Info R7 5800X - BSOD (WHEA) MAYBE THE SOLUTION

[Breadhead1704]

Hello people !

I would like to inform you that I think I managed to '' easily '' stop the BSOD'S caused by generation 5 of RYZEN processors.

I suffered a lot with this kind of problem after purchasing my R7 5800X, I changed many parts of my computer, but nothing worked.

After a lot of research and attempts to change things in the BIOS like voltages, PBO, I found some easy to do settings in the BIOS that might solve your problems.

Obviously, I'm still testing it, but so far I haven't had any issues.

Follows the settings made on my B550 AORUS ELITE ( rev.1.3 )

1 - DISABLE C-STATES
2 - DISABLE COOL N'QUIET
3 - (And most importantly) CHANGE YOUR LLC ( LOAD LINE CALIBRATION ) to TURBO or higher.

To recap, I'm still testing it, but so far I haven't had any issues.

If you changed out everything or almost everything except the CPU and you still had problems, and the only way to get stability was to muck around with the CPU's settings, then I would argue you just happened to be an unlucky one to get a defective CPU.

You shouldn't need to disable all of that to get a semblance of stability.

If those settings help it could mean too low voltage,

Yes, you are probably right, but after a lot of research, I saw that many people have this same problem. I don't believe thousands of people have purchased a processor with the exact same problem as mine. Perhaps it's a problem with the latest BIOS updates or mismanagement of power from the motherboard to the processor.

Yes, indeed it happens. The PBO applied to this processor causes its voltage to vary in an absurd way, so that when the processor enters a state of low utilization, the system simply crashes.

That's what I found too. Although it was working right for long time It started with a sudden, system halts and that same BSOD or restart when when in low CPU demand every few days (PC is on 24/7) but never in benchmarks. Because of that I was going to save on some power and turned on power savings. At first I thought that Curve Optimizer at -30 all core was to blame but even on -10 or none same thing happened. Than I noticed that when at true idle (windows in clean start mode less than 1% usage) voltages drop way bellow 1v . even down to 0.76v, even a small jump in load would cause those problems. Further testing showed also RAM errors which should mean a voltage drop across the board, not only to cores.
Turned off all power savings in BIOS, put LLC to max. Now back to CO -30 and no problems for over a week.
Possible explanation, ever since first Ryzen. MB manufacturers were accused of setting voltages too high causing overheating so they overdone it the other way with auto settings.
