Hi guys .
I just build new PC .
R9 9950x
2x32 GB Gskill FlareX5 CL 30 6000
Asus X870 TUF gaming Plus WiFi
I reused old ssd drive with Windows.

I updated the BIOS up to date. Plan to do clean Isntall Windows soon.
I Checked and only 1 slot - A2 is working.
What should I do ? Is this motherboard board issue or CPU?
Can I just leave my PC with just one sticks of RAM?
