Right, so I decided to try and slightly overclock my ATi HD 4670.
I open up CCC (Yes, I know it's not the best OC utility out there, but I just wanted to try.)
And drag the Core Clock slider from 750 Mhz to 800 Mhz. I press apply, and click the "Test custom clocks" button. After about 5 minutes, it passes. I close CCC, and reboot the PC.
Now, according to CCC, the GPU's clock is, indeed, 800 Mhz. But according to GPU-Z, it's still at 750.

Am I supposed to do something else for it to apply?

I'm fucking retarded. I never checked the "Enable Overdrive" box. Just saw it when I looked at that screencap. Rate me dumb, please.

I've got the new Gigabyte version, which uses a Zalman heatsink.
Also, the overclock seemed stable, however, it only gave me a 3 FPS boost. So I went back to the default clock. I'm grabbing a 4770 in a couple of weeks, anyway.
Did you reload gpu-z after you made the changes?

read the op lol
It's ATI's powerplay feature. Launch a game then alt-tab out and see if the clocks are higher.
Same thing happened with my HD4870 except the clock was down to 500mhz for the core, however if I recall there's a method to disable this. Google "Disable ATI Powerplay".
