If you want to save the limits in the task scheduler just type those values after your core clock offset values. Lowering the limits let me keep same performance but reduced cpu temp by 20 C
I'll give this a try, mind if I pin your comment for people to see as this is really helpful if it works as you mention 👍
If you could please let me know how you entered the values? I'm having trouble getting task scheduler to run with offset and values both being there.
@@Beefy-Tech I reduced my PPT, TDC, EDC limits this is what helped reduce my temps. 8:54 in the arguments, you type in your curve values for each core. That is 8 values. Then you type in your PPT, TDC, EDC and then 0 (0 means don't change any of the other fields like MaxBoost Temp LImit, FIT Scalar)
So for example mine looks like this
-30 -30 -30 -30 -30 -30 -30 -30 95 80 100 0
PPT = 95W, TDC = 80A, EDC = 100A
By reducing my PPT, TDC, EDC limits I saw almost 20C drop while gaming, no performance drop and actually hitting the 4,450 Mhz (before I woudl only hit 4,100 Mhz)
@@Beefy-Tech absolutely, it's not letting me edit my comment with me explaining how I entered the values, I responded below, but feel free to pin my response as well
@@mannyfresh7065 gotchu fam, I had some issues trying out the numbers yesterday and I input 120 75 110 after the offset, but no luck. Imma attempt to input 120 75 110 0 in a bit and see if that does the trick
1 year later and cpu has been performing the same as day 1 with the same temps, just coming back to say how gratefull I am for this vid, helped me out so much
-30 offset on all cores 132W 85A 130A configuration has maximized my effective clock speeds while reducing temps by over 20 degrees celcius. Was hitting around 83c in far cry 5, now im at a very comfortable 62c after a long gaming session. Ive combined this with Fan Control to make the most out of my case fans and it has done wonders for my system. Thank you very much for your explanation and help
Edit: 127W 80A 125A -30 all cores, stable for 2months now
Nice. What cooler do you have for your CPU?
@@Pazo139 an old scythe mugen 5 rev b
@Karel Leet That's really good, even better than me with my 240mm AIO. I will redo the paste with a better one. I did -250mV in MSI bios as I couldn't really get PBO to work for some reason. I end up cruising in the low 70's at most with gaming so far. However, stress testing with the likes of Cinebench R23 makes it reach 90c albiet slower than stock voltage.
@@Pazo139 I had terrible temps on my first paste, single dot method, then i reseated the cooler and i had spread out the paste a bit and it lowerwd the temps by a few degreees aswell, hope you can get pbo to work its really worth it, higher clock speeds + lower temps
@@karelleet Update; I redid the paste with my newly received Thermal Grizzly Kryonaut and spread the paste on the entire chip. Before that I did the dot method in the middle. Turned out I didn't put enough I guess. Because it hardly covered half the chip lol. Now my temps are great maxing 55c on Cinebench R23 with my continued undervolt. Also what are we referring to by higher clock speeds? Higher than 4.5ghz boost?
Great tutorial, thanks! Improved my multithreaded Cinebench R23 score by over 700 points. All cores boost to max now on my 5800X3D.
Hey man! I just want to thank you, I was searching for this for a long time! Your tutorial is the best and very easy to apply! Thanks again!
Thanks for the straight up easy to follow guidelines. Worked perfectly right away. My mobo doesn't have curve optimizer or pbo. This worked a charm!
Thanks so much for this tutorial, went from 80-90 degrees to 60s under full load. Amazing.
Super cool to see fam!
@@Beefy-Tech Help me PLEASE : PBO settings changed (getting defound values) when waking up from sleep/hibernation . Anyone how to fix?
Deserved like, another video or two did the same thing but missed two key points and this video addressed both and allowed my system to run the task scheduler as needed. Thank you
Thanks a lot, I had an 240mm AIO for my 5800X3D and I didn't see a lot of improvement compared to my tiny aircooler it was still reaching 50-60 degrees idle now it's at a happy 35-40
That's good to hear!
So happy I stumbled onto this video. Thanks for making it man.
Gotchu fam, hope it helped👍
Thank you So much! for the indepth tutorial, was able to get my hands on -30 x8 and PPT 100W TDC for 70A EDC 100 temps 62 top on OCCT with 360mm AIO constant 4500MHZ, so much cooler and so much preformance gain thanks for the task setup i had trouble with that!.
Geez thanks man! I just installed my 5800X3D today and the spikes from 46 - 72 are crazy and almost instant just on processes like opening chrome!
Dw it's completely normal for it to do that on startup. While it seems like weird behavior that's how they all function, I too got jumpscared by that when I first got in many months ago xD
@@Beefy-Tech will undervolting help?
Thanks for such a clear guide, worked perfectly.
