Thanks you so much this is gold, I had trouble setting up the task scheduler. Your way is so much easier.

Yessir!! Thank you for this guide. Managed to get -30 on all my cores stable dropped my temps down like 10-15c. God bless you 🙇‍♂

Great video man, just got the 5800x3d and that PBO2 Tuner is a godsend, your video also is very informative and provides an easier alternative to the whole powershell shenanigans in the guide.

Hi Thanks so much for this easy tweak and startup guide. Could manage -30 boost all cores to 4442 mhz and around 78 degrees celcius. Great video...to the point

Awesome guide man, just got my 5800x3d today and want to keep her cool as possible, helped me soo much! Keep up the good work!

Perfectly explained and nice shortcut tip! Thank you very much!

Just followed your tutorial tonight and totally blown away with the results. Was getting 90c in cinebench r20 and cores only going to 4.250. After a - 30 reduction, I'm now max 80c and getting much higher and consistent clocks. Biggest difference happening in games as I'm seeing even bigger temp reductions. Before I was starting to consider a new case, reapply paste or even buy a new cooler but now super happy with the results. Even noticing a reduction in my gpu temps since the change. Followed your guide to get tuner to apply changes on restart and all working fine for me.

Just picked up the 5800x3d and finding this guide has made all the difference under volting this CPU. Thankyou!

Just wanted to say thank you! Greate info!! :) Have a good one and keep the good work. !!

Sick video tutorial how to use this app , works flawless for me till now . Huge thanks !

keep it cool, like Chris 😎 love the vids as always.

This video is very helpful, managed to drop my cpu temps by 4C on R23, clock speeds also increased. I just upgraded from the 3600 to the 5800X3D and the temps shocked me hahaha. Thanks !

Amazing and helpful video. Just upgraded from the 3600 model. I was under volting and curving via the bios. All core curve neg offset -30 Voltage under volt offset I have just got to 0.206mV. It was hitting 4.45ghz on cinebench R23 testing and with the latest test, the hottest core touched 61 degrees, the rest were under - I am using a Artic Liquid Freezer II AIO.

Thank you!! i have a Kraken x3 240mm AIO and prior to UV was avg. 75c. some days lower some days higher, after using this i've been running about 63c-65c and no noticeable change to performance!!

Thanks a lot for this. I was gaming for a while and my 5800X3D went up to about 85C on an air cooler while stock. I knew it ran a bit hot but this was a bit uncomfortably hot for me. The glass on the side of my case was extremely warm to touch (running a 7900 XT with it). My 3600X used to only go up to about 65C under load. Using your undervolt technique at -30 in the same game (Days Gone) my CPU only went up to about 73C with the boost at 4450 MHz. This is a huge temp improvement - I was even considering going out and buying a bigger cooler but that seems unnecesary now. Thanks a lot for the tips!

Legend, just got my chip last month and I seem to be using it at -30 at 70c/80c ish right now, any crashes I will try -20. Thanks Chris

I was not able to get the auto startup to work but the rest of it worked now i dont have to input -30 everytime i start my pc cheers for that mate gonna sub you for that

Thanks for this, very helpful and i got stable at -20

Signed in just to give a like and a thank you for this great and convenient video.

Thanks mate, very intuitive video.

Thanks for this, great guide great results.

Right on dude! You are fighting the good fight. Thanks.

Thank you. This vid was perfect. I dont get cooler temps though , which is the only reason I would want to undervolt.

Absolutely awesome! My ASUS B450-F Gaming motherboard has no option to Curve Optimize in BIOS so this works wonders for my brand new Ryzen 5800x3D! Thank you!

I'm just browsing for some gaming tweaks and remember you were doing great work in this field and boom, I have 5800x3d and i'm dealing with high temps a lot now in summer. I'm happy I ended up here. Can't wait to try this, since i'm going up ~90° sometimes..

Thanks for the guide, every thing worked excpt the automation after the restart. Cpu is cooler by 8c , + 100 MHz & - 0.1V @-25 PBO2.

You're brilliant! Thank you! I'm still trying to figure out how to download the file though or unzip it or something... all this stuff is waaay over my head!

Im getting 160-170 fps now in MW2 with this CPU :) Thanks for helping me in your twitch chat for this recommendation

Dropped to -25 all core and shaved a whopping 10 degrees of my 5800X3D and increased all core boost from 4.360 to 4.440 in R23 all while remaining stable. Cheers mate!!!

