@@ImWateringPSUs I wanna set mine for gaming only. So if I do the curve optimizer say -20 do I also mess with the TDP and the other two pbo settings or just set it to motherboard. Any help will be great fully appreciated
@@kinneyjr740 you can just do it with the pbo preset it does the same as doing it manually just less steps and can't change it as much but that's why it's a preset. Try some presets and see what gives you the best performance. I'd look into doing it to your gpu as well lower voltage can help with stability by running your card at the same or a slightly higher speed. You can also just see how high you can go before it stops being stable
Amazing Video!!! I did the first one -20 and my Rust FPS boosted from 120 to 140-180 while having 5-10celsius less temps!!! Tyvm ❤️😁 (specs - ryzen 7 7800x3d, XTX 7900, 32gb 6000mhz, Asus X670E-F gaming, 1440p 165hz.)
I just built with it over the weekend paired with 32 gigs of ram and an rx7800xt the cpu has been running around 45c cooled by a deepcool ak620 zero dark air cooler
I'm gonna make my next build with this CPU when I move to Spain (it's gonna take a while but I'll worth it) maybe with a 4070 Ti Super or 7900GRE if the RTX doesn't reduces its price.
Thanks a lot for this, I used the dynamic undervolt on my ASUS X670E-E (BIOS 1905) and my 7800X3D, whilst gaming (Cyberpunk / The Last of Us Part 1) it runs average 64c (cpu package) whereas before it was running around 77-80 average.
@@zGiGi "Dynamic undervolt" is the first thing introduced in this video. It combines temperature limits and Curve Optimizer settings. (Google Translation)
Bro, my 7800x3d got to 68° in the last of us 1 during gameplay and I got concerned, past 75 is Insane, rip your cpu. What cooler do you use??? I have a noctua with 12 case fans running 1750rpm profile
I did -30 unvervolt and f10. Cinebench was 16028 stock. After undervolt it's now 17800. (Multi cpu) 7800x3d. Thanks dude. Temperature was 80s. Now 70s under load
Thanks so much for your clear instructions! First time using AMD and had no clue going in. Got my r7 7800x3d @ -25 aiming for 80°. Cinebench r23 score was 18100. Edit - ran Cinebench with high priority. Same settings. 18402
@VideoGamePlaythrough842 I'm seeing mid 40s idle and mid 60s when gaming with a Ryujin II 360. Runs a little hotter than my old 9900K but totally normal
Just did a bios update becauso my bios was corrupted and my cou settings were set back to default, I used your video to do it because I did not remember how to do it. Took my 3d mark cpu score from like 12.8k to 13.4k or smth, so not massive but definetily worth a 👍 Started with 30 I will increase it to see if I won the silicon lottery :)
PBO curves, by themselves, are not really a power reduction mechanism even if they do nominally reduce idle draw a bit. The whole point of negative PBO is to make room (in voltage) for more and longer-sustained overclocking, including via built-in mechanisms like CPB. Also PBO curves affect the CPU stability on idle and not underload, -20 is quite unstable on Ryzen, the maximum you should aim for is -15, don't be surprised if you come back from the bathroom (leaving your PC idle) and find out it crashed. So no, this is not the right way to undervolt your CPU...

Hi. The tutorial es easy to understand and I will try it ASAP! Meanwhile, I already suscribed and gave like. Only a question! When you set the PBO and the Curve Optimizer, that is the first preset for "gaming", but you also get lower temps, isn't it? Or am I missing something? Thanks!
Hi! Thank you for the video.. General question, is this safe to do? Its not going to do something bad for the cpu? Doesn't it harm the processor over time? I only have those doubts, because I never touch voltages or strange things in the bios... Only xmp profile.
SOC Voltage is as the name says for the SOC and not for the cpu/cores. And the stable voltage depends on the ram. I have hynix a-die. And can run 6000 MT/s with 1,075v.
so I just found out about ccdg global voltage setting in bios. when you are using a ram oc profile, it will set to 1000mv automatically. I changed both global ccd settings to 950 & mouse movement / gameplay is way smoother. I’m going to play around with other voltages for the 3dv cache so I’ll update this thread. my theory here is… better temperature for the 3dvcache will make things much smoother. and so far that’s what I’m experiencing
@@TheAquaBuilder so for any motherboard the rule of thumb is - when you turn on xmp and then save + reboot, voltages will automatically be set because of the xmp profile that was set. if you are not using 7000mhz & above you don’t need vddg iod / vddg ccd at 1000mv. So setting it to 950mv will be perfectly safe. depending on the quality of your chip, you can probably set it lower in increments of 5. Have any other questions ?
thank you i think this dropped my temps by 9°C on cinebench and still running at stock speed no problem. this will help me get through the summer it's burning hot around here. already undervolted my gpu as well =).
@@ImWateringPSUswould you recommend the first or the second way of using pbo (I haven’t tried the part where you say static). For the first part with the thermal limit and curve optimizer i level 1;2;3 all are unusable i have a sff pc and games like warzone start running super inconsistent and because i seem to get thermal throttle with level 2-3. with level 1 it’s a bit better but it feels like i have way more input delay l, as something is if something is slowing down the pc. Alao with pbo my cpu time in wz went from 2-3ms (i tweaked windows and bios) to 10-15 ms which feel super unresponsive. I just bought new fans for my aio which have higher static pressure and some for the bottom of the case and put all to exhaust (nr200p max) and now reverted all bios settings and left pbo untouched. Gonna try the static version you mentioned to day maybe jt works better! :)
Uninformarive video, pbo negative offset can really mine stability, it is a setting that requires a lot of testing, expecially if you want to have a 100% stable system by setting it per core.
I think AMD disable the CPU clock ratio/multiplier for 7800X3D, only let PBO decide which clock the CPU would run to match the set up of SOC voltage/CPU curve. I can not find that setting in BIOS of MSI X670E Carbon either. (Correct me if Im wrong, many thanks 😅😅😅)
The Dynamic option sure, it's basically what we're doing in the tutorial! The static option no, PBO will automatically be disabled. 80/20 is very good, I'd keep it that way personally. Glad to have you watching multiple of my vids!
@@ImWateringPSUsgot it, basically just another way to skin a cat? Or is there additional benefits to using this tutorial? And for sure brother love when I need to learn something and your channel pops up!!😂

