Sucks that you guys got some ty chips. It does make that one guy who was crowing about "water cooling = better OC (and 0.9 less vcore required)" look like a total fool I think that was back one or two pages now.

Still amazes me how much variability we have between batches, just 2 weeks after mine.

techguy - yeah I would definitely do an OS reload. When I was OCing with my ty Q743 chip, I was BSODing and hard-locking all over the place. Pretty sure XP did not like that one bit.