A month ago I did this and set all core to -30. Did many stress tests and games and never had crashing. Saw a nice boost in clocks it’s now at 4.45ghz stable even sometimes when all cores are being used. It’s higher then the clocks I was able to squeeze out manually from my previous 5600x. And my temps are looking juicy. Usually never goes above 75c in games.
When you get a chance please reply, new to the pc world and finally built my new pc yesterday. I did the -30 like you did and my max temps just sits at 78-79c max 100% load on cinebench. Is that bad? Multi core score was 15024
i can never get my 5800x3d to 4.45 ghz max. Stocked its around 4250-4350. With pbo2 i get 4.42 maxed -30 all. I guess that'll have to do. My temps are never that high anyways with a krakenz63 i get around 60-65 at stock anyways... Edit: NVM task manager says cpu is at 4.42 but msi afterburner in game says its maxed 4.45...
@@SSSx30 nope that’s really good!
@@Excal123I got the same setup and my temps are 85 on cinebench. Only 4.3 after the - 30. Am I missing something? Did you redo the paste on the x63? Is it loud also?
@@DanielSmith-ys3ov that's really high temps. I've never had my temps over 80 not even close probably the highest I've seen recently was 72 and that was rare idk. I did redo the paste because I had to put the cpu in. Ambient temperature around here has been cold lately too so that might be part of why mine is lower I shall see in the summer months that should bump it up a little. Not sure what cinebench is as it might stress it more I'll have to see. My z63 also seems quiet too.
Thanks for this! Im not completely clear how the curve offset values work, havent messed with OCing much at all really in over a decade, but was able to get my 5800x3d set to -30 on all cores wirh 120W/75A/110A, simply matching your settings on limits, but it ran the OCCT stability test for about 7 minutes before i stopped it, seems pretty solid!
I had already set my infinity fabric, memory controller, and memory speed all to 1900mhz
7 mins is not stress testing lol
OCCT has several stability tests with different loads and 7 mins in barely goes into the first one
-25 working well for me, thanks for the quick and easy guide.
Try please -28
works for my 5800x3d, from 49c idle to 37c!!! Thanks a lot bro. Cheers.
and i even applied a custom alert for every time PBO2 values have been applied.
Awesome to hear fam!
My 5800X3D is 32c at idle with a dark rock 4 air cooler and stock settings...........
Awesome video! really glad you included how to edit after the task is created makes it easy to use for beginners. Went from 80+c to 75c in r23 while boosting to 4.45G all cores most demanding games (hell divers 2 was making my ac work overtime:) dropped 10/15c to around 60c with setting at -30 -30 -30 -30 -30 -30 -30 -30 120 75 110 0. Best way to tame the spicy 5800x3d if your MB is locked curve like my ASRock x570. Air cooled with Thermalright Peerless Assassin 120 SE in a Fractal Torrent case all fans now running at 25% instead of 50 to 60%.
I feel blessed that my MB bios lets me set my PBO2 curve so I don't have to jump through the task scheduler hoop. This video did help me tune my curve better tho and thank you.
My 5800x3d managed -30 for all cores. Seems stable after an hour of OCCT CPU testing and several hours of gaming. Thanks for the video!
same with mine using -30 on all cores for like 4 months by now , 0 problems and manage to drop the temps by almost 11 degrees with this undervolt profile.
Wonder if i can go lower then this , and try -35 or -40 ? :)))
or -30 its the limit max ?
@@sorinpopa1442 -30 is max, if u go lower, than nothing happens
@@HybOj i.c ya thought the same , didnt saw anyone online that went lower then -30 yet ^^
The 5800X3d is a good binned part because of its Voltage limitation due to its V-Cache , most 5800X3D will work with - 30 which is already the maximum , higher Numbers have no effect at the Curve Optimiser , i would choose this as the starting point and only if there are Problems i would reduce the value , my 5800X3D works since months without issues at -30
It depends what bin you get. You have really bad bins that cool really hard even with proper undervolting. I had the bad luck of getting one which can barely be cooled with an aio 360mm - under cpu intestive workloads and cinebench on stock temps rise to 90°C+, with pbo 85-86° with fan rpm's close to 2k. Optimum tech recently bough a second which was also a bad bin - very hard to cool compared to his first cpu.
@@mesicek7
Its the first Time i heard something like that with an 5800X3D , here is an CBR 23 run of my 5800X3D ruclips.net/video/0jkzGVoQs5w/видео.html
In the right upper Corner you see the CPU Temp is at 77-78 C (celsius) with an Power consumption of 80-81 Watts , of course the Temp will go up a bit if you run cinebench for a longer Time , but you get an Idea how it looks like ( it depends on You Tube how long it takes to be aviable in HD )
The key is the Curve Optimiser at negative 30 , lower Power consumption = lower Temps even at full load .
