I try to build a server using ASRock ROMED8-NL and EPYC 7502P. However, the system refuses to post. Dr Debug shows the following codes:
14 -> 15 -> CC -> C2 -> b3 -> 22
to get stuck at 22, which stands for OEM pre-memory initialization codes.
This is not a faulty RAM issue since I tested three different RAMs (QVL) individually on all modules.
I also re-installed the CPU three times, but the error is still the same. I cleared CMOS for each try, but no luck.
The possible problems can be faulty CPU or motherboard, but which one? Should I return both?
What can be my next step?
