Mjag01 Posted January 29, 2013 Posted January 29, 2013 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. Quote
Fiery Posted January 29, 2013 Posted January 29, 2013 Certain video adapters use power management tricks that lower PCI-E speeds when the card is at idle. Try to run a 3D application, and look at the bus speeds while that is running. Alternatively, you can try using the GPU subtest of the AIDA64 System Stability Test (AIDA64 / main menu / Tools / System Stability Test). Regards, Fiery Quote
Mjag01 Posted January 30, 2013 Author Posted January 30, 2013 Thanks for the info. Understand now that nVidia is not supporting pci-e 3 and their patch only works on older driver version. Quote
