Hello,

Earlier today I built a new PC in advance of the 3080 release.

Specs:

Asus Crosshair VIII Hero WiFi

Ryzen 3900xt

NZXT Kraken M22 CPU cooler

4 x 8 T-Force Xtreem 3200

GT 710 temp graphics card

Problem:

System will not post if all 4 DIMM slots are filled.

Info:

Error code is 0d. Amber DRAM indicator is illuminated. No beep code.

System will boot with any subset of RAM installed. Any one stick will work in any one DIMM slot. Any two or three slots will work. Only fully populated will cause error.

Toubleshooting:

Tested RAM speeds of 1333; 2133; 2400; 3200

Updated BIOS to latest version (2206)

Reseated CPU

Took out temp video card to see if error code changed. It didn't.

Disconnected all case connectors. No change.

​

At this point I'm planning to buy some different memory tomorrow at the closest best buy and see what happens. In the mean time I would like any advise for more troubleshooting.

Thanks,