idk for the 7000, but on my 5700X, the best Curve Optimizer I've found was -10... 0 it gets too hot, lower than -15 it loses performance on Cinebench... at -10 it keeps well below 75ºC on my cheap cooler and has the best performance
I just gave it a shot and set it to minus 30. Nothing happened. Then I set it to minus 40....no issues. At minus 50 it went black instantly. So I left it at minus 30. Temps are a little less, performance is a little bit better. But even at minus 30 do not expect any magical improvements. Temps went down from 85 to 79. Performance-increase of about 2%.
I hear you say on a few occasions that with certain settings applied, the PC can crash. What’s the best way to check for stability at certain frequencies? Is there a good benchmark to run?
@@Kocainn so it’s good to run this to test the undervolt? How long should you run this for to test the stability? Will one run do or should you do several?
@@Jacketz123 I ran mine with these + undervolt settings for 20 minutes on both single and multi core. Then I hopped on some CPU heavy games for further tests. I had no issues
can undervolting a 7800x3d possibly hurt anything? Like the internal memory controller? The reason I ask is that I recently had to replace my 7800x3d because of a bad memory controller. I had a -30 on all cores PBO on mine. I would run some stress test and I never had any problems. To be honest I never really had any issues running -35 on all cores either. ITs just the gains were marginal so I just set it at -35. But one day my computer woudn't post to bios. I thought it might be a bad RAM, or MOBO, so I replaced those, and I still couldn't post. It wasn't until I tried replacing the CPU did it just boot up just fine. I probably replaced the mobo and ram for no reason. I actually didn't replace the ram, I bought new ram to see if it was the issue and it wasn't. I was trying to run AMD EXPO of 6400 cl32, but I capped the speed at 6000 just because peopel said the 1:1 ratio for the infinity cache was optimal at this speed. I'm trying to find out what could have caused my CPU Internal memory controller to go bad only 3 months old. Could it have been running AMD EXPO? Could it have been running undervolt on cpu? Could it have been the damn cable mod extensions?
@@ImWateringPSUs I understand. I think I might just keep the ram at stock settings which I think is 4800 m/t. I honestly don't want to go through the hassle of replacing the CPU again because of a blown memory controller. I'm just trying to find out what could have caused it and rule out the other things I've done. On my new cpu, so far I'm testing it at -50 PBO and it seems stable but I want to try other test to see how stable it is.
probably enabled expo together with a Mobo bios version prior to the max 1.3volt fix. I had the same thing it was really creepy as i was testing out a game before updating bios.
For the 7800x3d, you do not have the option to manually set the CPU ratios or Vcore. You can only set an offset but you cannot for example set all cores to 48, the motherboards lock this setting for the 7800x3d
Thanks im doing -30 CO all core on my 7800x3d and getting max clock and 60 or less degreas average while gaming but i use termal trotle limit at 70 to stop the spikes of temperature im very happy playing cs2 at 52-54 degreas on mirage 600-700 fps

Sometimes I think about undervolting both my 7800x3d and 7900xt, but I read horror stories that in the long term (even if all stability tests were passed and everything seems to work well) it can only get worse (instability in specific moments or downtime, etc., which will only worsen the condition of the CPU and GPU in the future) I don’t know what to do, I kind of want to, but I’m scared
I tried to replicate your settings, but the MSI bios are quite different, and I can not find the enhancement setting. Please check how I can do this. I need undervolting my CPU as I will change the cooler system in 3/4 months, so it's better to do it now. I have a B650 Tomahawk MoBo and, of course, a Ryzen 7800X3D.
I’ve just bought my 7800x3d and will get on Sunday. Will try ur guide to overclock it for game. Hope everything will be fine) But this will be my first time with AMD CPU, so probably I’ll have some questions to u later Liked and subscribed btw

