@@ActuallyHardcoreOverclocking here's some screenshots. IDLE: ibb.co/kgMCfYF STRESS1: ibb.co/2vBDgpq STRESS2: ibb.co/YQqn0GH Note: PPT and TDC are set to 0 in the BIOS but ryzen master report different values. I dont know if setting them to 0 does actually mean the BIOS sets them to 142 and 95, but EDC is actually set to 1 as set in the BIOS.
i just tested EDC 999->25, PPT 999, TDC 999 on X570 Aorus Master F11 and 3950X, NH-D15, LLC High, Scalar 5X. I get CB20 from 9524->9872 Cpu-Z single 556.8->560.4 multi 10986->11467, P95 162-174W 80oC -> 200-220W 95oC. CnQ as C-states are enabled, i hit 4.7ghz in some cores. However it seems to keep the low load voltages that exceed the 25 EDC limit high (aka 1.45-1.5V) as well as the clocks of the cores which might not be safe for continuous use. Temps stay low because the cores don't do much work, but this is not the normal behavior. Only when a core sleeps it goes down to low voltage. But basically i think voltages just follow the boost multiplier set. So this way PBO basically breaks since it's over the limit and boosts the hell out of any load other than 0%/sleep.
2:00 you can look at "effective" clock speed instead of "Core clock", that metric pretty much counts all clocks that happened in that second. that option shows when your cores get clock stretching, e.g. when you set negative offset too low and run P95 small ffts you can see that your weakest rated core has lower Effective clock than any other core, while "Core clock" is the same.
A quick CPU benchmark would be much more useful than the clk speeds... For my 3600x PBO doesn't do anything for clockspeeds and actually reduces benchmarks a bit...
Bernardo de Pádua not talking about PBO here. I think you can pretty easily tell which settings perform better on average by comparing average effective clock speed while running heavy stress tests
EDIT: I also use Core "Offset Mode" with negative Offset of 0.1125 and this gaves me the maximum Multi Core CB20 result (near 7325 to 7400) . PBO disabled. I have a 3900X and 3600 MHz RAM on XMP on a MSI Unify board. EDC Limit goes to 100 %, PPT and EDC nearly 100 % (around 94 to 96 % I guess). This is no overclocking of course but it maxes my CPU performance. With PBO enabled, the EDC Limit stays under 50 %... but why? That makes no sense to me! It also gets far lower CB20 results (7000 to 7100). SoC kept on auto, because offset values or fixed 1.1 V will reduce my results.
gary With effective clock speed perhaps on a all core load... I don’t know how reliable this measurement is. But certainly not true for regular clock speeds. Eg.: you can add a very high negative Vcore offset and it will continue to boost at the same clock speeds with stability, but benchmark performance will degrade.
“Pbo does a good enough job” I agree with you that with manual overclocking we can't get much extra performace out of the chip. But that said,you can get a more efficient chip with it. 3700x PBO Cinebench R15 196W (82 C) 2165CB / 90W 205CB Manual OC 4,2ghz @ 1,28V (prime95 avx2 small FFT stable) Cinebench R15 157W (66 C) 2214CB / 82W 199CB *My wattage is total system power consumption.
Exactly. PBO did a shit job for me on 3600. It never boosted beyoned 4 GHz despite having the headroom to do so while using way too high voltages. I just OC'ed manually and lowered the voltage. Cinebench R20 - PBO - 3575 Cinebench R20 - Manual 4,2 GHz - 3797
of course manual OC will benefit multi-core application and will have lower power consumption than with PBO but with that you are losing single-core performance because core won't get higher than your set frequency and will have higher power consumption while idle
@@killerm12 Ohms law (P=U*I) states that if your pc doesnt have to work there is almost no extra power draw. But also in my case with my manual OC, I can observe in AMD Ryzen Master that my cpu still downclocks. Also if my math is right than: I gain 2,26% multithread performance and my system is 25% more power efficient. I lose 2,92% singlethread performace and is 9,75% more power efficient.
I really appreciate these videos by someone of repute. Because I've been having a nightmare time trying to performance tweak, and luckily enough I got a 3950x with an aorus xtreme motherboard. I was worried it might of just been the gigabyte board, but glad it's just the agesa. Aswell as the thermals with the 3950x, because I'm running on a 360 aio @ 100% fan/pump speed and it is TOASTY. Appreciated buildzoid
You should update HWINFO to see current PPT, TDC and EDC usage, it has rows for both current value and % of limit (either something is at 100% or pbo is just broken like you said)
5900x owner here with an Aorus Master. Can confirm this is still a thing. I found my magic numbers to be like 238. About 4.5-4.6 all core and 4.9 single core.
Please keep making not dumbed down content. I like struggling to figure what you’re saying. I feel like I learn way more that way. I’m pretty new to the OC scene and I think this is awesome.
NICE :) Is there a chance you'll do a tutorial on how to overclock 3950X on this motherboard? 1) version 1 only with PBO+AutoOC, including EDC error 2) version 2 with static CPU OClocks with offset voltage
Thanks Bz!! This is soo useful for me. I dont know or understand the Bios settings fully. I got 2 GB X570 boards and will want to do this similar test on each board with 3800X. This gives me better understanding of bios.
Hey BZ, this is exactly what I've been having with my 3900x and B450 Tomahawk since the latest agesa version. My solution is to just enable pbo and not manually enter any values , otherwise the cpu will lock itself at 530 Mhz.
Oh man, I love you!! xxx I tought PBO was broken on my MSI X370 Gaming Titanium with a 3700X I put the limits on 230 in the BIOS and now its willing to pull 130Watt, 3.975Ghz on prime95
@Erotikstudio Winkler GmbH Did you even watch the video? BTW the TDP would be 65W of a 3700X. It was stuck on 85Watt because PBO doesnt work properly when you give it unrealistic values like 999. The values provided in this video immediatly improved the performance of PBO
i got the 5800x3d on my Aorus x570s Master now for a couple days, i have put my all core neg -20, but if i put the cpu boost max to +200 then my cpu go's only till 3500 at full load, if i put it off, i get 4450.5 on most cores and on 2 cores its 4550.5, very strange ! so i cant put it on core neg-20 and then core max boost at +200 as some people can do...
Nice! I'll be using BIOS flashback to install BIOS version 1001 for the Asus X570 Crosshair VIII Hero right after leaving this comment. It appears to be the newest BIOS with the AGESA version 1003 ABBA.
