Things seem to be looking up! I was able to run it at 400FSB, and the RAM is running at 1600Mhz with all 4 sticks. Timings are set to a mere 7-7-7-21 with 1.94v [this RAM supports a max of 2.0v before the warranty is voided out]. As far as system voltage, I got the CPU @ 1.20, the PLL @ 1.50, the termination at @ 1.10, DRAM @ 1.94, NB @ 1.35, SB @ 1.05. I'm happy with those voltages, except for the NB one; does anyone think its a bit high at 1.35v? Please advise.

PS: I had it running from 12am til 7am this morning on Prime95. Had no errors whatsoever.
