*Unfortunately this doesnt apply with Ryzen 3000, some 7000 chips* as they only support PBO1 (not PBO2) - Apologies for this, there will be a future BIOS guide for these chips in the future Ryzen 5000 should work perfectly fine! - FOR THOSE ON RYZEN 2,3,7000 chips, you can manually undervolt with this guide: ruclips.net/video/ONVrby6v_ts/видео.html&t
Good stuff. Its a great tool that needs highlighted. not sure if you've done this - Ryzen Master can find the CO figures per core via the optimiser . once its does just apply them to a profile withj your overclock. be awre it takles 50 mins for a 5600.
I followed the steps in this video for determining the stable undervolt, and then tested with OCCT to ensure stability. My 5800X3D managed a -25 all core, really stable undevolt. I noticed that -20 to a -25 had a small difference in performance gains, and the stable boost clock was only increased by 10-30 MHz, BUT with lower overall temperature and power consumption, and by extension holding the same clock more stable. With the latest BIOS update having the latest AGESA, I changed the setting of the curve optimizer permanently. The result: It is WAY more efficient in normal operation, and IT BOOSTS LIKE CRAZY when required. I noticed previously while gaming that it BARELY reached to 4.1 to 4.2 GHz on stock, and was a spiky boost. Now, after the undervolt, it reaches 4.4 to 4.5 GHz depending on the situation, and holds stable at that with ease, occasionally spiking to 4.6 GHz, all the while with lower temperatures. I encourage you to try it. Even if you are unlucky, a -10 easily yields a significant difference in stable boost, it stabilized at around 4.3GHz in full load in my tests. I have a 4090 on my system, and undervolting really made a difference, as it feels like the little CPU bottleneck that existed is now gone! A 5800X3D with an undervolt and an AIO cooler ROCKS. A couple complimentary things that can make your experience with this CPU even better, especially with a GPU like a 4080 or 4090: - Couple it with decent RAM on XMP, although nothing too fancy is required. Surprisingly, RAM on XMP at 3200 CL16 is enough to unleash this CPU, you don't really see any difference with anything better than this. Having DUAL RANK RAM sticks (google it if you don't know, it has nothing to do with dual channel), however, does have a significant positive impact, at some cases at least. - Set your games (and any other heavy processes you need to perform) on High Priority through process/task manager on windows. I am surprised at how few people do this, it really makes a difference on any CPU. Ryzen chips may need it even more than the latest intel chips, since the intel ones have efficiency cores that undertake background tasks. As such, it falls to the user to nudge the OS to the right direction.
wait so is doing it in the BIOS the same? cuz I went into PBO in my BIOS and saw the core voltage setting, so I set it to “All Cores/OFFSET:Negative/-30” is this essentially the same as using PBO2? I lve been running it for the past 2 weeks and haven’t had a crash, have much lower temps, and do see the card boost to 4.2-4.4mhz occasionally depends on the game if it stays there. I notice in Cyberpunk it doesn’t always stay boosted, is that normal?
PBO2 is the same as BIOS and Ryzen Master, the difference is that every time you restart your pc it will go back to the default. PBO2 is good for testing but once you get a stable offset for each core, using Ryzen master or BIOS will make that every time you startup or restart your pc, the values you have registered remain applied.@@_N4VE_
I think it's better advice to include corecycler as part of your stress testing. It's really good for telling you which cores are causing instability, allowing you to undervolt other cores further.
This; Cinebench is not good enough to use as a stress test; yeah it will find it and crash to give you a ball park, but CoreCycler is the BEST I would love if it was scripted to lower the voltage more on passing cores the same way it increases on a failed core
@@kokumosu being honest tho i use cinebench r23 mostly... yet to have a single crash in any workload or game... web browsing and so on... if you can pass r23 10 minute test then you're pretty much stable.
@@TheBURBAN111 I agree, after a stable 10 minute Cinebench run, I tortured my system with OCCT and everything was fine. In MOST cases, cinebench 10 min appears to be a good indicator. Also, corecycler is good, but OCCT is better in my opinion, as you can do more "variable" stress tests in order to be more certain.
Agreed. I prefer to avoid system crashes whenever possible :) Corecycler is great for single core hot/high load testing. I also use ycruncher for light load testing as described by this guy: ruclips.net/video/Qj2FO5qRp40/видео.html I use CBR23 for multicore and cpuz for single and multicore benchmark. The CBR23 single core test just takes waaaay too long for when you're working through the variables. This guy has one of the best undervolting tutorials imo: ruclips.net/video/dU5qLJqTSAc/видео.html
I did this like 6 months ago after watching a video by fr33thy. In his video he had you copy pbo2 tuner, name it pbo2 tuner 2, add it to the start up apps and after setting each core to -xx you don’t have to do it every time you power on your pc. I’d rather not need to open it and plug in the numbers every time I power on my pc. Thanks for the video as always!
ryzen masters auto curve optimiser seems pretty good too. previously I had set it to -15 on all cores in the bios and couldn't be bothered to do single core tuning. I used ryzen masters auto thing and it got me to -20 to -26 on 5 cores and -18 on one. Saved a hell of a lot of time, just hoping it is stable as I only did it last night
I pushed it to -25 but the clocks were a too stable, you want the cpu to still fluctuate but not a crazy amount. if not then it will cause frame skipping & in consistency. -23 seems to do the trick along with my bios configuration. I can share my settings if you would like
Yeah the "per core" auto optimizer is great IMO. With all core optimization I could only get -13 but per core some cores can do -27, but some only -5 still yielding a much more stable boost clock.
I used Ryzen Master as well and I'm happy! In terms of stability, I had some issues only once, so I went in and raised the level of my lowest core by 1 and it took care of it. I test by making a run through the least optimized areas in Star Citizen. That's the best real-world torture test I've found. I'm running a 5800X with a Scythe Fuma 2 air cooler and before undervolting I would hit 90* in those areas. After undervolt, I run solidly at 83* (thermal throttle is 85) and very steady at 4.8-4.9 GHz.
Okay... soo this isn't exactly "undervolting". AMD calls it "Curve Optimizer" and it basically tells the CPU that he can boost the frequency higher for the same amount of voltage compared to stock settings. You could truly undervolt if you use Ryzen Master or in the BIOS PBO2, where it allows you to adjust not only the PPT (Package Power Tracking) which is basically all the power in Watts that the CPU will pull and this can be reduced to do the same work with less energy thus making the CPU run a lot cooler. TDC (Thermal Design Current) basically the estable current (Amps) that the CPU will have available for the "undervolt" you saw in the video. EDC (Electrical Design Current) this will be the value (Amps) that the CPU will have, in charge of the frequency for when the cores boost. You can also undervolt manually in the bios but you will be setting a fixed value for core voltage whether its idling or boosting but doesn't perform as well as PBO2 does, as the chip doesn't stretch it legs as its meant to. For anyone that finds it useful in the future my 5800x PBO2+CO has a CO -30 all. PPT 130W. TDC 85A. EDC 110A. Air Cooler : Artic Freezer 34 eSports duo. Ambient temp 24ºC. At stock settings clock frequency 4850Mhz single core, 4550 multi core, max temp 89-91ºC stress test after 20 minutes. Gaming temps 70-75ºC. Idling temps 48-55ºC. With PBO2+CO settings got me same single core clock 4850Mhz. 4750 Mhz multicore, max temp 74ºC. Gaming temps low 50ºC during gaming, 60ºC spike when loading. Idling temps 30-35ºC. Had a +50mhz single core boost but would keep my gaming temps at 60-65ºC with 0 gains anywhere else. Had an stable 5050Mhz OC no CO, but constantly running at +80ºC while gaming with minimum performance gains. Lowering CO to -20 to increase frequency increases temps, not an option for me, I am a sucker for efficiency.