@@MK-xc9to Well, I can be included in @mesicek7 case, I'm at -30 using Arctic MX-6 and AIO 360MM (Push and pull) and at CB R23 it is hitting over 81 which means it is dropping frequency already. I will be trying to use liquid metal as my last option. Pump is at 2700rpm, fans at 1600, no luck here..
@@fernandosbtech Well ... , thats my CB23 run , its ~ 400 CB lower because the record uses a tiny bit of CPU Power ruclips.net/video/0jkzGVoQs5w/видео.html and the Fans are far from full speed , of course it depends on the Room Temp as well , its 18-20 C by me . Besides , normally , Games do not use the CPU as hard as Cinebench does = the CPU Temps will be lower
I use a Alphacool Eisbär , which is a expandable AIO , Full Copper Radiator
I buyed it with a 240mm Radiator and added an 280mm Radiator , the 2x120 Fans blows hot air out of the Top with help of a 120 mm Fan at the Back , the 2 x 140 mmm Fans blow cold Air into the Case from the Front
@@fernandosbtech I just got my 5800X3D and have similar problems. I use a 360 AIO form Alphacool and liquid metal, I am not able to get the temps under 90°C in Cinebench R23. I also tried the same PBO2 settings shown in the vid, but still the same. It is driving me nuts. I first thought its a problem with my cooler and alreade dismounted it and reaplied some liquid metal to be sure, but did not make a big change.
Tip for 5800X3D owners, if you're still getting toasty temps, you can combine an offset in the BIOS (offset of the VCORE, so FE -50mvtt) with PBO.
Seeing as the absolute clockfrequency isn't very high, -30 usually isn't enough to drop the temps. So I use a -50mvtt offset, then set -15 PBO2. Dropped temps from 75 to 65 and im hitting the same 4450mhz.
Thank you sir, I bought this chip for better performance in dcs vs a 5600x . Initialy I was not impressed but with tweaking I got around 25 fps uplift.
Your settings worked perfect for me, thanks
This is GOLD, as well as the fixed comment!
Great video my man!
Thanks for the video bro 🔥🔥✌️
this video is exactly what i was looking for
Glad to hear fam!
I'm amazed man.
-25 all core, set PPT 135, TDC 90, EDC 135 and now I'm maxing out at 75c (on air cooling) and boosting to the 4550 100% of the time when stress testing.
That's the beauty of undervolting! On X3D cpu's (5800x3d, 7900x3d, 7950x3d) the results are always nuts. Lowering those Temps leads to best performance🙌
With the ppt tdc and edc, how do you set that automatically in the scheduler?
What mobo you got mate?

@@transcendtient Nice, ive got the Pro v2(b550). What has gaming performance been like with those settings? cheers.
Can be done, no problem
-30 everything went perfectly... thanks saved !
Glad it helped fam 👍
thank you man for the video, followed step by step and now my 5800x3d performs really well on both 4k and 2k without surpassing the 70 celsius on many games, average 63 degrees celsius, before this the average was 72. thank u
Awesome to hear that bro!
@@Beefy-Tech hi man, yeah, im really grateful, however, was just taking a quick look to more info on the pbo tuner, does it have any sideeffects, read on some random reddit post that doing this has its disadvantages such as throwing in more current and voltage to the cpu for better temperatures and that that might in time cause damage to the cpu, have you read anything about this?
@@MultiOlimac that wouldn't make sense because with PBO2 you are using less current and voltage to achieve the same or better frequency 🤔 only time it can cause damage is if you indeed use more voltage then safe, but the pbo2 tuner app can't apply positive voltages, they just won't register at all, it can only apply negative offsets to 5800x3d.
@@Beefy-Tech I’m such a dummie, that’s right, that’s why it’s called undervolting. One last question, could you please lighten me into what the offsets actually mean, for example, -20 means 20watts less on a specific core or what does it mean exactly?
@@MultiOlimac so it's-20mv, which stands for Millivolts. The offset changes the target voltage required to achieve a maximum frequency. Let's use the 5800x3d as an example. It's target frequency is 4.45ghz and it uses 1200millivolts (1.2volts) to achieve 4.45ghz, if you undervolt by -20, it'll use 1180mv (1.18 volts) to achieve that target frequency, while decreasing temps as a result of lower voltage.
This seems like a great tool to test find your stable values....instead of having to run this task scheduler seems easier just to adjust your bios after you find your stable values.
Thank you! Literally minus 20 degrees via 15 minutes of tweaking. Works better than a water cooling chain :D
i wonder, why amd isnt doing this out of the box...its so weird
@@yoool7137 I guess, that there is some significant percentage of cpus that can not handle that. That would mean, that more cpus they produce would be defective.
It is all about economics I believe
Awe-freaking-some. Thank you!
using at -30 with my 5800x3d for 6 months, and never had any issue, the temps never go above 64c in games with arctic air cooler! its just a must to do for this cpu. (my rx 6800 is stuck on 99% usage in every game)
How did you do it
@@talal5716 watch this video.......................
