SummerRain Posted May 19, 2015 Share Posted May 19, 2015 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. Link to comment Share on other sites More sharing options...
tom.bridges Posted May 20, 2015 Share Posted May 20, 2015 Read this and you will understand why. http://www.intel.com/content/www/us/en/chipsets/performance-chipsets/x79-express-chipset-diagram.html Hint: x79 has no PCIe 3.0. Link to comment Share on other sites More sharing options...
SummerRain Posted May 20, 2015 Author Share Posted May 20, 2015 That's for sandy bridge. Ivy bridge does have PCIe 3.0. However, I did further research and know that nvidia disabled PCIe 3.0 due to unstable performance. Link to comment Share on other sites More sharing options...
