hhmmm, well i get a speed of 2ghz at idle with 1.12v
At default settings, your FSB should be about 333.3 MHz and your multi when C1E is enabled will be 6.0 so your total should be about 2000 MHz. With my motherboard I can manually lower the FSB to 266 MHz so my total is about 1600 MHz. In terms of heat output, there is virtually no difference between the two settings.
Thanks for that power chart burebista. I think Tom's Hardware did a similar chart a long time ago where they bypassed everything so they could accurately measure just the CPU wattage. When you put a big air cooler on something like that it's no surprise that the core temperature is only about 5C above the room temperature.
I noticed that the new E0 processors have the ability to enable the C4 power state which previously was reserved for the mobile processors. This should lower power consumption another watt at idle if parts of the processor are going into a deeper snooze mode. The general 65W Intel spec for most Core 2 Duo processors looks pretty conservative.
The Asus software looks like it is showing some realistic power consumption numbers. I have my E8400 in today so I might have to set my MHz and core voltage similar to yours and see what my Kill-a-Watt meter shows for overall system power consumption. The total difference should be a few more watts since it will include extra watts for the chipset, etc.
Edit: My Kill-a-Watt meter shows 127 watts at idle and 165 watts at load running Prime95 small FFTs for a difference of 38 watts. Here are my settings:
LinPack creates more heat than Prime small FFTs so I guess that makes sense. My E8400 isn't a happy camper without some voltage but it ran long enough to get some power usage numbers. Time to go back to 4 GHz with some voltage to keep it