Nice guide, im running -20 on my 5700x, it gave me 800 extra points in cinebench and lower temperatures. Power usage its the same since its already a eco chip. But going from 3899 mhz under stress test to 4049 its okay for me. Its been stable with cinebench for 10 min and gaming 30 min
Something wrong with your 5700x, I have a 5800x with Curve optimizer at -30, stock clocks and undervolted, running at 4850 mhz single and 4750/35 all cores under stress. I have been stable for months now. Best I can do in overclock is +50mhz, anything above it I need to dial back the CO to -20 or it crashes in games.
@@mrsuperselenio5694 When im searching for 5800x cinebench r23 there is a lot running around 4000 mhz in multi thread test. Maybe im mistaken, but mine boost to 4650 mhz at light load, and 4049 when under 100% load
Thanks for the video. One thing I learned, was that you should run a stress test and keep a close eye on HWinfo and specially on CORE EFFECTIVE CLOCKS. Some cores might crash or stuck on much lower clocks, because all cores are not equal. So I almost guarantee, that you have to raise some core's level separately. Your machine might not crash, but it surely runs worse, as you would imagine. I learned this on SkatterBencher's "AMD Precision Boost Overdrive 2 & Curve Optimizer Explored | SB#24"-video. Very, VERY good info!
OUTSTANDING!!! Just applied this and got to -30 on the PBO on my 5600x3d on a tomahawk b450 regular and wow huge difference. -12 degrees to the package temps and boosts sustained at 4400 pegging 4450 occasionally with an assassin stealth air cooler. Core voltage dropped from 1.29 to 1.20, temps from 85 to 73, and cores from load max of 4025 to max of 4350 and two cores pegging 4450.
@@geekyb0175 who cares though? cpu undervolting is very safe, and if it crashes, they can just simply increase the voltage. you can't exactly harm a cpu in any way by not giving it ENOUGH power, but you can by giving it TOO much. id say if they see performance gains, they should let it run as fast as possible. if there's any instability, it isn't hard to fix.
Good stuff, I run my 5800x3d at -30 all cores and get it to apply it when the PC boots. I even use this with my 5600 and 5800x CPUs as easier than rebooting to change bios each time. I can recommend CoreCycler to test your CPU. I find this is really good at finding the cores with errors, and then you can back off individual cores. You need to edit an ini file to make it work but it is quite easy and it lets you pick the cores to test, duration, exclude cores when they error etc. When all seems stable I run this over night just to me double sure.
On MSI MOBO just use the Curve Optimizer from: Overclocking\Advanced CPU Configuration\AMD Overclocking\Curve Optimizer. Other MOBOs may have similar menu, just look for it. Make sure to DISABLE the PBO Limits. Then in Curve Optimizer change to ALL CORES, the SIGN to NEGATIVE and start with 30 and if not stable start lowering towards the 25. I started with 25 and was good, changed it to 30 and Windows crashed, changed to 28, good so far. What you get by using the Curve Optimizer is lower CPU Voltage (better for CPU), lower maximum W so lower TDP, lower maximum temperature under load, more clock speed. Only thing is that my 5600X is not going faster than 4649MHz even though it is cooler, thus less throttling.
@@11bravo1789 you still need to install PBO2. I used to use the BIOS to -30 all cores but ended up resetting my BIOS to default and just use PBO2. I noticed the boost clocks are more frequent when using PBO2 for some reason.
For everyone confused in the comments, just go find another video about this. I wouldn't say this is very helpful if everyone that watches is still basically clueless at the end of the video. Setting it up in windows scheduler so the undervolt applies every time you start your pc is a huge quality of life improvement as well.
FINALLY! A very simple and effective way to control the temp of my Ryzen 9 5900X. This thing was running 85-90 degree's every time I fired up a game. (iRacing, ACC, Way of the Hunter) It didn't matter what program or app I used, the temp would not come down. What did the trick tho really wasn't the instructions here but the "limits" tab in this program. Being able to actually set a temp limit is a God send. The out of the box speed for a Ryzen 9 5900X is 3.7. For me the curve limit was -30 but I run it at -25. I then set the limits to MaxBoost 4.3 with a temp limit of 65 degree's. I could push it more but I don't want to. Your mileage may vary. PS: I used the AMD Adrenalin software to monitor the temp and speed instead of CPUID during testing. I figured out how to start it at startup too! Follow link, starting at 5:56 in. ruclips.net/video/-l30dYv4KOo/видео.html
Thank you! I have tested in some games and in Cinebench. -30 offset. Since, it was GPU bottleneck, the FPS was the same, however power usage dropped down from 70-72W to 55-60, and lowering temps from 77 to 67 celsious. In the Cinebench I wsa getting the same temps, however the score got higher (+800pts I think) and the frequences rised from 3.8 to 4.3GHz on R5 5600 & B450, Stock Wraith Stealth cooler.
Nice video! I played around with AMD System Setting (maybe it has another name in your Efi) and tried the 45 Watt setting (instead 65 Watt). I was surprised that i lost only 7 percent in cinebench but temps went down dramatically. Maybe a good idea for Office Ryzen PCs.....
My 5600 does -30 without issue. Massive power savings and better performance for longer. Note that if your goal is purely to maximize clock speeds over time the max possible value isn't always the best. My chip sustains max boost longest at -20, for instance. But I only do bursty workloads, so I don't need to hold those clocks for long. Hence -30.
@@basketballeverything6796 If your temps are high absolutely leave it at -30 to keep them as low as possible. Going back up to -25 would just make it hotter by adding more voltage. You'd end up with less performance for no real benefit, most likely. Hope this helps.
I try -30 without any issues on my 5 5600 too, my psu is a 500w corsair one, and i had a 2060 paired with them, my temps drops 15 degrees in new world, from 75 c to 59 c, the only problem is set -30 on the program every time i open them
@@starlite3597Possibly a setting in “Advanced Tuning” called PBO where you’ll find “Core Voltage”. Then set to “All Cores/Offset:Negative/-30” or whatever you want to try. If you’re worried about crashing try starting at -20 or -25
I use the program today. PBO2 Tuner. Follow your steps and I get my CPU (Ryzen 7 5700X3D) to - 50 maximum undervolt. This setting passed the 10 min throttling test. From stock temps 73.5°C to 66.4°C and from 101.47Watts to 84.94Watts. CPU up to 4149 MHz. And a score 13663 in Cinebench R23.
This has certainly made things much better for me after installing a BIOS update specifying "Enhanced performance for 5800X3D". All it did was run hotter and louder, and not any faster. I had set -20 in the BIOS which helped, but couldn't go any lower using the BIOS settings. This software is letting me run at -35, making things much more bearable but still not quite as quiet and efficient as the older BIOS. Runnig a 5800X3D on an Aorus B550m Elite, cooled by an Arctic Liquid Freezer II 240 on two of their new P12 Max fans and MX-6 paste.
@@zeebm_ I think he might be confused because the PBO Tuner software lets you enter any value and it will say: "Applying curve: -35|-35|-35|-35|-35|-35|-35|-35", and the numbers change in the software but if you close it and open it again you'll see it's all back to -30 because as you say -30 is the lowest point for the 5000 series.
