With a video card, I was able to boot into the Windows desktop at 535MHz x 6 - but it was not stable; I think giving even more voltage to the northbridge would stabilize it, but frankly, I was worried about frying the northbridge. But 500MHz x 8 is stable, with the memory running at 5-5-5-15, when I use a video card.