I have a profile on asrock ripetide motherboard that sets max temp 85 and undervolt -40mv. I dont think it ever crashed. but the CPU has always been used below 50% under any load. How can I know that its actually using undervolt ? the max clock used is 5050 for this cpu as advertized.
I set all cores to -30 with an PBO on 80 Celsius limit, and my temperature was the same in Battlefield 2042; I just don't understand the point of undevolt for the 7000 series! I have a 7800X3D, and I don't notice any changes in games; the CPU is running great, and the only heavy CPU game I observe is 70 degrees Celsius, the rest are 59-65 degrees Celsius!
recently computer has a single click/tick sound in the system once in awhile (i can confirm its not any of the case fan and cpu fan) so im playing around with the undervolting to see whether it works... any idea what can the click sound come from? another question is can i use both dynamic and static at the same time? for eg, PBO all core set to -25 and thermal limit to 80 + SOC voltage override and i set it to 1.20v does both of these work together or its either or? i also set my maximum proccessing power to 99% to disable the turbo boost of my 7800x3d which can get quite hot. thank you in advance!
I tried negative 18 and it crashed when loading games so I’ve set it to negative 10 and it’s all good to go. Is negative 20 stable for you playing a game?
you gotta really test it , 15 usually works but remember about your 2 best cores. Use amd ryzen to check what these are. You wanna undervolt it a little less. 10 for example compared to 15 since they're really sensitive
Definitely agreed! I usually recommend against per-core optimization because it’s a little harder to test stability, but sometimes dialing back just the bad cores help. I’d say try -15 and you should be good :)
Quick question, im using 7800x3d and i tried doing msconfig-boot- used 16 cores. is it okay to do that? if not how will i put it on default? thank you!
I m using a msi 650 for this and i m not getting the thermal limit option ,there are only 4 option for me those are auto,enabled,disable and advanced,what should i do?
What worked for me was setting it to advanced, which then brought up the thermal target or something similar. Hover over it (make sure it is highlighted) then type in the limit
Nice tutorial, i've done set up the core offset but unfortunately on my asrock b650m pro rs there is no pbo limit based on the thermal degree. I only can set it by wattage, is there any solution for my case?
Thanks for the Video, so gonna test it when i am back home. Yesterday i got me a midrange AIO WaCo, and the 7800X3D stays around 58~62°c in Prime95 after 30 Mins. I am curious about how much the -20 curve will boost performance in synthetic benchmarks and gaming! PS: Sub out!
Hi.Insane vid. I did first one (dynamic). I got more fps and no microlags while playing high fps games with 240hz monitor. But in games like PUBG i have high temp like 75-80. I wanna lower it a bit. Should i do lower negative (like 25-30) or lover limit (like 75 may be). I have MSI b650 mboard and i can set Power limit throttling on 75 or 70.
I’m really happy it was helpful! Thanks a lot for taking the time to leave some feedback :) Consider subscribing if you wanna support the channel! For lower temps, lower the temp target
Not really doing anything for me. No performance, same temps, regardless of me setting it as -20, -25 or -30... What am I doing worng? Followed every step in the video
what would be the recomended coolers really for the 7800x3D? im torn to choose between the NZXT H6 Flow or the Lian Li O11D EVO case wheres in the NZXT is between the Arctic LF3 360 or an Thermalrigt Peerless Assassin 120 or in the Lian Li the Arctic LF3 420 or a Peerless Assassin, (i do get that AIOs might be complete overkill so its more for the esthetics) but a "bigger" AIO comes with the benefit to run the fans alot slower to lower the fan noise and with the VRM fan on the LF3 to also cool the VRM sounds like an benefit aswell?
Do i need to update my bios to the latest version before undervolting my 7800x3d CPU like this? My bios is currently 1807 and the latest one is 2616 on rog strix b650e-f motherboard. I built the pc some days ago and i have no stability issues so far. My current CPU temps are 45-47 idle(each core is like 30-35 degrees) and like 60-65(MAX) when gaming and having webbrowsers up. The fans are at 800-900 RPM standard curve with these temps.
Out of curiosity, granted I’ve not yet watched the video, I’m at 0:58 but how can something work the same between the 3 ryzen 7000 x3d CPUs? They are made significantly different. Like core foundations of the chips are different. The 7900x3d and the 7950x3d both have two separate CCDs while the 7800x3d only has one. There is a lot of fiddling with the 7900 and 7950 x3d chips (like disabling one of the CCDs)to get them to game at the highest level while the 7800x3d is good to go out of the box. I’m going to watch the video but so far it’s not making a lot of sense how you’d do the same with all 3 chips
Also I truly appreciate you saying if it works for you to hit the like button. Rather than telling people to hit like before watching even 10 seconds of the video
“Good to go out of the box” Seriously? With 55-60°C at idle and great 360 aio cooler and no changes, no curve optimizer and no SoC change. Even if you use the 7800x3d, you still have to use the undervolt. I use it and package temps drop by 25 degrees. From 65°C to 40°C and CPU temps (not the package) drop from 55 to 35° on each core. Cinebench score has an increase, out of the box the CPU scores 14400 pts and with the curve optimizer and SoC change scores 16200 pts. 😊✌🏻
Very good point of criticism, however it is quickly explained: the overall tweaking can and will be different (disabling CCDs, different RAM tolerance) however as far as undervolting goes, they all share the same architecture and X3D chips have all the same kind of binning. So the voltage curve and the way it behaves is shared
@@jakubpokorny5436 you may get better numbers running an undervolt but you absolutely do not have to undervolt it. I’ve got a 240mm aio and never reach even 80c under heavy load. Not everyone has to screw with power settings
@@jakubpokorny5436 so yeah the 7800x3d is good to go out of the box. I put the cpu in and it games perfectly. Sure maybe I could get 10% more by undervolting the CPU but there is other crap you have to do with the 7900x3d and the 7950x3d that you simply do not have to do with the 7800x3d, so yea my point remains, it’s good to go out of the box without screwing with power settings. But what do I know? I only upgraded from the ryzen 5 7600x and got an incredible bump in my gaming experience while having access to all 8 cores. Guess what? The 7900x3d has access to 6 cores with vcache for gaming. The 7950x3d has 8 with access to the vcache. The 7800x3d beats them both in gaming and doesn’t have to cut out half of its damn cores to access the 3D cache

