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
@@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)

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.

@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?
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...
@@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.
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.
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 th-cam.com/video/0jkzGVoQs5w/w-d-xo.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..

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.
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 ?
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
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.
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🙌
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)
I got An Assassin III from Deepcool with -25 offset all cores being the most stable and 115W 75A 110A. In CPU demanding games the average Is 69/70 degrees going up to 74 for a split second. With more " normal " games it's about 65/66 degrees, sometimes going to 70 degrees. I do wonder if I Just didn't got the best pinned or if I'm missing something. Still, 11 to 12 degrees less than stock. Using the pc for 2-3 hours for gaming and I shouldn't have any issue, since it's 2 years that is running and temperatures are the same.
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
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!.
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
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.
@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
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.
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.
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%.
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!
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
@@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.
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
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.
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!

@@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
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.
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.
I just got myself a used 5800X3D....running -30 on all cores and PPT@100W...TDC@70A...EDC@100A. Seems to be rock solid, and temps are crazy low...70c running R23 multicore
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 :)
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
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
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.
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.
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...
I don't know if my 5800X3D is strange, but the max all core boost (4.02) I can get is if I set -50 curve and keep the TDC at max values. If i drop the TDC the frequency drops instantly. PPT and EDC I can keep maxed out because they never pass 70-80% of their max value. I don't know if my chip is strange or I'm doing something wrong.
Did not work for me at first. Apparently when you have "fast boot" enabled in BIOS the system doesn't shut down completely, so no cold boot and it won't trigger. What worked for me was setting the trigger to "At log on" instead of "At start up" ...maybe that helps someone who's struggling with this.
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 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.
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.
PBO2 Tuner has to be executing and in my task bar the whole time ? I noticed when I closed it, my temps jumped from 40ish to 60 while in idle. I'm using a cheap liquid cooling and for not having noise I set up in the bios to almost never use the fans, by default bios options my unit went 4550 mhz while benching with CB.
No if you don't give it enough power worst case scenerio you'll lose performance. The only things that can damage a 3D cache cpu are too much heat 95+ celsius, but it's limited way below that anyways, and to much voltage... but the cpu doesn't allow you to increase voltage, it only allows you to decrease voltage, which is perfectly fine
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.
@@Oujry I haven't yet, it worked for me one time when I booted my PC up and I could change all my values but otherwise... no luck. No clue why it doesn't work and why it only worked that one time, but thankfully you can just use the task scheduler to set them every time you boot up your PC. Would be nice to be able to experiment on the fly, but it's fine once you find good values.

Just tried PBO2 Tuning my 5800X3D (mobo - ASUS ROG Strix X570-F Gaming) and had the opposite effect. BIOS is alrady set to 142/95/140 and curve optimiser at -30. Running the OCCT CPU test the temps settle between 89/90.5deg and OCCT says the CPU is running at 4050ghz to 4100ghz all cores. OCCT says PPT/EDC/TDC usage is 118/81/108. Running Cinebench R23 then OCCT says CPU freq is locked in at 4300ghz. PPT/EDC/TDC settled around 112/77/121 I used PBO2 tuner to tweak PPT/EDC/TDC to 110/75/105 and ran Cinebench test again. This time CPU clock dropped to 3.9Ghz which is a 400Mhz loss. I know the 5800X3D is locked in terms of power and temp limits, so you can't really over clock it, but undervolting seems to slow down my CPU. Temps came down as well, but only by about 5deg. I have a Dark Rock Pro 4 cooler, which is supposed to be good enough. (I've tried fresh Thermal paste and made sure it is fitted correctly). Maybe I should grab an AIO water cooler? For me the results of undervolting were a small Temp reduction but also a 10% drop is CPU clock speed. I'm not sure what I need to do differently. My Mobo (ASUS ROG Strix X570-F Gaming) has a load of power settings I can mess with but I'm pretty sure I've got mine set to something reasonable.
Can Def handle it. I'm using a asrock b450 pro4 and it's just fine. This isn't a crazy high power chip like a 5950x or anything. Just remember you might need to update the bios to get it to run.
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.
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.
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 tried the above mention PBO tuning and also setting the voltage offset to -0.05000 but nothing changes..everything stays the same... i think my Galahad 360 cooler is dying or the cpu which is new is dead.. Lian Li are sending me a new cooler under warranty but that takes 3 weeks and i need a temporary cooler till then.
Im 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 ?
For 5800x3d -30 is the limit, but it's also very likely to be able to hit -30 which is great. Ryzen 7000x3d has up to -40, but can only sustain -30 on 4 cores generally, and -20 all core

