretical maximum speed would be higher since ECLK can go pretty high. I achieved 170 MHz on water cooling at launch valid.x86.fr/ilmj1v. Let's say you stick to 110 MHz ECLK and a 200 MHz Fmax boost override, then the 7950X3D frequency would be 5775 (3D) / 6545 (non-3D).
Hey skatterbench, I was wondering if you could tell me your sp rating for each core on your ROG board for CC0 (vcache) die in the ai features section of the bios under extreme tweaker header. My rog board gives the same OVERALL sp rating, but id love to know the per core as i would like to further tune your method 2 towards my silicon. Thank you so much for the guide. It was a great introduction to my interest in amd cpu oc
@@SkatterBencher thank you so much. I really appreciate the thought alone! I just wanted to know if you followed the method of most undervolt on worst cores and least undervolt on best cores as well as see how to adjust your curve to mine
I don't really pay much attention to SP when it comes to final tuning of the chip. SP tells you about the P0 VID, but it doesn't tell you about the overclocking capability. I've seen "weak SP" cores overclock much better than "strong SP" cores. So, when it comes to chip-specific tuning ... I just try all of them and see where I end up.
Not much higher than when the non-3D CCD is enabled. The highest I've seen is 5.5G+ but it was obviously not very stable. The 3D V-Cache is tricky to overclock :)
@@SkatterBencher I'm seeing the same behavior now that mine came in. Some notes from my setup/testing thus far. Asus ROG Strix X670e-i seems to be missing the eCLK setting in the bios. Enabling the memory learning setting like we did with the 7600x for faster boot times led to some very poor memory stability. My temps hit 90° rather quickly on this chip with the thermalright pressure plate. I may try the stock bracket to see if that helps, but did you hit 90° while benchmarking?
Hey SkatyerBencher, can you please let me know if you are getting Q code 8F with recent Bios and 7950X3D? I have this Q code which I have no idea what it means. Everything works and boots up perfectly though.
Curve shaper is the only thing I've been playing with for the past two weeks. I think it fundamentally changes the advanced overclocking strategies for Ryzen CPUs. However, I haven't yet come up with a good methodology how to use it in practice. Will feature for sure in future videos!
I tried the 2nd strategy using your PBO curve optimization settings. I got similar benchmark scores (37,224 in Cinebench R23) but started seeing random crashes, especially when gaming. Hopefully one of the other methods works better with my silicon.
Did you copy the same curve optimizer values? If yes, please don't :). Every CPU is different so the Curve Optimizer values will be different too. The only way to finetune using Curve Optimizer is by check the stability for each core.
Thanks for the guide! I didn't understand the 2 step at 31:16 . By that time we have positive all-core CO but the first bullet says "increase per-core NEGATIVE" CO. And next bullet again increases values but of positive CO. Shouldn't we use positive at every step in ECLK process? Shouldn't it read as follows? - increase all-core positive CO until unstable - if unstable decrease per-core positive CO
Hi! I looked back at it and it's indeed a bit confusing. The idea here is that in step 1 we identify the frequency limit across all-core and in step 2 we're trying to do it for each core. We assume that in step 1 we'd be too conservative with the best cores, therefore in step 2 we try to reduce the curve optimizer. This will make it boost higher. However, for cores that remain unstable, we need to further increase the curve optimizer. Hope this makes it a little more clear.
Does anyone know if the V cache CCD on the 7900x3d has the same fixed freq cap (5250) as shown here for the 7950x3d? Since it has fewer active cores I was wondering if it might have a slightly higher fixed cap, which might be a good trade off if you don't regularly need all the additional cores of the 7950 for productivity.
It has a lower cap, AMD's website says 5000. I imagine you might be able to push it higher than the 7950x3d with good ECLK tuning, but I also think the better binned chips are going into the 7950x3d so it's probably less likely you'll get a chip you can really push that hard.
The thing that I haven't figured out is how you test the strength of each individual core so you can fine tune at a core level. Is it just trial and error?
