RealTemp 2.70

I'd be happy to show you my in depth TjMax testing of an E8400 but I originally posted that information on a different forum and I'm no longer able to post links to stuff like that. I thought the U.S. was based on freedom of speech? I thought forums were about sharing information and posting relevant background information to support ones theories but that doesn't seem to apply at the [H]ard forum even after being a long time member while helping hundreds of people with their computer problems.

Might just be a system hiccup, rather than a conspiracy. If you post the URL, we can copy/paste.

The US might be, but this this is a private forum and Kyle can manage it however he wants.

I agree. If he doesn't want me posting links to relevant information that I have posted on other sites then that is fine. I will try to copy and paste it here.

Here's a test I did with my E8400. In my opinion, it doesn't leave a lot of room to argue that TjMax = 105C. That looks impossible to me.

I have an E8400 installed at the moment and it is the whole reason that I decided to write RealTemp. The reported temperatures for it just didn't seem right.

The heatsink is off but I've got a small high speed fan pointing towards the CPU.

Some users might think that without a heatsink attached that core temperatures would be out of control but far from it.

They were dead stable for over 15 minutes which was long enough for SpeedFan to draw a complete graph with only brief moments of the temp going up by 1C and then dropping down again.

After 15 minutes of this it was time to get out the IR thermometer. There was no hurry so I had a chance to scan around until I found the highest temperature which was 38.8C.

CoreTemp is using TjMax=105C and SpeedFan is using TjMax=100C.
RealTemp is using TjMax=95C combined with its exclusive Idle Calibration feature.

Have a good look at those 3 programs and you decide which one seems to be displaying the most honest core temperature.

To believe TjMax=105C, you have to go completely against Intel's own in house testing of their processors at idle.

Some programs like SpeedFan and I believe CoreTemp are using bit 30 of MSR 0xEE to determine TjMax. If that bit is set then TjMax is supposedly 105C for 45nm processors but that bit is not valid for this E8400 and I don't believe it is valid for any desktop processors. That bit was designed to be used for determining TjMax for the mobile processors. If you would like to check your own processor you can use CPU-Z and do a Register Dump to read Model Specific Register (MSR) 0xEE.

This same sort of testing also shows that the previous generation of processors were not TjMax=100C. My Q6600 - G0 is most definitely TjMax=95C.
