Revision number of CPUID: 000206D7H. Hope this helps. Thanks, Mjag01

Asus Sabertooth x79, 3930K CPU, 64gb Kinston beast at 2133mhz. In bios it states: stepping C1. In AIDA64 it states stepping C2. I have VT-D enabled. Which stepping is true? Any advise will great.

Thanks for the info. Understand now that nVidia is not supporting pci-e 3 and their patch only works on older driver version.

How can I tell if my PCI-E is using 3.0? I'm running Asus Sabertooth X79, 3930K, 32gb DDR-3 @ 2133 and Asus GTX 680 DC2-4gb. When I look at bus type it states: Bus Type PCI Express 2.0 x16 @ 1.1 x16. Should that state: PCI-E 3.0? I have the card in slot 1.
