Real Temp - New temp program for Intel Core processors

[ptelles]

So is a fair guess for Tj Max +10°C above Target Tj?

There isn't any formula for converting Intel's TJ Target specs to a TJMax number that can be used to give you reasonably accurate core temperatures. TJMax is not a fixed number that Intel is willing to commit to. It can vary from one CPU to the next of the same model. In some cases, it seems to vary from one core to the next within the same CPU.

TJ Target and TJ Max seem to be the same for many processors like most of the E8000 series but the TJ Target numbers that Intel released for the 65 nm processors do seem to be off by 10C for quite a few of them.

For the Xeon E5410, Intel lists the TJ Target as 85C. Run a CPU Cool Down Test to make sure your sensors aren't sticking at low temperatures. Set your CPU to 333 x 6.0 in the bios and drop the core voltage down to 1.10 volts if you can. If you enable C1E and SpeedStep and have Windows set correctly, when your computer is idle it should drop down to somewhere close to these numbers. Run CPU-Z to check your core voltage.

My guess is that TJMax is probably 95C or 100C. Open your case and compare your reported CPU temperature to your room temperature near your CPU.

Post or send me some screen shots and I'll give you my opinion of what I think it is.

Side case panels removed, 6x333, EIST enabled, default CPU voltage of 1.2250V. The D5400XS BIOS doesn't allow for the voltage to be lowered any further.

Tj Max was set to 95°C for Real Temp as well as Everest.

The ambient room temperature was fairly stable @ 25°C.

My idle degrees above ambient appear to be in the +14°C range.

With the case side panels on, overall cpu/mem temps increase approx. another 6°C.