@@gunnarthegumbootguy7909 As I understand, e lowered -20 in the bios and -15 more on PBO2. I do something similar. I have -20 at bios all the time and when I want to play I add -10 on PBO2. Over -20 at my bios wasn't stable when idling. It crushed a few times. Doing that I have 4.3mhz on all cores 4.5 on single threads peaks when I am on the browser and 4.45 on all cores with 4.55-4.6 peaks when I play Far Cry 5 on 60C
What got me the most temp drops but maintaining same score points in cinebench was disabling turbo completely and run it at a fixed speed. I run mine at 4.4ghz with a slight undervolt (i'm not sure how much). I have a small case so temps are important (NR200P MAX). 5900X: Stock temps: under load instant 85c PBO (similar testing like your video): NOT instantly 85c but gradually, PBO tries to maintain boost clock until the temp won't let it anymore and will eventually downclock to stock core speed 3.8 (in my situation) With fixed clock speeds and undervolt: i barely hit 80c, usually hovers at 78c which is more comfortable with me as the heat of my strix 3080 also passes through.
since i moved from console to PC you are the man i look for for new tips and ticks to squeeze every bit of performance from my pc. thanks for your hard work man. I just got a new 5900x and i love to tinker. my question is it better to do a all core OC or enable PBO for gaming?
i just undervolted my r7 5800h with -50, score on cinebench went dramatically higher than I expected, temps are great, don't exceed 95C and clock speeds are also higher, above that, 0 craches i'm happy ;]
So I watched your video, tried it and I was surprised that my CPU was stable at -50. The difference in terms of temperature is a 5%, still good since I live at Philippines so it's hot. Did the 10 minutes test and yup, stable at -50
I'm building an ITX system here is my current results: 5600G in an ASRock B550M-ITX/ac motherboard CPU PBO: -15 -25 -25 -15 -25 -15 GFX PBO: -30 2x16GB Crucial Ballistix 3000 at 3333MHz 16-18-16-16-34 timings and 1.27V (I managed to reach 3933Mhz CL18 but the extra voltage and heat doesn't worth it for me) SoC: 1.115 -> 0.918V NorthBridge: 1.050 -> 0.990V here are the power consumption data from the wall, software readings are useless all over the place idle: 21W Aida64 CPU: 63W -> 56W Aida64 FPU: 93W -> 86W Heaven benchmark 53W ->49W PBO was hard set, because the CPU is heat sensitive, 1 core benchmarks will not show if the undervolt is stable, I could push some cores to -30 PBO if the temps are under 60°C, but fails over 65°C. The fastest stability test is heat up the CPU in Aida64, then run the memory and latency test, if the system not stable it reboots instantly. Originally I wanted 5300G but the 5600G is cheaper to get so maybe I will disable 2 cores if it gets too hot in a tiny case.
I see you are running a MSI motherboard have you tried Kombo Strike i have and scored a 14000 on cinebench r23 on a 10 minute test.Just asking.With my R7 5800X3D.
Great video but what you wrote underneath it is confusing. I have a Ryzen 7 3800X , so are you saying this program WON'T work on it ? Am I correctly understanding you ? Thanks.
Personally I use OCCT per thread torture test for my testing. makes it to where i can test each core specifically for instability and make sure is a large data set.
Panj, i was just able to undervolt -50. i know that's not typical. temps down 12degrees frames up 10avg, it's stabil. what does such a high overvolt mean?!
I have a Ryzen 5600X... It already pass -45... And good. I'll try -50 to see if cinebench or my PC crashes... But why that much difference? You're doing it on a better cpu (Ryzen 7 5800x). -45 stable and 10.962 points EDIT: stable with -50 and 10978 points. The software didn't let me go over 50 (at -55 warning: out of safe range -55). Is the software bad? Am I doing something wrong? edit 2: ran a 10 minutes cinebench test at -50 and 10.950 point, it completed good... max package power 78.01W, max temp 53.0 °C max voltage 1.225V and max cores at 4600MHz (one 4592 others 4607). I will run a OCCT stress now but is it weird to get a totally stable system with -50 undervolt?
I can run CB23 for hours at -30, but it doesn't mean that system is stable. Idk how good is OCCT, but Prime95 will show you real picture for sure. In my case lowest i could go is between minus 15-18.
Ahhh help?! I'm currently at -50 and its still pushing. But score from -30(13,457) using cinebench and now currently -50(13,366); the drop off starter around -40(13,396) Pbo tuner is warning me around -60, that i'm beyond safe threshold Currently doing 10min for -50, its still going. 1 min left in. -Should i push further? -what are the pros n cons for pushing past -60? Should I just go back to -30 and call it quits?
I used the under volt in the bios, very easy, applied a -30 under volt. Depends on the Chip but please try it. The chip will run faster and cooler. Win win. Each core ran at 200mhz faster and cinebench scored an extra 500 points.
same here, found the BIOS setting for core voltage and just set a negative offset of -30 on all cores. So far it’s been stable during long gaming sessions on my off days. Temps never hit the 70s anymore unless the cpu runs a heavy load during processing like when I run Dyndolod for Skyrim modding. Although last night I did notice sometimes in Baldurs Gate 3 i’d get a short hitch after saving the game or opening the pause menu. So I might go to -25 if it keeps happening. Never had a crash tho in any game
Nice tool! You can adjust undervolt on a per core basis by looking at which core has crashed when undervolt is too low in Event viewer then only raise this core by 5, rinse and repeat
DONT DO THIS IF U PLAY VALORANT, I tried to do it and vanguard popped up saying that the program wasnt ok to use with vanguard installed, not worth getting banned for. Ur tweaks normally are great tho keep up the vids
Wrong. Using it for months, playing Valorant / CSGO Faceit etc daily. Not even one single problem since using it. TL:DR It's completely fine to use with any modern Anti-Cheat
fiddled with my bios and punched this numbers to my Ryzen 7 5700X.. cores 1-7 is at -26 and core 8 is at -24. boost Override CPU is at +200Mhz, PPT: 112 TDC: 75 EDC: 105. In R23 all core it can maintain 4.4Ghz at 73c with a score of 15,003 points highest (but the average i get is 14,860+) single core score 1,530. prime 95 large FFT's maximum temp is 80c 10 min run with no crashes and stable. cooler is be quiet dark rock pro 4 with custom high rpm fans.
I prefer using Prime95 with both AVX2 and SSE testing to get my CPU stable. I was stable in Cinebench with my worst (by undervolting) core with -12 setting, but Prime95 was almost immediately crashing on both corresponding workers. By reducing that core to -6 it became rock solid. Other cores were way better with -15 to -28 setting. And yes, you can fine tune it on per-core basis, it just requires more time.
The problem with all of these stability test is that these tests are not 100% trustworthy. I had crashes days later randomly. You have to see if it runs using your PC in the end. I used Ryzen master software with my 5900x till I got good values. Than added it to my bios settings. But it takes a long time and isn’t really worth the trouble in the end in my opinion.
Whats the difference of doing this operation with bios and with this way? Instead of starting pbo software everytime just tweaking via bios one time seems so much practical. Thank you for this video btw.
Im running a 7 5800x (non 3D) and somehow reached -50 without crashing?? Is the software out of date?? When it tried making it -55 it said "Out of safe range" and i couldnt make it lower than -50 Edit: Just did a 10 min test at -50 and yeah it didnt crash. And btw forgot to mention i got about 200 extra mhz Edit 2: My pc crashed while running GTAV, and even if i set the value to -45 it automatically makes it -30 when i exit the app.