@@Beefy-Tech what you mean by "sustain"? No crash/ blue screens? I`ve managed to go all cores -35 and test it in Cinebench23. No crash. My CPU is diffused in the USA. Don`t know if matters...but my 50 cents.
@@M4V3RiCkU235 I just meant the bins aren't as consistently good on 7950x3d as they were on 5800x3d. My 7950x3d sustains-30 on 7 of the 3d cores and -10 on best 3D core. But I've also seen people with keeping -20/-25 stable, so it'll vary between cpu's. My friend ran -35 on 3 cores and -30 on other 3 cores on his 7900x3d, so just like your cpu, it's possible to reach -35 or even -40 undervolts.
hi, im using pbo via the bios to customize my settings. I got -30 offset on all cores but I am unable to get my CPU core clocks to exceed 3600mhz speed. I see that yours reaches easily 4.4. Any idea what I am doing wrong? I also have installed the last chipset drivers, doesn't fix it.
You need to install the latest bios too, not only the chipset drivers. If you are already on latest bios, it's bugged out fully, so ull have to re-install the latest bios version from your motherboards website.
@@Beefy-Tech a small update: as suggested I have installed the latest bios, this led to the cpu core clocks unlocking successfully, thank you! ingame (wz2) they are now hovering between 4250 and 4400 mhz, cpu temps are reaching 63 degrees celsius under full load (-30 curve, PPT limit 100W, TDC limit 60A, EDC limit 80A). Do these numbers look ok to you? My beginner's eye is fine with what it is seeing. I don't think i'll be pushing the cpu any further for now. Thanks again!
I managed to set all cores to -30 on my own 5800x3d processor. However, I have to re-enter ppt tdc and edc every time I turn on the computer. I think I could not succeed in this part, please help.
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

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)

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?
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.

@@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.
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.
Thanks!

@@Beefy-Tech Help me PLEASE : PBO settings changed (getting defound values) when waking up from sleep/hibernation . Anyone how to fix?
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.

Thats because you had "clock-stretching". Few CPUs can go -30 all core without nuisance of "clock stretching" th-cam.com/video/jTkDqARDkGg/w-d-xo.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)

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.
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.

@@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.
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 :)

Great video my 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.

