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...
ASUS Crosshair VIII
AMD Ryzen 9 5950X
Trident-Z Royal 32GB 4000Mhz 15-16-16-36 1.5v
Samsung Evo 2TB M.2
ASUS Thor 1200W
EK custom open loop cooling
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?
