Are you using the stock northbridge heatsink? My QuadGT seems to only like higher FSB (for a quadcore) with a very cool northbridge. I can get to 405fsb with a watercooled northbridge, and 380fsb with a Tt Extreme Spirit on the northbridge.

Another thing is that your PWM mosfets might be getting too hot with the NB heat getting added to them.

This is how I have mine setup.
