gtj, would you mind telling me the voltage settings you used at 400fsb?

Last night I finally started to move over stock volts, which let me go up to an fsb of 360 completely stable. I bumped vMCH and vFSB up two notches, to 1.575 and 1.300 respectively, and bumped my vCore up to 1.400. First test I tried an FSB of 370 .... went right into Vista, ran OCCT and passed with no problems.

Then I upped the FSB to 380 ... Vista was no problem, and I passed an hour of Orthos, but failed OCCT at around the 7-minutes-remaining mark.

Just wondering which voltage you used to hit the 400 FSB. My apartment was very hot last night at around 28c ambient, and my idle temps rose about 4c, with the load temps for the two cores hitting 56c in Orthos/OCCT. Think I still have some headroom to work with.