I think there must be some type of power budgeting going-on? I did some incremental testing with my 3700X on a Crosshair VII Hero with 1.0.0.4 B and found the maximum power draw and boost clocks with the targets being set quite close to the actual limits. Testing with p95 and Cinebench R20 (for EDC draw) the maximum values that I could get the CPU to pull were 122.1W (PPT); 80.5A (TDC); and 109.7A (EDC). The best performance, for me, was found with the PBO limits set so that these max draws were about 95% of the limit - 129W (PPT); 85A (TDC); 116A (EDC). Obviously the specific numbers would be much different in the case of a 3950X, but the PBO boost behaviour may run along the same lines?
3700X settings do not apply to 3950X. The 3700X is much lower binned, has lower tolerances as a result and by definition can't boost as high and has fewer cores/CCX etc. You would make more sense of you posted about an I7 7700K!
@@downwiththatsortofthing624 thanks for your helpful input; I am quite aware of the differences between a 3700X and 3950X. To your "point", binning and core count have exactly nothing to do with what I was trying to suggest about the basic behaviour of PBO. Clearly the specific values that I stated are not applicable in this case, nor did I imply that they were! You would make more sense if you kept your salty opinions to yourself if you don't have anything useful to contribute.
I get 4224 Mhz (4.2 Ghz) all core on my 3950X at only 110 Watts just by setting XFR and PBO on (all power savings set to on/auto). I'm running latest BIOS (6.20 - ABBA 1.0.0.4 Patch B which was originally a BETA BIOS, but has recently been set as a 'main' BIOS by Asrock) on an Asrock X370 Fatal1ty Gaming Pro with 3200 RAM @ CL14... Its been running 24/7 for over a month running handbrake rendering H.265 and never falls below 4.2 Ghz all core, even when I run simultaneous/multiple instances of different video creation software packages (with occasional 4.34 Ghz boost)... Go figure!
4.2 overclock at 1.2875V in RM gives me around 200 higher score in CB20 than PBO 320 and auto overclock +200Hz. With lower temperature of 70C vs 80C and lower power 145W vs 170W. Not interested in the slightly higher scores from manual OC but the lower temps and power are attractive. Gigabyte Elite BIOS F11. Manual OC seems to be the way to go.
I have 6 Noctua fans, 3 of which are industrial ( 2x 2000 rpm, 1x 3000 rpm) in a Cooler Master NR600 case and a Asus ROG B450-f motherboard and a Ryzen 5 2600x with stock cooling. Soon to be Noctua NH12 SE4 cooler. What should I change in my bios for overclocking?
I just got my 3900x installed, and tried PBO and auto-overclock. It pumped by voltage up to 1.47V and turboed up to 4.512 on some cores, with a package power usage at ~180W. I turned off PBO and auto-overclock, and the voltage dropped down to 1.32V, and my chip turboed up to the exact same clock rates, at ~120W package power. So, I keep PBO off now. Talk about annoying.
Not relevant to this video/content! Your CPU is binned as a 3900X because it has been tested and found to need more voltage/create more heat than the chips in the 3950X, and it was sold that way open and honest by AMD, thats why the 3950X draws less/equal power than the 3900X, despite having more cores!
@@dangingerich2559 Except your point was stupid as it clearly works, as I get 4.3 Ghz wih PBO on all core boost on my 3950X at just 110 Watts (VDD 1.09 volts) and 43 Degrees C.... Which will be lower than your 3900X despite having significantly more cores as its a totally separate SKU! You're an idiot!
doesn't seem to matter what settings I use for PBO, my r5 3600 does 3.9ghz @ 60C in cinebench, using about 80 watts.. only thing that gets any actual results is a manual overclock (Asus x570 TUF, 1405 bios)
i have a 3800x on this same mobo... AC of 4.425@ 1.306v works 9 of 10 days.. Not sure how to interpret what im seeing but i can run Cin R20 on a 10 minutes run most days with no issues... and then there is that one day that is just will not stay stable.. Runs fine in a 3 hour loop of aida 64 as well. guess i need to get prime 95 for most testing. Cant figure out if after a few weeks my cpu is degrading @ 1.306v or if im just testing too much LOL.
@@Rigg5 -.1 degrades performance for me but does stay really cool, under 75c. -.05 has better performance and still stays cool under 80c. -.025 has the best performance and still only hits about 82c on 240 water. That is all I got to test before I had to take off this morning. -.1 had a max boost of 4.5 while -.05 & -.025 both had max boosts of 4.6. Oddly enough the closer I get to auto voltage the higher sustained clock I keep while running r20 which leads to higher scores. @ -.1 r20 scored about 4400 .-05 was 4900 and -.025 was 5050. At some point all cores boosted at least once to 4.5 and more than half hit 4.6 with -.025. I'll continue to dial it in little by little to get best performance while keeping temps under 85c which is my goal.
I’m running a 3950x on the Crosshair VIII Hero and if I enable PBO and XMP, the machine instantly black screens when I start a small FFT run. Any ideas why? If I drop the p95 thread count to 24 it doesn’t crash, so my guess is power? Running a 1000W Seasonic Prime TX though.
@@ActuallyHardcoreOverclocking what is your thoughts on the max V for Ryzen 3000 without degrading your CPU? I have seen a lot of answers out there, but i respect your opinion. I have managed to get an AC OC of 4.425 on my 3800x that is stable 9 of 10 days @ 1.306v. Will this kill my CPU?
what's it do if you do the undervolt method you showed us before on MSI boards for zen+ ? Just curious because i get the best performance from -0.0812 offset , PBO enabled, power scalar disabled, on my 2700x.
on 3rd gen it has a lot less effect than on 2nd gen. My 3700X spits out basically the same scores form +50mv all the way down to -100mv bellow that it crashes.
would you write your secondary timings for B-die that always works to a google drive text doc please? I tried writing them down but you say them quickly and i get lost haha. Thanks for all of your videos, I have learned so much from you, really appreciate them.
Timings depend on the exact memory module you have, not all B-dies can reach the same timings, so there isnt really a "always works for every module" setting out there. (outside of stock/jedec timings) If you want safe settings then the XMP profiles on your modules should work.
