Well I have a simmilar setup as you do when it comes to hardware. Ver 1.11 had problems but ver 1.12 I can run 7/24 and it's fine.

What you should do is download a ram diagnostic tool from www.simmtester.com run it on your system (user the burn in ).

There is a quite a bit of bad ram out there and it can create querky errors, ....

good luck
