CPU load was stressed with Prime 95 25.5 small FFTs.
3.60 GHz, 1.25625V, 75W idle / 121W load
3.0 GHz, 1.2250V, 74W idle / 105W load
3.0GHz, 1.150V, 73W idle / 107W load
3.0GHz, 1.10V, 73W idle / 95W load (-0.1V on RAM)
On that last run the Vdroop was 1.06V.. is the Norway guy measureing bios voltage or Vdroop?
I've finally had time to do tests as well, e8400/ultima-90/radeon 3870/antec solo. I have a 7v 1200rpm slipstream exhausting, and a 1200rpm s-flex on the ultima 90. My default voltage is 1.225v.
[email protected] and
[email protected] are the mininum voltages my system can handle without crashing or giving prime95 errors.
I used prime95's "in-place large FFTs"
3.6 ghz, 1.2250v, 77w/125w.
3.0 ghz, 1.2250v, 73w/113w. (stock setting)

I don't really trust these temperature readings, especially the low-end numbers, since I think my room temp is around 21, but there you go.
Oh, also, when I say 1.225v, cpuid actually reports 1.216v, and when I say 1.0375v, cpuid actually reports 1.024v.
By the way, Vista 64 is a pain in the butt. neither easytune nor rmclock work properly because they use drivers that are unsigned.