I am using ASUS B650 MB and there is something confusing: I have AI Tweaker which has PBO settings and under advanced tab there is AMD overclocking which has PBO settings aswell. which one has priority? what if one is set enabled but the other one is on auto or disabled? I did undervolting just as in this video and after stability tests and benchmarks there is NO change in power consumption or temperatures (facts: it was about 0.1 Watt and 0.1°C difference). any advice? super weird
Dude there is so much just wildly incorrect info in this video. Curve optimizer is an offset to frequency? No. SOC voltage is the same as core voltage? On WHAT planet is that true? Just unadulterated ignorance. Max SOC voltage for 7000 series is 1.225? Lol. Wrong.
Ever since I bought my 7800x3D, I couldn't enable PBO. It was causing system instability, very slow and choppy. It looked like a Pentium 1 and my temps were at 80+ idle. But for some reason, by enabled PBO with 80 level 3, curve all core negative 20 and it worked
What if I only have PBO advanced? Do I only put the offset to 20 and be done? Edit: the only difference with this setting is that it doesn’t give me a thermal level selector
I have the AsRock Phantomgaming Bios and i cant find many of the options as described in the video. Like Thermallimit(its a manual number so its present but cpu voltage under the Tweaker Tab is nowhere to be seen? Could it be called something completly different in this case?
I have OC tweaker but the names for the options are either completly different or not there. also what is supposed to be a multiplier wont let you input 48 like mentioned in the video.
Grazie! Col 7800X3D il problema non c’è mai stato perché ha solo core X3D. Se hai il 7950X3D, allora si. Tutt’ora. Ci sono dei tool per sistemarlo ma bisogna farlo per ogni gioco
Buddy, on my Motherboard (asus rog b650e-e gaming wifi) with 7800x3d i can go up to negative offset of 35/40 in the curve optimizer without crashes...good or bad?😅
On CPU SoC Adjust i've seen lots of people, including you, say 1.2V, but mine is 1.020V on default?? Checking right now on BIOS and HWinfo and you go to motherboard section, CPU NB/SoC and it shows 1.020V...
Is undervolting really necessary? Complete idle at 45C. While watching youtube videos its about 55C average. Gaming 60-82C usually in the 70's at least?
@@southwestwindwhat gpu do you have ? have you recorded the maximum frequency while it hits a certain hotspot ? Have you recorded how much voltage is being drawn at said hotspot & frequency ?
@@southwestwind for ampere go -300 on the core always. Since you have a 3060 just go with 850mv at 1925-1930mhz & you will see an improvement. you will have a static clock speed that doesn’t decrease because of the offset on the core + undervolt.
Ciao mitico e complimenti per il canale, sei top! Comunque senza pbo enhancement ma advanced con curve all core/negative e -30 più altri vari set che non sto qui a scriverti perchè sono diversi ( tipo IOMMU disable ) il consumo in idle sta sui 37/38 W, con chrome aperto anche picchi di 42 . Invece con il bios a stock stavo sui 22 W ma temp più alte. A te risultano questi consumi? penso sia normale per il 7800x3d vero? 🤔 Grazie
Intanto grazie mille! Andando solo di negative PBO offset non ci dovrebbero essere risultati negativi sul voltaggio in idle. Attento a non aver cambiato lo scalare della curva del PBO oppure qualche setting del risparmio energetico, comunque un consumo idle medio si attesta intorno ai 25/30W, dunque i tuoi valori non sono troppo distanti da quelli che ci si aspetterebbe, considera anche che ci può essere qualche processo extra che gira in background!
@@ImWateringPSUs grazie a te, farò altri test, considera che a stock se non ricordo male stava sui 22. In ogni caso la config di adesso è stabile a -30, sono vari set se riesco te li elenco qui sotto appena posso… lato temp va da paura, meno lato consumi in idle
I did only the dynamic way. Which I find is more stable for me. I set my curve to -30 (-40 was not stable). Now i see the clocks reach 5Ghz regularly, especially at lower % utilization. My 0.1% and 1% lows have improved as well. Power never exceeds 60W (stock would reach 60-70W). Lower Temps, lower power usage, better performance. Why not?

I don’t have the option for Thermal Limit in my Asus bios. I only see PBO Limits, PBO Scalar Ctrl, CPU Boost Clock Override, and Platform Thermal Throttle Ctrl. I’m guessing it’s not the last one since you have that as well. Never mind there seems to be two PBO locations. One in the Advanced section and the other in the Ai Tweaker section. The one in the Ai Tweaker section shows Thermal Limit as well as the Enhancement PBO setting.
@@MrGordi320 I was able to set it to 80 but for me it was Level 2 instead of the Level 3 shown in the video. I have a Asus B650E-F motherboard so it might be different for you. Set it to 75 or 85, there shouldn't be an issue since I don't think you'll be reaching those temperatures anyways if you have the Curve Optomizer set Negative.
@@MrGordi320 To enter Tweaker section you have to be in the Advanced Mode view. When you enter the BIOS you'll probably be in the EZ Mode view, at the bottom right you'll see Advanced Mode. Either click it or press F7 on your keyboard. From there you'll see the Tweaker section at the top.
I had mine hitting low 90s which isn't safe at all, it's max is 89c. For productivity it was unusable, since anything over 80% usage caused it to get to hot. I've got a thermal limiter and the PBO settings on now, so it won't go over 80c and still performs just as good. It's concerning to me, I got a massive case, with a 360 X73 AIO and both my 5900X and 7800X3D would get real hot and we able to be undervolted quite a bit without a noticeable performance loss.
I face exactly this problem, it is really weird, while gaming I never went upper than 55, but on chrome easily 64, with 71 at worst cases(this is my temp spike while playing cyberpunk at max graphics in every aspect), it is ridiculous having same temps on cyberpunk and on a web browser
This method will also work for a 5800x3d -30 on all cores. If your motherboard has pbo tuner I set mine to ppt-100w tdc-75a edc-100 This Will help with Lower temps and keeps the cpu from thermal throttling…..Happy gaming yall

whats the dynamic undersvolt ????
Is package more important than individual cores?
@@zGiGi "Dynamic undervolt" is the first thing introduced in this video. It combines temperature limits and Curve Optimizer settings. (Google Translation)
Bro, my 7800x3d got to 68° in the last of us 1 during gameplay and I got concerned, past 75 is Insane, rip your cpu.
What cooler do you use???
I have a noctua with 12 case fans running 1750rpm profile
I did -30 unvervolt and f10. Cinebench was 16028 stock. After undervolt it's now 17800. (Multi cpu) 7800x3d. Thanks dude. Temperature was 80s. Now 70s under load
-27 gives 18576
Sounds great! What cooling sys do you use?
Noctua d15s
got 17100 on mine without undervolting, will see results soon

