What could be the reason I'm confused

Clear CMOS after updating the BIOS. If the 3600 works just fine, the 5600 may be bad.

Could it be the motherboard though? That's what confusing because I have read some fourms where one cpu works and other doesn't and sometimes it's motherboard only

My CMK8GX4M1E3200C16 is not list on the memory support list and I also heard this ram had problems with zen 3 processors. Could it be causing the problem
