Making your PCI-E 3.0 card run at 3.0?

post #1 of 6
Thread Starter 
I have a PCI-E 3.0 HD 7870 but when I use GPU-Z it says I have a PCI-Express 3.0 running at PCI-Express 3.0. When I had my HD 7770 on my Z77 board I did a simple registery edit and it ran @ 3.0 Speeds. I am using Windows 8 Release Preview and I did the registery edit - but it still runs @ 2.0. How can I fix this? YES I know it doesn't do anything performance wise...

Did you check GPU-Z while you were running a GPU intensive application? I'm not aware that you actually have to edit registry entries to get a card to run at PCIe 3.0 on a PCIe 3.0 board...

YES - Newest BIOS and I did run the program built into GPU-Z to make it run @ 3.0 but it only goes up from 1.1 to 2.0 when running it.
