Intel "server" boards (N440BX or newer) will report and log ECC via
IPMI.  You can find the log via the server entry in the BIOS screens.
The IPMI-aware systems I've seen can be configured to report SERR,
PERR, or both, via NMI.   Lower-end systems should report via NMI.

What kind of motherboard, exactly, is the suspect?
