Sabertooth 990fx and ecc ram

Hello. I'm looking to buy ecc ram and wonder if it will work on this motherboard. Here's my current setup:

Sabertooth 990fx
AMD fx-8150
16 Gb Corsair Vengeance 1600
(I think the other parts aren't that relevant)

I'd like to switch my ram to 32 Gb, specifically:

Wintec 32GB (4 x 8GB) 240-Pin DDR3 SDRAM ECC Registered DDR3 1333 (PC3 10666) Server Memory Model 3RSH13339R5H-32GQ

The reason is I'm running this system as a 24/7 server. I got this setup because the price of the motherboard+cpu was cheaper than just the 6220 opteron cpu, while really I think the fx-8150 is a better chip.

The ram is not listed as "qualified vendor", but I don't see any 8 gb ram chips on that list, and no ecc chips either, while the motherboard is listed as ECC compatible, with up to 32 Gb ram.

Anybody have an idea?

That motherboard won't support ECC Registered modules. http://www.servethehome.com/unbuffered-registered-ecc-m...

http://shop.kingston.com/partsinfo.aspx?ktcpartno=KVR13... Kingston claim that the Sabertooth 990fx only supports 16GB of memory: http://shop.kingston.com/modelsinfo.aspx?SysID=71926&mf... You should contact Asus to clarify memory support; but a server motherboard might have been more appropriate for your requirements.

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.

Yep, no Server ram for you. I have the same motherboard.... Also if you need ram and want to make your computer a server. Regular Desktop ram will be fine
