Hey there! A few minutes ago, I follow the guide on this Thread: http://forums.macrumors.com/showthread.php?t=1142028 It seems like everyone is happy with the results, but I'm having a problem...the second I click "Apply" to any setting in the Overclock menu, all of my sliders and adjustments snap back to the default. In fact, now that I have installed this tool, it has severely underclocked my graphics card, and I get horrendous performance out of any game I play. I can uninstall it and it works fine again, but I'd love to actually get this to work, and hopefully get a few extra FPS out of my games. Could anyone tell me what I'm doing wrong? It would be much appreciated. Thanks!
