I always kept VTT, PLL and NB very low on this chip. Never needed them actually. Funny you mention FSB cuz I'm thinking somehow it could be that. The night I was benching (i'm positive the change occured that night) I had the FSB up at 540 - 550 for a bunch of runs of superPi 32m, 1m and some 3dmark, but no prime. I had figured I could get away with that heh.

I remember what you're talking about with the dying chip at 600. I think that was CN's chip.
