Have you tried Ati Tray Tools? (hardware -> overclock settings)

I don't know what ATI tray tools is - I don't have it under my list of programs, or via CCC, can't see anything in control panel either.

Well since I created this thread I have not been able to solve the problem. I have not been able to force my card to move from idle while in this game.

Infact the game makes it step down to idle. Running another 3D game at the same time as soon as I started COD it dropped to idle.

My card is one of the supported/tested cards. Yet everyone I know with the game and this card has the same issue.

Ok, googled and downloaded ATI tray - complicated, no idea how to use it

Odd that so few cards would have that "force max clock speed" setting?

Maybe it's only on duel GPU cards only?

Right below is a ati tray tool icon.

1. click on it
2. click on hardware
3. click on overclock settings
4. change the clocks to the desired clocks
5. click apply

Thanks very much for posting that, much appreciated.

I had found that screen and I changed it from 500 to 880, clicked ok, and my PC crashed (can't remember, maybe I needed to adjust the voltage too). I haven't been able to run the ATI tray since, so I uninstalled it.

Reading another thread on this subject I'm not sure if you should only increase the clock speed by 1, which just gets it going (for want of a better phrase) and allows it to go up once the game starts. Anyone got it to work?

I also looked at editing the MSIafterburner cfg file, but that's not straightforward either, so I'm going to leave it until after the weekend patch, just in case the developers put something in.

What card do you have? What catalyst do you use?

You should get the normal clocks without editing the voltage.

i use a crossfire of 4850 toxic, and using the latest ATT, i displayed the gpu frequencies while playing.

The primary gpu ramped up to 675 mhz without problem, all normal here, and the second gpu stayed at 500, as is usually the case with games not using the crossfire.

how to overclock my card without crashing my computer???i just downloaded ATI tray but my attempt lead to a fully crash of my rig.how can i know how much a can increase the clocks?
btw: i have a crappy hd 5570 card