Thanks man ❤, I’m going to save this video until I receive my motherboard.
Thanks a lot for watching :)
Just did a bios update becauso my bios was corrupted and my cou settings were set back to default, I used your video to do it because I did not remember how to do it.
Took my 3d mark cpu score from like 12.8k to 13.4k or smth, so not massive but definetily worth a 👍
Started with 30 I will increase it to see if I won the silicon lottery :)
I just tried 40 and it crashed, 35 did not crash but I did not benchmark it. I am currently benchmarking 37 and it's working pretty well so far.
Just tried -35 and I got 13.25k, weird how I get slightly less performance with a lower value 🤔
Thumbs up and subbed. Used this tutorial a few times when I first started bios changes and consistently return when I forget how to do it.
PBO curves, by themselves, are not really a power reduction mechanism even if they do nominally reduce idle draw a bit. The whole point of negative PBO is to make room (in voltage) for more and longer-sustained overclocking, including via built-in mechanisms like CPB.
Also PBO curves affect the CPU stability on idle and not underload, -20 is quite unstable on Ryzen, the maximum you should aim for is -15, don't be surprised if you come back from the bathroom (leaving your PC idle) and find out it crashed.
So no, this is not the right way to undervolt your CPU...
I won the silicone lottery. I managed to get -35 on all cores, and it’s stable.

Hi. The tutorial es easy to understand and I will try it ASAP! Meanwhile, I already suscribed and gave like. Only a question! When you set the PBO and the Curve Optimizer, that is the first preset for "gaming", but you also get lower temps, isn't it? Or am I missing something? Thanks!
Hi! Thank you for the video.. General question, is this safe to do? Its not going to do something bad for the cpu? Doesn't it harm the processor over time?
I only have those doubts, because I never touch voltages or strange things in the bios... Only xmp profile.
SOC Voltage is as the name says for the SOC and not for the cpu/cores.
And the stable voltage depends on the ram. I have hynix a-die. And can run 6000 MT/s with 1,075v.
Me too so gonna try this

so I just found out about ccdg global voltage setting in bios.
when you are using a ram oc profile, it will set to 1000mv automatically.
I changed both global ccd settings to 950 & mouse movement / gameplay is way smoother.
I’m going to play around with other voltages for the 3dv cache so I’ll update this thread.
my theory here is… better temperature for the 3dvcache will make things much smoother.
and so far that’s what I’m experiencing
That’s not a theory, that’s a fact! Running with the minimum possible voltage is always the best :)
Found any good results? Just bought this cpu and looking to optimize
@@TheAquaBuilder so for any motherboard the rule of thumb is - when you turn on xmp and then save + reboot, voltages will automatically be set because of the xmp profile that was set.
if you are not using 7000mhz & above you don’t need vddg iod / vddg ccd at 1000mv. So setting it to 950mv will be perfectly safe. depending on the quality of your chip, you can probably set it lower in increments of 5.
Have any other questions ?

@@ImWateringPSUswould you recommend the first or the second way of using pbo (I haven’t tried the part where you say static).
For the first part with the thermal limit and curve optimizer i level 1;2;3 all are unusable i have a sff pc and games like warzone start running super inconsistent and because i seem to get thermal throttle with level 2-3. with level 1 it’s a bit better but it feels like i have way more input delay l, as something is if something is slowing down the pc. Alao with pbo my cpu time in wz went from 2-3ms (i tweaked windows and bios) to 10-15 ms which feel super unresponsive. I just bought new fans for my aio which have higher static pressure and some for the bottom of the case and put all to exhaust (nr200p max) and now reverted all bios settings and left pbo untouched.
Gonna try the static version you mentioned to day maybe jt works better! :)
Solid video man, thank you
Uninformarive video, pbo negative offset can really mine stability, it is a setting that requires a lot of testing, expecially if you want to have a 100% stable system by setting it per core.

I think AMD disable the CPU clock ratio/multiplier for 7800X3D, only let PBO decide which clock the CPU would run to match the set up of SOC voltage/CPU curve. I can not find that setting in BIOS of MSI X670E Carbon either. (Correct me if Im wrong, many thanks 😅😅😅)

55-60 DEGREES AT IDLE?!?!?! WTH?!
idk for the 7000, but on my 5700X, the best Curve Optimizer I've found was -10... 0 it gets too hot, lower than -15 it loses performance on Cinebench... at -10 it keeps well below 75ºC on my cheap cooler and has the best performance
I see lots of conflicting info on how to stress test 7800X3D after applying the CO offset. What's your take?
I just gave it a shot and set it to minus 30. Nothing happened. Then I set it to minus 40....no issues. At minus 50 it went black instantly. So I left it at minus 30. Temps are a little less, performance is a little bit better. But even at minus 30 do not expect any magical improvements. Temps went down from 85 to 79. Performance-increase of about 2%.
been subbed but thanks for this one did the dynamic 30 will lyk how it goes
Im back here after my BIOS Update. New Bios makes overclocked RAM much more stable so i had to try it. And it does!
I hear you say on a few occasions that with certain settings applied, the PC can crash. What’s the best way to check for stability at certain frequencies? Is there a good benchmark to run?
Cinebench will stress the cpu heavier than any game could
@@Kocainn so it’s good to run this to test the undervolt? How long should you run this for to test the stability? Will one run do or should you do several?