Thanks, simple and fast, perfect.
I appreciate it man this software is a lifesaver
🤝😎
hmm my 5800x3D has never gone above like 70C in any stress test, infact I had thought this entire time it was one of the coolest chips I have ever owned but I am trying this currently to see what I get out of it. Thanks for the video and I hope I can gain something from it :)
This did absolute wonders for me. I got it all the way to -30 stable, so i guess I got a good bin. I'm sitting at 4.4ghz 80c at 80 watts. I know that the temps are still a bit high. I'm still using my hyper 212. I know I need to get a better cooler. I wasn't thermal throttling before, but I didn't like it sitting at 90c constantly.
Edit: I actually changed my best, and 2nd best cores to -25 -27 to get better performance.
Thats because you had "clock-stretching". Few CPUs can go -30 all core without nuisance of "clock stretching" ruclips.net/video/jTkDqARDkGg/видео.html
@Coco Sloan this doesn't seem to be the case for me. My effective clocks are almost all the same. My performance has also not seen a hit, but only gains. I did set my fastest cores with a different offset. However, my other cores seem to be fine.
@@DubCity Now maybe its fine - but while tuning and setting -30 all cores - you can observe that effective speed of all cores are lower than expected. That's because one core is getting to low voltage ,drops in frequency and takes all the other cores down with it , and needs to be adjusted higher in CO. Watch the video and check you do everything right .
All I'm saying is there are maybe 5-10 CPUs in the world that can do -30 all core without issues !
Same here but it's a 212 Evo, with be quite silent wing 4 fans for push pull combo, easily handles this cpu with -30 which I was able to get myself 🔥 usually chills around the 60s under load with gaming
even with a fuma 2 it is hitting 90C, using the pbo2 tunner, now it is on 80C (though I'm on an ITX build -closed)
thx! i have -30 all cores and running 65ºC max with NH-D15!
yeah 500th abo i was :) :D nice vid.
Sweet xD welcome 500th sub!
Very effective Thank you. I guess im lucky, -30 all cores, -20 all limits. 4.45 all cores. 73watts. 58degrees (360 aio) and stable.
Very solid! Funny story this video is one of the few videos I posted months ago that still holds up well in terms of the quality of the tutorial...just wish I knew how to apply the limits back then, but the community figured it out in the meantime xD
@@Beefy-Tech I was already pleased with the gaming performance having switched from a 5900x, and this is a Tinkerers icing on the cake.
Thanks for the help. I ended up doing your settings and things worked great. Then searched more info about how to set limits to scheduler and found out even better settings in overclock forums with lower temps with the same performance. Just replace values “-30 -30 -30 -30 -30 -30 -30 -30 95 60 90 0”. It just adds 95W PPT, 60A TDC, 90A EDC. Worked like a charm!
I run with -30 now too! I didn't before just out of fear for stability but it was stable for a week so I stuck with it.
And yes I only found out how to input the limits last week so didn't include in video unfortunately but you are right, and your limits are great👍
PS: girlfriend now has my 5800x3d as I moved to 7950x3d, but I input the scheduler with undervolt and limits for her!
@@Beefy-Tech Great! Btw... Your video was so good with step by step instructions. It saved so much time
@@Monsux I'm glad to have helped! I want to make more videos like this in the future in hopes it'll simplify everyone's time with a process that is otherwise not very clear xD.
@@Beefy-Tech Hello ! Put that values in Task manager (PT, TDC,EDC ). But I`m not sure how to check them if they apply directly. Ok, I restart - I entered in PBO2.exe. The -30 is in place, but the others (PT, TDC,EDC ) when I put them manually and click apply - say, "configuration changed". Is like the arguments for PT, TDC, and EDC are not applied after restart. Yes, I put the values in the task sheduler after -30.
@@M4V3RiCkU235 in task scheduler where you have the -30mv line, ull have to type your 3 power limits, then type a 0. Your task scheduler line should look like this:
-30 -30 -30 -30 -30 -30 -30 -30 120 75 110 0
That 0 at the end is important for it to work👍
Thank u sooo much i have temp like 90-92 on normal playing now i have only 76 max
AMITool (if you can get a hold of it) can be used to write the offset values to bios on ANY AM4 board.
I have figured that typing the offset and then values with a 0 at the end does the trick for scheduler to set the limits too.
Great video!!!
nice job man
One thing I think you forgot to mention is when using manual PBO offset, just like with ryzen master on the 5000/7000 series, is you need to validate clocks using HWInfo or even OCCT to check “effective clocks” match your shown clock speeds.
Too extreme of a undervolt with CO, will result in some or all cores not actually running at the clocks it thinks it is. OCCT and HWINFO have this reporting tool for this very reason.