Can't you manual oc the CPU with the asynchronous bclk Mode? Just set the multiplier to whatever you can set it to (for example 50) and tune the Bclk with asynchronous mode (for example 110mhz). Thats then 5500mhz allcore. Vcore 1,2v should be enough for that 🤔
@@thecolossus_5917 but you can set the Bclk with asynchronous mode to like 140mhz. On locked Intel chips you can still set the multiplier, but not higher than the boost clock of the chip. Isn't it the same here? Even if you can only set the baseclock multiplier of 40 you still could do around 5,6ghz allcore (140mhz bclk)
Hello It was a very instructive post. I am collecting systems after a long break. And I have been away from most technology and I have been using the z270 intel platform for 6 years, so I have a question, my system parts will be completed in a few days. I'm waiting for 7950x3D and my motherboard is Asus x670e hero. There was an issue that stuck in my mind, my memories are 4 sticks 16-16-16-16. I bought 2 dual channels. Gskill F5-6000J3038F16XS-TZ5NR. It's expo approved and it's on the motherboard's list, but I'm wondering if 4 sticks will cause problems. I've read a lot of people who have problems with corsair brand memories. There were those who used 4 sticks in Gskill memories, but there were much less writes than corsair memories. I couldn't come to a definite conclusion. I will be glad if you share your information and opinions.
I'm far from an expert on memory overclocking and tuning, so unfortunately I don't think I'm well-placed to give you an educated answer. I can recommend Buildzoid as a good source for this kind of information
Have you tried lowering the base frequency of the cores with cache (underclock), for example to 4.0 ghz, and raising the frequency of the others. Could that be possible?
ECLK mode is a feature available for Raphael (Zen 4) CPUs to use an external clock generator instead of the internal clock generator. It is up to the board manufacturers to decide whether to add those clock generators to the boards or not.
Do you agree that ryzen 7 is ram latency sensitive ? I've seen many videos showing huge improvements replacing ddr5 cas 40 for a cas 30 on the same frequency
There's a measurable difference both in benchmarks and real-world scenarios, like gaming. The difference between say, 6000 CL40 and 6000 CL30 is pretty substantial (assuming sub-timings are equal). Whether or not it would qualify as being "huge improvements" is kind of subjective, but there's certainly a noticeable difference.
Do the worse cores on the X3D CCD need the higher positive CO value to operate stable with ECLK attempt? So i can check the hierarchy of the cores and go from there?
In my experience, the CPU core overclocking capability does not differ between X3D and non-X3D CCDs. It's just that they're limited by the V-Cache in frequency and temperature.
Before asking you what I want to ask let me first tell you that you are the very best overclocker educator I have ever seen and your metodological aproach to overclocking is everything anyone would hope for.

The 7950X3D may not clock as high as the Intel 13900KS, but it’s the most power efficient CPU I’ve ever seen in action! Tempted to switch.
Update: Switched from 10900K to the 7950X3D!
I'm thinking of building a system out of this board and that chip
Want to final form my x570 5600x to a 5800x3d first though
Power efficiency I didn't even though it is possible to get from the new high end cpus. I've got the 7800x3d and it consumes under 50w no matter what I do to it. During CPU-Z stress test I get 6700 score with 55W consumption. With my 4.4 ghz oc 5820k I didn't measure, but I expect into the 150-200w for a 1600 score or so. I am just blown by the performance of the 7800x3d given the fact that it only got 2 more cores (4 threads) and it clocks at around 4.8-5 ghz. If i were to not OC the 5820k, I would get around 1200 score, 1300. With the 7800x3d I get 1200 with running one core/2 threads only.. Just amazing
This was a good video to understand the mechanics behind how the cpu behaves. Now we all can't copy each other's CO settings (silicon lottery), I just did a safe CO of -15 all cores & and Fmax of +150 & PBO was set to Manual (I only changed and set my PPT to 150w to stay away from diminishing power returns). I hit the 5900mhz on 3 non Vcache cores, others max out at like 5800-5875mhz. The system is stable under all conditions including High and more importantly the lower workload scenarios where many aggressive CO settings give too little voltage to the cores and crash the system. In the past with Ryzen overclocking found that when I set CO negative too aggressively, it's the lower workloads where the CCDs clock lower and you end up too low left on the VF curve and receive too little voltage for those lower frequencies and boom you crash. So be mindful that stability is not only at the high usage use case, but also the lower usage use cases.
