I will try shot in the dark, since I have no idea about AMD architecture.
Seems that you have 8-memory channels architecture,
And being you I will start reducing amount of memory to see if anything
changes. Would first do 8x 4GB and see what will happen with Coreboot?

Have no idea and original MRC algorithm (number of them) in BIOS is/are the
same as in Coreboot... And I am trying to target the differences!
