Real Temp - New temp program for Intel Core processors

[rge]

Hello there,

It looks like they didn't disclose anything. Just a point of reference for further research. A target Tj (desired?) which is individually calibrated for each unit. You can stick about that point, but merely can set it as a fixed value in RealTemp or any other monitoring software...

And... I don't see any information about PDC 2000 series, so I'm still stuck with my L2 stepping. Seems I'll have definitely downclock and undervolt, put the HS off and measure the Tcase with a multimeter...

And as for multimeters, guys... I don't have an IR gun and I will have to use my multimeter for temperature measurements. But I am afraid of doing that. AFAIK the temperature probes have something in common with conductivity. Do you think it's safe to place such a probe on an IHS?

It is fine to touch a multimeter probe on IHS...but you will not get accurate temps that way. I bought one, paid extra for calibration, only to find that out. There are surface temp probes for few thousand...little expensive for the task...but thermocouples are going to read way low as most of it is measuring temp of air when touching to a surface. Which is why intel embeds them in the IHS, and even then have to calibrate them.

I'm really confused now what values to use for the DTS reading offset.
Tj Target probably not so why do they publish these values? Is Tj,max different from that Tj Target (never seen such a naming in documents)?

Moreover:
- the inaccuracy of DTS readings raises at lower temps
- certain CPUs report invalid DTS temperature below 50 C
- DTS was never meant to be used for temp reporting - just to catch the hot point (value -> 0)

Is it really usable, or better forget all DTS on CPUs prior to Nehalem ??