I wasn't able to get it to start the app up automatically via your provided method, so I fell back to the Task Scheduler method. It was pretty easy to set up and works great. Pushed my luck with -30, and I've seen a significant improvement to thermals during gaming (from ~80-90c to 68-73c) with a Noctua NH-U14s cooler (yes, I know it's not good enough of a cooler, it's just what I had on hand for now, I plan to swap it out ASAP). Thank you for the video, I didn't know something like this existed and would be so simple to set up!

I've been loving the 5800x3d and in Tarkov it absolutely destroys everything. I have a ridiculous custom loop tho. It runs 55 max and sits at 4450 all core. Sometimes 4550 The 7950x3D is gonna be insane. I'm already saving lol

The problem with Curve Optimizer is that the voltage drop effect increases with increased frequency... and the highest frequencies happen at the LOWEST load. I had a 5700X that was stable at -30 all-core for huge multi-core loads, but would crash while browsing the internet - you've got to check stability at very low loads/high frequencies, and I suggest OCCT AVX Large with core cycling.

X3D owners on a MSI Motherboard with recent bios ... they ship with the Kombo Strike setting under CPU Overclocking ... Level 1 is -10, Level 2 is -20 and 3 -30 ... set it here at a bios level and forget about it 👍

another upload lets go!

This is a bit of a necro post, but I though I'd share anyways. the units being discussed in the PBO tuner are AMD PBO curve power units. They are not straight voltage. 1 PBO curve unit is 3-5mv. Therefore -10 offset in PBO tuner is ~40mv negative offset. AMD mandated PBO curve function lockout in Ryzen Master and UEFI. But PBO Tuner can access them. This was done to prevent damage to the cache. It's very touchy to people adding voltage. My Asus board's UEFI will allow CPU voltage offset, so I simply set to -50mv. But using the software, and the task schedule method with wake up from sleep settings is also great. Especially when you are finding the stability limit and making rapid changes, or if you need to set the other CPU limits. It's a great tool.

Thank you a nice guide

Thank you, it worked!

CPUs with crazy caches are something really exciting for low settings gamers!

Thank you so much, I found out my bios did not perform nearly as good as PBO2 Tuner and task scheduler can't even work due to requiring a password I don't know. This was easy and so helpful!

Legend Brotha!

I switched from the 3600x to the 5800x3d. The cinebench temps went from 72 to 87 under a stress test. I’m guessing that’s normal since it uses double the wattage. Runs warmer all around but nothing bad so far

Using msi b450 mobo and with kombo strike level 3 , vcore never exceeds 1.22v but my cooler isn't capable of maintaining temps below 80c .. so applied cpu offset voltage of -0.15 , now the vcore stays below 1.1v and power consumption in gaming is below 75w and temp now below 70c really impressed with it

thank you it helped a lot.

Thanks a lot for this. Easy way😇

Nice vid

I’m running a Deepcool air cooler ak620. Had it on my oc 3900x it would get up to like 75c. Now with the 5800x3d the hottest I’ve seen is 63c running stock settings. Using mx-6 thermal paste. It idles at 29c. On an x570 aorus elite I’ve been using for 3 years.

im getting higher boost clocks with -30 setting. boosting to 4.5GHZ all core. everything seems stable. thank you so much!

Managed to shed 5-10°c from just a -10 on all cores. Much more comfortable with pushing it more now

b Brooo u saved my life xD tnx a bunch!!!!

Thanks for the advice. It looks like I'm able to get away with -30 even. I'm not really seeing lowered temperatures, but it's clearly boosting higher.

Amazing 🤩

thank you GOAT!!

the reason idle voltage can be an issue is the idle voltage can drop to low to keep the cpu on. If you want to go for a heavy undervolt and your say stable at -30 under load but blue screen on the desktop id reccomened high performance mode to lock your clocks high all the time

im glad that i can do it in bios :)

On MSI board you can do it from the BIOS level, I set it to level 3 which is -30 and been working like a charm in CB23 15050 points in MT and 1500 ST. Also from my personal exprience setting PPT to 115, EDC 75 and TDC 115, lowers temps, voltage and score stays the same. But those you have to set in PBO2 Tuner, since in BIOS only have option to limit PPT, no other limits. Would been nice to see how to automate also setting limits.

Really love this video and this application. Running my x3d at -20 all cores helped with thermals. But my problem is pbo2 tuner always requires the windows admin security pop up so it won’t rin in the background for me. Is there a way to overcome it for just this single app?

Not running on startup for some reason, and it prompts me to authorize that it's okay to run as admin every time, unlike in your video. But....I did learn how to make the shortcut, so that's super helpful!