The Cache CCD, all cores hit 5250mhz. Max temp under Cinebench 10min multi core is around 79C with a Noctua Air cooler NH-D15 (with H-2 paste) in a Fractal Design Torrent case (So airflow to the max). I didn't want to check each core for WHEA errors and tune it further so i went the lazy all core route; I'm happy with it. This 7950X3D is truly an efficiency king, and a jack of all trades.
My asus 670 won't let me pbo
Unfortunately running Cinebench “stably” doesn’t mean much as it isn’t a properly stressing test. So in reality your modification using air-cooling will probably be less than your lazy attempt. -10 already is quite taxing.
your knwoledge is amazing, thanks for the vid
Oh nice. I just ordered the same motherboard last week. Stoked to watch the rest of this video now.
::edit:: Nice, same memory sticks too.
Enjoy the board!
I got the gene, glad I decided for a board with external clock gen
Thank you so much for this video! I didn't have time to tweak each core so I applied all core negative offset -15 to my 7950X3D and BAM! Hit 5.2 ghz all core during gaming. I am using the same board as you with the LT720 cooler!
Nice!
@@SkatterBencher Can you please do a video on Core Flex bios settings?
This class is interesting.
Geeting to know something that you have never even know what is all about.
Looking forward for the next video.
I have done pretty well oc on my 13700k ..as a beginner because of this channel.
Thanks.
Exceptionally good information!
The heterogenous ccds makes overclocking very difficult, I hope you make a video for the upcoming 7800x3D as it should both be simpler and more popular.
Thanks for the suggestion, I will try :)
Since it homogeneous it's going to be essentially the same as doing it on 5800 x 3D except now you have asynchronous clock, therefore it's easier.
For those struggling on later bios make sure you set pbo power limits. On the Asus x670e-e I think they limited it on auto. There should be a screenshot of what they should be on the scatterbencher page for the 7950x3d. Once i set TDC to 160 my numbers went up.
I want to get b650e motherboard as i want to start learning overclocking
Any recomendation
Some says b650e aorus master is the best???
Hey Skatter. Thanks for your tutorials! I have a pretty good chip -I managed to get my 7950X3D boosting to 5960 mhz with -40 CO. Around 80W usage in games :) I'm super happy with it, awesome upgrade after 5900X for 4k gaming / VR / rendering
Nice, what a great chip!
Did you use -40 for all cores or just specific ones, ie, have the same here and dying to know.
@@zoeydee7168 All cores. Although on the newest bios from Gigabyte -40 was causing instability in long gaming sessions. -30 seemed fine, but I downgraded the bios:)
@@spiriter666 awesome. Thank you for following up as I have been tweaking mine as well and -30 might work for me, ie, -35 seems fickle and unstable in, I think, low loadings
eclk 1 mode! wow! We can now overclock locked cpu's without breaking the rest of the system!
Now we just need to find a way to trick the voltage limit on the x3d ccd at low temperatures.
At least a real clear unbiased journalistic review, thank you sir for delivering ! I would love to see what all core OC you can achieve.
To the uneducated, you make it sound like ECLK is a feature of every AM5 motherboard. It is not, only the most expensive, highest-end boards have it.
It's important to note this for potential buyers, who are not following closely the scene. If you plan on getting 7800X3D with a decent B650(E) board (like myself), don't expect to find the ECLK / Asynchronous Clock feature. We're left with only the PBO2 and Curve Optimiser strategy.
Very very in depth video. Extremely well done!
Two questions I had, would your #3rd overclocking method benefit from deliding the CPU and ultimately enable higher stable clocks?
