I was able to get the QX6800 up and running. Installing the X6800 first then configuring the BIOS options did the trick. It still throws a uCode error on bootup, but it runs with all 4 cores in Prime95. It doesn't perform nearly as well though. The best I could do was 285 FSB with the 5:4 divider (definitely seems to be the best option so far with this P5PE-VM modded BIOS) before it started acting up in either Prime95 or SuperPi. I threw in the PQI TCCD ram and was able to get the timings down to 2.5-3-3-5 (this board also doesn't seem to like CL2 at all).
With the X6800, I was able to reach the same FSB speeds as with the E7600, but the E7600 runs cooler and seems to slightly outperform the X6800 with the higher bus/clock speeds.
I have a feeling the QX6800 will do better with the Asrock 4CoreDual-VSTA once I start messing with that. I've read on other forums people using QX9650 on that board, but I don't see how it's possible to reach 1333MHz bus speed with that VIA chipset, even with DDR2 ram.
