I think i may have discovered a way to sorta overclock my mac...I just want to confirm this with someone else, and how far I could OC the CPU if I ever needed to. I have an early 09 mb (a1181) with the nvidia 9400m, 2.0ghz Intel C2D, running Win7 32 bit. I was lookin around in my nvidia control panel, and I came across, under performance, a menu called device settings. And under that had options to increase or decrease the FSB of my processor. Mine currently runs at about ~266 mhz. Knowing that macs get notoriously hot, and that OC can fry components, I decided to take it up by 5% (280mhz) and hit apply. I went to my program that gives specs on everything (everest ultimate ed.) and went to the OC section, and to my surprise, it was running at 2.1ghz! I've read all over that it's impossible to OC macs, but can someone confirm what i have found..?