I just got myself a used 5800X3D....running -30 on all cores and PPT@100W...TDC@70A...EDC@100A. Seems to be rock solid, and temps are crazy low...70c running R23 multicore
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 :)
Yessirr -- 100 - 70 - 100 -30 all cores, 15 min test and its all stable.
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
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
Thanks, simple and fast, perfect.
Its not changing any settings for me? OCCT isnt showing any changes when i input numbers in PB02
one year with -30 all core and is awesome.
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.
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.
Thanks for this video, my 5800x3D run better now (-10°)
Awesome 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!
You can undervolt now in bios,just update them.
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?
I dont know if you can help but when I install the PBO2 tuner. My limits are all to 0 and I can't change them? Do you know why?
Did you figure this out?
@@Nuff.x I found a comment somewhere that it is bugged but they do actually change
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.
nice job man
any help? im getting a "smu status failed" also no values come up for the limits section other than maxboost
Тоже самое и у меня(
Thank you, good job
Hello question about the task scheduler, when I start my pc it says "ready" instead of "running" like the other tasks, is that okey?
I don't know if my 5800X3D is strange, but the max all core boost (4.02) I can get is if I set -50 curve and keep the TDC at max values. If i drop the TDC the frequency drops instantly. PPT and EDC I can keep maxed out because they never pass 70-80% of their max value. I don't know if my chip is strange or I'm doing something wrong.
Did not work for me at first. Apparently when you have "fast boot" enabled in BIOS the system doesn't shut down completely, so no cold boot and it won't trigger. What worked for me was setting the trigger to "At log on" instead of "At start up"
...maybe that helps someone who's struggling with this.
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
Thank you
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.
What is the reason using Task Schedular with a long procedure instead of doing the same thing in the bios within a minute?
thank u bro
1st I was told I had a 5800x3d. This shows it as a 5700x3d. And no matter what I change nothing happens. Do we have to have bios on auto?
dang man, thanks alot!
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.
PBO2 Tuner has to be executing and in my task bar the whole time ? I noticed when I closed it, my temps jumped from 40ish to 60 while in idle. I'm using a cheap liquid cooling and for not having noise I set up in the bios to almost never use the fans, by default bios options my unit went 4550 mhz while benching with CB.
It's normal for Temps to spike when opening and closing such apps, and in most tasks the frequency won't be different, just Temps better under losf
@@Beefy-Tech Well I followed all the steps and seems now benchmarking doesnt get me 90º but 79º. Thanks so much for this tutorial.
@@cybdan_ awesome to hear fam!
I decrease to PPT 90, TDC 75 and EDC 90, and my fps doesnt change, the temp reduce a lot. Is this can be damage to the processor?
No if you don't give it enough power worst case scenerio you'll lose performance. The only things that can damage a 3D cache cpu are too much heat 95+ celsius, but it's limited way below that anyways, and to much voltage... but the cpu doesn't allow you to increase voltage, it only allows you to decrease voltage, which is perfectly fine
@@Beefy-Tech Thank you
Great video!!!
My limits don't save once I boot my pc up and have to readd my limits everytime.
Does anyone know how to fix?
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.
I get SMU status failed when trying to change ANY of the limit values. It just says 0 next to PPT, TDC and EDC
exact same thing as me did you find any reasoning to it?
@@Oujry I haven't yet, it worked for me one time when I booted my PC up and I could change all my values but otherwise... no luck. No clue why it doesn't work and why it only worked that one time, but thankfully you can just use the task scheduler to set them every time you boot up your PC.
Would be nice to be able to experiment on the fly, but it's fine once you find good values.
@@vangledosh so for me I can change the PPT TDC AN EDC in pbo2 I can see that the changes happen in ryzen master but it still says 0 an smu failed but it does change I've no idea either man I've looked online everywhere an I cannot get a solution
I have the AsRock X370 Taichi with the 5800X3D, but I dont have the PBO stuff in Ryzen Master or in my BIOS. i will try this tool and report back
Just tried PBO2 Tuning my 5800X3D (mobo - ASUS ROG Strix X570-F Gaming) and had the opposite effect. BIOS is alrady set to 142/95/140 and curve optimiser at -30.
Running the OCCT CPU test the temps settle between 89/90.5deg and OCCT says the CPU is running at 4050ghz to 4100ghz all cores. OCCT says PPT/EDC/TDC usage is 118/81/108.
