q6600 & ECS G31T-M: CoreTemp off?

[weenerdog]

So, I picked up the Fry's bundle the other day (indicated in the title) and wicked up the FSB to 300; ran Prime95, etc. seems stable. I've read the OC guide at the top, and was comfortable with ~60 deg C temps reported by Core Temp 0.96.1 on stock (retail CPU) fan, and an indicated 1.23 volts. Then I fired up SiSandra's environment monitor, and it doesn't show a CPU Temp, only an Auxiliary temp, reading 15-18 deg C lower. I wanted to play with the "SpeedFan" bios setting, so I killed folding, let her idle to stable temps, and rebooted; the BIOS CPU temps were a the same as the SiSandra temps.

GO stepping.

Anyone seen this? Will the Real CPU Temperature please stand up?

Thanks!

Coretemp is correct, the others are wrong by exactly 15C.

See Graysky's sticky thread at the top in this forum, read section 5 in the first post.

Thanks for the quick reply.

Hmm, so the BIOS is wrong? I'd think that CoreTemp would be getting it's data via the BIOS...

Nope, coretemp gets its data from the CPU. I'm not the expert on how or why, you should read the info on coretemps website to convince yourself if you really are interested. Why be educated by anyone but the folks who made the software in the first place?

The BIOS temp (the mobo temp sensors, read by Everest and SpeedFan) measures TCase, which is often 15C cooler than Tcore, which is what CoreTemp measures.
