Just some observations: with bios 0801 i was able to boot the system right into windows at 260htt with all voltages at stock apart from Vcore and Vdimm, with bios 1102 anything over 210htt resulted in no boot!

Trying to get my new 2x1GB OCZ Platinums stable i had to set Vdimm manually to 2.1V and Trfc to 195ns for both. I got a few errors in the black slots but none in the yellow ones.

Yesterday i was able to boot at 19,5x200 and run 3d mark06 at just 1.51Vcore, after that it isn't even stable in windows any more at the same settings and still ain't.

I'm still pretty much puzzled by this sytem.