Second question min 13:05, I dunno if I got this right. Technically speaking does that mean a (simular binned) 7800x3d will performe better (up to 8 cores ofc) than a 7950x3D cause it has a favorable Voltage for the 3d vcache CCD only?
Hope those questions weren't confusing or kinda wrong. Tysm in advance!!!
2nd question. We won't know 'til that part drops. Your favourite techtuber breaks NDA; you see that techtuber reviewing that company's goods no more. Wait for real-world results from your favourite techtubers. Theoretical answers have a good likelihood of being wrong.
As far as I understand AMD's Precision Boost algorithm, lower temperatures will always help to achieve higher frequencies. That's because it would allow running a different VFT point. X voltage for Y frequency at Z temperature -> lower Z means higher Y.
That said, I think the main limiter for the 7950X3D isn't temperature since in none of my OC strategies I hit the TjMax of 89C. The main limiter is the allowed CPU voltage for the V-Cache CCD.
Can't answer the 7800X3D question since I haven't tried it yet, but I assume it's a similar situation like with the X-SKUs where the best CCDs go into the Ryzen 9 and lesser CCDs go into the Ryzen 7/5s. I assume the V-Cache VID limit with 7800X3D will be similarly constraining, just that 7800X3D has lower Fmax.
Unfortunately, but also a little excitingly, if the positive Fmax boost offset is also locked on 7800X3D, it means Async ECLK will be the only viable path for overclocking.
As someone already said. Please consider delidding a cpu. You make the best oc videos I have seen. But the lowered temps could make it even more Interesting.
Thanks for the suggestion, will consider it :)
Extrapolating on your numbers, it sounds like the 7800X3D might be able to hit ~5.5GHz on a 105 ECLK. That sounds extremely compelling, at least for people who aren't doing productivity workloads.
7800X3D has a listed maximum boost frequency of 5 GHz, so I assume the fused Fmax will be 5050 MHz. Also assuming the Fmax Boost Override will be locked, then 105eclk will give you ~ 5.3G
Based on my limited experience with this 1 X3D sample and inferring from the conservative boost clock of the 7800X3D, I think the V-Cache is very sensitive and tricky to overclock. I would probably expect V-Cache CCDs to not clock much higher than 5.45G for the best ones and 5.15G for the worst ones.
these settings didn't work for me, but the video did nudge me in the right direction. i ended up with -15 offset on all cores, and +100 mhz. that's the best i could do with my 7950x3d. thanks a bunch
bclk OC of a 7800X3D sounds promising
Agreed :)
theres risk of damaging the 3d cache, i wouldnt oc an x3d
Damn I feel disappointed in myself i just found you out right now. Thanks to tomshardware for sending me your way. Great freaking video.
An update with new agesa version would be helpful.
Nice job as usual! :D
Hey man! First of all, nice work!
Your video/instructions were clear and precise.
Tks and keep up!
One doubt
If I use the second strategy to OC mine, should I use Asus core flex and should I set the SMU to driver too?
It's not a must to configure Core Flex to use OC Strategy #2. Core Flex and the SMU option control which CCD gets priority for certain workloads. My OC Strategy #2 just help squeeze a little more performance out of the CCD.
you deserve a millinon subs my brother
Can you please do a 5 min video of how to setup the 7950X3D for best V cache/gaming optimization? I’m sure this is what mostly folks will be looking for.
Yes Please 🙌
Watch the video again...
I am watching your channel for the 1st time today.
Very detailed and informative strategies to approach this specific chip from AMD for optimising.
I wonder if you have access to any other motherboards for AM5 and what specification on the Rog made you choose that motherboard.
No particular reason why I picked the X670E Extreme. I just figured it's a good match for AMD's most high-end chip :)
Can you please link your per core SP values? my x3d has a SP score of 110 and yours has a sp of 111.
Somehow you can undervolt wayy lower then me. i get crashes on -5 on the x3d cores
what's your fave cpu skatter? if u was serious about gaming and could get only one? what platform? what cpu? thanks for your work... been watching a min now..
