Well recently I have gotten 3 dead Duron 700's (2 week 42, one week 27). Just today I got one and its DOA. BTW they were all OEM too. Now you could chalk it up to me being reckless, but I've built many a pc and only recently has this trend occured. I have one working Duron out of 4. The HS/F install is a breeze and the cores/chips showed no signs of physical damage. Guess I may have bad luck.
