Question (11/14/2007 12:54:23 PM): I have a retail QX9650, if you have a beta bios to run this CPU, I would be willing to try it, and provide feedback. I am currently running P31, and it will not post with this CPU, I get "--" on the LED panel.
Answered By Christian B (11/15/2007 3:21:19 PM): Mike, For the moment, any 45nm CPU's are not compatible with the 680i SLI motherboard. Once we find if this is a simple BIOS update then we will post it on our forums and download drivers page. EVGA Tech Support
