The motherboard manual usually refers to a document that says exactly which 
DIMMs were tested in which configuration and certified for compatibility with 
that motherboard.  I'd check that document (I've seen it for Asus, tyan, and 
supermicro) for ECC dimms.  I have occasionally seen a footnote saying that it 
"worked" but there was no ecc functionality present.

It's the best source of info I'm aware of, for the most part this is only an 
issue on desktop motherboard or really low end single socket motherboards.
