Intel Core Processor Gen3 Memory Data Sheet

RShuf — Mon, 25 Jun 2018 15:41:05 GMT

The later generations have data sheets posted for their memory locations. Does anybody know where the memory locations guide for the 3rd Generation Intel Core Processors is? I am specifically trying to find the memory address for the temperature sensor in the processor.

Hello Rashuff,

Thank you for joining the Intel Community Support.

I understand that you would like to find the memory address for the temperature sensor in the processor.

Could you please let us know if you are developing hardware/software?

Is there a specific reason why you would like to get this information? This will allow us to address your question properly.

I am developing Software. I want the address for the temperature sensor so I can monitor the temperature.

I saw the Thermal Monitor Locations (TM1 & TM2), but I was hoping to read the specific temperature.

The processor's temperature configuration (Tcontrol Offset and Tjmax values) can be read from the IA32_TEMP_TARGET Model-Specific Register (MSR). The processor's per-Core thermal status and temperature readings can be read via the IA32_THERM_STATUS MSR. Finally, the package-level thermal status and temperature reading can be read via the IA32_PACKAGE_THERM_STATUS MSR. All of these MSRs and their access are discussed in Volumes 3 and 4 of the https://software.intel.com/en-us/articles/intel-sdm Intel® 64 and IA-32 Architectures Software Developer Manuals.

Hope this helps,

Thank you for the response, this is extremely helpful. Both the IA32_THERM_STATUS MSR and the IA32_PACKAGE_THERM_STATUS MSR reference the Package TCC (Thermal Control Circuitry) Activation Temperature; do you know where this information specific to the 3rd Gen core Processor can be found?

I checked the 3rd Gen DataSheet.

The Thermal and Mechanical Guidelines for this processor(3rd gen) is not posted online(link does not work), I did not know if it was supposed to be in there.

The TCC Activation Temperature is (also) the Maximum Junction Temperature (Tjmax). You read its value from the IA32_TEMP_TARGET MSR.

Yea, there always seems to be a couple of links on this page that are broken. Could the ICS folks (intel_corp) please request that these links be fixed. We are talking about this page: https://www.intel.com/content/www/us/en/processors/core/core-technical-resources.html Intel® Core™ Processors Technical Resources.
