I have a asrock 990fx fatality killer mobo and when i enable manual overclock i notice that in my radeon settings my current bus settings says not avaliable when it should say PCI Express 2.0 and when i run the benchmark in gpuz it stuck at pci express speed 1.1 im lost for words here. i want to use bclk to overclock but cant with my video card only running at 1.1 so im stuck using only the muiltipler to overclock as a work around
