ASUS P8Z68 BIOS update, AI Monitor and temperatures?

Seems that there's this history over the last several years, per confusions about which processor has which TJunction spec, whether SW programmers for RealTemp, CoreTemp and the like have correctly observed the proper spec or use it correctly, etc. etc.

After updating my BIOS to version 0606, I note that the single "CPU" temperature reported by ASU Monitor is about 10C below what it had been before the BIOS update. I could never be sure if programs like HWMonitor, reporting something called "Package" temperature, weren't in fact providing a value for the "T-CASE" referenced by the Intel thermal spec. More puzzling, both the ASUS and other monitoring software were reporting "Package" (or "CPU" temperature) as equal or slightly greater than the highest of the four (i7-2600K) core temperature values.

Has anyone noticed the same thing? I'm wondering if the ASUS software (as well as HWMonitor) had mis-reported what was intended to be "TCASE," and this new temperature reported after the BIOS upgrade represents ASUS' attempt to correct it.

If it's any indicator of TCASE, I can probably over-clock my Sandy Bridge another 100 Mhz -- at least . . . . If I thought it worthwhile to do so . . . .

Here is your answer from the Asus Z68 forum.

"AiSuite II displays the CPU Surface temperature, also known as Tcase, while CoreTemp or Realtemp shows the raw value read out from PECI, which is the core temperature, also known as Tjunction."

You make me feel guilty for not doing enough homework! I've been trying to get confirmation about the relevance of reported "CPU" temperature to the TCASE reference. should have spent more time mining the ASUS forums . . .

So there must have been a bug or miscalculation arising from the earlier BIOS (in conjunct with AI Suite), and the other monitoring options which report "package" temperature must still be in error. If "package" is synonymous with TCASE, a reported value that is equal to or a degree C higher than the highest core value doesn't make sense! Being the cautious type, I stopped pushing my clock-speed and voltage at 4.7 Ghz, leaving me with three "profiles" at 4.6, 4.62 and 4.64Ghz. This confirmation means that I could probably reach 4.7 and do no damage. . . . .

either way, it's good to know! So thanks again, Grumpy!
