Asus was the most forth-coming about that. If they mentioned ECC support on a motherboard's specifications page, then it supported ECC and it couldbe enabled, etc. If they didn't, then there was no ECC support. Other manufacturers were far less informative about that. Maybe because it was rare for them to support ECC. E.g. I think that none of Gigabyte AMD motherboards had ECC.
