What does the voltage droop to under load when LLC is set to Auto?
Are you sure that Max LLC is the high end of the spectrum?
Depending on vendor sometimes LLC1 is the high end of the spectrum. IOW reversed scales from other vendors.
You need to observe what the actual Vcpu under load deviates from the set cpu VID in the BIOS.
You are still running way too high a voltage for just a 4125Mhz core clock for a 3950X
I was running a 1.30V VID set in the BIOS and resulting with a 1.27V BOINC load at 4275Mhz on my 3950X with a LLC3 on the cpu and the SoC in the BIOS. LLC3 on my C7H is the middle range of the LLC settings.
As you can see that amounts to only 30mV of droop under load. Temps were in the low 80's, high 70's
No, it's his user name on his Moonglow computer via the terminal in Linux.
But it IS an idea ;) so I guess I got one ideal response....

The Asus b350-f Motherboard only offers "auto", standard and high as LLC choices.
I tried using the cpu offset voltage and apparently don't understand it since it wouldn't boot.
I have (probably) managed to get the CPU Over Clocked to 42.25 GHz without it crashing as soon as I started up BOINC. This is with the CPU voltage set on "auto". After I give it a run for a while I will switch the volt to a fixed 1.41 which is what "auto" is currently running. If that works, I will start stepping the voltage down to 1.40 etc. Until it crashes again.
That is probably the best I can manage on this MB.

I have (probably) managed to get the CPU Over Clocked to 42.25 GHz without it crashing as soon as I started up BOINC.
I tried to run reduced voltage and the BOINC software was failing (come back at all the applications have been terminated but system apparently hasn't rebooted).
I am now set at 41.75 GHz and the CPU volts on "auto" with the LLC set to "high" and the power phase set to "optimum".
That seems to be giving me 1.38 volts. I may/may not experiment with it some more. When the experiments fail I lose production which I don't like.

Still have no clue what your voltage is in the BIOS. When you set to Auto, is there not a readback voltage shown that Auto creates?
Is there not an option to take the voltage off Auto and set to Manual?
Yes, and that is what I have been playing with. Lets say the "auto" says 1.43 volts. If you set manual to 1.43 volts "sensors" is often reporting 1.41 volts. Even with LLC set to high.
It doesn't seem to be completely linear. I will play some more tomorrow but right now I want it to crunch all night....

The reason I have a Epyc 7401p is because it was significantly cheaper than the 7402 CPU.
I am seeing a 7601 for under $400 (32c/64t, 2.2 GHz). More cores/threads, faster processing than a 7401. What is not to like?

This is after all an ASUS mobo and they all have the same BIOS layout as far as I know.
Can you post a image of the BIOS for your cpu settings page with a screenshot.