This is important because while the system may be stable, you’re losing performance potentially in cores that need more voltage to actually properly boost under load.
It’s extremely rare that all core -25 or -30 is actually stable in the case, usually you see your best performing cores wanting more voltage to actually boost high enough in low core utilization scenarios.
I used hardware info to verify stability in OCCT bit I forgot to mention it here not realizing that it could show differently in OCCT. I have run -30 and -25 and I yet to have a crash myself, but I imagine its not like that for most people. I am hopeful that if anyone has issues with it they send me a comment so I can tell them exactly of this 😆👍
@@Beefy-Tech stable != Performant. What he's getting at is that you can be totally stable but not gain performance as it starts clock stretching to maintain stability.
Scores are often better with a mild offset than -30 all core, and the cooling solution has an impact on how much offset is tolerable before stretching as the volt/freq curve offset changes based on temp.
So once I get hwinfo, if I set it all to -30, how do I find which core is stretching and boost them? Dunno what I'm doing this,
but trying to learn
@@LaoNinja007 check for “effective clock” anything bc below your set boost for that Core is a bad UV.
Where does this info come from that it's "exremely rare" to get stable performance without clock stretching at -30 on all cores with a 5800x3d? I do not have any issues at all.
Thanks for this video, my 5800x3D run better now (-10°)
Awesome fam!
Thank you, good job
I did the following in bios for my Ryzen7 5800X3D: -30mv all core, PPT88, TDC61, EDC90. In Cinebench i get 15088pts, max temp: 78-80, power consumption 103W, all core boost 4447MHz.
Before when the power setting was managed by auto i was getting 15180pts with 90°C and 126W, all core boost 4444MHz.
dang man, thanks alot!
Great vid
Just wanted to mention a lot of motherboards do actually support pbo2 tuner in bios, but not all of them do. You will have to look up your specific motherboard and check to see if it had PBO2 support in bios!
110w 70a 105a -30, is the best for mine - still not liking the temp - 80c - (but have to be fair as I am on a closed ITX build) and above all the total sys doesn't go above 300W under full load with a 6700xT :)
don't think I can finetune it more...
@@HitSousouK I use 120, 75, 110 if I remember correctly, but yes, the case and cooling matters most here. You might be seeing hot Temps but in ITX it kind-of makes sense, especially with a cpu known to run hot
Asus b550 strix wifi 2 Support it with the latest BIOS. I Set it to -30 all core in the curve optimizer setting direkt in the BIOS works perfekt.
Any clue if mine has it cuz I can't find running the latest bios version, X470 Asus ROG F-gaming?
@@Cheesy1cheese best way to figure it out is if you have "Curve optimiser" in the bios. I'm not sure if you have it but that's what you'd look for.
Thank you
ty for the guide
You don't need to use PBO2 just go into bios and load a saved bios setting from your a USB drive, when you do the OC and PBO will be available to fiddle with, but only until you boot into windows. Any changes you made will be there
bios on 3d vcache chips are locked im pretty sure for OC
subd thanks, will try this out
one year with -30 all core and is awesome.
thank u bro
Yessirr -- 100 - 70 - 100 -30 all cores, 15 min test and its all stable.
Thanks!
You got it fam🤝
My temps in game are amazing after doing -30 and loweder limits. 50-60c in games and boosted my mhz to 4450 maxed when it was sitting around 4250-4350...
Exactly the beauty of an undervolt!
I'd love to know how you got those temps. I've done pbo2 tuner -30 uv and all it did was reduce temps by 6-7°C and im using a 360mm AIO kraken.
My Temps were at most reduced by 5c when limits are applied with a -25 offset with 360mm cooler master aio. 5800x3d's vary quiet a lot in efficiency, so there'll be quiet big temp differences between cpu's regardless.
@@Beefy-Tech I mean how are you even getting those temps at stock settings? Every reviewer got over 75°C under load. What are your temps in cinebench or if you encode a video in handbrake?
@@mesicek7 OCCT is not as heavy as other benchmarks, it's more representative of an ingame all core workload. In cinebench R23 I'm pretty sure it hovers in the mid 70s (75c-78c) with UV enabled.
Start at -30 all-core and use Core Cycler to hammer the CPU with low load/high frequency testing - curve optimizer is most likely to crash at HIGHER frequencies (= LOWER loads).
Also, BIOes now allow CO settings on the 5800X3D, so need need to set up a PBO2Tuner scheduler.
You can undervolt now in bios,just update them.
Is it possible to have the limits change at startup as well? It seems i can keep the curve offset automatically with the steps in this tutorial but id have to manually reapply the limits.
Hi, Thank you so much for making an easy to follow tutorial. My apologies if this has been asked many times before, but I just got my 5800X3D and was wondering what's the difference between PBO2 vs manually changing bios setting vs MSI Kombo Strike? and also, which one provides the best performance with the lowest temperature?