@@DeadNoob451 I'm not talking about primary timings. You must not watch his mem over clocking videos where he says the secondary timings that almost always work with b-die
can you redo this for bios F20 ? it was a big change for PBO in my aorus elite wifi for the 2700x ... yes ... ryzen master was able to apply pbo for my chip for that
Besides binning, are these the only settings that differentiate the default behavior of the 3700x and 3800x? Meaning if you are to tweak the settings then the only reason to go 3800x is due to a better chance of a slightly better chip?
@@vladvah77 and actually that makes me think that there's no difference between 3700 and 3800 except the 3800 can clock higher because of better silicon. it does boost to 4550 regularly on multiple cores.
didnt you showed on one of the ram oc videos that anything after x4 or x5 have no returns or performance now i want to try this on my 2600x lol Buildzoid's outros are the best !!!!!
Could you get around the voltage issue with a negative offset on auto voltage or perhaps even better with intentionally allowing vdroop so that at load even though the CPU asks for 1.2, it gets 1.15 so it generates less heat? Although I guess then it'd just go 'hey there's room here, gimme 1.25v, oh wait now I'm hot, back to 40.5 and 1.15'.
@@cracklingice Thats odd, even my b450 tomahawk has a vrm temp sensor. I hate it when mainboard manufacturers cheap out on stuff like that. Should cost almost nothing to implement but nope, gotta save those 0.01$.
@DeadNoob The worst part is that I'm pretty sure when I googled the Intersil ISL6367/ISL6379 that at least one of them said they had temp sensors and apparently Asrock just didn't bother to expose them.
Just replaced my 9900k with a 3950x. I get 4000 to 4050 Mhz when I max out PBO settings (1000A, 1000degC) on the Aorus master. Haven’t run P95 at 128k, but Cinebech(es) hit 150ish watts. My chip boots at 4.2 Ghz at bios Vcore at 1.325v. Droops down to 1.2ish volts, and Cinebench erred. Haven’t had any more time to OC it. Extremely impressively chip, especially for the money. I will probably run this at stock auto setting because it runs cool, assuming it passes all my stability tests.
Same as "knock" in cars. If the ecu detects knock then it will pull back the ignition timing which if you're trying to make power...loses power, So rather than running the most extreme timing and then experienceing knock you can get more by just being conservative and not knocking in the first place. Haven't started using my 2700x system yet (b450 gaming plus AC) but on early testing I can't even get my corsair LPX 2400mhz cl16 to run at XMP, default 2133 cl15 and thats it. yay.
did you do an all core OC? or is this a possible boost limit between 4.425 and 4.5? If so i didnt know this was possible... and wold be interested in learning how to do that.
win tejr all core on 4.425 but i could only get one ccx to hit 4.5ghz, I’m not the greatest at overclocking wish i could share some knowledge but all i did was change llc, the multiplier and voltage. As far as my 4.425 oc i just used the bios but as far a my 4.5ghz i did ccx overclocking with ryzen master. Honestly there’s not that much difference in performance from 4.3-4.5 in daily use and gaming. The biggest difference is using faster ram with good timings. I use 3600mhz cl16 tuned to cl14z. But if you have a 3900x or 3950x their i little better binned than the rest of ryzen 3000 cpu’s 3950 more so. My 3600 will only do 4.2ghz same as my 2700x. I keep my 3900x at 4.4ghz now at 1.33v
@@ChadKenova ok I was not able to get one of my cc stable @ 4.5 even using higher voltage up to 1.4 just to see if it would. Not sure why but my 4.425oc is stable 9 of 10 days in r20.. that last day it cant get past the first 15 seconds before it crashes. I adjusted llc and seems to be more stable but I will continue to test and see how it goes.
0:46 I'm sure you are well aware that a fair proportion of R9 3900x owners are gamers who bought it just because it's the "best" AMD CPU (not counting the 3950x for availability and price reasons). Because when you are a tRuE GamEr you just need the best.
tried this with my 3900x on a gaming M7 X470 board. auto PBO gives the highest frequency when doing prime 95 but that doesn't translate into performance. running R15 auto gives the worst frequency and score compared to max PBO. 4000mhz Vs 4200 mhz on max pbo for R15. Running AGESA 1.0.0.3ab
hello , in my test´s i found out that if you use ram speed above 2666 the aditional SOC voltage makes the temp´s go way higher (2700 non X) - my oc 4.0 ghz@1.25v@117W/ram 2666mhz@1.25v SOC@0.975v - cpu temp@ full load 62c(winter) - my guess here is that the infinity fabric chip or chip´s generate a lot of aditional heat above 1333mhz , can you plz make the same test´s but keep the ram @ 2400/2666 you will find you get a lot lower temp´s.
so what are them other 2 mobos you tested this on? I'm using an x570 taichi AGESA 1.0.0.4.B , 3900x pbo on, maxed limits , highest boost is 4650mhz and lowest is 4325mhz, stays all core 4200 majority of the time
I don't think this is it.... ...but the inital tests are consistent if we assume the limit you input is truncated to eight bits somewhere along the line; 555->43, 333->77, 230->230, 999->231.... so under this hypothesis 555 should result in the same limit as 299. Just a random thought I had watching.
I hate all the auto OC features and boost algorithms on AMD and Intel. I went from Sandy Bridge E to 9th gen coffee lake a year ago and that auto config crap is driving me crazy (both are Asus ROG boards) . Even after disabling and setting manual values on all the auto ones (voltages, memory timings up to tertiary timings) and the system is perfectly stable after torturing it for hours and using it for days. Somehow whenever there is a major OS or hardware driver update forcing (multiball) reboots settings get ignored or changed resulting in a post fail and then the board retrains the memory (this and other settings were disabled in bios even the switch on the board itself) just F-ing things up even more. If i'm lucky it stabilizes after several reboots with insane auto voltages set on everything skipping safe boot values. If you would run those settings for a while you'd fry it. I just have to get in bios reload my saved profile to solve it like wtf ??? While with every bios update they claim to stabilise something and better memory support (my kit was officially supported from day one) but in my opinion the auto thing get worse. If it didn't had dual bios i would have bin screwed by the latest one.
@Erotikstudio Winkler GmbH You get 4 Cores more on the 3900X"... Yes, but for the same power envelope or even higher than the 3950X! Not sure the poster needs the power of the 3900X or the 3950X for that matter, but on a system on for the whole day every day, if the CPU is maxed out, you will actually save money in the longer term with the 3950X due to its greater power efficiency.... Not your fault, the poster asked what's better, but failed to ask better than what?
