In Boot Camp, I overclocked my 512MB vRAM NVIDIA 9600M GT to 750/1180/990 to play games. I want to do the same thing to run games like Team Fortress 2 through Steam while booted into Windows. Temperatures in Windows were stable at 99 degrees Celsius. Can anyone tell me how to overclock the 9600M GT in Mac OS X with a software utility? Thanks.

99C is really hot!
Yes it is. I wouldn't overclock a laptop GPU, there isn't enough air flow as it is, pushing the GPU beyond stock frequencies doesn't really do much except increase temps.

99C is really pushing the GPU's temperature limits. Most desktop graphics cards have a max temp between 100-110C. So 99C in a laptop GPU... thats really pushing it.

I recommend reading up on GPU temp limits just so you can get an idea of what I'm recommending. Naturally GPU's run hotter than CPU's, but they have a limit, just keep that in mind.

Besides the fact it kills your battery, makes the MBP incredibly hot, and voids your warranty..


OC'ing is pretty cool. But on a MBP I don't recommend. It is absolutely not set up for it. Certain laptops are, namely, any laptop that isn't an MBP.

slim enclosure and lots of hardware means it's already pushing the thermal envelope. My MBP feels burning hot playing CSS natively for 30 minutes. I can't imagine a OC.

but if they ever make a native osx OC tool, I'm totally doing it.

Thanks for the replies.

1) Even though my temperatures are extremely high for a laptop, my games have experienced up to a 40% increase in FPS.

2) I never boot into Windows on battery power.

3) NVIDIA says that the maximum for the 9600M GT is around 105 degrees celsius.