Kombo strike 3 is thought to be an automatic 30 curve offset, but I've seen varying results from it.
Pbo2 tuner you can manually input any offset, and it definitely always works and shows benefits, so I recommend it over kombo strike 3.
@@Beefy-Tech thank you so much
yup use bios if you can, I can't. What a time to be alive you have to research BIOS options now
I bought AsRock X570 Steel Legend, changing stuff there manually, no user friendly automatic systems whatsoever, lucky there's even XMP setting.
I bought ryzen 7 5800x3d yesterday and i set all cores to -30 90W/60A/90A and i got 4.45 ghz core clock stability and only get 60°c
The cooler that im using is air cooling Noctua NH-D15S
Glad i pointed you to this also there is a new bios and you can do CO in the bios now :P Still i have more fps then you at big map im avg. 249fps stable with 169 1% lows @720p 6700xt tested for fun. Your 70 fps drops at rebirth island are strange. Looks like memory oc stutters either to low VSOC voltage / VDDG IOD or to low mem voltage combined with to low tRFC. Im at 149fps 1% lows on rebirth with 219fps avg @720p. 3866cl16 but all sub timings max tuned + 140ns tRFC could do 4000cl16 same timings but to lazy :P Also there is a huge penalty in WZ2 if you have your windows page file turned off. My friend had a problem with crashesh/stutters hes on 32gb ram and i think windows11 turs it off if ur at 32gb. Turning it back on auto resulted in 0 crashes and +20% fps and stutters gone :P
I mean it could be that something is wrong with my Ram timings, I would have to set to default and run some tests which I'll do. I have not heard of the windows page file before so I will check it out and see if it's on or off.
I bought the 7950x3d which I plan to run on 1 ccd with only 8 cores on warzone to compare to stock performance, and obviously upgrade from 5800x3d. With this occasion I'll reset everything to default and redo my ram timings to see if I made any mistakes 8 months ago when I did initial tuning.
It could also be that page file thing with windows 11, but I yet have to test it out.
Also, I got a dual pc setup and new mic and will finally be able to record without FPS loss for best representation of results👍
Thanks for the guide. My motherboard has PBO2 option, do I use this method to find out the numbers and then plug them in on bios instead of applying a scheduler?
As a 5800X3D owner I want to say my temps we're at 90*C idk for what reason I have a good cooler but is this suppose to happen to everyone? Like this I don't know why I felt guilty to undervolt when I shouldn't have to etc
Thanks for this very informative video, it was great. However, it does lead me to a question: the curve / -20 settings start on start up, but what about the PPT, TDC, & EDC settings? I don't believe you went over how to do that on start up. Would be great if you could share or let us know whether or not that's possible.
Yes, at the time I didn't know how to do it, now I do.
When you type your command line in task scheduler, right after the negative curve optimizer settings, ud input your limits, and then type a 0 at the end.
The line should look as follows:
-30 -30 -30 -30 -30 -30 -30 -30 120 75 110 0
@@Beefy-Tech Thanks a lot for this, you're a GOAT
@@Beefy-Tech Had another question if you didn't mind. When you make the Core's -20 to -30, does that mean we are reducing the frequencies of the cores?
@@Swaangin no not particularly, undervolting isn't just reducing voltages, it makes precision boost overdrive choose the same frequency at a lower voltage. Essentially, it'll run the same frequency at lower voltages, which in turn allows it to run a higher frequency at the same max voltage as before.
The 5800x3d caps at 4.45ghz tho so the undervolt doesn't scale past your frequency cap.
Thing is once you undervolt too much, the system slowly becomes unable to stably run the same frequency at a lower voltage, and the only time an undervolt can hurt is specifically when its unstable.
Its not changing any settings for me? OCCT isnt showing any changes when i input numbers in PB02
ty u
LOVE U BROTHER , u help me get 4-5c lower temps and 4450mhz now before is use to get 4300mhz also little fps gain.
i have 5800x3d with - 30 all 8 cores and nothing else i dont change any other tdp or other parameter as roit vanguard mess stuff up , so just use -30 all 8 cores and 4lowertemp and 10 watt less energy , i notice my cpu use 1.18 v
Hey Beefy. Just wondering how much you gained in mw2/wz?
My Temps are pretty good with my 360mm aio and hitting 4.3hz. Pretty happy with performance paired with my aorus 3070ti but all way looking for more. I’m not the best with computers but have learned how to oc gpu, ram and my other CPU’s. This looks a bit more tricky for me to achieve but if the gains are decent I will give it a go. Thanks for the upload.
It hits 10-20FPS more depending on which part of the map I'm on, in game I have render worker count set to 8 and the undervolt makes frequencies sit 200-300mhz higher in warzone which uses all the cores.
