OK i flashed a recompiled version with nvram options enabled.

ECC is enabled by default:
boot_option = Fallback
reboot_counter = 0x0
interleave_chip_selects = Enable
interleave_nodes = Disable
interleave_memory_channels = Enable
max_mem_clock = DDR3-1600
multi_core = Enable
debug_level = Debug
ecc_scrub_rate = 1.28us
slow_cpu = off
nmi = Disable
gart = Enable
power_on_after_fail = On
ECC_memory = Enable
ECC_redirection = Enable
hypertransport_speed_limit = Auto
minimum_memory_voltage = 1.5V
compute_unit_siblings = Enable
cpu_c_states = Enable
cpu_cc6_state = Enable
sata_ahci_mode = Enable
sata_alpm = Disable
dimm_spd_checksum = Enforce
probe_filter = Auto
l3_cache_partitioning = Disable
ieee1394_controller = Enable
iommu = Enable
cpu_core_boost = Enable
ehci_async_data_cache = Enable
experimental_memory_speed_boost = Disable
maximum_p_state_limit = 0xf

Still i need to force the kernel to enable ECC.

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 ?

best regards