I think right now my favorite CPU is the 13900KS+Z790 due to the overclocking headroom with the TEC and the comprehensive set of overclocking tools that comes with the CPU.
@@SkatterBencher thank you sir... ill save up lol im still on i712700k

Wow this guy is good
Hi intel core i9-13900ks ❤
Amazing content. Glad i run into your channel!
Question - is there a strategy to identify the better cores!
Also on strat #3, what was your thinking for setting the positive voltage on the cores? Why did you group them as you did?
Once again, outstanding content and well presented!
The only working strategy (I've found) is testing them yourself, unfortunately.
In OC Strategy #3 I use Eclk to overclock the CPU. When using the Eclk, we effectively increase the frequency of a V/F point. So, if the V/F point was 5000 at 1.25V, with 101 MHz ECLK it's 5050 at 1.25V. Some cores may not be able to have their V/F curve adjusted too much and become unstable due to too low voltage for a certain frequency.
With a positive curve optimizer, we can offset a core's V/F curve to use more voltage. So let's say that 5050 isn't stable at 1.25V, with a CO of +5 maybe the voltage is 1.275V and then the core is stable again.
most of us dont have custom loop cooling please do one w the regular 360/ 420 aio cooler please. So unfriendly.
SkatterBencher I have a question, for the past few days I have been attempting all iterations of your overlocking on my 7950X3D on a B650 AORUS Elite Motherboard. I have compared and contrasted multiple videos from yourself in which you either use my CPU or my Motherboard. I swear I am doing the correct things but I can seem to get a better average GHz than around 4.7 - If you have an idea for what I could be doing wrong I would greatly appreciate the help.
-40 negative offset ? i should it was hard limited to 30.
On Zen 4, negative curve optimizer goes to -300. Positive curve optimizer is still up to +30 (at least when I last checked when the chips launched)
@@SkatterBencher ah ok nice :) thank you !
well i go t a shitty one (agaaain) my one isnt booting at all after changing anything...
Great video! QQ: Why do you recommend these very specific CO negative offsets? I thought every CPU would be different, would love a similar guide for the 7800x3d when launched!
You're right that every CPU has different optimal CO negative offsets. I try my best to highlight in the video that one shouldn't 1:1 copy the settings and apply to their system, but it's not easy. I decide to still show the settings because it may help people feel more comfortable using those tools
I see in your segment for strategy #2 for Curve Optimizer, you have 25 shown as a selection for core 7, but then state it should be 35. Pointing this out to get clarification so others know. Thanks for these informative videos btw. I am trying to get mine to do strat #2, but it BSODs :( (all BIOS settings cleared b4 and followed as dictated)
Edit: can you do a video on how to oc using strat #2 curve optimizer for individualized silicon? ty
Oops, thanks for letting me know. I will pay more attention to the curve optimizer settings for next videos.
I've long had it on my backlog to make a video on how to do manual curve optimizer testing. Just haven't gotten around to do it ... :(
@@SkatterBencher Thanks for your amazing work and quick reply! I'm trying to glean more info to try and attempt this myself using your videos.
The values he puts in mean absolutely nothing because they're for his CPU, you need to use the values for your CPU....

I feel an aggressive undervolt would actually bring up those frequencies much higher while reducing temperatures and increasing performance without the need to overclock and increase power
Isnt OC Strategy 2 just that?
New CPU Drops... I immediately go to SkatterBencher and der8auer!

Thanks! I am going to try to find the best setup for gaming. I have Asus o x3D gaming settings on. But want to figure out what's best.
Star Citizen loads first on CCD1 and switches to CCD0 when ingame.
The game is limited by the rendering thread, and to get the best performance I think it need to run that on the fastest core, don't know how much cache it needs.
Overall I have only seen about max 35w usage.
I know a little here and there, but need to get my brain to rap around hwmonitor, look at performance.
I used Asus windows and did a setting there that really screwed me over. A bios reset didnt even help.
Exbo 1 suddenly also didn't work, so using number 2, but could not see any difference in settings applied. 6GHz C30 Corsair hynix.
