Do you guys have this problem too?

It has happened with every graphic over clocking utility that I've used ( ASUS GPU Tweak, MSI AB and Sapphire TriXX ). They'll apply the over clock settings fine and I can see my GPU is successfully running at the specified clock speeds and voltage by viewing GPU Tweak's monitor and playing games or running benchmarks. When I set it back to default clock speeds after gaming and I'm just doing light things on my PC, it works just fine. It's randomly until I try to apply the over clock again when I'm about to start gaming that it doesn't get applied any more. The over clocking utilities say that the GPU is running at the over clocked speeds, but the GPU monitor that GPU Tweak uses says it's running at stock. Also, in-game or benchmarks, the FPS is not as high as when it was over clocked. The only solution to this is to restart my entire system. Anyway to fix this?

GPU: HD 7850
AMD Driver: 12.6

Why do you set it back to normal afterwards? Just leave the overclock running. The card will clock down its voltage and frequency when not in use anyway won't it? At least, my last AMD card did.

I think I've found the problem........ Google Chrome. When I apply the over clock and the GPU only runs at stock speeds as soon as I close Google Chrome, the overclock successfully applies itself...

As mentioned, I don't know why you set it back to stock speeds after gaming, the card should lower the voltage and frequency when under low loads anyway.

Chrome is GPU accelerated, so makes sense that it can't apply the clock while the GFX card is in use.

I've found the problem, it's just when videos are playing whether it's a flash based one on the internet or in a media player. As soon as I exit the video, the clocks are applied. Also, Google Chrome as a whole was the problem too.

Play a video in chrome, right click on it, goto settings and disable gpu acceleration.
