5950x and PBO overheated something or busted custom loop?

Toldja it was a memory problem.. a few pages back..

Sammy B-Die is the way to fly for an absolutely problem free experience, imo.

Not so sure about that. I finally got around to testing the Corsair DDR4-3600 in a different system and it was fine just as I suspected.

I think I've ruled out the problem being the CPU and RAM as I've been running the old toasted 5950x and Nemix ram in my ML09B with the new B550 Phantom Gaming-ITX/ax for awhile now absolutely no problems since it was built. I took a month or so to enjoy the 4060 low profile and it was just excellent.

The NR200P with the old B550 Phantom Gaming-ITX/ax and newer 5800x and Crucial RAM seemed to be working fine for awhile but recently started to have problems again now that I've had a chance to put some time back on it trying to compare experiences between the 4060LP and RX6700 XT with Horizon Forbidden West.

Graphically messed up BSOD's returned also some SECURITY TPM error and the return of Ryzen Master not displaying telemetry data again. Looking in event log NO WHEA errors of any kind but a lot of app crashes related to an AMD process that must be supplying data to Ryzen Master, also Samsung Magician, and some Windows services crashing too. The system now refuses to apply the latest windows updates for some reason too.

At this point I'm going to try securing erasing the NVMe and do a complete fresh install.

So an update on the old B550 Phantom Gaming-ITX/ax (2 or 3 yrs old now) in my NR200P. The fresh OS install helped smooth out a lot of problems as I think it had crashed so many times the installation got messed up. The only issue remining was applications kept crashing randomly mostly when the computer was near idle workloads. I managed to finally get it stable again by adjusting the LLC for vcore and SOC to mid levels and changing some voltages. Looking back I almost can't believe I had been dealing with this since around Nov 2023.
SOC=1.2v, CLDO VDDP=auto at 1.0979v, CLDO VDDG CCD=auto at 0.9976v, CLDO VDDG IOD=auto at 1.0979v

Interestingly enough the new B550 Phantom Gaming-ITX/ax in my ML09B which has never had a problem also had similar voltages just on full auto and mid settings for LLC.
SOC=auto at 1.0v, CLDO VDDP=auto at 1.0979v, CLDO VDDG CCD=auto at 0.9976v, CLDO VDDG IOD=auto at 1.0979v

At this point all my hardware is working including the old ram and cpu.

The B550 Phantom Gaming-ITX/ax just has some kind of quirky VRM I guess.

Case closed.

As for the other project taking a second look at thermals using the replacement Master SLI/ac I got on ebay - at this point I just don't have the time and I'm going to abandon that project.
