Yes, I finally got directed to MM5. Thanks Guys.

Yes you do g odizzy from going back and forth in the bios trying to figure out how a system can be perfectly stable at a FSB of 333 and then die at 335. I was expecting a bit of a transition between totally stable and quite unstable. I still think I've missed something, particularily because I am also getting low overclockability...3.0 Ghz. I tried ramping the vcore from stock to 1.55 with no apparent difference. I also have dropped some of the other voltages to see where they affect stability. So far they look like they will be close to stock. It all takes a lot of time.
