I would go for corsair or kingston 1333 or 1600 ecc, but to be safe, email asus tech support, as their website has no ram recommendations. Most xeon boards don't require registered ram, just ecc. Ecc unregistered ram will work on both server and desktop boards.
Yeah, no recommendations on their site, probably because the board is kinda new.
I searched for Asus tech support email, but couldn't find it. There's a form which requires product S/Ns and similar, but is there a direct email?
As for ECC, I saw that even ECC itself comes in "buffered"/"unbuffered", "registered"/"unregistered" types ... What are the differences and what should I use?
Yeah I would definitely send them an email and ask what ECC memory they recommend. ECC can be really frustrating and some brands are just straight out not compatible and then you end up wasting time and money RMAing it.
I would recommend reading sections 2.4.2 and particularly 2.4.4 of the manual. This isn't a server motherboard that uses registered memory; therefore it has memory limitations that are clearly explained in the manual.
Damn, didn't know that's already in the manual! Thanks!
Looking at the lists, there's no 12GB (3x4) kits mentioned. However, I looked at Kingston's site, for all similar (but a bit older) Asus WS boards (the one I'm thinking of buying is not yet there).
Anyways, there's a KVR1333D3E9S/4GHB that's "Guaranteed Compatible" (however, it is a KINGSTON site, so ... ).
And then under additional memory, there's KVR1333D3E9SK3/12G, which I assume should be the same thing, just a 3x kit.
Does that mean it should be compatible? Since this new board should only be an upgrade to those older WS board.
P.s.: GhislainG, should I look into buying a strict server motherboard?
