Hi, is it normal that TOM2 is 0 on the M4A785T-M mainboard?
Here are the logs from coreboot:
--------------------------------------------
Sysmem TOM = 0_80000000
Sysmem TOM2 = 0_0
[...]

And from the linux kernel:
-----------------------------------
[ 0.312294] mtrr: your CPUs had inconsistent variable MTRR settings
[ 0.312295] mtrr: probably your BIOS does not setup all CPUs.
