Real Temp - New temp program for Intel Core processors

[unclewebb]

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.

bowman: I'll have to admit that RealTemp was not designed with the Atom N270 in mind. I'll make a few fixes to RealTemp to better support it but I won't be able to do anything with the simple Load meter I'm using. As for Atom performance, it looks pathetic! Here's how my Q6600 does when locked to 1600 MHz.



The single threaded XS Bench does a big calculation and scales very linearly with CPU MHz for pretty much any Core based processor. The Core i7 is about 20% faster at the same clock speed while the Atom looks like a good chip to check your e-mail with.

SFaznSpEEdSTeR: I was just interested in seeing the rest of your Cool Down Test so I could see if core0 and core1 were sticking.

kemo: If you go into the Settings window and click on the Defaults button, it should set your TJMax to 100C. It looks like it is presently set at 95C. The other problem you have is that TJMax is not consistent for both of your cores. I think you should set it to 100/109 for your two cores. As you noticed, core 1 is stuck so it won't be able to give you accurate idle temperatures but when Distance to TJMax is less than 55, your two cores should be well balanced.

colex: When using Vista, I prefer to use the Task Scheduler to add RealTemp to the Start Up area but burebista's method works. In XP you can copy a link to RealTemp.exe into your Startup folder. Edit: This also works in Vista. Go to All Programs -> Startup and copy a link into that folder.
Copying RealTemp.exe won't work since it won't be able to find the WinRing0 driver.

Demthios: You can't calibrate a stuck sensor. Post a screen shot of your CPU Cool Down Test. That's the easiest way for me to get a lot of information about your sensors without having to ask you a lot of questions.

Figured as much. But I also figured you'd want the crown for Intel compatibility so it's another notch in the belt, right? Aside from the two GUI quirks it seems to work fine.

The Core i7 is about 20% faster at the same clock speed while the Atom looks like a good chip to check your e-mail with.

Check e-mail, browse the web, view videos, use Paint.NET.. It works just fine for my mobile purposes

Quite a difference on idle, load seems alright I guess? It was 28, 28, 32, 32 on 2.70 (non-beta).

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.

Apparently my front intake fan has decided to fail which explains why Everest didn't list it in the screen cap. After manually encouraging it to crank over, it doesn't appear to have any impact on the closed case temps.

Now Load Temperatures seems more accurate but still i have never seen TJ-max distance of more than 55 on any of the cores , thanks for the tip
