very nice haste, thanks for sharing with us. i tried your settings on my opty 170. i was able to boot into winxp, but superpi failed on me, cpu0 failed while cpu1 ran all the way for a 4M test. awesome bandwidth you got there too. 2.97Ghz for 24/7 is not shabby at all. i'm able to boot into winxp at 3Ghz and 3.1Ghz, but not stable at all. i'm happy with 2.9Ghz for now.