Running Cinebench R23 then OCCT says CPU freq is locked in at 4300ghz. PPT/EDC/TDC settled around 112/77/121
I used PBO2 tuner to tweak PPT/EDC/TDC to 110/75/105 and ran Cinebench test again. This time CPU clock dropped to 3.9Ghz which is a 400Mhz loss.
I know the 5800X3D is locked in terms of power and temp limits, so you can't really over clock it, but undervolting seems to slow down my CPU. Temps came down as well, but only by about 5deg.
I have a Dark Rock Pro 4 cooler, which is supposed to be good enough. (I've tried fresh Thermal paste and made sure it is fitted correctly). Maybe I should grab an AIO water cooler?
For me the results of undervolting were a small Temp reduction but also a 10% drop is CPU clock speed.
I'm not sure what I need to do differently. My Mobo (ASUS ROG Strix X570-F Gaming) has a load of power settings I can mess with but I'm pretty sure I've got mine set to something reasonable.
ty for the guide
do u think a aorus gygabyte b450-m motherboard could handle this cpu ? or would i present perfomance issues
Can Def handle it. I'm using a asrock b450 pro4 and it's just fine. This isn't a crazy high power chip like a 5950x or anything. Just remember you might need to update the bios to get it to run.
Yup no problem with handling cpu. The 5800x3d doesn't need crazy high wattage
hi,i have aourus b450 pro with r7 5800x3d only what must to do is update bios,air coler suck and changed for ek280 aio
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.
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.
Hi, I did the same you did but still hottttt😂. 83C in BF2042 and 80C in Warzone 2. I have a B550M elite aorus and ddr4 3600mhz + water cooler 360. what do you think i can do?
It could be the actual mounting of the cpu then... possibly not enough thermal paste and not enough contact?
My settings are -30 all cores , PPT 105 TDC 75 EDC 110 , i get max 79c on ryzen master using cinebench with the cpu being constant at 4.330-4,350 Mhz , is it good and stable ? can run cinebench without crash
My 5800X3D is idling at 60c and hits 90 as soon as anything gets turned on. I have tried the above mention PBO tuning and also setting the voltage offset to -0.05000 but nothing changes..everything stays the same... i think my Galahad 360 cooler is dying or the cpu which is new is dead.. Lian Li are sending me a new cooler under warranty but that takes 3 weeks and i need a temporary cooler till then.
It's most likely the cooler. A 5800x3d can't overvolt itself, and if it did your cpu would be dead already so it guaranteed the cooler.
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?
Im 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 ?
For 5800x3d -30 is the limit, but it's also very likely to be able to hit -30 which is great.
Ryzen 7000x3d has up to -40, but can only sustain -30 on 4 cores generally, and -20 all core
@@Beefy-Tech I see ya thought the same , didnt saw any yet with lower then -30 online, for 5800X3D .
Mersi pt. reply ! f bun video, ai explicat totul pas cu pas :)
Ai un sub nou :)
@@Beefy-Tech what you mean by "sustain"? No crash/ blue screens? I`ve managed to go all cores -35 and test it in Cinebench23. No crash. My CPU is diffused in the USA. Don`t know if matters...but my 50 cents.
@@M4V3RiCkU235 I just meant the bins aren't as consistently good on 7950x3d as they were on 5800x3d.
My 7950x3d sustains-30 on 7 of the 3d cores and -10 on best 3D core. But I've also seen people with keeping -20/-25 stable, so it'll vary between cpu's.
My friend ran -35 on 3 cores and -30 on other 3 cores on his 7900x3d, so just like your cpu, it's possible to reach -35 or even -40 undervolts.
hi, im using pbo via the bios to customize my settings. I got -30 offset on all cores but I am unable to get my CPU core clocks to exceed 3600mhz speed. I see that yours reaches easily 4.4. Any idea what I am doing wrong? I also have installed the last chipset drivers, doesn't fix it.
You need to install the latest bios too, not only the chipset drivers. If you are already on latest bios, it's bugged out fully, so ull have to re-install the latest bios version from your motherboards website.
@@Beefy-Tech thank you for getting back to me, i'll look into it. Thanks! :)
@@Beefy-Tech a small update: as suggested I have installed the latest bios, this led to the cpu core clocks unlocking successfully, thank you! ingame (wz2) they are now hovering between 4250 and 4400 mhz, cpu temps are reaching 63 degrees celsius under full load (-30 curve, PPT limit 100W, TDC limit 60A, EDC limit 80A). Do these numbers look ok to you? My beginner's eye is fine with what it is seeing. I don't think i'll be pushing the cpu any further for now. Thanks again!
I managed to set all cores to -30 on my own 5800x3d processor. However, I have to re-enter ppt tdc and edc every time I turn on the computer. I think I could not succeed in this part, please help.
If I’ve already set similar values within the bios, will PB02 tuner override them?
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
