I seem to be having some issues with overclocking my laptop's 8600M GS so I can run Left 4 Dead better.

I've tried using ATITool, RivaTune, and nTune. All have failed to make my OC stick. I can however change the clock of the low power mode for the card. As soon as I load up a full screen game though it goes to high power which is set to 400mhz/400mhz.

Any ideas on what drivers I should be using or how to get this OCing to work?

Don't change the low power setting.

Agreed. Bad idea. I wouldn't recommend overclocking a GPU in a laptop due to cooling issues. Your card is probably downclocking itself back to stock because the temps get too high. The woes of laptop gaming...

It should be pretty straight forward with the latest Nvidia mobile drivers. No need for ATI tool, rivatuner or Ntune.

Load up the Nvidia Control Panel then goto the Performance tab. You can unlock this section by agreeing to the terms & conditions. After that you wil get to a window displaying sliders for core/memory/shaders etc, click 'custom' and then move the sliders to the desired clocks. Then click 'apply'.

If your settings are too high they will reset, you just have to tweak a bit and then test with 3dmark or a similiar program

Overclocking mobile GPU's isn't as bad as you think.

I have mine overclocked pretty high and the temps never exceed 65c

No... Lol.

It was the version of firmware I was using.

I now have it overclocked to 650/550 and it runs fine, doesn't get above 75C even after hours of testing.
