Has anyone managed to get a Q6600 to 3ghz by putting the FSB up to 333 or more on air cooling? Im planning on getting one with a antec 900 case and a great zalman cooler, im just wondering if its possible, I dont mind increasing voltage.
Yes it is possible on air but you'll probably need a better cooler than the Zalman. Look for posts by graysky, he has Q6600 clocked to around 3 Ghz. He uses a thermalright 120 ultra and has lapped both heatsink and IHS on the CPU. There's a sticky about it detailing temps he got.
Lapping risky? Not if you're careful and take your time. It's the biggest bang-for-your-buck mod to enhance your cooling potential, and it's cheap. I think lapping my Q6600 and lapping my Ultra-120 Extreme only cost me around $20 for sandpaper and an 8x10 picture glass from Home Depot.
