My system config is: Q9300 P5E X38 4X1 GB Crucial Ballistix 8500 ASUS 4850 Arctic Cooling 7 Pro I'm hoping to get 3.5 GHZ. Right now, I have the Q9300 clocked at 430X7.5 at 333 strap. I bumped up the FSB to 430, I can't pass Prime95 further than this. Edit: This configuration is longer be prime stable. Maybe the AUTO function just changed the voltage.

When I try to increase Nbridge voltage or PLL, I can't boot at all. I read in a review once that this board got up to 500FSB on a quad without increasing any other voltages except CPU. I helped my friend get to 3.5GHZ on a P35 DS3R before, so I'm hoping to get the same or even better. Any help would be appreciated.
