Real Temp - New temp program for Intel Core processors

[TL1000S]

@Unclewebb:
Excellent documentaion of your work/research.

It would be interesting to do the same exercise provided I got me an IR-meter.

So far I have concluded that my E8400 must be totally wrong regarding DTS/TjMax settings.
There is no way Core0 can be 11 degrees @ 1.33VCore (idle) as reported by Realtemp assuming TjMAx=95.
The DTS for Core1 we can conclude is "stuck"/malfunctioning (see previous posts).

I think you will have to test quite a few E8n00, Q6n50, E4n00, E21n0 before concluding anything regarding a "pattern" between observed temp using IR-meter related to a certain TjMax offset.
Ideally there should be a pattern as there should not be significant deviation between CPU's on a wafer/different wafers using the same production technology.
But clearly we regulary see "batches" of "hot" vs "cold" versions of a given CPU (ie Q6600 B3 vs Q6600 G0).

But clearly we regulary see "batches" of "hot" vs "cold" versions of a given CPU (ie Q6600 B3 vs Q6600 G0).

Intel explains that as "the higher thermal solution performance of the Intel® Core™ processors" for explaining the higher tcase revisions of same processor.

For example, E4x00 comes in two flavors,
CPUID 6F6 or 6F2 with tcase 60C
and the higher thermal version CPUID 6FD or 6FB with tcase 72C

Q6600 G0 stepping has tcase 72C
Q6600 B stepping has tcase 61C.

Since Tjmax=tcase +theta(core-case)xTDP, it is likely that the B stepping Q6600 and others with tcases in 60 have tjmaxs lower than those with tcases in 72 range.

Someone with E4x00 with tcase of 72 needs to check IR reading to compare with IR reading of Unclewebbs as he has the 60C tcase version. Same for GO versus B stepping quads. Given theta(core-tcase) is likely not that different, it would suggest a 10+ difference in tjmax, hence cause the B stepping quads to possibly read temps artificially too high. But wont know for sure til someone IR's one.
