Thanks so much for helping push me in the right direction.

So far, my new best is listed below. I have yet to set the memory latencies manually (it defaults to even LOOSER timings than 5-5-5-15) AND I am still using probably too much vcore at 1.4000 in the BIOS. I will try to notch that down tonight.

I did small steps on FSB and GMCH while testing 450 x8 (3.60 GHz). Here is a bit of what happened:

(all at 450 x8)
FSB +V.....(G)MCH+V .....Posts? ....WinBoot?
0.10 .........0.100 .........YES .........NO = Windows freezes pre-GUI
0.15 .........0.100 .........YES .........NO = Windows freezes at GUI
0.20 .........0.100 .........YES .........YES = BSOD in under 1 min
0.20 .........0.150 .........YES .........YES = 12 min P95 then hardlock
0.20 .........0.200 .........YES .........YES = 13 min P95 then hardlock
0.20 .........0.250.........YES .........YES = P95 ran for 1hr+

The full details for the last line are below. I was only changing FSB OverVoltage and GMCH OverVoltage in the above tests. (I did do many other tests, not listed).
