Maybe unclewebb wont need the sensor adjustment for DTS that is supposed to be used in some 1st quarter and 2nd quarter 45nm intel cpus, if indeed it is as accurate as claimed, 1.5C between 40 and 120C, but that of course assumes the diodes it is reading is going to be linear over a wide range as well.
As many know, there are several transistors on each core that function as diodes/thermal sensors which are scanned by the DTS on chip which records the highest as core temp. (slide 22) http://download.intel.com/technology...forum_2006.pdf
National Semiconductor has illustrated some of problems of 45nm DTS reporting, using their competitors that apparently report significant temp inaccuracies http://www.national.com/appinfo/temp.../trutherm.html
While obviously biased, it does offer the point of more problematic 45nm temp reporting. Though they have supplied chips before on 65 and 90 nm, this is probably price/contract bids as to who supplies what, and this DTS for 45nm is supposedly relatively new and will report temp 11bit digitally.
Dont suppose anyone knows of a register that will report which DTS is employed on a cpu? I was trying to see if that DTS is going to be the solution or if it was already employed and not living up to its claim.