I actually had to raise power modes to get my full boost speeds. In games I was seeing 18-32 watts now it’s 40-60. This is the 5800X3D it’s a little hotter now but not noticeable with my cooler. Temp’s average 40c
@@Shadow4ko hey man same but how do u save it , i used this app and then restarted and the values turned into 0 , well i used to pbo limit in my bios so do i do that ?
Save the undervolt values for each core in the BIOS. Ryzen Master has an automated utility that will test all your cores and recommend an undervolt for each core. Once you save it in BIOS you won't have to set it again until you do a firmware update (write them down somewhere). I undervolted my 5800X and brought my temps down to where I don't hit thermal throttle in the most demanding games I have and the CPU runs at full boost all the time.

Got a question. I just upgraded to a Ryzen 5 5500 and when I checked the BIOS for PBO, it was set to auto. Now, I did not change that setting and followed the instructions in this video. However, it seems that I'm not getting much of an increase, and even sometimes get less score on my Cinebench R23 results. I've reached an offset of -40 in my testing and the most I got out of my cores was around 4270+mhz, which was hovering the same amount with a -10 offset. So, should I turn PBO off in the BIOS before I do this again, or is this irrelevant and should work regardless if my PBO is set to auto? Would really appreciate it if you could reply. Thanks
great video mate i tried this with my 5950x & X570 board but my core clock speed stayed at 4099Mhz 155w and a temp of 50c i got PBO2 tuner down all the way to -50 and it was still stable but nothing appeared to be changing in HWMonitor. any advice on that?
ok is it normal that my computer performs best at -50 and doesnt crash? is that too far or is it ok to just simply go as low until it crashes, granted i havent tried a game yet only done using cinebench

CO instability shows up at the HIGHEST clocks, which is at the LOWEST load, and Corecycler is the best tool for both testing and diagnosis; it has tests that simulate very low loads and tells you WHICH core has failed.
-30 is the lowest you can set it to on any 5000 series cpu anyway, but for 5800x3d with a recent bios update -30 should be stable for every single 5800x3d out there. For everyone who has a 5800x3d, looking for bios updates is absolutely worth it, they've fixed a lot of stability and performance since it was released.

Usually floats in the 60s while gaming, occasionally hits 70s during heavy processes like when I run Dyndolod for Skyrim modding
5600X and MSI B550 tomahawk, I just set it to -15 and it has dropped the power and temps by 5-10% (roughly). I didnt do any further testing after -15. It's fine.
I noticed my 5900X is locked at 3.7Ghz on my Gigabyte X570 motherboard. I have to manually dial in the ratio and do an undervolt in the BIOS. This software did nothing for me. How do I switch this off in the BIOS?
PBO2Tuner says unsupported CPU model. I have a Ryzen 4600H. Sadly I haven't been able to find a software that helps me undervolt my CPU. It's been a hindrance when gaming for a while now.
The issue with using PBO2 tuner is that you have to set up a task on windows and do task scheduler that not always works. otherwise you have to do this every time you restart or start your system. you BIOS is easier.
@@Panjno lmao why are people so lazy i turn on my pc have 5800x3d it takes maybe 5 seconds i tab and put -25 on all of them boot up my game stream and discord and play lmao
The tool is for TESTING for stable UV without needing to go into BIOS everytime you crash. Once you figured a stable number only THEN lock it into the BIOS.
Im not able to go above my CPU base frequency during Cinebench multicore test. When not running the test with turbo boost enabled, ill get around 4.4ghz max. Why is this capped during stress test? My cpu: AMD Ryzen 7 5800H Radeon graphics. 3.2 base clock
How to know what chipset i'm using as my system model is 82JQ and i'm not getting the information about which chipset i have can you help me to know about it
I use HYDRA instead on PBO tuner. It starts with windows, so i don't have to think about it. I would use the bios thing, but HYDRA is better for performance. Meaning, my 5600(nonX) takes different values for each core( -22,-23,-30,-24,-24,-29) ,reached these values testing with OCCP each core separately. All fine and dandy, i could punch in these numbers in bios as well. However HYDRA has a setting where all these values go to -30 when CPU is working at over 70%(or whatever percentage you want). And tests pass with -30 all cores if cpu works hard, My cores are not stable at -30 if i do normal stuff like browsing or whatever meaningless tasks. It is stable when the processor works up a sweat though. Pretty interesting if i do say so... I tested this myself after i saw some people talking about it on some reddit page.
@@ispodstrehe3065 Well, numbers don't lie. Synthetic scores went up a bit, like 1000 in cinebench R23 for multicore. I haven't experienced microstutters even when the cpu was at stock. I do the undervolt thing pretty much because the temps are lower. So, performing better is just extra bonus.
*Unfortunately this doesnt apply with Ryzen 3000, some 7000 chips* as they only support PBO1 (not PBO2) - Apologies for this, there will be a future BIOS guide for these chips in the future
Ryzen 5000 should work perfectly fine! - FOR THOSE ON RYZEN 2,3,7000 chips, you can manually undervolt with this guide: ruclips.net/video/ONVrby6v_ts/видео.html&t
And 2000?
Could some of this tips apply for ryzen laptop users?
@@Heliols135 Use the guide linked above :)
I have Ryzen 5 5500 and it didn't worked. Resaults are same no matter what I apply
Good stuff. Its a great tool that needs highlighted. not sure if you've done this - Ryzen Master can find the CO figures per core via the optimiser . once its does just apply them to a profile withj your overclock. be awre it takles 50 mins for a 5600.
I followed the steps in this video for determining the stable undervolt, and then tested with OCCT to ensure stability. My 5800X3D managed a -25 all core, really stable undevolt. I noticed that -20 to a -25 had a small difference in performance gains, and the stable boost clock was only increased by 10-30 MHz, BUT with lower overall temperature and power consumption, and by extension holding the same clock more stable. With the latest BIOS update having the latest AGESA, I changed the setting of the curve optimizer permanently.
The result: It is WAY more efficient in normal operation, and IT BOOSTS LIKE CRAZY when required. I noticed previously while gaming that it BARELY reached to 4.1 to 4.2 GHz on stock, and was a spiky boost. Now, after the undervolt, it reaches 4.4 to 4.5 GHz depending on the situation, and holds stable at that with ease, occasionally spiking to 4.6 GHz, all the while with lower temperatures. I encourage you to try it. Even if you are unlucky, a -10 easily yields a significant difference in stable boost, it stabilized at around 4.3GHz in full load in my tests.
I have a 4090 on my system, and undervolting really made a difference, as it feels like the little CPU bottleneck that existed is now gone!
A 5800X3D with an undervolt and an AIO cooler ROCKS. A couple complimentary things that can make your experience with this CPU even better, especially with a GPU like a 4080 or 4090:
- Couple it with decent RAM on XMP, although nothing too fancy is required. Surprisingly, RAM on XMP at 3200 CL16 is enough to unleash this CPU, you don't really see any difference with anything better than this. Having DUAL RANK RAM sticks (google it if you don't know, it has nothing to do with dual channel), however, does have a significant positive impact, at some cases at least.
- Set your games (and any other heavy processes you need to perform) on High Priority through process/task manager on windows. I am surprised at how few people do this, it really makes a difference on any CPU. Ryzen chips may need it even more than the latest intel chips, since the intel ones have efficiency cores that undertake background tasks. As such, it falls to the user to nudge the OS to the right direction.
wait so is doing it in the BIOS the same? cuz I went into PBO in my BIOS and saw the core voltage setting, so I set it to “All Cores/OFFSET:Negative/-30” is this essentially the same as using PBO2? I lve been running it for the past 2 weeks and haven’t had a crash, have much lower temps, and do see the card boost to 4.2-4.4mhz occasionally depends on the game if it stays there. I notice in Cyberpunk it doesn’t always stay boosted, is that normal?
