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

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.
