Yes, also, if your DRAM supports ECC, try enabling it in the BIOS.
This board should support ECC. Then, enable CONFIG_EDAC_AMD64 and
CONFIG_EDAC_DECODE_MCE to check whether it catches any DRAM errors.

If your DRAM is non-ECC, try consecutively swapping out a DIMM each time
and booting to see whether removing one of the DIMMs makes the errors go
away.

HTH.
