I've been trying unsuccessfully to get ECC error reporting to work in Debian 11. The hardware configuration is as follows:

  • MB: ASRock X570 Pro4
  • CPU: Ryzen 7 PRO 5750G
  • RAM: Kingston KSM26ED8/32ME (x2)

All of these support ECC, and ECC is also enabled in the UEFI settings.

Here are some commands I've tried:

# dmesg | grep -i edac
[    0.331589] EDAC MC: Ver: 3.0.0

# edac-util --status
edac-util: EDAC drivers loaded. No memory controllers found

# lsmod | grep edac
edac_mce_amd           32768  0

# ls /sys/devices/system/edac/mc
power  subsystem  uevent

# modprobe amd64_edac_mod 
modprobe: ERROR: could not insert 'amd64_edac_mod': No such device

# modprobe amd64_edac_mod ecc_enable_override=1
modprobe: ERROR: could not insert 'amd64_edac_mod': No such device

# ras-mc-ctl --status
ras-mc-ctl: drivers not loaded.

Is there anything else I could try?