Thx alot ❤
PBO2 is the same as BIOS and Ryzen Master, the difference is that every time you restart your pc it will go back to the default. PBO2 is good for testing but once you get a stable offset for each core, using Ryzen master or BIOS will make that every time you startup or restart your pc, the values you have registered remain applied.@@_N4VE_
I think it's better advice to include corecycler as part of your stress testing. It's really good for telling you which cores are causing instability, allowing you to undervolt other cores further.
This; Cinebench is not good enough to use as a stress test; yeah it will find it and crash to give you a ball park, but CoreCycler is the BEST
I would love if it was scripted to lower the voltage more on passing cores the same way it increases on a failed core
@@kokumosu being honest tho i use cinebench r23 mostly... yet to have a single crash in any workload or game... web browsing and so on... if you can pass r23 10 minute test then you're pretty much stable.
@@TheBURBAN111 I agree, after a stable 10 minute Cinebench run, I tortured my system with OCCT and everything was fine. In MOST cases, cinebench 10 min appears to be a good indicator. Also, corecycler is good, but OCCT is better in my opinion, as you can do more "variable" stress tests in order to be more certain.
Agreed. I prefer to avoid system crashes whenever possible :)
Corecycler is great for single core hot/high load testing. I also use ycruncher for light load testing as described by this guy: ruclips.net/video/Qj2FO5qRp40/видео.html
I use CBR23 for multicore and cpuz for single and multicore benchmark. The CBR23 single core test just takes waaaay too long for when you're working through the variables.
This guy has one of the best undervolting tutorials imo: ruclips.net/video/dU5qLJqTSAc/видео.html
You can check the crash report in windows Event Viewer to know which one crashed.
Giving this a try on my 5700X.

I did this like 6 months ago after watching a video by fr33thy. In his video he had you copy pbo2 tuner, name it pbo2 tuner 2, add it to the start up apps and after setting each core to -xx you don’t have to do it every time you power on your pc. I’d rather not need to open it and plug in the numbers every time I power on my pc. Thanks for the video as always!
ryzen masters auto curve optimiser seems pretty good too. previously I had set it to -15 on all cores in the bios and couldn't be bothered to do single core tuning. I used ryzen masters auto thing and it got me to -20 to -26 on 5 cores and -18 on one. Saved a hell of a lot of time, just hoping it is stable as I only did it last night
Mine goes to -14 stable. That seems to be the sweet spot for me but I’m gonna keep fiddling around with pbo to see if I can push it more
I pushed it to -25 but the clocks were a too stable, you want the cpu to still fluctuate but not a crazy amount. if not then it will cause frame skipping & in consistency. -23 seems to do the trick along with my bios configuration.
I can share my settings if you would like
Yeah the "per core" auto optimizer is great IMO. With all core optimization I could only get -13 but per core some cores can do -27, but some only -5 still yielding a much more stable boost clock.
I used Ryzen Master as well and I'm happy! In terms of stability, I had some issues only once, so I went in and raised the level of my lowest core by 1 and it took care of it.
I test by making a run through the least optimized areas in Star Citizen. That's the best real-world torture test I've found. I'm running a 5800X with a Scythe Fuma 2 air cooler and before undervolting I would hit 90* in those areas. After undervolt, I run solidly at 83* (thermal throttle is 85) and very steady at 4.8-4.9 GHz.
@@Remu- mine went all the way to -29 all core. -30 was giving me system latency so I dropped it by an increment of 1 and it worked out.
Okay... soo this isn't exactly "undervolting". AMD calls it "Curve Optimizer" and it basically tells the CPU that he can boost the frequency higher for the same amount of voltage compared to stock settings. You could truly undervolt if you use Ryzen Master or in the BIOS PBO2, where it allows you to adjust not only the PPT (Package Power Tracking) which is basically all the power in Watts that the CPU will pull and this can be reduced to do the same work with less energy thus making the CPU run a lot cooler. TDC (Thermal Design Current) basically the estable current (Amps) that the CPU will have available for the "undervolt" you saw in the video. EDC (Electrical Design Current) this will be the value (Amps) that the CPU will have, in charge of the frequency for when the cores boost. You can also undervolt manually in the bios but you will be setting a fixed value for core voltage whether its idling or boosting but doesn't perform as well as PBO2 does, as the chip doesn't stretch it legs as its meant to.
For anyone that finds it useful in the future my 5800x PBO2+CO has a CO -30 all. PPT 130W. TDC 85A. EDC 110A. Air Cooler : Artic Freezer 34 eSports duo. Ambient temp 24ºC.
At stock settings clock frequency 4850Mhz single core, 4550 multi core, max temp 89-91ºC stress test after 20 minutes. Gaming temps 70-75ºC. Idling temps 48-55ºC.
With PBO2+CO settings got me same single core clock 4850Mhz. 4750 Mhz multicore, max temp 74ºC. Gaming temps low 50ºC during gaming, 60ºC spike when loading. Idling temps 30-35ºC. Had a +50mhz single core boost but would keep my gaming temps at 60-65ºC with 0 gains anywhere else. Had an stable 5050Mhz OC no CO, but constantly running at +80ºC while gaming with minimum performance gains. Lowering CO to -20 to increase frequency increases temps, not an option for me, I am a sucker for efficiency.
Nice guide, im running -20 on my 5700x, it gave me 800 extra points in cinebench and lower temperatures. Power usage its the same since its already a eco chip. But going from 3899 mhz under stress test to 4049 its okay for me. Its been stable with cinebench for 10 min and gaming 30 min
Something wrong with your 5700x, I have a 5800x with Curve optimizer at -30, stock clocks and undervolted, running at 4850 mhz single and 4750/35 all cores under stress. I have been stable for months now. Best I can do in overclock is +50mhz, anything above it I need to dial back the CO to -20 or it crashes in games.
@@mrsuperselenio5694 When im searching for 5800x cinebench r23 there is a lot running around 4000 mhz in multi thread test.
Maybe im mistaken, but mine boost to 4650 mhz at light load, and 4049 when under 100% load
Thanks for the video.
One thing I learned, was that you should run a stress test and keep a close eye on HWinfo and specially on CORE EFFECTIVE CLOCKS.
Some cores might crash or stuck on much lower clocks, because all cores are not equal. So I almost guarantee, that you have to raise some core's level separately.
Your machine might not crash, but it surely runs worse, as you would imagine.
I learned this on SkatterBencher's "AMD Precision Boost Overdrive 2 & Curve Optimizer Explored | SB#24"-video. Very, VERY good info!
Ryzen Master. Totally automatic testing tool to do a per core undervolt...
OUTSTANDING!!!
Just applied this and got to -30 on the PBO on my 5600x3d on a tomahawk b450 regular and wow huge difference.
-12 degrees to the package temps and boosts sustained at 4400 pegging 4450 occasionally with an assassin stealth air cooler.
Core voltage dropped from 1.29 to 1.20, temps from 85 to 73, and cores from load max of 4025 to max of 4350 and two cores pegging 4450.
Extremely bad setting. You see performance gains. I see unstable system.
@@geekyb0175 Gaming on it daily for the last 8 months its been rock solid for me.
@@geekyb0175 who cares though? cpu undervolting is very safe, and if it crashes, they can just simply increase the voltage. you can't exactly harm a cpu in any way by not giving it ENOUGH power, but you can by giving it TOO much. id say if they see performance gains, they should let it run as fast as possible. if there's any instability, it isn't hard to fix.
i just undervolted my Ryzen 5 5600x and i was able to do -50 on all cores and its stable on 10 min Cinebench r23. im abt to test games!
