I have ECC RAM installed on my Gigabyte B550I system. dmidecode shows the 72 bit width (Total Width: 72 bits) and dmesg | grep -i EDAC does show a bunch of info suggesting ECC is enabled. But this command's output is empty:
No Memory errors.
No PCIe AER errors.
No Extlog errors.
No MCE errors.
Do I need to enable something so these errors get logged or have I been misled by dmidecode and dmesg?
