I see. Asus does claim up to 32GB, on their site and manual, but who knows right?
I didn't know about that unbuffered ECC versus registered ECC stuff. Thanks for the links, if worse comes to worse I'll just replace my memory with 16 GB unregistered ECC, like two KVR1333D3E9SK2/8G.
Probably I should have bought a server motherboard, but the ones I saw with G34 sockets didn't support SATA III. Also, my budget just can't afford it right now.
It's a great system, but when I have more dough I'll get something more appropriate. Hopefully those 20-core Terramar chips come out soon.
Thank you for your response.