Good stuff, I run my 5800x3d at -30 all cores and get it to apply it when the PC boots. I even use this with my 5600 and 5800x CPUs as easier than rebooting to change bios each time.
I can recommend CoreCycler to test your CPU. I find this is really good at finding the cores with errors, and then you can back off individual cores. You need to edit an ini file to make it work but it is quite easy and it lets you pick the cores to test, duration, exclude cores when they error etc. When all seems stable I run this over night just to me double sure.
How do you set it to do the UV everytime PC boots.
On MSI MOBO just use the Curve Optimizer from: Overclocking\Advanced CPU Configuration\AMD Overclocking\Curve Optimizer.
Other MOBOs may have similar menu, just look for it. Make sure to DISABLE the PBO Limits. Then in Curve Optimizer change to ALL CORES, the SIGN to NEGATIVE and start with 30 and if not stable start lowering towards the 25.
I started with 25 and was good, changed it to 30 and Windows crashed, changed to 28, good so far.
What you get by using the Curve Optimizer is lower CPU Voltage (better for CPU), lower maximum W so lower TDP, lower maximum temperature under load, more clock speed.
Only thing is that my 5600X is not going faster than 4649MHz even though it is cooler, thus less throttling.
Just wanna let you know, thanks for expanding my Pc knowledge and more fps❤❤
and thank you for showing support
For the 5800X3D u just need to update your BIOS to get the latest AGESA version and setup PBO2 with -30 on all cores from the BIOS without a sweat :)
Yup. Run windows scheduler too
-30 in offset ur what? How many mV do i need to set it to?
So I am getting ready to install my 3800X3D. Is the PBO2 in the Bios already or Do I need to download that ? My MB is an AS rock B550M-C.
@@11bravo1789 you still need to install PBO2. I used to use the BIOS to -30 all cores but ended up resetting my BIOS to default and just use PBO2. I noticed the boost clocks are more frequent when using PBO2 for some reason.
For everyone confused in the comments, just go find another video about this. I wouldn't say this is very helpful if everyone that watches is still basically clueless at the end of the video. Setting it up in windows scheduler so the undervolt applies every time you start your pc is a huge quality of life improvement as well.
FINALLY! A very simple and effective way to control the temp of my Ryzen 9 5900X. This thing was running 85-90 degree's every time I fired up a game. (iRacing, ACC, Way of the Hunter) It didn't matter what program or app I used, the temp would not come down. What did the trick tho really wasn't the instructions here but the "limits" tab in this program. Being able to actually set a temp limit is a God send.
The out of the box speed for a Ryzen 9 5900X is 3.7. For me the curve limit was -30 but I run it at -25. I then set the limits to MaxBoost 4.3 with a temp limit of 65 degree's. I could push it more but I don't want to. Your mileage may vary.
PS: I used the AMD Adrenalin software to monitor the temp and speed instead of CPUID during testing. I figured out how to start it at startup too! Follow link, starting at 5:56 in. ruclips.net/video/-l30dYv4KOo/видео.html
Thank you!
I have tested in some games and in Cinebench. -30 offset.
Since, it was GPU bottleneck, the FPS was the same, however power usage dropped down from 70-72W to 55-60, and lowering temps from 77 to 67 celsious.
In the Cinebench I wsa getting the same temps, however the score got higher (+800pts I think) and the frequences rised from 3.8 to 4.3GHz on R5 5600 & B450, Stock Wraith Stealth cooler.
what was your undervolt settings?
@@Matt-bb3oz all the cores on -30, my friend.
I did this with Yuri Bubly's Project Hydra application. Results are great. Low power high performance no fps lose. My 5800X3D's curve all core -30
Nice video! I played around with AMD System Setting (maybe it has another name in your Efi) and tried the 45 Watt setting (instead 65 Watt). I was surprised that i lost only 7 percent in cinebench but temps went down dramatically. Maybe a good idea for Office Ryzen PCs.....
I got lucky, got it stable @ -30 and with around 5 to 7c cooler. Thank you for the video, this simplified alot.cheers
My 5600 does -30 without issue. Massive power savings and better performance for longer. Note that if your goal is purely to maximize clock speeds over time the max possible value isn't always the best.
My chip sustains max boost longest at -20, for instance. But I only do bursty workloads, so I don't need to hold those clocks for long. Hence -30.
i have a 5600 too and ever since i got it i have high temps curve optimizer set it to -30 but what would you recommend -20 -25 or -30?
@@basketballeverything6796 If your temps are high absolutely leave it at -30 to keep them as low as possible. Going back up to -25 would just make it hotter by adding more voltage.
You'd end up with less performance for no real benefit, most likely. Hope this helps.
how would i do undervolt in bios? i have 5600 thanks
I try -30 without any issues on my 5 5600 too, my psu is a 500w corsair one, and i had a 2060 paired with them, my temps drops 15 degrees in new world, from 75 c to 59 c, the only problem is set -30 on the program every time i open them
@@starlite3597Possibly a setting in “Advanced Tuning” called PBO where you’ll find “Core Voltage”. Then set to “All Cores/Offset:Negative/-30” or whatever you want to try. If you’re worried about crashing try starting at -20 or -25
This work good on ryzen 7 5800x ? Ty !!
Great video as always thanks again!
I use the program today. PBO2 Tuner. Follow your steps and I get my CPU (Ryzen 7 5700X3D) to - 50 maximum undervolt. This setting passed the 10 min throttling test. From stock temps 73.5°C to 66.4°C and from 101.47Watts to 84.94Watts. CPU up to 4149 MHz. And a score 13663 in Cinebench R23.
This has certainly made things much better for me after installing a BIOS update specifying "Enhanced performance for 5800X3D". All it did was run hotter and louder, and not any faster.
I had set -20 in the BIOS which helped, but couldn't go any lower using the BIOS settings. This software is letting me run at -35, making things much more bearable but still not quite as quiet and efficient as the older BIOS.
Runnig a 5800X3D on an Aorus B550m Elite, cooled by an Arctic Liquid Freezer II 240 on two of their new P12 Max fans and MX-6 paste.
-30 should be the lowest point in the PBO2, -35 seems not ok 🤔
@@zeebm_ I think he might be confused because the PBO Tuner software lets you enter any value and it will say: "Applying curve: -35|-35|-35|-35|-35|-35|-35|-35", and the numbers change in the software but if you close it and open it again you'll see it's all back to -30 because as you say -30 is the lowest point for the 5000 series.
@@gunnarthegumbootguy7909 As I understand, e lowered -20 in the bios and -15 more on PBO2. I do something similar. I have -20 at bios all the time and when I want to play I add -10 on PBO2. Over -20 at my bios wasn't stable when idling. It crushed a few times. Doing that I have 4.3mhz on all cores 4.5 on single threads peaks when I am on the browser and 4.45 on all cores with 4.55-4.6 peaks when I play Far Cry 5 on 60C
Do you have to turn PBO off in the BIOS before using the PBO tuner?
do you know the anwser now?
What got me the most temp drops but maintaining same score points in cinebench was disabling turbo completely and run it at a fixed speed. I run mine at 4.4ghz with a slight undervolt (i'm not sure how much). I have a small case so temps are important (NR200P MAX).