Lol. Just type in some numbers, try it out, ramble on, confirm it doesn't work, type in some other random numbers and try again, ramble on. Repeat until results lol.
1.0.0.4 is just bad, it's instantly 10C more idle and if you think 33C idle was bad, well it's upto 53C idle with 1004. Sadly now I'm stuck with ABBA until AMD makes 1.0.0.5 that hopefully works right and can finally get possible bios updates too. For me a max voltage limit would be far more useful than PBO, I'd set that to 1.3V and be a happy camper. I don't want 1.45V for nothing but heat. 3.6ghz is plenty for watching this video or making this comment :) (3600X base clock). AMD logic somehow is MAX voltage MAX boost all the time for everything! need more POWER! "I see 3% load in one thread, engage 1.45V and 4.4ghz!" "background processes need love too" no they don't, they are on background for a reason. But load is great, if you can do 12x 4.125mhz with 1.312v (Cinebench R15), surely CPU should know how to do 1x 4.125mhz with 1.312v, but Ryzen can't.. It should even do 1.312v 4,4ghz as it's only 3% load, opposed 100%. Now as the CPU is somehow that stupid, having a voltage limit "this is what you get, deal with it" would make the CPU do that 1.3V 4ghz boost, if it can't do full 4.4ghz then do 4.1ghz for internet browsing. Anyways, thanks for the video, nice to see that PBO stuff as I can't use them, silly AMD locking them behind warranty loss.
20:03 - Ive noticed with Intel and nvidia their hardware seems to know the limits out of the box where as with AMD it seems to figure it out in realtime with no memory of what CPU has been capable of, it would be interesting if AMD made their hardware recognise what it can do over time so It'll just step down voltage over a while.
Start with 230 / 230 / EDC 1, +200MHz, Scalar 1x-2x. Disable Cstates! I have also 130-140% on the current capability, llc auto. I tried alternatives with Cstates enabled and all EDC values between 1 and 25 with my 3950X, but EDC 1 and Cstates disabled works best. Scalar 1-2x should be a start, to not ramp up temps / volts too high. You could later play around with medium-high llc (some droop) + positive vcore offset, OR with llc high + negative vcore offset. enjoy!
Are you superstitious? You backed down from using 666 PBO limits :P Also ASUS and others were artificially increasing boost higher than stock on 1.0.0.3ABBA so they weren't running at AMD spec. So that could explain the difference here. This info came from Mukmark the HWinfo creator. Also, there has been a number of ASUS specific cases with the C6H/C7H such as PBO limits being frozen on Ryzen Master and HWinfo on anything older than 1.0.0.4. So AGESA isn't a cop-out for shoddy board partners as this was specific to the C6H/C7H only. I don't think you have done enough research on this subject prior to this video. PS I have been banned from that weird AMD meme subreddit, that sub is more toxic than Intel & Nvidia sewer sytem combined
Try PTT200/TDC130/EDC10 it weird but works just fine on my X570 Aorus I Wifi ITX... CB R20 should be 5000+ (my record with watercooling and tuned Ram is 5303)
Check for 1usmus's articles about PBO and OCing Ryzen overall. You get more clock, when the temps are low. I get highest performance on Ryzen r5 3600 on these settings. Offset -0.1V AutoOC 500Mhz.
What annoys me on my 3950X is the differences between cores 0-7 and 8 - 15 in regards to the boosts. It's 2-300 Mhz difference. Also the only way I can get 4.7 Ghz on a single core and yes it's just one single core out of 16 fixed, is to enable PBO. I'm running an EK Velocity block with 280 + 360 rads and a D5. Yep PBO is weird for sure.
@@downwiththatsortofthing624 I'm just running the XMP profile 16-19-19-19 at 3800. I have Hynix DJR and it's kind of obscure to get good info on timings that work without spending hours messing around. I'm running a GB Aorus X570 Master.
Have you tried both overclocking menus? I thought AMD said they created an AMD sanctioned overclocking menu, but then also let board partners implement their own overclocking menu. This seems like the type of thing that could be broken in one but not the other.
I wondered why my MSI X570 Unify had two different overclock menus with very little discernible correlation between the two. I wonder which is AMD’s and which is the board’s?
Yeh, PBO really doesn't seem that great to me. On my 3600 I ended up turning it off and overclocking it instead because why the fuck would my CPU boost some core with >=1.4V in idle when legit nothing's going on, shortly spiking my CPU temps to the point where fans ramp up a bit. Have a 1.3V @4200MHz profile and one with 1.1625V @ 4000MHz all-core. Great performance and no pointless boosting and temp spikes.
Same here with a 3700X, I run 1.25V @4100MHz and it's nice and cool at idle, although I still did have to mess with the fan profile since I tend to run high ambient temps in the room and it was still ramping up and down every few seconds (stock cooler). Now all is quiet until the chip actually has some work to do.
I've been using Ryzen Master on my none X 3600 on an Asus b450-I motherboard to run at ccx0-4375mhz ccx1-4325mhz 1.38125v. I'm scoring some really good numbers with a 14cas 3600mhz Neo kit
www.techpowerup.com/forums/threads/help-oc-ryzen-5-3600.262985/ "None of these 3000 chips are actually designed for all-core boost on 6 or 8 cores past 41.5x"
Like I said my 3600 on a stock cooler can do 4.3 with 1.33 vcore and pushed further with a better cooler and per ccx overclocking can do ccx0-4375mhz and ccx1-4325mhz chips will degrade inside 3 months pushing 1.4v or more i know that for a fact but at 1.38125vcore I've not seen an issue I'm still scoring nice and high on everything months later. The problem is Current that is what kills a cpu High voltage is fine if you can cool it and not keep the cpu pegged at 100% at the same time the more cpu you use the less voltage you should throw at the cpu for daily higher clocks. 100% usage plus high voltage = a lot of current. Silicon lottery plays a large roll in all of this though. Some will take more abuse than others and some will clock higher it's luck of the draw. My physics score in Fire strike is 67.24 fps. If you are that worried at all about overclocking I'd advise you to just let it auto boost. I've played with everything but a 3950x and they all will hit atleast 4.3 on 1.38v and its easily cooled at that voltage.
