What does the mobo manual say? Are your memory boards in the correct
banks? It could be the MMU in the Ryzen 7 insists on banks 1 & 2 being
filled before 3 & 4 while the 5 isn't so fussy.
I don't know about this, not having this sort of problem before, but I
do know from building my own systems that the memory boards need to be
paired up correctly, however you define "correct" ...