5900X:
Stock temps: under load instant 85c
PBO (similar testing like your video): NOT instantly 85c but gradually, PBO tries to maintain boost clock until the temp won't let it anymore and will eventually downclock to stock core speed 3.8 (in my situation)
With fixed clock speeds and undervolt: i barely hit 80c, usually hovers at 78c which is more comfortable with me as the heat of my strix 3080 also passes through.
what kind of cooler for CPU?

Panjno video! Also known as Christmas in April !
5800X at -30 and is stable as a rock. Temps are staying much cooler too. Thank you for this video.
So I watched your video, tried it and I was surprised that my CPU was stable at -50. The difference in terms of temperature is a 5%, still good since I live at Philippines so it's hot. Did the 10 minutes test and yup, stable at -50
I'm building an ITX system here is my current results:
5600G in an ASRock B550M-ITX/ac motherboard
CPU PBO: -15 -25 -25 -15 -25 -15
GFX PBO: -30
2x16GB Crucial Ballistix 3000 at 3333MHz 16-18-16-16-34 timings and 1.27V
(I managed to reach 3933Mhz CL18 but the extra voltage and heat doesn't worth it for me)
SoC: 1.115 -> 0.918V
NorthBridge: 1.050 -> 0.990V
here are the power consumption data from the wall, software readings are useless all over the place
idle: 21W
Aida64 CPU: 63W -> 56W
Aida64 FPU: 93W -> 86W
Heaven benchmark 53W ->49W
PBO was hard set, because the CPU is heat sensitive, 1 core benchmarks will not show if the undervolt is stable, I could push some cores to -30 PBO if the temps are under 60°C, but fails over 65°C. The fastest stability test is heat up the CPU in Aida64, then run the memory and latency test, if the system not stable it reboots instantly.
Originally I wanted 5300G but the 5600G is cheaper to get so maybe I will disable 2 cores if it gets too hot in a tiny case.
I see you are running a MSI motherboard have you tried Kombo Strike i have and scored a 14000 on cinebench r23 on a 10 minute test.Just asking.With my R7 5800X3D.
Great video but what you wrote underneath it is confusing. I have a Ryzen 7 3800X , so are you saying this program WON'T work on it ? Am I correctly understanding you ? Thanks.

Adjusting the vcore or using this programm?

-what are the pros n cons for pushing past -60?
Should I just go back to -30 and call it quits?
is this advisable for gaming laptops as well?
I used the under volt in the bios, very easy, applied a -30 under volt. Depends on the Chip but please try it. The chip will run faster and cooler. Win win. Each core ran at 200mhz faster and cinebench scored an extra 500 points.
That's nice. I wasn't that lucky but still managed to get -25.
same here, found the BIOS setting for core voltage and just set a negative offset of -30 on all cores. So far it’s been stable during long gaming sessions on my off days. Temps never hit the 70s anymore unless the cpu runs a heavy load during processing like when I run Dyndolod for Skyrim modding. Although last night I did notice sometimes in Baldurs Gate 3 i’d get a short hitch after saving the game or opening the pause menu. So I might go to -25 if it keeps happening. Never had a crash tho in any game
Nice tool!
You can adjust undervolt on a per core basis by looking at which core has crashed when undervolt is too low in Event viewer then only raise this core by 5, rinse and repeat
Thanks for this tip about event viewer. Going to look into that.
@@chrish7927 use corecycler instead.
DONT DO THIS IF U PLAY VALORANT, I tried to do it and vanguard popped up saying that the program wasnt ok to use with vanguard installed, not worth getting banned for. Ur tweaks normally are great tho keep up the vids
Wrong. Using it for months, playing Valorant / CSGO Faceit etc daily.
Not even one single problem since using it.
TL:DR It's completely fine to use with any modern Anti-Cheat
fiddled with my bios and punched this numbers to my Ryzen 7 5700X.. cores 1-7 is at -26 and core 8 is at -24. boost Override CPU is at +200Mhz, PPT: 112 TDC: 75 EDC: 105.
In R23 all core it can maintain 4.4Ghz at 73c with a score of 15,003 points highest (but the average i get is 14,860+) single core score 1,530. prime 95 large FFT's maximum temp is 80c 10 min run with no crashes and stable. cooler is be quiet dark rock pro 4 with custom high rpm fans.
I prefer using Prime95 with both AVX2 and SSE testing to get my CPU stable. I was stable in Cinebench with my worst (by undervolting) core with -12 setting, but Prime95 was almost immediately crashing on both corresponding workers. By reducing that core to -6 it became rock solid. Other cores were way better with -15 to -28 setting.
And yes, you can fine tune it on per-core basis, it just requires more time.
Got my first AMD two weeks ago, 5800X3D, got it running -30. Seems to hold, been playing all day with it.
How has it held up? Just got my
5800x3d yesterday. -30 is working great so far but curious about long term issues
@@teddyholiday8038 I've run it every day since, never had an issue.
Is there any significante inproovement from -20 to -30?
I think i am doing something wrong. I went up to -50. My cinebench score is up to 13970. But my average clock is 42350. Should i try to go past -50
The problem with all of these stability test is that these tests are not 100% trustworthy. I had crashes days later randomly. You have to see if it runs using your PC in the end.
I used Ryzen master software with my 5900x till I got good values. Than added it to my bios settings. But it takes a long time and isn’t really worth the trouble in the end in my opinion.
We want this for all CPUs from Ryzen...
nice video thx for the help
Hello you dont need this Tool !!! Kombo Strike in Bios Settings is the Same. 10 = -10Undervolting 20= - -20Undervolting and 30= -30Undervolting
do i need to start pbo2 tuner every time when i start my pc? Or does it safe the settings and automaticly apply for every reboot etc.?
Whats the difference of doing this operation with bios and with this way? Instead of starting pbo software everytime just tweaking via bios one time seems so much practical. Thank you for this video btw.
Im running a 7 5800x (non 3D) and somehow reached -50 without crashing?? Is the software out of date?? When it tried making it -55 it said "Out of safe range" and i couldnt make it lower than -50
Edit: Just did a 10 min test at -50 and yeah it didnt crash. And btw forgot to mention i got about 200 extra mhz
Edit 2: My pc crashed while running GTAV, and even if i set the value to -45 it automatically makes it -30 when i exit the app.
I actually had to raise power modes to get my full boost speeds. In games I was seeing 18-32 watts now it’s 40-60. This is the 5800X3D it’s a little hotter now but not noticeable with my cooler. Temp’s average 40c
at 60 watts 40c is still cooler than my 5800x non 3d at 65w 50c
I was just saying the average temp. It can go higher but I use a 420mm radiator AIO cooler
Do a updated escape from tarkov FPS boost video please
Finally PBO overclock. Need to do this on my 5800x
I have a 5800x and I’m stable at -30 👌🏼
@@Shadow4ko hey man same but how do u save it , i used this app and then restarted and the values turned into 0 , well i used to pbo limit in my bios so do i do that ?
@@muntasins he explains in the video/ You have to do it every time you boot or save it in bios or with task scheduler.
Save the undervolt values for each core in the BIOS. Ryzen Master has an automated utility that will test all your cores and recommend an undervolt for each core. Once you save it in BIOS you won't have to set it again until you do a firmware update (write them down somewhere). I undervolted my 5800X and brought my temps down to where I don't hit thermal throttle in the most demanding games I have and the CPU runs at full boost all the time.