@@Beefy-Tech Tnx beefy. I’ll try it out and get back to you with results. Cheers.
@@qubes8728 mind you this only makes a difference if you are cpu bottlenecked. The 4090 I was testing with normally sits at 60-70% usage or less, so it brought it up by 2-5% usage on average resulting in that 10-20fps difference.
@@Beefy-Tech Ah ok mate. Im running a 3070ti with the 5800x3D.so pretty sure im gpu bound hehe. tnx beefy.
How do you add the limits into the arguments? This only sets the offsets if you boot it up, right?
It's not explained in the written format either.
how do you check if the task scheduler is done correctly? I've open the PBO2 tuner to see if the offsets was applied but just shows 0 for all values.
It should open to the offsets that you set. If it opens to 0 it means it hasn't applied correctly.
Make sure you type out the offsets and limits exactly like this
Offset + power limits
-20 -20 -20 -20 -20 -20 -20 -20 120 75 110 0
Just offsets
-20 -20 -20 -20 -20 -20 -20 -20
Any luck getting your infinity fabric to 2000mhz? I think there needs to be a voltage bump somewhere to stabilize it, and undervolting somewhere else to bring the thermals down.
You cab stabilize it to a certain degree... but it's not very consistent on my side. For example cod runs, but it shows a Whea error 2 mins into OCCT. You can change some voltages and Power limits but generally the lower voltage a 5800x3d can run at, the more stable it runs, so 1900mhz+3800mhz ram is far more consistent overall.
@@Beefy-Tech oh sweet, my ram’s XMP is 4000, I dialed it back to 3600 as my efforts to run my infinity fabric above 1800 have all failed, and I think I’m doing wise by running in coupled mode, even though I’m running my ram slower than it can go. My motherboard is top of the line with tons of cutting edge server grade VRM’s so I would think it should be able to squeak a bit more stability out of the 5800x3D. But after crashes at even 1900 I decided to pair down to 1800 until I get some guidance. As this is all new to me.
I got 4000 memory knowing the infinity fabric was capped at 2000mhz and I wanted to max it out, so I’m very interested in how I might be able to make it work. My CPU cooler is a monster so there must be a way.
Can you program TTC EDC etc at boot up also, like create a new action where you write -30 instead you write TTC 110 let's say ?
I ended up doing -30 and 95/80/100. I was wondering about your settings for CPPC, CPPC preferred core and C-state? Mine are on Auto, is that ok ?
Since the values persist after PBO2Tuner closes, is there a way to get PBO2Tuner to close automatically at the end of the startup routine?
Thanks.
instead of the Task scheduler you can also just put it into the Bios and it will always run on startup.
i think that 3d chips are locked, only some motherboards can allow it
Hey, I'm doind step by step to set the PBO2 settings on task scheduler, but it's not being applied, only manually. Do you know what is happening?
our temps are wildly better than mine with a DarckRock Pro 4, where I will hit 90C after about 20 seconds in Cinebench R23. Clocks will be around 4200-4300 throughout a 10-minute run. I will check this out but I doubt I will have the headroom tempswise, maybe? Or maybe that means I really should look into it. I'm completely new to undervolting so I'm just wondering if there is any possibility that one can "lock" their system with an unstable clock, or is it reset every one reebots? Thanks, man.
An undervolt won't be able to damage your system or lock it. It may lead to a crash due to instability, but it won't harm your pc and you can just adjust your undervolt if it were to happen. If you hit 90c in cinebench then def give the undervolt a try, it'll help in games by 2-3 degrees and in benchmarks by up to 5 degrees if you use both offset and power limits.
@@Beefy-Tech Cool, very good to know. I know that it's probably nothing to do with thermal paste or the way the CPU is seated because temps are fine during idle. (ca. 32-40C depending on ambient temperature), and around 60-70 in gaming, which for this CPU on air cooling is pretty normal. Granted C23 is a synthetic benchmark it's unusual for anything else to push the cores that hard, I assume. Also the fact that the CPU doesn't really downclock that much during a full 10-minute pass must hopefully mean that it's alright, (knock on wood).
@@Beefy-Tech Oh, another thing: I'm just asking these questions because channels like HU would say something like: "I would leave undervolting to people who know what they're doing" etc. :)
@@iseeu-fp9po I mean people like to overcomplicate things. For this CPU undervolting has massive benefits, where it nearly behaves as an overclock (because it increases performance) and it decreases temperatures. There's no downside to doing it other than spending some time making sure it's stable, and you know, once you invest into a computer it's best to enjoy the maximum performance it can offer after all!
How do you know if the curve you applied is stable?? Sorry I'm really new and clueless to this.
With the pbo2 app after testing and everything is stable to keep the cpu at those settings do you just leave the app on and minimize or can you exit and close it ? Thanks for the tutorial!
