Usually, if a vendor's spec sheet for a (SOHO/consumer-grade) motherboard mentions ECC-UDIMM explicitly in its memory compatibility section, and (but this is a more recent development afaict) DOES NOT specify something like "operating in non-ECC mode only" at the same time, then you will have proper ECC (and therefore EDAC and RAS) support in Linux, if the kernel version you have can already deal with ECC on your platform in general.

I would assume your particular motherboard to operate with proper SECDED+-level ECC if you have capable, compatible DIMM, enable ECC mode in the firmware, and boot an OS kernel that can make sense of it all.
