Hi, everyone. I am new to the Hackintosh community. I am not sure if I am posting in the right forum. I apologize for that.

 

I just got Yosemite (Clover) running on my PC with the following spec:

CPU: Intel Xeon E5-2695 v2

MB: Asus X79-DELUXE

GPU: EVGA GeForce GTX 770 SC 2GB

 

I was checking the performance of my GPU using CUDA-Z and found out that my GPU is only running at PCIe 2.0 speed (80GB/s = 5.0GB/s x 16). My GPU is PCIe 3.0 and the MB supports PCIe 3.0 as well. What am I missing? Thank you.