I should have gone for an Intel setup since I need a better 1 core performance. But that ahip is sailed now.
I upgraded from a Ryzen 1600x!
please consider adding benchmarks for msfs and dcs. in the past, the 5800x3d showed remarkable gains for these titles. the 7950 x3d offers an interesting option. you could disable the v-cache ccd or the plain ccd. thus you have controlled for all other variables(memory, voltages, power supply, etc) to see the impact of cache alone
Thanks for the suggestion. Are there any standardized or built-in benchmarks for MSFS/DCS?

Why some cores (0 - 7) has boost about 5.2GHz only (in my case)? Is it possible to setup all to work at 5.7?
I can kind of answer this, but I need to know of you watched the whole video first
Amazing
I still like to watch people over clock cpu to showcase how much headroom it has . To some extent it mean reliable. But oc cpu dont really give much performance has it used to.
Wdym? Like the pro OC Competitors ? Or the common person?
You can overclock Ryzen 9 7950X3D with MSI MEG X670E GODLIKE or just ROG Crosshair X670E Extreme.
MSI MEG X670E GODLIKE has its VRM 24 phases.
You can do it on all 670 boards
What test software did you use to determine the per-core negative offsets? I could just use yours, but you say (understandably) that they may not be the best for my particular CPU.
I'm currently running -30 offset on all cores, but I'd like to experiment with per-core offsets.
The test software will vary depending on the architecture and even sample. When we use Curve Optimizer to undervolt, we need to find the weakest link for our CPU. Sometimes that's all core heavy AVX, sometimes it's single core SSE, and sometimes it's even idling at desktop.
I'll typically try first exploring with OCCT where I can define test scenarios for SSE, AVX, AVX2, and AVX512 for both all core and per-core. In the initial Curve Optimization process, I also use dynamic benchmarks like AI Benchmark, Geekbench, or the Y-Cruncher stress test to see if anything triggers instability after undervolt.
First thx for the great and detail explainantion, with your help I am starting to be able to OC my firt AMD CPU , What is your setting for the 2 minutes test with Corecycle ?
Y-Cruncher 00-x86 to check high boost and then also Y-Cruncher 19-ZN2 to check high load (AVX2 is usually the main struggle for me)
Wish I could post screenshots of gaming data here.
Why?
An interesting experiment, if possible, would be restricting CCD1 to the same 1.2V and seeing how the maximum frequency compares to CCD0.
I'm guessing that FMAX limit on CCD0 is due to the v-cache timing achievable at the voltage limit? (And that voltage limit set to protect against damage)
Awesome channel BTW!
For video editing in apps like adobe premiere , after effects and DaVinci Resolve which CPU is the best for performance? I9 13900K , 13900KS or AMD 7950X or AMD 7950X3D?
I just upgraded my i9 7980xe seven-year-old to 9 7950x3d. I got around 20 to 30% improvement. I appreciate seeing Ryzen running with a fraction of the power, but that was completely disappointing.
Precision boost overdrive 😂 drives Ryzen to much lower than what was mentioned in AMD marketing documentation. I hope I am missing something and come back and change this feedback. Meanwhile, I see tons of marketing from AMD and much less performance. It is Intel going behind that made the opportunity for AMD.
Now, speaking pure business, AMD is doing the correct thing, as energy consumption is the key, knowing that the world is going mobile. Desktops are secondary, and for gaming, they are being eaten by consoles. AMD looks stable and robust, and this makes it a winner l. BUT, a real jump in performance is an unmet wish.