@@DeadNoob451 like I'm worried if a $160 cpu suddenly eats it >.> all these people that have no idea what they are talking about is more like it even Silicon Lottery Themselves sell pre binned chips at 1.325v and everyone here thinks 1.3v is too much LMFAO.

To all the people suggesting I use really low values for the EDC limit that doesn't work with my CPU. It just ends up running at 800MHz
EDC = 1 works for me. BUT... and thats a BIG "BUT".. im on a Asus x370 board (C6H).
EDIT: you have also to set PPT and TDC to 0

@@ActuallyHardcoreOverclocking Now That I'd like to see :D
@@ActuallyHardcoreOverclocking Did you try at all with less PBO Scalar? This at X10 is super agressive with voltage sustainabilty.
@@ActuallyHardcoreOverclocking here's some screenshots.
IDLE: ibb.co/kgMCfYF
STRESS1: ibb.co/2vBDgpq
STRESS2: ibb.co/YQqn0GH
Note: PPT and TDC are set to 0 in the BIOS but ryzen master report different values. I dont know if setting them to 0 does actually mean the BIOS sets them to 142 and 95, but EDC is actually set to 1 as set in the BIOS.
Not gonna lie, every time i needed to reference my 3600's clock speed i picked up the box it came in
i just tested EDC 999->25, PPT 999, TDC 999 on X570 Aorus Master F11 and 3950X, NH-D15, LLC High, Scalar 5X. I get CB20 from 9524->9872 Cpu-Z single 556.8->560.4 multi 10986->11467, P95 162-174W 80oC -> 200-220W 95oC.
CnQ as C-states are enabled, i hit 4.7ghz in some cores.
However it seems to keep the low load voltages that exceed the 25 EDC limit high (aka 1.45-1.5V) as well as the clocks of the cores which might not be safe for continuous use. Temps stay low because the cores don't do much work, but this is not the normal behavior. Only when a core sleeps it goes down to low voltage. But basically i think voltages just follow the boost multiplier set. So this way PBO basically breaks since it's over the limit and boosts the hell out of any load other than 0%/sleep.
2:00 you can look at "effective" clock speed instead of "Core clock", that metric pretty much counts all clocks that happened in that second.
that option shows when your cores get clock stretching, e.g. when you set negative offset too low and run P95 small ffts you can see that your weakest rated core has lower Effective clock than any other core, while "Core clock" is the same.
A quick CPU benchmark would be much more useful than the clk speeds... For my 3600x PBO doesn't do anything for clockspeeds and actually reduces benchmarks a bit...
Bernardo de Pádua not talking about PBO here. I think you can pretty easily tell which settings perform better on average by comparing average effective clock speed while running heavy stress tests
EDIT: I also use Core "Offset Mode" with negative Offset of 0.1125 and this gaves me the maximum Multi Core CB20 result (near 7325 to 7400) . PBO disabled. I have a 3900X and 3600 MHz RAM on XMP on a MSI Unify board.
EDC Limit goes to 100 %, PPT and EDC nearly 100 % (around 94 to 96 % I guess). This is no overclocking of course but it maxes my CPU performance. With PBO enabled, the EDC Limit stays under 50 %... but why? That makes no sense to me! It also gets far lower CB20 results (7000 to 7100).
SoC kept on auto, because offset values or fixed 1.1 V will reduce my results.
gary With effective clock speed perhaps on a all core load... I don’t know how reliable this measurement is. But certainly not true for regular clock speeds. Eg.: you can add a very high negative Vcore offset and it will continue to boost at the same clock speeds with stability, but benchmark performance will degrade.
A quick CPU benchmark will always be more reliable.
“Pbo does a good enough job” I agree with you that with manual overclocking we can't get much extra performace out of the chip. But that said,you can get a more efficient chip with it.

This did the trick for me 150 more points in cinebench with 4.2 oc
Exactly. PBO did a shit job for me on 3600. It never boosted beyoned 4 GHz despite having the headroom to do so while using way too high voltages. I just OC'ed manually and lowered the voltage.
Cinebench R20 - PBO - 3575
Cinebench R20 - Manual 4,2 GHz - 3797
of course manual OC will benefit multi-core application and will have lower power consumption than with PBO
but with that you are losing single-core performance because core won't get higher than your set frequency and will have higher power consumption while idle
@@killerm12 Ohms law (P=U*I) states that if your pc doesnt have to work there is almost no extra power draw.
But also in my case with my manual OC, I can observe in AMD Ryzen Master that my cpu still downclocks.
Also if my math is right than:
I gain 2,26% multithread performance and my system is 25% more power efficient.
I lose 2,92% singlethread performace and is 9,75% more power efficient.
I really appreciate these videos by someone of repute. Because I've been having a nightmare time trying to performance tweak, and luckily enough I got a 3950x with an aorus xtreme motherboard. I was worried it might of just been the gigabyte board, but glad it's just the agesa. Aswell as the thermals with the 3950x, because I'm running on a 360 aio @ 100% fan/pump speed and it is TOASTY. Appreciated buildzoid
You should update HWINFO to see current PPT, TDC and EDC usage, it has rows for both current value and % of limit (either something is at 100% or pbo is just broken like you said)
Will you cover PBO2 curve optimizer?
5900x owner here with an Aorus Master. Can confirm this is still a thing. I found my magic numbers to be like 238. About 4.5-4.6 all core and 4.9 single core.
What motherboard and BIOS version? Is your chip safe using EDC bug?
@@vladvah77 x570 Aorus Master. Latest bios I think 33j. My chip runs pretty hot, up to 90c but AMDs spec considers that safe.
Please keep making not dumbed down content. I like struggling to figure what you’re saying. I feel like I learn way more that way. I’m pretty new to the OC scene and I think this is awesome.
NICE :)
Is there a chance you'll do a tutorial on how to overclock 3950X on this motherboard?
1) version 1 only with PBO+AutoOC, including EDC error
2) version 2 with static CPU OClocks with offset voltage
Thanks Bz!! This is soo useful for me. I dont know or understand the Bios settings fully. I got 2 GB X570 boards and will want to do this similar test on each board with 3800X. This gives me better understanding of bios.
there is a trick. if you want to maximize clockspeeds you have to set PPT = 0, TDC = 0, EDC = 1
0 = auto on my board :X

Hey BZ, this is exactly what I've been having with my 3900x and B450 Tomahawk since the latest agesa version. My solution is to just enable pbo and not manually enter any values , otherwise the cpu will lock itself at 530 Mhz.
