Real Temp - New temp program for Intel Core processors

[unclewebb]

Furiøùs: When I was originally writing the Test Sensors feature I was using a 45nm E8400 at about 4050 MHz and not too much core voltage. With additional overclocking and core voltage you will get bigger changes in temperature during this test. My Q6600 goes up about 10 degrees per core during this test at 3305 MHz and 1.40 volts. At the more typical 3600 MHz and 1.50 volts or so, it's going to be jumping more than that.

I think a difference between cores in a dual core of about 3 is pretty normal but I'm not sure what causes that. In theory, if both cores are given the same work load you would expect that both cores would heat up an equal amount but that isn't always the case. It could have something to do with how you applied the thermal paste or how Intel soldered the IHS to the cores or how you screwed down your heat sink or if both surfaces are perfectly flat and square to each other or who knows. The test was basically designed to find sensors that are getting stuck which is too common in the first batch of E8x00 processors. Uneven idle temps and zero movement in this test is a very good sign of a stuck sensor that won't provide accurate idle temps.

fgw: Thanks for that post. The first C in eax shows that bit 30 of MSR 0xEE is set in your E4300. It's also set in my E6400 and E2160 which both have a proven TjMax=85C. More evidence that the E4300 probably doesn't have a TjMax=100C but I still need to test one to confirm this.

emoners: Version 2.25 is beta at the moment and I'm working on individual idle calibration for each core which seems to be a necessity for many Quad core processors. In the pic I posted above you will see that even though the data coming directly from the DTS sensors ( Distance to TjMax ) is inconsistent, the reported core temps are much closer. I'll update the first picture in this thread when it is ready to be downloaded.

ken: Have you ever tried running your B3 at low MHz and low core voltage like 1600 MHz and 1.10 volts to see how your reported core temperatures compare to your room temperature? If someone with a B3 could do that it might help prove what TjMax really is for the B3. Either that or maybe I could trade my G0 straight across for a B3. Any takers?

For comparison, my G0 Q6600 at 3305 MHz and 1.416 volts idles at a calibrated 30C in a closed case with a Tuniq Tower on low speed with a room temperature of about 18C.