I just gone with i9 13900k and 4090 gaming oc asus ^^ im not specific fan, but i think 7950x3d should be better instead of having low 1% fps and probolems with 2 ccd's, this time intel ^^ last time got gaming notebook with ryzen :D
7800X3D est le seul CPU en 7000 digne de l oc vue que un seul CCX activer donc pas de problème avec Windows et l oc apportera surement un meilleur FPS Merci de tester ce 7800X3D a sa sortie et contrairement au 7900X3D et 7950X3D qui ont du 3DV cache uniquement sur un CCX ses 2 CPU auront bcp de problème avec la gestion Windows ainsi que les jeux il aurai été plus judicieux de mettre du 3DV Cache dans les 2 CCX pour avoir un gap bien meilleur mais un gros problème existe sur le détail donner par AMD le 7800X3D n a un boost max de 5.0 GHZ et pas d oc manuel donc ses 2 grand frères équipé de 2 CCX un avec 3DV cache quel vitesse a celui ci ??? vue que l autre CCX va a 5.6 GHZ au 7900X3D et 5.7 GHZ 7950X3D la partie 3DV Cache limitant exactement comme le 5800X3D ,sur ses nouveau 7000 le risque est que Windows pilote la fréquence max du CCX sans 3dvcache alors quel GAP en FPS a espérer
Merci pour vos tests , amicalement 👍
no. asrock steel legend x670e won't let me go past -30 at per core mode . max is at -30.
I hope other vendors will do something like asus. (since i have an msi board lol)
So ECLK doesn’t affect other devices like USB and SATA, meaning it’s safe for daily use?
Also, the theoretical maximum speeds you can get sound like 6250 (non3D) / 5500 (3D) using PBO + ECLK. is that right?
Reference clock tuning doesn't affect anything except for the CPU clocks, but only if you're in ECLK1 mode. It's indeed safe for daily use.
If you're overclocking the reference clock in ICLK (internal clock) or ECLK0 mode, then it will affect those parts.
Theoretical maximum speed would be higher since ECLK can go pretty high. I achieved 170 MHz on water cooling at launch valid.x86.fr/ilmj1v. Let's say you stick to 110 MHz ECLK and a 200 MHz Fmax boost override, then the 7950X3D frequency would be 5775 (3D) / 6545 (non-3D).
@@SkatterBencher thank you! I misunderstood and thought the ECLK limit was 105.

@@SkatterBencher thank you so much. I really appreciate the thought alone! I just wanted to know if you followed the method of most undervolt on worst cores and least undervolt on best cores as well as see how to adjust your curve to mine
I don't really pay much attention to SP when it comes to final tuning of the chip. SP tells you about the P0 VID, but it doesn't tell you about the overclocking capability. I've seen "weak SP" cores overclock much better than "strong SP" cores.
So, when it comes to chip-specific tuning ... I just try all of them and see where I end up.

@@SkatterBencher I’ll be waiting for! I just got a 7900x3d and I don’t understand none of this stuff 😅
If you disable the non 3d ccd, how high can you get the 3d cores?
Not much higher than when the non-3D CCD is enabled. The highest I've seen is 5.5G+ but it was obviously not very stable.
The 3D V-Cache is tricky to overclock :)
@@SkatterBencher I'm seeing the same behavior now that mine came in. Some notes from my setup/testing thus far.
Asus ROG Strix X670e-i seems to be missing the eCLK setting in the bios.
Enabling the memory learning setting like we did with the 7600x for faster boot times led to some very poor memory stability.
My temps hit 90° rather quickly on this chip with the thermalright pressure plate. I may try the stock bracket to see if that helps, but did you hit 90° while benchmarking?
Hey SkatyerBencher, can you please let me know if you are getting Q code 8F with recent Bios and 7950X3D? I have this Q code which I have no idea what it means. Everything works and boots up perfectly though.
Did you have a look on the new curve shaper settings. It‘s already available on the Gene. Will it change the methodology or be an addition to it?
Curve shaper is the only thing I've been playing with for the past two weeks. I think it fundamentally changes the advanced overclocking strategies for Ryzen CPUs. However, I haven't yet come up with a good methodology how to use it in practice. Will feature for sure in future videos!
@@SkatterBencher Awesome can‘t wait!!!
I tried the 2nd strategy using your PBO curve optimization settings. I got similar benchmark scores (37,224 in Cinebench R23) but started seeing random crashes, especially when gaming. Hopefully one of the other methods works better with my silicon.
Did you copy the same curve optimizer values? If yes, please don't :).
