Hey guys, I've searched all over for the answer to this and have come up empty. I know a couple guys in the MBP refresh gaming thread were able to overclock using Nvidia Tools. I'm not having any luck; the sliders are grayed out and I can't make any changes with system tools 6.06. I've also gotten errors when trying to install Nvidia drivers other than the ones included with Bootcamp. What driver/system tools version are you using to OC? And what settings have you tried? (I'm on Windows 7 64bit) Thanks!