530 Mhz=Eww! Like it's a craptop!
Thanks, this helped me on my 3600 nonx. Setting to 230 moved clocks up a little.
will be any video about pbo 2 and curve optimizer ?
Has anyone gotten pbo to boost over the max rated speed? Or is the max speed still the global limit for each chip?
I don't think anyone has gotten it anywhere near its max speed of 4.7 Ghz, let alone OC that...
One reason your PBO is aggressively pursuing voltage at full load is your scalar is set to 10x. A more reasonable value is 1x or 2x.
Oh man, I love you!! xxx
I tought PBO was broken on my MSI X370 Gaming Titanium with a 3700X
I put the limits on 230 in the BIOS and now its willing to pull 130Watt, 3.975Ghz on prime95
It was stuck on 80-85Watt, whatever the workload before
@Erotikstudio Winkler GmbH Did you even watch the video?
BTW the TDP would be 65W of a 3700X.
It was stuck on 85Watt because PBO doesnt work properly when you give it unrealistic values like 999.
The values provided in this video immediatly improved the performance of PBO
@@hannahkiekens5097 the normal realworld powerconsumption of a 3700x is around 88watts the TDP isnt the same as the powerconsumption.
i got the 5800x3d on my Aorus x570s Master now for a couple days, i have put my all core neg -20, but if i put the cpu boost max to +200 then my cpu go's only till 3500 at full load, if i put it off, i get 4450.5 on most cores and on 2 cores its 4550.5, very strange ! so i cant put it on core neg-20 and then core max boost at +200 as some people can do...
This bug is STILL present in 1.2.0.3B. This video reassured me that I wasn’t actually going crazy.
So how does one find the FiT limits if you can't use the Max PBO on older AGESAs any more?
Nice! I'll be using BIOS flashback to install BIOS version 1001 for the Asus X570 Crosshair VIII Hero right after leaving this comment. It appears to be the newest BIOS with the AGESA version 1003 ABBA.
I think there must be some type of power budgeting going-on? I did some incremental testing with my 3700X on a Crosshair VII Hero with 1.0.0.4 B and found the maximum power draw and boost clocks with the targets being set quite close to the actual limits. Testing with p95 and Cinebench R20 (for EDC draw) the maximum values that I could get the CPU to pull were 122.1W (PPT); 80.5A (TDC); and 109.7A (EDC). The best performance, for me, was found with the PBO limits set so that these max draws were about 95% of the limit - 129W (PPT); 85A (TDC); 116A (EDC). Obviously the specific numbers would be much different in the case of a 3950X, but the PBO boost behaviour may run along the same lines?
3700X settings do not apply to 3950X. The 3700X is much lower binned, has lower tolerances as a result and by definition can't boost as high and has fewer cores/CCX etc. You would make more sense of you posted about an I7 7700K!
@@downwiththatsortofthing624 thanks for your helpful input; I am quite aware of the differences between a 3700X and 3950X. To your "point", binning and core count have exactly nothing to do with what I was trying to suggest about the basic behaviour of PBO. Clearly the specific values that I stated are not applicable in this case, nor did I imply that they were! You would make more sense if you kept your salty opinions to yourself if you don't have anything useful to contribute.
I get 4224 Mhz (4.2 Ghz) all core on my 3950X at only 110 Watts just by setting XFR and PBO on (all power savings set to on/auto). I'm running latest BIOS (6.20 - ABBA 1.0.0.4 Patch B which was originally a BETA BIOS, but has recently been set as a 'main' BIOS by Asrock) on an Asrock X370 Fatal1ty Gaming Pro with 3200 RAM @ CL14... Its been running 24/7 for over a month running handbrake rendering H.265 and never falls below 4.2 Ghz all core, even when I run simultaneous/multiple instances of different video creation software packages (with occasional 4.34 Ghz boost)... Go figure!
I don't know half of what's going on here but I will absorb this information and eventually I'll find out what it all means.
slightly off topic thing - the video doesn't have the option to display in 720p but it can be displayed in 1080p or 480p lol
4.2 overclock at 1.2875V in RM gives me around 200 higher score in CB20 than PBO 320 and auto overclock +200Hz. With lower temperature of 70C vs 80C and lower power 145W vs 170W. Not interested in the slightly higher scores from manual OC but the lower temps and power are attractive. Gigabyte Elite BIOS F11.
Manual OC seems to be the way to go.
Cheers for this. Might explain why pbo does literally nothing on my system.

I just got my 3900x installed, and tried PBO and auto-overclock. It pumped by voltage up to 1.47V and turboed up to 4.512 on some cores, with a package power usage at ~180W. I turned off PBO and auto-overclock, and the voltage dropped down to 1.32V, and my chip turboed up to the exact same clock rates, at ~120W package power. So, I keep PBO off now. Talk about annoying.
Not relevant to this video/content! Your CPU is binned as a 3900X because it has been tested and found to need more voltage/create more heat than the chips in the 3950X, and it was sold that way open and honest by AMD, thats why the 3950X draws less/equal power than the 3900X, despite having more cores!
@@downwiththatsortofthing624 My point was more than PBO does pretty much nothing and shouldn't be relied on for any significant boost.

would you write your secondary timings for B-die that always works to a google drive text doc please? I tried writing them down but you say them quickly and i get lost haha. Thanks for all of your videos, I have learned so much from you, really appreciate them.
Timings depend on the exact memory module you have, not all B-dies can reach the same timings, so there isnt really a "always works for every module" setting out there. (outside of stock/jedec timings)

How do you make sense of the pbo values you entered in the bios?
Besides binning, are these the only settings that differentiate the default behavior of the 3700x and 3800x? Meaning if you are to tweak the settings then the only reason to go 3800x is due to a better chance of a slightly better chip?

10x is just for maxing out the voltage limits I don't expect it to yield the best performance but I do expect it to pull the most power.
Could you get around the voltage issue with a negative offset on auto voltage or perhaps even better with intentionally allowing vdroop so that at load even though the CPU asks for 1.2, it gets 1.15 so it generates less heat? Although I guess then it'd just go 'hey there's room here, gimme 1.25v, oh wait now I'm hot, back to 40.5 and 1.15'.