@@Kocainn nice. What level of Undervolt did you manage to reach on your chip out of curiosity?
can undervolting a 7800x3d possibly hurt anything? Like the internal memory controller? The reason I ask is that I recently had to replace my 7800x3d because of a bad memory controller.
I had a -30 on all cores PBO on mine. I would run some stress test and I never had any problems. To be honest I never really had any issues running -35 on all cores either. ITs just the gains were marginal so I just set it at -35. But one day my computer woudn't post to bios. I thought it might be a bad RAM, or MOBO, so I replaced those, and I still couldn't post. It wasn't until I tried replacing the CPU did it just boot up just fine.
I probably replaced the mobo and ram for no reason. I actually didn't replace the ram, I bought new ram to see if it was the issue and it wasn't.
I was trying to run AMD EXPO of 6400 cl32, but I capped the speed at 6000 just because peopel said the 1:1 ratio for the infinity cache was optimal at this speed.
I'm trying to find out what could have caused my CPU Internal memory controller to go bad only 3 months old.
Could it have been running AMD EXPO?
Could it have been running undervolt on cpu?
Could it have been the damn cable mod extensions?
Nope, minor voltage can’t hurt the CPU. BUT, while enabling EXPO many voltages are raised. Those can 100% hurt the CPU
@@ImWateringPSUs I understand. I think I might just keep the ram at stock settings which I think is 4800 m/t. I honestly don't want to go through the hassle of replacing the CPU again because of a blown memory controller. I'm just trying to find out what could have caused it and rule out the other things I've done. On my new cpu, so far I'm testing it at -50 PBO and it seems stable but I want to try other test to see how stable it is.
Many people including youtubers say that is harder to post at more then 6000mhz so i just bought gskill 6000mhz cl32
maybe its not a good idea to go past 6000mhz
probably enabled expo together with a Mobo bios version prior to the max 1.3volt fix. I had the same thing it was really creepy as i was testing out a game before updating bios.
I am scared but I will try it, thanks 😬
What happen? I want to do this but scared haha
@@XtremesTV I did it and have no issues so far. Honestly, I forgot I did this 😂
For the 7800x3d, you do not have the option to manually set the CPU ratios or Vcore. You can only set an offset but you cannot for example set all cores to 48, the motherboards lock this setting for the 7800x3d
What is the best program for PBO stability testing? Cinebench loop, maybe Blender?

Sometimes I think about undervolting both my 7800x3d and 7900xt, but I read horror stories that in the long term (even if all stability tests were passed and everything seems to work well) it can only get worse (instability in specific moments or downtime, etc., which will only worsen the condition of the CPU and GPU in the future) I don’t know what to do, I kind of want to, but I’m scared
Hey brother, with the first method do I have to put the little dash (-) before the I put the number 20 or just put 20?
Just 20. The dash as you call it is already pre-determined by you choosing "negative" in the settings.
I tried to replicate your settings, but the MSI bios are quite different, and I can not find the enhancement setting. Please check how I can do this. I need undervolting my CPU as I will change the cooler system in 3/4 months, so it's better to do it now. I have a B650 Tomahawk MoBo and, of course, a Ryzen 7800X3D.

I have a profile on asrock ripetide motherboard that sets max temp 85 and undervolt -40mv. I dont think it ever crashed. but the CPU has always been used below 50% under any load.
How can I know that its actually using undervolt ? the max clock used is 5050 for this cpu as advertized.
I set all cores to -30 with an PBO on 80 Celsius limit, and my temperature was the same in Battlefield 2042; I just don't understand the point of undevolt for the 7000 series!
I have a 7800X3D, and I don't notice any changes in games; the CPU is running great, and the only heavy CPU game I observe is 70 degrees Celsius, the rest are 59-65 degrees Celsius!
yeah, basically BF2042 sucks and uses literally like 100% of your CPU regardless.
Went with dynamic mode. CPU stays around 65 while keeping 5GHZ. Negative 30 and 85 temp limit. Thanks and subbed !
recently computer has a single click/tick sound in the system once in awhile (i can confirm its not any of the case fan and cpu fan) so im playing around with the undervolting to see whether it works... any idea what can the click sound come from?
another question is can i use both dynamic and static at the same time? for eg, PBO all core set to -25 and thermal limit to 80 + SOC voltage override and i set it to 1.20v does both of these work together or its either or? i also set my maximum proccessing power to 99% to disable the turbo boost of my 7800x3d which can get quite hot. thank you in advance!
I tried negative 18 and it crashed when loading games so I’ve set it to negative 10 and it’s all good to go. Is negative 20 stable for you playing a game?
you gotta really test it , 15 usually works but remember about your 2 best cores. Use amd ryzen to check what these are. You wanna undervolt it a little less. 10 for example compared to 15 since they're really sensitive
Definitely agreed! I usually recommend against per-core optimization because it’s a little harder to test stability, but sometimes dialing back just the bad cores help. I’d say try -15 and you should be good :)
Quick question, im using 7800x3d and i tried doing msconfig-boot- used 16 cores. is it okay to do that? if not how will i put it on default? thank you!
I m using a msi 650 for this and i m not getting the thermal limit option ,there are only 4 option for me those are auto,enabled,disable and advanced,what should i do?
What worked for me was setting it to advanced, which then brought up the thermal target or something similar. Hover over it (make sure it is highlighted) then type in the limit
I got same thing, I choose advanced and directly go to curve optimizer and set negative 20. Didn’t do anything about thermal limit
Thank you!
Nice tutorial, i've done set up the core offset but unfortunately on my asrock b650m pro rs there is no pbo limit based on the thermal degree. I only can set it by wattage, is there any solution for my case?

