Of course the A8V is no server board. So the limitations by design will prevent a couple of pitfalls that were otherwise possible. If the original poster is going to buy a server board/system, he should carefully collect information regarding the whole environment he is about to set up. Besides, you should take a look on the compatibilty list again, counting the number of server boards with chipsets that can address up to 32 GB of RAM ;) Cheers, vt
