C8F / BIOS 3204 - IF Stability Issues

[chrismog2_2]

I'm unfortunately still getting some WHEA errors and reboots on the latest BIOS, but only while gaming (specifically FF14) and it takes anywhere between 30-90 minutes. Every other benchmark, stress test, RAM test, etc. in and out of Windows completes fine. Running a dungeon is a good way to trigger it quickly. I tried moving the RAM down to 3200 and IF down to 1600, since those are "supported" per AMD, but that didn't help. Cleared CMOS several times and entered in settings as follows...

- DOCP Standard (to set all the basic timings and voltage for RAM)
- Set RAM and IF to desired frequencies
- Disabled PBO / Fmax
- Manually set tRC (for some reason auto sets it way off)
- Enable Resizable BAR (not sure this has any impact, it was BSODing w/o this setting too)

If I move everything to default and disable both core performance boost and PBO, no BSODs. I've tried some manual VSOC values with varying success, but almost always end up with a BSOD, it just slightly extends or shortens the time... the one time I didn't, VSOC was close to 1.2, and I got a corrected WHEA error per the Windows logs. (Is 1.2+ safe, if I wanted to explore this further?)

CPU: 5950X
Mobo: C8F
RAM: G.Skill F4-3600C16-8GTRS (8GB x4)
GPU: RTX 3090 FE
PSU: Seasonic PRIME TX-1000 (Actually bumped this up from a PRIME Ultra 850W because I thought I had power issues w/ the 3090 drawing too much... guess not)

I am in MISERY after this update...

I was on 2010 and was fine (except for the Fabric clock limit of 1800) I upgraded to 3204 and not only is the boot slow, DOCP is unusable, failing IMMEDIATELY with QCode F9 (Recovery Capsule is not found). restarts, fails again, posts in safe mode. Played with the SoC voltage thinking there may be an issue there... SAME RESULT. I will try a re-flash and then I will roll back... Super annoying...

Hello, F9 is a training code, normally FCLK. Tune IOD VDDG and CCD, too. More often than not, changes to stability in this way between UEFI builds is due to the memory overclock already being somewhat conditional.

Just wanted to put some closure to this thread, I appreciate the advice / assistance but never could land on voltages or settings that 100% stabilized things during games. AMD has agreed to RMA my CPU again, and I've switched back to Intel for the time being. I wanted it to work, but I just don't have the spare time anymore to keep fiddling around with it.

I'm in the same boat, with both a 5800X and a 5900X. Tried multiple sets of RAM, etc. Would you care to share what exactly AMD asks for before they agree to RMA?

They'll ask you for some basic diagnostic reports (dxdiag, msinfo32, etc.) and then make sure you've updated BIOS + chipset and such. And that the usual "supported" non-OC values are being used, including RAM/IF frequencies which will be 3200/1600 or lower.