Not really doing anything for me. No performance, same temps, regardless of me setting it as -20, -25 or -30... What am I doing worng? Followed every step in the video
what would be the recomended coolers really for the 7800x3D? im torn to choose between the NZXT H6 Flow or the Lian Li O11D EVO case wheres in the NZXT is between the Arctic LF3 360 or an Thermalrigt Peerless Assassin 120 or in the Lian Li the Arctic LF3 420 or a Peerless Assassin, (i do get that AIOs might be complete overkill so its more for the esthetics) but a "bigger" AIO comes with the benefit to run the fans alot slower to lower the fan noise and with the VRM fan on the LF3 to also cool the VRM sounds like an benefit aswell?
Thermalright Phantom Spirit 120SE more than enough
Is it -30 offset OR 1.2v and x48 multiplier, or both ?

That’s definitely not stable
Do i need to update my bios to the latest version before undervolting my 7800x3d CPU like this? My bios is currently 1807 and the latest one is 2616 on rog strix b650e-f motherboard. I built the pc some days ago and i have no stability issues so far. My current CPU temps are 45-47 idle(each core is like 30-35 degrees) and like 60-65(MAX) when gaming and having webbrowsers up. The fans are at 800-900 RPM standard curve with these temps.
Out of curiosity, granted I’ve not yet watched the video, I’m at 0:58 but how can something work the same between the 3 ryzen 7000 x3d CPUs? They are made significantly different. Like core foundations of the chips are different. The 7900x3d and the 7950x3d both have two separate CCDs while the 7800x3d only has one. There is a lot of fiddling with the 7900 and 7950 x3d chips (like disabling one of the CCDs)to get them to game at the highest level while the 7800x3d is good to go out of the box. I’m going to watch the video but so far it’s not making a lot of sense how you’d do the same with all 3 chips
Also I truly appreciate you saying if it works for you to hit the like button. Rather than telling people to hit like before watching even 10 seconds of the video
“Good to go out of the box”
Seriously? With 55-60°C at idle and great 360 aio cooler and no changes, no curve optimizer and no SoC change.
Even if you use the 7800x3d, you still have to use the undervolt. I use it and package temps drop by 25 degrees. From 65°C to 40°C and CPU temps (not the package) drop from 55 to 35° on each core.
Cinebench score has an increase, out of the box the CPU scores 14400 pts and with the curve optimizer and SoC change scores 16200 pts. 😊✌🏻
Very good point of criticism, however it is quickly explained: the overall tweaking can and will be different (disabling CCDs, different RAM tolerance) however as far as undervolting goes, they all share the same architecture and X3D chips have all the same kind of binning. So the voltage curve and the way it behaves is shared
@@jakubpokorny5436 you may get better numbers running an undervolt but you absolutely do not have to undervolt it. I’ve got a 240mm aio and never reach even 80c under heavy load.

@@jakubpokorny5436 so yeah the 7800x3d is good to go out of the box. I put the cpu in and it games perfectly. Sure maybe I could get 10% more by undervolting the CPU but there is other crap you have to do with the 7900x3d and the 7950x3d that you simply do not have to do with the 7800x3d, so yea my point remains, it’s good to go out of the box without screwing with power settings. But what do I know? I only upgraded from the ryzen 5 7600x and got an incredible bump in my gaming experience while having access to all 8 cores. Guess what? The 7900x3d has access to 6 cores with vcache for gaming. The 7950x3d has 8 with access to the vcache.
The 7800x3d beats them both in gaming and doesn’t have to cut out half of its damn cores to access the 3D cache

Improvised RUclipsrs 🤷🏻♂️
Ever since I bought my 7800x3D, I couldn't enable PBO. It was causing system instability, very slow and choppy. It looked like a Pentium 1 and my temps were at 80+ idle. But for some reason, by enabled PBO with 80 level 3, curve all core negative 20 and it worked
U need to try 1 core by one core , and see which one makes a problem , takes time but its way better than like this on all cores .
Worth it for a 5600x3d? Can't seem to get it quiet under load at 1440p.
For the 5600X3D take a look at my R7 5800X3D video (in my CPU undervolting playlist) and copy the settings exactly :)
What if I only have PBO advanced? Do I only put the offset to 20 and be done?
Edit: the only difference with this setting is that it doesn’t give me a thermal level selector

