burebista: In Vista, it's still not possible to get it to Start Minimized 100% of the time with the Task Bar option enabled. It's a lot better than what it was and without TaskBar enabled, like you and I use, it should be 100% now. One more tweak and I'll be happy. It will have to briefly flash on the screen when it starts with Task Bar enabled but at least it will work OK. What works in XP, works a little differently in Vista. Thanks for all your help testing.

Captn: Orthos is just a fancy GUI wrapped around the Prime95 code. I prefer Prime95 version 25.6 because I think it's a more recent version of Prime95 than what Orthos is using.

I put a link to the RealTemp docs in the post just above yours Captn. It talks about the Calibration procedure there.

For Prime testing an E8400 at 3600 MHz I'd start at 1.20 volts as reported by CPU-z under Prime load. I think the really good 45nm Dual Cores can run at 4000 MHz with about 1.25 volts so for less MHz you might be Prime stable with about 1.20 volts.
