I have two X2-3800's. One is a Manchester Core on an Asus A8N-E motherboard and the other is a Toledo Core on an ECS KA1-MVP motherboard. I am trying to determine why the readings for the core temperatures seems to be so whacked out. I am using Everest and Coretemp programs to monitor the temps and this is what I get.

I can't figure out why Coretemp is telling me that the core is actually cooler than the CPU temp on the Toledo but is the other way around on the Manchester. It seems to me that the coretemp is measured on the silicon die itself. Where does the CPU temp come from? Does the motherboard take the core temp and calculate what the case temperature should be? AMD specifies maximum temps as a case temperature but doesn't seem to say what the corresponding core temperature would be.

If someone could look at the attached screenshots and help me solve the mystery it would be appreciated. I just want to make sure I amnot cooking something. Both computers are 100% Prime95 stable.

Looks like the temp for the core and the CPU temp are mixed up. Look at CPU temp for the core and core temp for the CPU temp apparantly