Grazie! Col 7800X3D il problema non c’è mai stato perché ha solo core X3D. Se hai il 7950X3D, allora si. Tutt’ora. Ci sono dei tool per sistemarlo ma bisogna farlo per ogni gioco
Buddy, on my Motherboard (asus rog b650e-e gaming wifi) with 7800x3d i can go up to negative offset of 35/40 in the curve optimizer without crashes...good or bad?😅
On CPU SoC Adjust i've seen lots of people, including you, say 1.2V, but mine is 1.020V on default?? Checking right now on BIOS and HWinfo and you go to motherboard section, CPU NB/SoC and it shows 1.020V...
Is undervolting really necessary? Complete idle at 45C. While watching youtube videos its about 55C average. Gaming 60-82C usually in the 70's at least?
Haha saw ur comment while benchmarking on cyberpunk
My shi crashed tho, im trynna undervolt my gpu.
@@southwestwindwhat gpu do you have ? have you recorded the maximum frequency while it hits a certain hotspot ?
Have you recorded how much voltage is being drawn at said hotspot & frequency ?
@@silfrido1768 3060. Yep i have it dialed in finally! Now to undervolting my cpu 😭
@@southwestwind for ampere go -300 on the core always. Since you have a 3060 just go with 850mv at 1925-1930mhz & you will see an improvement.
you will have a static clock speed that doesn’t decrease because of the offset on the core + undervolt.
Is it possible to install CPU soc -1.12? Is this normal?
Ciao mitico e complimenti per il canale, sei top! Comunque senza pbo enhancement ma advanced con curve all core/negative e -30 più altri vari set che non sto qui a scriverti perchè sono diversi ( tipo IOMMU disable ) il consumo in idle sta sui 37/38 W, con chrome aperto anche picchi di 42 . Invece con il bios a stock stavo sui 22 W ma temp più alte. A te risultano questi consumi? penso sia normale per il 7800x3d vero? 🤔 Grazie
Intanto grazie mille! Andando solo di negative PBO offset non ci dovrebbero essere risultati negativi sul voltaggio in idle. Attento a non aver cambiato lo scalare della curva del PBO oppure qualche setting del risparmio energetico, comunque un consumo idle medio si attesta intorno ai 25/30W, dunque i tuoi valori non sono troppo distanti da quelli che ci si aspetterebbe, considera anche che ci può essere qualche processo extra che gira in background!
@@ImWateringPSUs grazie a te, farò altri test, considera che a stock se non ricordo male stava sui 22. In ogni caso la config di adesso è stabile a -30, sono vari set se riesco te li elenco qui sotto appena posso… lato temp va da paura, meno lato consumi in idle
I did only the dynamic way. Which I find is more stable for me. I set my curve to -30 (-40 was not stable). Now i see the clocks reach 5Ghz regularly, especially at lower % utilization. My 0.1% and 1% lows have improved as well. Power never exceeds 60W (stock would reach 60-70W).
Lower Temps, lower power usage, better performance. Why not?
Thanks for your help!

What kind of cooler do you use? Have the fans become quieter after undervolting? I just purchased the 7800X3D and oh boy my 360 AIO is like a jet engine at times.
If I do PBO can I still lower the SOC voltage down?
Sorry for bad english i dont understate good. Do i have to do and static and dinamic overclocking or i can to do only dinamic?
Only one

I’m really happy it was helpful! Thanks a lot for taking the time to leave some feedback :) Consider subscribing if you wanna support the channel!
Hello dude, can you help me with this CPU? I`m literally "don`t open bios and use your CPU", but i bought 7800x3d and found your video, so: am i just need use curve optimizer or after curve i need downgrade Soc Voltage too? Sorry for my bad English, i hope Google translate will help you understand me bro
Just curve optimizer is gonna be fine! But consider subscribing to the channel :)
I need help please, my MOBO is an ASROCK B650e but I can’t find those options (multiplier and core voltage) please help me
Update your bios
I can't find the last option (CPU clock multiplier). I have the ASUS X670E-F mobo
I don’t have the option for Thermal Limit in my Asus bios. I only see PBO Limits, PBO Scalar Ctrl, CPU Boost Clock Override, and Platform Thermal Throttle Ctrl. I’m guessing it’s not the last one since you have that as well.
Never mind there seems to be two PBO locations. One in the Advanced section and the other in the Ai Tweaker section. The one in the Ai Tweaker section shows Thermal Limit as well as the Enhancement PBO setting.
The thing is that we can only set the thermal limits only 75/85 not 80
@@MrGordi320 I was able to set it to 80 but for me it was Level 2 instead of the Level 3 shown in the video. I have a Asus B650E-F motherboard so it might be different for you. Set it to 75 or 85, there shouldn't be an issue since I don't think you'll be reaching those temperatures anyways if you have the Curve Optomizer set Negative.
@@MrGordi320 To enter Tweaker section you have to be in the Advanced Mode view. When you enter the BIOS you'll probably be in the EZ Mode view, at the bottom right you'll see Advanced Mode. Either click it or press F7 on your keyboard. From there you'll see the Tweaker section at the top.
Hello u have a video with 7800x3d and Msi B650?
So why not cpu offset voltage and curve optimizer ? Stay with soc voltage under 1.3v and you should be save, this is what amd said.
You can do both methods, as you please :) I show them in the video all and you guys decide which one you prefer
I had mine hitting low 90s which isn't safe at all, it's max is 89c. For productivity it was unusable, since anything over 80% usage caused it to get to hot. I've got a thermal limiter and the PBO settings on now, so it won't go over 80c and still performs just as good. It's concerning to me, I got a massive case, with a 360 X73 AIO and both my 5900X and 7800X3D would get real hot and we able to be undervolted quite a bit without a noticeable performance loss.
I got this cpu, when I am watching RUclips on Chrome browser, temps spikes from 40-65 up and down. Do you know why?
This might actually have something to do with your cooler/fan curve as well, but undervolting as shown in the video would definitely help!
I face exactly this problem, it is really weird, while gaming I never went upper than 55, but on chrome easily 64, with 71 at worst cases(this is my temp spike while playing cyberpunk at max graphics in every aspect), it is ridiculous having same temps on cyberpunk and on a web browser
@@luishiji This is just a shot in the dark, but maybe hardware acceleration is active on the browser?
@@luishiji Any fix?
same here
I didn't understand about 47, 49 help. you talk about the clock 4.9, 4.7 ghz ???
This method will also work for a 5800x3d -30 on all cores. If your motherboard has pbo tuner I set mine to ppt-100w
tdc-75a
edc-100
This Will help with Lower temps and keeps the cpu from thermal throttling…..Happy gaming yall
Yes, 100%! Great settings :) I also have a dedicated tutorial for the 5800X3D wirh a static option, for those interested
@@ImWateringPSUs you explained this method very well. super easy for anyone looking to Undervolt the CPU and save on heat/and to have better performance. keep pumping out the vids bro. also the Undervolt for the 4090 video was spot on my 4090 (MSI gaming x trio) runs so much cooler now ty for the tips...Happy gaming !
@@Brandobandito Thanks a lot for the kind words and support, really. It means a lot to me, I'll keep at it!
