Don't forget that you do need to consider power consumption of the motherboard as well as the processor, as you will be using different ones for each system.

Hopefully, you're lucky enough to be near a Fry's. They have a A2 X2 240 + mobo for $39.99.

Here is some data from a single e5200 that I tested in a Gigabyte G41M-ES2L

2.00ghz (333x06) bios vcore 0.884 OCCT vcore 0.86 Temps 35*c idle 37* loaded
2.33ghz (333x07) bios vcore 0.900 OCCT vcore 0.88 Temps 35*c idle 38* loaded
2.66ghz (333x08) bios vcore 0.948 OCCT vcore 0.93 Temps 35*c idle 42* loaded
3.00ghz (333x09) bios vcore 1.028 OCCT vcore 1.01 Temps 35*c idle 44* loaded
3.33ghz (333x10) bios vcore 1.108 OCCT vcore 1.07 Temps 35*c idle 50* loaded
3.66ghz (333x11) bios vcore 1.188 OCCT vcore 1.15 Temps 35*c idle 60* loaded
4.00ghz (333x12) bios vcore 1.300 OCCT vcore 1.27 Temps 35*c idle 72* loaded

System was tested with Intel Burn Test then OCCT and then prime at all above speeds.

Currently running it at 3.66ghz with all speedstep functions enabled in bios.

Which heatsink are you using? What is the stock vid of this processor?

The cooler was a whimpy Vortex 752 and the stock vcore was 1.250 idle temps as you can see never went below 35* so pretty sure the thermistors just wouldn't register below that.

If you are talking about power usage, LostCircuits is the best bar none for representing the real power consumption numbers for load and idle. I understand there are many Intel employees, fanboys, and average users alike on this forum, and thus tend to disregard anything from LC, but the fact of the matter is, MS does the best power measurements on the web.

IMO, Lost Circuits is the only review site worth reading and trusting for unbiased information. Michael's site is very much underappreciated. Otherwise, I find forum anecdotes a lot more useful than 99% of what is out there.

I am about a buy a Athlon 245 and Asus motherboard from a member on these forums. According to some screen shots he sent me it can do 2.5ghz with 1.04 volts! Perfect :)