Following your video everything appeared to work except when I copied my undervolt chortcut to the Startup Menu the File did not show in the listing. I'm in the "USER (my name) folder path just like yours. What did I miss? I verified the short cut is reducing my CORE VID but I am still hitting 90c almost immediately when Prime95 kicks in. It's a new built with a Arctic Freezer II 280. Perhaps I need to reseat the cooler?

Great video thanks mate! I turned on Kombo Strike Level 3 from my MSI bios when I first got this chip. And now when I open pbo2 for the first time it already shows -30 on all cores and says "Nothing to apply" when I click "Apply", so I guess we might not need PBO2 :)

Thanks for you help. -20 and all is fine with my 5800X3D. Except for 1 thing. It refuses to go pass 4.45ghz one a single core even with just stockk settings. totally impossible to get it higher clock.

Thanks!

only installed my 5800x3d yesterday..was upgrade from my 3800x...my idle temps are 26c and when gaming the temps are under 65c..halo under 60c the only games that pushes my cpu to 70c and over is battlefield 5 and battlefield 2042..im running the chip stock and havent undervolted yet as think the temps are cool enough im also hitting 4.4500mhz while gaming so think i must be lucky? hopefully it stays running this cool as like i say, its early days. Great video though, i know where to come should my temps rise for some reason :)

Thankfully many ASUS motherboards now support curve optimizer in BIOS. For my ASUS B550, I clicked the following: - Ai Tweaker tab - Precision Boost Overdrive - Curve Optimizer Then I set the three boxes to “All Cores”, “Negative” and “30”. Perfectly stable, dropped temperatures and improved performance of my chip, but your mileage may vary.

5% more perf with cinebench and 10c cooler. this worked for me.

I did -30 on all right off the rip and have no problems. (This is also having Kombo Strike on Lever 1 in my MSI board BIOS for max OC setings) Rendering I noticed a good 8-10c difference and gaming a good 9-12c lower.

Finished at -30, everything below gave no benefit. What's interesting, going -10 resulted in slighty faster clock, but +10C in CinebenchR23. Thanks for tutorial :) Mine sample may be not the best, because i have better clocks CineR23 4150->4400 but with temperatures 75->77C. My cooling beQuiet 360 AIO

Hola, gracias por el video. Event viewer works to see which core crashed, and yes, they pass all tests and then crash watching youtube! not a pro on this by a longshot, have a 5600x trhat i played around with, been thinking of getting a 3D, wrongly thought that it would be as cool-65W type

RAM speed for Ryzen is so important. Anyone claiming otherwise simply doesn't really know what they're talking about. Using PBO tuner, or Ryzen Master isn't always a good idea either. Better to change settings in the BIOS directly, as recommended by AMD themselves and motherboard manufacturers.

@FR33THY Do you mind sharing your bios settings for the cpu? I’ve just got mine today!

been using pbo tuner on my 5800x3d all cores -30 for some months now. It runs amanzingly cool. Testing on cinebench r23, i used to hit around 75C and 14500 score on stock, now i break the 15100 barrier (which is pretty good for a x3d) and i dont even reach 65C... im using a lian li galahad 360mm aio with 6 uni fans push-pull config, so not even a custom loop

Can you make a video about your OBS options?

Thnx!

Why you dont touch the limit window on PBO tunner? I did the -20 but nothing happens. You need to low voltages on limit window 95 65 90 are mine

The content I was waiting for, thank you! I somehow managed to get offsets up to -50 without any failures but I'm almost sure that between -30 and -50 I don't see any difference in voltage for some reason. What do you think about it? Before R23: 85C 14500 pts 1.235 v avg @ about 4.25ghz After: 77C 15080 pts 1.167 v avg @ 4.44ghz offset -30-50 Edit: replaced Air cooler to arctic freezer 360 now Max 68C @ 1.135v This is insane

Thanks a lot for the explanations. I was wondering, can you lower the voltage 5 by 5 ? Or do you have to stick to lower it by 10 ?

I followed the instructions and have the under volt version in startup apps but it doesn’t seem to run upon reboot. Any ideas?

On -20 in PBO2, I'm getting -8C in Cinebench and an extra 100MHz across all cores. "Free real estate".

for some reason the start up shortcut automation doesn't work for me on Windows 10 Pro. The values work when I manual run the "Undervolt" shortcut, but automating it on start up doesn't call the shortcut properly

I guess I'm lucky or is it normal? I managed to set it to -30. I couldn't be bothered to increase the values one by one, so I instantly set it to -30 on all cores and no crashed in a month. The temperatures in gaming dropped drastiscly, between -10c and -15c and I gained a higher clockspeed too so I get maybe 1 to about 4 fps more in games. The results are insane.