If you do the apply at startup with task scheduler it's essentially minimized constantly, so yes u can just minimize it after you are done to make sure it doesn't unapply the stuff, although it shouldn't unapply it even if you close it entirely.
Hi need to put by default the curve optimizer in bios before using pbo2 tuner?
Hey Beefy. Just wondering if RAM oc is worth doing while running the 5800x3D or is it worth oc RAM with this chip? With my b550 I was only able to get minimal gains. Mind you I only increased frequency and voltage, no subtimings, Corsair Dominator 3200 cl16. Have you tried or had luck oc RAM together with 5800x3D? Cheers mate.
It's minimal gains. I went from a 3600mhz cl20 untuned kit to a 3800 cl14 fully tuned kit and gained like 10 fps in warzone 1 back when I did the upgrade. 5800x3d doesn't benefit as much from fancy ram, but it still helps it a bit.
@@Beefy-Tech cheers Beefy i thought was the case
Don't call him Beefy 😒.
Like he's one of your buddies from the street ...
He's Mr Beefy to you 😎
What ram faster ram helps with is the 1% low and .1% lows when gaming. The x3d cache helps this a lot but tighter tuned ram will increase the lows even more. You wont find much improvements in average fps but gameplay will be improved considerably as the lows are better. Best ram for the x3D will be 3600-3800 c14 with tight sub timings and 4000 c14-16 for 1:1 fclk if you are able to achieve it.
It does but the difference is only noticeable in the 1% lows went from 3600CL 16-18-18-36 to 3800 CL 16-16-16-32
my settings is -30 120 75 110 and i get 14905 cb23 score, and a tip this is the corect line whit limit on tasks. -30 -30 -30 -30 -30 -30 -30 -30 120 75 110 0( this setting is my personal tested)
whit tis line weill apply the full list on start not only the curve
Thank you! This worked perfectly on the 5800x3d. I gave 5800x3d to girlfriend though, so she is the one enjoying the no hassle undervolt xD.
the cpus are only unstable at idle. then yoou have to tweak based on what core is crashing in event viewer.
This stabilized my frames and temps! One doubt tho, I set it scheduled to -30 but when I open it sets automatically to 0, what could be the issue?
I have b550 auros pro v1 last bios and I use all cores negative -30 and cpu voltage offset to -60mV and will do even lower but I am on 102blck idk why my r7-5800x3d goes as highest 4.45Ghz on stock and now I made it go 4.54Ghz all cores stable on cinebench r23 multicore run and never drop below 4.54Ghz feels much faster than stock.
temp goes 55C on gaming and cinebench r23 multicore 10min run goes max 72C temp.
my old r5-5600x was like bit higer on wattage like 30W on max load but was amazing CPU for 4.9Ghz all cores for 2 years before I moved on.
I set all to -30 and changed nothing else and received the similar results, just with game memory boost in msi bios
When running tests without pbo I have higher average mhz but with pbo -20/-25 average is 3850 mhz, -15 average 4000mhz, average mhz is something to take in considerations or i should look for better performance/fps only in lower voltage and temperature?
It means past-15mv it's not helping frequency and performance anymore because it needs the extra voltage to boost higher, so stick with-15 for best performance.
I have set PPT=120 TDC=75 EDC=115 the curve at -30 cinebench is hitting 79.8c, and lowering EDC and/or SoC VDD actually increases temps by 4c.
I'm using NH-D14 so I don't know why I can't get any lower temps.
If temps get hard stuck, most likely your cpu thermal paste application wasn't done right, or cooler isn't making contact with cpu and paste properly. I recommend you take a look at that
@@Beefy-Tech repasted and the screws are bottoming out, either the bottom of the cooler and/or the IHS are similar in shape thus not contacting fully :/
@@GH1987 it's possible for it to be a contact issue, but hard to tell, I'd say worth considering a cooler change to an All in one liquid cooler to lower temps significantly.
Hello , i did everything like you, my pbo is not starting with windows...and all limits are reseted after i restart pc...can someone help me?
Once I download it from the google drive and save to desktop I don't have an option to extract. It's not even showing as a folder for me. any help is appreciated!
hey guys! I kind of need some help on figuring out why the AIO cooler (240 corsair) stops working randomly for a few secs after undervolting. No crashes, no BSODs, just the fans from the coolers randomly stops while set manually at extreme. Is this considered a system instability? Any ideas? Thanks!
I personally don't have much experience with that, but my assumption is that it uses more power then available when set to Max RPM's, or a connector loses connection for a short time. Very unlikely I'll actually be right, but I'm trying to throw some guesses out there lol.
Make sure everything is plugged in thoughouly, and update to latest bios drivers and chipset drivers if you haven't already.
@@Beefy-Tech thanks a lot for stepping in with some advice! everything was already updated to the latest version possible though :(. plus this never happened before undervolting :(
