Without more information about your hardware it's really difficult to offer any practical help.
Could you please post back with FULL system specs, as the issue maybe with something other than the CPU or Motherboard.
Also some history would help.
Are all components new or, are some from previous build(s)?
Was the PC working and then developed this issue or is it a new build?
If the PC was working, what OS are you using and was it a clean install?
I know it is tedious but the more info you can provide the better. I have this board and it is working fine so, comparing notes might help me isolate the problem for you.
I reused only the psu; Everything else was brand new. The system run fine for days, suddenly at a morning switch on, it failed to boot with that error. I then tried a brand new psu.
My system is:
Corsair rm650i (brand new, to test if the previous used Enermax was the cause of the problem)
GA-AX370-Gaming K7
Ryzen 5 1600
Corsair CMK16GX4M2B3200C16 / GSkill TridZ K2 Schede memoria D4 3200 16GB C14
Gigabyte GTX 750ti
The "problem" is that I can rma the mb easly, but I can't rma the cpu that way. So I am just curios about that code. I mean... Does it indicate some failure? Or it is the next error code that should be shown that indicates the real problem? Is it the mb? The cpu?
PS
I never tried any kind of oc.
