Seems like you're doing extrordinarily well Kup. Like others have said, it's not that we don't trust you, but so you can confirm the virtually unbeleivable! The amount of time I've wasted trying to get my board stable at 460+fsb with my old quad, and ~500fsb stable with my current chip is silly, and I'm just speaking for myself! Massive kudos for getting as far as you have, would be great to see higher clocks. Does it still behave if you up the multi?
