This is where I am sitting with just minor PBO tweaks. What I have noticed, is if you set some of your PBO settings too high like EDC, PPT they will "Bug" and your chip will just not preform. Try THM Limit of 90, TDC 210, EDC 215, and PPT 500. PPT is way higher than it needs to be, BUT I have noticed this number is funky with AGESA for whatever reason. Do a - Offset on the curve optimizer of 10. Leave the FIT Scaler on Auto or manually set it to 1. The fit scaler is really the thing that will hurt the CPU. Set your CPU Boost Max Freq to +200. Just let me know what happens there.

Looks like your quick tweaks worked. I followed exactly what you posted above and got this result.



Finally forced temps to go up a bit as well. I cool based on air-water delta, so my cooling system never even got going after two runs. Thanks! Gives me a little hope for this board. All core boost seemed to sit just below 4.4 GHz.

Rock and Roll man!!

Also as a quick aside, you can probably Push TDC/EDC to 240 based on those numbers im seeing. But that's up to you if you wanna try and push harder. You can even keep raising your Curve optimizer offset, my fear is you have 2 ragged cores, Core 3 and Core 5 will be your limiters. So if you wanna get crazy you could do Core by core Curve, set those two cores to 10, and move everything else to 20

Last time I ran the Hydra Tool from 1smus, it showed that I actually needed a positive voltage offset of +4 on core 00. The rest were all negative. Core 03 actually called for -24 and Core 05 called for -12. I think I'll run the newest version again tonight.

I like that tool but now it seems everytime I run it I get totally different results. It gets you close though. I suppose it could also be that I am running it after updates.

FWIW, here is what I get on my 5950X under Windows 11 (not sure why C23 reads that as 10... lol) with all the security functions enabled (slightly less than what I got on Win10, but within the margin of reboot error).

PPT = 250W | TDC = 200A | EDC = 160A | Temp limit = 85C | PBO Curve = -25 on all cores, except the top 4 cores on CCD0 and top 2 cores on CCD1 are all -20 (for stability from testing).

Worth noting; I found a EDC above 160A starts to degrade the Single Thread Performance; 160A (for me anyway) was a sweet spot balance between Multi-Thread and Single-Thread performance. And seeing as I game a lot, I prefer this balance over pure MT performance.

That's pretty solid right there.

I re-ran with your settings for power, but I adjusted the curve to match what the Hydra Tool calculated for me.



Notice several cores with either no offset or a positive offset.




Not your numbers, but not bad. It actually ran hotter and used a little more power than when I ran with the settings from GoldChain above. I re-ran CB R23 and actually got 29261 multi-core. Almost got CPU package power up to 230 Watts.

I'd bet the extra power draw is from the positive offsets; but TBH, I think under 100% load, mine pulls a ton of power too, but realistically, that use case rarely happens for me.

You would likely break 30K MT and over 1600 ST if your 2~4 best cores were negative offsets. If the "*" means preferred core, then those positive offsets are killing your ST performance and thermals for boosting.

You could always give a blanket all core -15 offset and see WTF happens... lol. I took a while to test mine core for core with Prime95, but was not bad as I did it while I was working. -20 all core works for me, the cores I got to -25 was just because I could and it was stable. I tried -30 on those same cores; but every so often (maybe once a week or so) my PC would randomly reboot when I was at lunch (low load), so it was not 100% stable that way and I backed off to what I use now.

Well, I finally tore the old system apart and I moved my 5950x over to the server with an Asus Tuf x570 mobo. Same crap. At stock, I'm below 25000 in CB23. Chip pulls around 125 watts and clocks below 3800 all core. It's not the motherboard, it's the CPU. I'll just have to run PBO2 from now on to get it to work. What an anti-clmactic ending. All I can guess is that a powe blip took it out when I had moved it off my UPS that couldn't handle the power. Thanks for all the info guys.

At least with PBO it seems to work within the average range of a 5950X for you... That's so odd in how it is fucked up though, as clearly, it still boosts... lol.

Yeah, kind of strange watching a 3900x boost to higher clocks than a 5950x when both are set to stock.

Kind of like getting a scratch on a new car, now I guess I have license to rag it out.

Yeah, that's why I bought the 2 year Micro Center warranty on mine. I knew I was going tp push the hell out of it and figured after 2 years, worst case, I'd just build a new PC again or another 5950X would be much cheaper.

Technically, my 5950x is still under warranty I guess. I have overclocked it though.

Hello all, I've been reading this thread to troubleshoot some problems I had with Crosshair VIII Hero Wi-Fi & 5950x. And I've come a long way, wanted to share my story - it might help some of you.

I am currently using my second 5950x, the first one would randomly shut down even with voltage offset with any PBO. I RMA'd it, and got a new one. NOTE: I have overclocked my previous 5950x and it was still under warranty, no one asked a thing. The new one works fine. So before anything else, these CPU's have a chance to be faulty.

The current CPU I am using, on the other hand, would not boost up above 4.8 single core and 4.1 multicore with -20 curve optimization. I've been playing with all limits, PPT 395, TTC 220 and EDC 250 was a spot where I didn't get limited by anything. My load temperatures were around 85-90 degrees.

Then I did this;

Got rid of my 240 AIO, got a 360 AIO and made it an intake push configuration.
Found out that my PSU's fan had died (must have been a while ago, Strider Gold 1200w) so that was even causing shutdowns under load, so I got a new solid PSU.
I re-did my entire case for better airflow with new fans, 2x140 top exhaust, 1x120 rear exhaust, 3x120 on the radiator front intake (I was gonna go for push pull with 6 fans, but at the moment it's not needed.)
Using Fan Control V133 I manually adjusted all conditions.
I now sit at 38 idle CPU and 60 moderate load. Full stress test 1 hour ends up with 70 degrees stable.
I noticed higher EDC's, even when letting me breaking a limit, would destroy my core boost. So I am now using PPT 280, TTC 200 and EDC 140.
I am now getting 2950 in Cinebench and my cores boost upto 5150 (I've seen 5200 but that wasn't stable) Also all core boost seems to be around 4450-4525
I found out through trial and error and mostly from the max clock my cores got upto from HWINFO about my best cores and worst cores
Ryzen master helped me with this as well, I found that my cores 3 & 7 are beasts, while my core 13 is not that great.
I adjusted per core curve optimizer



Here are my settings;
PPT 280
TTC 200
EDC 140
PBO Scalar Auto
Per Core Curve Optimizer, with best cores at 28 Negative, worst cores at 15 Negative, others at 20
Max Boost Freq +200

The only other thing I changed from BIOS is the DOCP for my ram (4x8 3600mhz)

My sistem is now stable, cool and single core clocks go upto 5150 on select cores. I'm getting consistent 29000 score in Cinebenc R23(on my daily PC with a lot of background apps). Games run fine and stable. 8 Hours of AIDA64 stability test was fine with no overheating (including GPU and drives)

So, TLDR;
Check other components
Improve cooling
Don't go overboard with EDC, find a low & high performing EDC like 140
Try per core curve optimizer, getting hints from ryzenmaster + HWINFO highest boost achieved

Hope this helps anyone who reads it, GL!
