TechieWorld,
The monitoring utilities provided by motherboard manufacturers on your Driver DVD reads CPU temperature from BIOS, but
not Core temperature form the heat sources within the Cores. Thermal code can vary greatly between BIOS suppliers and version updates, and can be wrong by up to 30C.
BIOS or CPU temperature may not be accurate.
A single Analog Thermal Diode located in the center under the Cores is used to measure "CPU" temperature, which is the overall temperature of the entire processor. This is
not Core temperature.
The Analog value is converted to Digital (A to D) by the Super I/O (Input / Output) chip on the motherboard, then is calibrated to look-up tables coded into BIOS for each socket-compatible processor, and is rarely accurate.
Use Core Temp or Real Temp to measure your Core temperatures.
Please download
Prime95 version 26.6 -
http://windows-downloads-center.blogspot.com/2011/04/prime95-266.htm
Please run only Small FFT’s for 10 minutes.
Your Core temperatures will test 10 to 20C lower than later versions of Prime95, such as 28.5.
