So I got an email yesterday. From Benson Inkley, the same person who held the presentation about the DTS at IDF in August.

At IDF Taiwan details about TjMax for all Intel's Core 2 processor line will be revealed.
This includes Core 2 Duo, Quad, Xeons. Both 45nm and 65nm flavors.
QX9775 should be mentioned as well.

Also more information should be revealed about the IA32_TEMPERATURE_TARGET MSR for the Nehalem.

Sounds exciting

Yup, it is.
IDF will be held in October 20-21.

Did this ever happen? It's past October 21 but a quick google didn't turn up anything.

Yeah it happened. But the numbers they provided make no sense.
I'm currently looking into this, so it may take some time until we have an update in that department.

Updates?

Nope

Got an email from Benson, there was an error in the original presentation.
Official release will be made in a few days.
Here is the correct information:

65nm Desktop Dual-Core Processors Stepping: B2 G0

• Intel® Core™2 Duo processor E6000/E4000 series 80 90 °C

• Intel® Core™2 Extreme processor X6800 80 90 °C



65 nm Desktop Quad-Core Processors

• Intel® Core™2 Quad processor Q6000 series 90 90 °C

• Intel® Core™2 Extreme processor QX6000 series 90 90 °C

• Intel® Core™2 Extreme processor QX68XX 80 80 °C

He's still confirming information about the server parts.

I'm still not quite sure about the 80C for the QX68xx parts, but these values look better than the original ones anyway.

Still no word on TjMax for 45nm desktop cpu's?

45nm info has been out for several months already.
Core Temp 0.99.3 has the updated values.
