Jeg hadde samme problem på min Crosshair X670E Hero / 7800x3D med aller nyeste 1202 BIOS fra Asus.
Jeg satt EXPO Tweaked i BIOS og trodde alt var på stell. Sjekka BIOS nå og ser at EXPO har satt voltage altfor høyt.
Har endret de manuelt nå. Lurt å sjekke dette ASAP!
Mer info:
I was able to reproduce the problem with me. It is due to the EXPO parameters that AMD specifies. Asus and Gigabyte have implemented these 1:1 without paying attention to the new X3d CCD. While "X" cpus tolerate higher voltages, the X3D die off one after the other because they are much more sensitive.
As soon as Expo is enabled, the CPU SOC and CPU VDDIO/MC voltages increase to 1.36-1.4, sometimes boosting to 1.5V in Windows, causing instant death on the X3d. If you set all voltages manually to the correct values, there are no problems.
