I ran smbios and for the memory-related section I saw the following:

Might be time to check (1) my current BIOS settings, even though I felt sure
ECC was enabled in the BIOS already, and (2) check for a newer BIOS update. A
pity, as the machine has been rock-solid so far, and I don't like changing
stable BIOSes...
