Normally it is not necessary to search though 175 or more motherboards for AMD to find which have ECC support.


The empiric rule for which I have not noticed exceptions yet is that if you want ECC, you must buy either any ASRock MB or any ASUS workstation MB (so for ASUS only those clearly described as "workstation").

So just looking at the names of the MBs in a list, you know whether they support ECC or not, before verifying the detailed specifications.

The ASUS WS MBs have the additional bonus of lacking any gaming-oriented features that might be useless in a professional setting.