I have it set at -20 all cores boost now 4.450mhz and temp at 78c, before i hit 90c like a joke, cinebench r23 now 15045. the only problem is i cant make it auto start no mater what i do. Anyway good video thanks for the info. i have now tried -30 and r23 is 15105 repeatable continuously, in the table where the -30 filled in on the second option there is a single thread speed , is it possible to change that number maybe to 4.7 GHz instead of 4550 GHz?

Hey Chris or anyone else experiencing the App not running at Startup? I put the Shortcut in the Windows Startup folder & the app even shows up under my Startup Apps in Task Manager. But every time I restart my PC PBO2 Tuner does not run. I created the shortcut & edited the target in properties the exact way that Chris does with spaces between the -30's & 8 of them. Anyone else having this issue? Lastly, Chris, great guide & Thank you!

-30 all cores, stable so far. Your method of automating it didn't work for me for some reason, but the task scheduler one works like a charm and isn't that complicated to set up.

Seems like an AIO on this chip is the way to go for sure btw don’t you think AMD Eco mode is just an all-around easier way to go

@FR33THY So it works only for restarts and startups from being off. However the same argument does not work for wakeups from sleep, I tried to add a "At log on" trigger but that does not work. Any idea?

Puting a shortcut in the startup folder works great at boot, but the undervolt still resets after sleep/hibernate. The only way to have it applied permanently is to do it the Task Scheduler way. It's a bit more work, but it ain't that hard.

13:50 Is there a way to set target for the Limits tab for the PPT, TDC, EDC, MaxBoost, Temp, and FIT Scalar?

My sweet spot was -19 all core, 4,442Mhz, and 74C. I use the Arctic AIO 280mm cooler. The Startup folder method didn't work for me. For some reason, it wouldn't include the arguments from the shortcut and just run PBO2 tuner.exe. So It wouldn't apply any offsets. I wound up just using the Task Scheduler method. But thanks for a good tutorial.

nice video and nice work around to set curve off set auto when booting into windows, is it also possible to auto set limits from the PBO2 tuner (PPT TDC EDC limits)

Hello men) did you test effiencymode in win11 in taskmanager?

this is great, but I can only seem to do the manual mode. My start menu does not have the folders that are visible on your start menu. When the programs are placed into those folders they are only visible if I manually go into those folders. They do not appear anywhere else. When i make new folders they are not visible in the start menu.

What kind of clock speeds are you gaining? Msi has kombo strike which undervolts. But i don't gain any boost frequency.

this seems like a great way to test CO values on the fly while testing. but wouldn’t it be better to set it in bios once you find stable per core PBO2/CO values?

Hey Chris! Do you think it would be worth it to wait for 3d zen 4 chips or go for the regular ones soon? Only play CSGO and higher 0.1% lows>average fps

I have just got 5800x3d too for about 2 weeks ago and run blck overclock on bios 102 to get 4.54Ghz all cores/multicore and one core get up to 4.6Ghz something feels nice to have. run PBO negative curve -30 and Vcore offset -42mV to get 130W package usage as higest with 77C temp. goes 1.218Vcore when all cores are used to max otherwise flexing from 0.888Vcore/1.156Vcore. just went from r5-5600x clocked 4.96Ghz PBO and hit +140W was hard to cool down. way to powerfull for my rtx 3070 clocked 2100Mhz core and +1000Mhz mem ...... could even go even lower on voltage but when I do that my sound card build on motherbord get crashed and I get my headset on max volume with static noice almost pop my ears and will never war headset on testing overclock !

Hi freethy I saw another tech tuber do a test on rust on the 5800x3d and some other games and saw that the lowers where at 60 fps with a 3090 ti do you think this is because of the multi chip die and that intel is a lot better than ?

I added the shortcuts to start menu programs and startup and it shows up but when I restart it doesn't run the program. Any idea why?

Hey mate Thanks for the great tutorial. How come your CPUZ says its a 5800x and not a 3d?

Hey Chris, how do i add my set numbers for PPT TDC EDC limits in the autostart-shortcut?

I am totally confused! I wanted to undervolt purely to lower temps and to keep the same performance, maybe better. Less heat, less power, cheaper bills :). My chip rarely goes from mid to high 40's, dipping ever so infrequently into the 50's. I play WoW mostly, but even on more intensive games, I get little difference. 78 degrees!! I do have a Corsair 360 rad fitted, but even so. Have I struck the silicon lottery? Even running OCCT I barely go above 68.

hey brother nice Video can u make a Video about i9 12900k and show how to undervolt it this temps makes me crazy mainboard is asus z690
