Actually, it may be 92.
The Intel Bone Trail and Bad Axe 2 motherboards come with Andigilog aSC7621 sensor chips that are wired to the processor PECI bus. So not only do they read the standard diode but they also get what the processor is reporting on the bus. If you check Intel's presentation from the other day you'll see how that relates to the DTS temps.
Anyway, one of the temps reported on the bus SEEMS to be the TjMax. For my E6700s and Q6600s, it's always 92 which fits perfectly with what the diode and DTS temps report. For instance, on my Q6600 crunchers that are running full blast 24x7, the diode temp is steady at 52c, the DTS from the MSR reads 40, PECI reports processor temp as -40 and the TjMax as 92. If I let the machine idle for a while, the diode drops to 34, DTS via MSR reads 58 and PECI reports -58 for the processor temp and .... 92 for the TjMax.
On my Q9300, PECI reports TjMax at 84 and the math works exactly as it does for the E6700s and Q6600s.
I'm going to test my E6850 and E8500 tonight.
