My E6600/P5W DH will not run stable at 333 FSB (3GHz) with anything less than 1.35 vcore. I can go as high as 320 FSB with vcore on auto. I'm not going to bother pushing any further. There isn't a justifiable return in performane for the hot temps I would get, on air. Hey, it's like I have a X6800 running at stock, for 1/3 the price!