Can i use ryzen master and pbo tuner?
holy crap this actually works
What are your cyberpunk settings to get that fps? I have the same system 3080ti and 5800x3d
Thankyou!
hello thx for the grat work, are a msi B450M A PRO MAX 2 and a RZ 5600X elligible with pbo and this tutorial ? i ask because in system i have ms-7c52 and when i type in google it gives A320 PRO but i have b456m a pro max 2, kinda confusing
Got a question. I just upgraded to a Ryzen 5 5500 and when I checked the BIOS for PBO, it was set to auto. Now, I did not change that setting and followed the instructions in this video. However, it seems that I'm not getting much of an increase, and even sometimes get less score on my Cinebench R23 results. I've reached an offset of -40 in my testing and the most I got out of my cores was around 4270+mhz, which was hovering the same amount with a -10 offset. So, should I turn PBO off in the BIOS before I do this again, or is this irrelevant and should work regardless if my PBO is set to auto? Would really appreciate it if you could reply. Thanks
HI Panjno! Would you kindly do one of these UV/OC vids for Ryzen 3000 CPUs and B450 motherboard? Maybe an updated one for 2024?
great video mate i tried this with my 5950x & X570 board but my core clock speed stayed at 4099Mhz 155w and a temp of 50c i got PBO2 tuner down all the way to -50 and it was still stable but nothing appeared to be changing in HWMonitor. any advice on that?
Thanks it helped ^^
ok is it normal that my computer performs best at -50 and doesnt crash? is that too far or is it ok to just simply go as low until it crashes, granted i havent tried a game yet only done using cinebench
i use balanced power plan and my clocks seem normal but cpu usage still spikes at times will lowing the core curves give me less fps in game?
Should you have already installed Ryzen Master and set the OC mode to PBO or should you not install/use Ryzen Master and use this instead?
Does this work with laptop motherboards? I have an ideapad gaming 3 with r7 5800.
This video doesn't go into Clock stretching and can mislead people into getting worse performance. If you can edit in a small pice to make sure your effective cores freq match the core clock. (this was happening on my CPU)
Edit in a small pic to a already published video lol. End of the day. If you do this and it’s not working properly, clearly you don’t know what you’re doing and should just avoid it
Thanks! Way lower temps and better performance!
Does this work on a Ryzen 7 3700X 8 core ?.....I have a MSI MPG X570 Gaming Plus Board...
Does the PBO program have to be open in the background or can i close it after applying the undervolt?
In my case Ryzen R5 5600X it was stable at (-23), Realy cool tool.. Thanks alot for sharing it realy helps ❤️
I have -30 on ryzen 5600x how low are your temps with that offset
@@UltraxHere
_Without the offset .. On cinbench R23 im getting (11467) points + temp (82.5) celsius
_ With the offset (-23) ... On cinbench R23 getting (11759) points + temp (75.3) celsius
Perfectly Stable at (-23) , any higher even at -24 iam getting crashes sometimes
Note: SORRY for the late reply 🙏❤
@@UltraxHere
Oh .. BTW my ram is (HP V10 RGB 32GB DDR4 3600MHz CL14 2x16G) Dual channel + Dual Rank .. as the frequency & Latency of the ram affect the performace specialy with ryzen cpus
Does this work with laptops? I have a 5800h
Unfortunately, Cinebench is not a good test for curve optimizer stability - I had a 5700X that would do -30 all day, but would crash while web browsing.
CO instability shows up at the HIGHEST clocks, which is at the LOWEST load, and Corecycler is the best tool for both testing and diagnosis; it has tests that simulate very low loads and tells you WHICH core has failed.
I have an AMD Ryzen 5. In my Acer nitro 5 laptop does this still work?
I was lucky enough to be able to do -30 on a 5800X3D via the bios. I have been tempted to go lower, but it does really well where it is :).
-30 is the lowest you can set it to on any 5000 series cpu anyway, but for 5800x3d with a recent bios update -30 should be stable for every single 5800x3d out there. For everyone who has a 5800x3d, looking for bios updates is absolutely worth it, they've fixed a lot of stability and performance since it was released.
@@gunnarthegumbootguy7909I was lazy to do any testing and just set it to -30 in the BIOS and haven’t ever crashed yet while gaming or idle. so i assume it’s fine lol Main thing is my temps no longer touch 80c at all. Usually floats in the 60s while gaming, occasionally hits 70s during heavy processes like when I run Dyndolod for Skyrim modding
Wait I shouldnt do this if I have a high end gpu but ryzen 5 5600x should i?
Do you have any software like this one but for GPU’s? So I can overclock it as easy as this??
5600X and MSI B550 tomahawk, I just set it to -15 and it has dropped the power and temps by 5-10% (roughly). I didnt do any further testing after -15. It's fine.
I noticed my 5900X is locked at 3.7Ghz on my Gigabyte X570 motherboard. I have to manually dial in the ratio and do an undervolt in the BIOS. This software did nothing for me. How do I switch this off in the BIOS?
PBO2Tuner says unsupported CPU model. I have a Ryzen 4600H. Sadly I haven't been able to find a software that helps me undervolt my CPU. It's been a hindrance when gaming for a while now.
Thanks for this awesome Video🙏🏼🔥 So i safely can use this on my Ryzen 9 5950x right?👀
try set -18 on all cores for ur 5950x
Is this applicable to laptop? or just desktop users only?
Did it on my laptop. Seems to be working great so far.
will a cpu undervolt and gpu undervolt toghether give a higher performence for my 5600 cpu with a 1060 6 gb gpu ??
The issue with using PBO2 tuner is that you have to set up a task on windows and do task scheduler that not always works. otherwise you have to do this every time you restart or start your system. you BIOS is easier.
BIOS is easier if you set it stable, its easy for people to quickly test and run into instability on SOME games/tests. If you
@@Panjno lmao why are people so lazy i turn on my pc have 5800x3d it takes maybe 5 seconds i tab and put -25 on all of them boot up my game stream and discord and play lmao
The tool is for TESTING for stable UV without needing to go into BIOS everytime you crash. Once you figured a stable number only THEN lock it into the BIOS.
Im not able to go above my CPU base frequency during Cinebench multicore test. When not running the test with turbo boost enabled, ill get around 4.4ghz max. Why is this capped during stress test? My cpu: AMD Ryzen 7 5800H Radeon graphics. 3.2 base clock
can i undervolt my 5700g APU which is running without a graphics card?
How to know what chipset i'm using as my system model is 82JQ and i'm not getting the information about which chipset i have can you help me to know about it
I use HYDRA instead on PBO tuner. It starts with windows, so i don't have to think about it. I would use the bios thing, but HYDRA is better for performance. Meaning, my 5600(nonX) takes different values for each core( -22,-23,-30,-24,-24,-29) ,reached these values testing with OCCP each core separately. All fine and dandy, i could punch in these numbers in bios as well. However HYDRA has a setting where all these values go to -30 when CPU is working at over 70%(or whatever percentage you want). And tests pass with -30 all cores if cpu works hard, My cores are not stable at -30 if i do normal stuff like browsing or whatever meaningless tasks. It is stable when the processor works up a sweat though. Pretty interesting if i do say so... I tested this myself after i saw some people talking about it on some reddit page.
Do you have microstutters with that cpu
@@ispodstrehe3065 I haven't noticed any microstutters. Gaming is pretty smooth. Why do you ask?
@@cristianitsirc6830 i have a little bit, does it better perfome undervolt?
@@ispodstrehe3065 Well, numbers don't lie. Synthetic scores went up a bit, like 1000 in cinebench R23 for multicore.
I haven't experienced microstutters even when the cpu was at stock. I do the undervolt thing pretty much because the temps are lower. So, performing better is just extra bonus.
Link for hydra?
Bro killed me when he said hiccups 😂😂 imagine your pc is hiccuping 😂
