Exactly: mine went to 3Ghz as soon as I had Windows installed, but I cant be bothered messing around to see if 3.1/3.2/whatever will work perfectly or not either.600Mhz for free eh. I'm semi convinced that it can go further, but I'm not that pressed to find out. I'm not after the last 3% I can get out of it, whereas an insta-25% jump is indeed worth the effort tbh
