Interesting, I didn't know the vagp was NB voltage. I wonder if that's what's causing some of my errors as I've had it at default this whole time but I haven't felt the need to bump it up as I haven't experienced any of the windows slowdown at 300fsb w/ my radeon like some people are reporting. Is it unusual for a p4 to be benchable at a given speed (in my case 3.6) but to drop out of prime w/ errors after serveral hours at 300 mhz less (3.3) ? pc ice is going to be getting me a good 2.4 so hopefully I can drop that in soon. I'll see how that does in this board and if things are still flaky, I'll just get a p4c. I REALLY want to like this board, got all the right features and performance at a nice price... we'll see how things go this week.