Just replaced my 9900k with a 3950x. I get 4000 to 4050 Mhz when I max out PBO settings (1000A, 1000degC) on the Aorus master. Haven’t run P95 at 128k, but Cinebech(es) hit 150ish watts. My chip boots at 4.2 Ghz at bios Vcore at 1.325v. Droops down to 1.2ish volts, and Cinebench erred. Haven’t had any more time to OC it. Extremely impressively chip, especially for the money. I will probably run this at stock auto setting because it runs cool, assuming it passes all my stability tests.
Same as "knock" in cars.
If the ecu detects knock then it will pull back the ignition timing which if you're trying to make power...loses power, So rather than running the most extreme timing and then experienceing knock you can get more by just being conservative and not knocking in the first place.
Haven't started using my 2700x system yet (b450 gaming plus AC) but on early testing I can't even get my corsair LPX 2400mhz cl16 to run at XMP, default 2133 cl15 and thats it. yay.
Is the average Aorus X570 bios well sorted enough to run a 5950X without issues?
Most of the settings dont seem to do shit on my crosshair viii, and the all core boost is not great so I manually oc to 4.425-4.5ghz on my 3900x.

win tejr all core on 4.425 but i could only get one ccx to hit 4.5ghz, I’m not the greatest at overclocking wish i could share some knowledge but all i did was change llc, the multiplier and voltage. As far as my 4.425 oc i just used the bios but as far a my 4.5ghz i did ccx overclocking with ryzen master. Honestly there’s not that much difference in performance from 4.3-4.5 in daily use and gaming. The biggest difference is using faster ram with good timings. I use 3600mhz cl16 tuned to cl14z. But if you have a 3900x or 3950x their i little better binned than the rest of ryzen 3000 cpu’s 3950 more so. My 3600 will only do 4.2ghz same as my 2700x. I keep my 3900x at 4.4ghz now at 1.33v

0:46 I'm sure you are well aware that a fair proportion of R9 3900x owners are gamers who bought it just because it's the "best" AMD CPU (not counting the 3950x for availability and price reasons). Because when you are a tRuE GamEr you just need the best.
tried this with my 3900x on a gaming M7 X470 board. auto PBO gives the highest frequency when doing prime 95 but that doesn't translate into performance. running R15 auto gives the worst frequency and score compared to max PBO. 4000mhz Vs 4200 mhz on max pbo for R15. Running AGESA 1.0.0.3ab

I don't think this is it....
...but the inital tests are consistent if we assume the limit you input is truncated to eight bits somewhere along the line; 555->43, 333->77, 230->230, 999->231.... so under this hypothesis 555 should result in the same limit as 299. Just a random thought I had watching.
Savage buildzoid is best buildzoid.
I hate all the auto OC features and boost algorithms on AMD and Intel. I went from Sandy Bridge E to 9th gen coffee lake a year ago and that auto config crap is driving me crazy (both are Asus ROG boards) . Even after disabling and setting manual values on all the auto ones (voltages, memory timings up to tertiary timings) and the system is perfectly stable after torturing it for hours and using it for days.
Somehow whenever there is a major OS or hardware driver update forcing (multiball) reboots settings get ignored or changed resulting in a post fail and then the board retrains the memory (this and other settings were disabled in bios even the switch on the board itself) just F-ing things up even more.
If i'm lucky it stabilizes after several reboots with insane auto voltages set on everything skipping safe boot values. If you would run those settings for a while you'd fry it. I just have to get in bios reload my saved profile to solve it like wtf ???
While with every bios update they claim to stabilise something and better memory support (my kit was officially supported from day one) but in my opinion the auto thing get worse. If it didn't had dual bios i would have bin screwed by the latest one.
I don't render much, but I do a lot of timeline editing
Is the 3900x a better choice? Is it better to manual OC or to let it PBO? (Custom water loop)
@Erotikstudio Winkler GmbH You get 4 Cores more on the 3900X"...
Yes, but for the same power envelope or even higher than the 3950X! Not sure the poster needs the power of the 3900X or the 3950X for that matter, but on a system on for the whole day every day, if the CPU is maxed out, you will actually save money in the longer term with the 3950X due to its greater power efficiency....
Not your fault, the poster asked what's better, but failed to ask better than what?
Lol. Just type in some numbers, try it out, ramble on, confirm it doesn't work, type in some other random numbers and try again, ramble on. Repeat until results lol.
1.0.0.4 is just bad, it's instantly 10C more idle and if you think 33C idle was bad, well it's upto 53C idle with 1004. Sadly now I'm stuck with ABBA until AMD makes 1.0.0.5 that hopefully works right and can finally get possible bios updates too.
For me a max voltage limit would be far more useful than PBO, I'd set that to 1.3V and be a happy camper. I don't want 1.45V for nothing but heat. 3.6ghz is plenty for watching this video or making this comment :) (3600X base clock). AMD logic somehow is MAX voltage MAX boost all the time for everything! need more POWER! "I see 3% load in one thread, engage 1.45V and 4.4ghz!" "background processes need love too" no they don't, they are on background for a reason.
But load is great, if you can do 12x 4.125mhz with 1.312v (Cinebench R15), surely CPU should know how to do 1x 4.125mhz with 1.312v, but Ryzen can't.. It should even do 1.312v 4,4ghz as it's only 3% load, opposed 100%. Now as the CPU is somehow that stupid, having a voltage limit "this is what you get, deal with it" would make the CPU do that 1.3V 4ghz boost, if it can't do full 4.4ghz then do 4.1ghz for internet browsing.
Anyways, thanks for the video, nice to see that PBO stuff as I can't use them, silly AMD locking them behind warranty loss.
How much variety of software have you run at your OC settings vs PBO?
20:03 - Ive noticed with Intel and nvidia their hardware seems to know the limits out of the box where as with AMD it seems to figure it out in realtime with no memory of what CPU has been capable of, it would be interesting if AMD made their hardware recognise what it can do over time so It'll just step down voltage over a while.
Got a 3800x, but dont want to manually overclock, what settings would you recommend for PBO? i am running an aorus pro and 360mm aio
Start with 230 / 230 / EDC 1, +200MHz, Scalar 1x-2x. Disable Cstates! I have also 130-140% on the current capability, llc auto.
