I'm not sure what the issue is, i've tried this two times.
First, I download the FA0 vbios update from Gigabyte's website (the one which enables 14gbps). I run the .exe in the folder. It says it successfully patched and asks me to restart my PC. I restart it, check the Radeon software, and it still says I'm only on the 12gbps bios. Am I just doing something wrong? How come it says it's successful but doesn't apply?
