I am having trouble overclocking my ATI 4870 in the Catalyst Control Center. I tried overclocking it to the 700's mhz, but it says its current GPU is 500 mhz. The Memory clock, I can overclock it all the way up, but not the GPU clock. I dont know why my GPU is not overclocking, but I only have one idea and that is because I have a Gateway. I can't overclock my AMD 8400 Phenom processor which is only pushin 2.1 ghz. Any suggestions?????

the 500mhz speed is the 2d speed. when not doing 3d the gpu slows down to 500 to save power.

Have you tried using Auto-Tune?

I've down clocked mine to 500/450 to keep my system cool, but Auto-Tune rated it to go up to 820/1175.