I tried alternatives with Cstates enabled and all EDC values between 1 and 25 with my 3950X, but EDC 1 and Cstates disabled works best.
Scalar 1-2x should be a start, to not ramp up temps / volts too high. You could later play around with medium-high llc (some droop) + positive vcore offset, OR with llc high + negative vcore offset. enjoy!
Are you superstitious? You backed down from using 666 PBO limits :P Also ASUS and others were artificially increasing boost higher than stock on 1.0.0.3ABBA so they weren't running at AMD spec. So that could explain the difference here. This info came from Mukmark the HWinfo creator. Also, there has been a number of ASUS specific cases with the C6H/C7H such as PBO limits being frozen on Ryzen Master and HWinfo on anything older than 1.0.0.4. So AGESA isn't a cop-out for shoddy board partners as this was specific to the C6H/C7H only. I don't think you have done enough research on this subject prior to this video. PS I have been banned from that weird AMD meme subreddit, that sub is more toxic than Intel & Nvidia sewer sytem combined
no intially I wanted to punch in 666 for fun but then decided that I don't really want to read the comments that would lead to.
I've had some really bad stock frequencies for my 3950x, insain that in prime 95 it clocks to 3.5ghz and sometimes 3.3ghz
Can I gain performance like that with my 3700x and my aorus ultra? Which PBO settings should I use? The same?
Try PTT200/TDC130/EDC10 it weird but works just fine on my X570 Aorus I Wifi ITX... CB R20 should be 5000+ (my record with watercooling and tuned Ram is 5303)
Check for 1usmus's articles about PBO and OCing Ryzen overall. You get more clock, when the temps are low. I get highest performance on Ryzen r5 3600 on these settings. Offset -0.1V AutoOC 500Mhz.
*_[screeching r/AyyMD noises in the distance]_*
Work at b550?
atleast you have pbo with your cpu , mine does not especially that i am using an x570 aorus elite wifi (latest F11 bios) board with a ryzen 7 2700x
Thank you 👏👏👏
any update on that old pc you found at your parent's place or what ever? max it to the maaaaaax!
What annoys me on my 3950X is the differences between cores 0-7 and 8 - 15 in regards to the boosts. It's 2-300 Mhz difference. Also the only way I can get 4.7 Ghz on a single core and yes it's just one single core out of 16 fixed, is to enable PBO. I'm running an EK Velocity block with 280 + 360 rads and a D5. Yep PBO is weird for sure.
Just being curious... Whats your Mobo and memory timings?
@@downwiththatsortofthing624 I'm just running the XMP profile 16-19-19-19 at 3800. I have Hynix DJR and it's kind of obscure to get good info on timings that work without spending hours messing around. I'm running a GB Aorus X570 Master.
Have you tried both overclocking menus? I thought AMD said they created an AMD sanctioned overclocking menu, but then also let board partners implement their own overclocking menu.
This seems like the type of thing that could be broken in one but not the other.
I wondered why my MSI X570 Unify had two different overclock menus with very little discernible correlation between the two. I wonder which is AMD’s and which is the board’s?
Yeh, PBO really doesn't seem that great to me. On my 3600 I ended up turning it off and overclocking it instead because why the fuck would my CPU boost some core with >=1.4V in idle when legit nothing's going on, shortly spiking my CPU temps to the point where fans ramp up a bit. Have a 1.3V @4200MHz profile and one with 1.1625V @ 4000MHz all-core. Great performance and no pointless boosting and temp spikes.
Same here with a 3700X, I run 1.25V @4100MHz and it's nice and cool at idle, although I still did have to mess with the fan profile since I tend to run high ambient temps in the room and it was still ramping up and down every few seconds (stock cooler). Now all is quiet until the chip actually has some work to do.
My 3600 @1,3v 4100Ghz cant even load to desktop. Tried @1,35v 4100 its unstable too. I must have very bad chip.
Me enabling PBO2 on my 7900X...
255W 5.7Ghz all 12 cores, it barely stays under the fkin 95°C temp limit... like 93.3°C or something.
What's an AGSA?
AGESA is AMDs BIOS releases.
lol on spread sheet / camera, video was very interesting and entertaining
And just before you said it I thought "I hope he has a spreadsheet we could download" 😅
5:19 OMG! We felt that!
Should I unsubscribe and immediately resubscribe just to hit that button again? :D
I've been using Ryzen Master on my none X 3600 on an Asus b450-I motherboard to run at ccx0-4375mhz ccx1-4325mhz 1.38125v. I'm scoring some really good numbers with a 14cas 3600mhz Neo kit
Is that 1.38v override ? If so, then that may degrade your chip pretty quickly.
www.techpowerup.com/forums/threads/help-oc-ryzen-5-3600.262985/
"None of these 3000 chips are actually designed for all-core boost on 6 or 8 cores past 41.5x"
Like I said my 3600 on a stock cooler can do 4.3 with 1.33 vcore and pushed further with a better cooler and per ccx overclocking can do ccx0-4375mhz and ccx1-4325mhz chips will degrade inside 3 months pushing 1.4v or more i know that for a fact but at 1.38125vcore I've not seen an issue I'm still scoring nice and high on everything months later. The problem is Current that is what kills a cpu High voltage is fine if you can cool it and not keep the cpu pegged at 100% at the same time the more cpu you use the less voltage you should throw at the cpu for daily higher clocks. 100% usage plus high voltage = a lot of current. Silicon lottery plays a large roll in all of this though. Some will take more abuse than others and some will clock higher it's luck of the draw. My physics score in Fire strike is 67.24 fps. If you are that worried at all about overclocking I'd advise you to just let it auto boost. I've played with everything but a 3950x and they all will hit atleast 4.3 on 1.38v and its easily cooled at that voltage.
@@joshpashia637 hell, your fried chips pal. Feel free to ignore the people that had their chips drop in max frequency and bet on your luck.
@@DeadNoob451 like I'm worried if a $160 cpu suddenly eats it >.> all these people that have no idea what they are talking about is more like it even Silicon Lottery Themselves sell pre binned chips at 1.325v and everyone here thinks 1.3v is too much LMFAO.
Don't worry, Buildzoid. I don't think I remember the base clocks of any of the chips I've had lol
But what if my fictional superhuman eyes could keep up with the fictional refresh rate of the display and HWInfo?
