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.
