Hello everybody, i just setup an ASUS KGPE-D16 with coreboot in my fileserver today.
CPU: Opteron 6380 with newest microcode loaded in coreboot
1x 8GB Hynix DDR3 ECC
1x 8GB Samsung DDR3 ECC
ECC works after you force the linux kernel / the amd_edac module to enable ECC as you can see on this dmesg output :

Is there an NVRAM Option for ECC and should i rebuild coreboot with nvram options enabled ?
