The problem is that it is unsupported, so getting a board where the BIOS can enable it & you can count on it working is a bit of a crap shoot. I had the same problem ~8 years ago when a friend and I built new desktops. You've got to do a lot of manual reading, forum reading and review reading before buying a board. Or buy it locally from a place with a good return policy. This is quite a bit different from server grade kit where ECC is fully supported.