Every CPU is different so the Curve Optimizer values will be different too. The only way to finetune using Curve Optimizer is by check the stability for each core.

Same situation. I suppose its pretty similar for us as it is for 7950
Thanks for the guide!
I didn't understand the 2 step at 31:16 . By that time we have positive all-core CO but the first bullet says "increase per-core NEGATIVE" CO. And next bullet again increases values but of positive CO.
Shouldn't we use positive at every step in ECLK process? Shouldn't it read as follows?
- increase all-core positive CO until unstable
- if unstable decrease per-core positive CO
Hi! I looked back at it and it's indeed a bit confusing. The idea here is that in step 1 we identify the frequency limit across all-core and in step 2 we're trying to do it for each core. We assume that in step 1 we'd be too conservative with the best cores, therefore in step 2 we try to reduce the curve optimizer. This will make it boost higher. However, for cores that remain unstable, we need to further increase the curve optimizer.
Hope this makes it a little more clear.
Can i overclock/boost 7950x3d cpu by 140 us dollar motherboard
Please Reply sir
Does anyone know if the V cache CCD on the 7900x3d has the same fixed freq cap (5250) as shown here for the 7950x3d? Since it has fewer active cores I was wondering if it might have a slightly higher fixed cap, which might be a good trade off if you don't regularly need all the additional cores of the 7950 for productivity.
It has a lower cap, AMD's website says 5000. I imagine you might be able to push it higher than the 7950x3d with good ECLK tuning, but I also think the better binned chips are going into the 7950x3d so it's probably less likely you'll get a chip you can really push that hard.
The thing that I haven't figured out is how you test the strength of each individual core so you can fine tune at a core level. Is it just trial and error?
Yes, per core tuning is trial and error
Can't you manual oc the CPU with the asynchronous bclk Mode? Just set the multiplier to whatever you can set it to (for example 50) and tune the Bclk with asynchronous mode (for example 110mhz). Thats then 5500mhz allcore.
Vcore 1,2v should be enough for that 🤔
Manual oc is not available on those chips (thus you cannot set the multiplier)
@@thecolossus_5917 but you can set the Bclk with asynchronous mode to like 140mhz.
On locked Intel chips you can still set the multiplier, but not higher than the boost clock of the chip. Isn't it the same here? Even if you can only set the baseclock multiplier of 40 you still could do around 5,6ghz allcore (140mhz bclk)

Hello It was a very instructive post. I am collecting systems after a long break. And I have been away from most technology and I have been using the z270 intel platform for 6 years, so I have a question, my system parts will be completed in a few days. I'm waiting for 7950x3D and my motherboard is Asus x670e hero. There was an issue that stuck in my mind, my memories are 4 sticks 16-16-16-16. I bought 2 dual channels. Gskill F5-6000J3038F16XS-TZ5NR. It's expo approved and it's on the motherboard's list, but I'm wondering if 4 sticks will cause problems.

There's a measurable difference both in benchmarks and real-world scenarios, like gaming. The difference between say, 6000 CL40 and 6000 CL30 is pretty substantial (assuming sub-timings are equal). Whether or not it would qualify as being "huge improvements" is kind of subjective, but there's certainly a noticeable difference.
Could this easily be applied to a 7900x3D or would your 7900x OC video be more relevant?
For the 7900X3D, this video is more relevant because it will have similar limitations with the V-Cache CCD
@@SkatterBencher Appreciate the reply. Great videos thanks.
I thought this doesn't release until Feb 28/tomorrow.
Twitter leaks suggested that Reviews will be on the 27th, and here we are.
It came out before this for RUclipsrs and such. But can't release any info until this date.
Do the worse cores on the X3D CCD need the higher positive CO value to operate stable with ECLK attempt? So i can check the hierarchy of the cores and go from there?
In my experience, the CPU core overclocking capability does not differ between X3D and non-X3D CCDs. It's just that they're limited by the V-Cache in frequency and temperature.
I speak english .. but I can't undertand a sentence this guy is trying to project.
