Uguru Accuracy

[shackahn]

I am running the Uguru software and its recording my CPU temp as 35 C yet using a rpogr4am called core temp as recommended in the core duo overclocking guide it records both cores at 42 C which is likely to be more accurate?

Basically coretemp is the most accurate as it take the temps from core1 and core 2, where as uGuru takes the temp from the cpu, as in everest it displays the same temp for the cpu in uGuru and the same temp for the cores as coretemp.

thanks for the prompt reply the information is much appreciated

This whole issue of "accuracy" is something of a red herring. As Daza says, CoreTemp is reporting the readings from the Digital Thermal Sensors, which are placed in the hottest part of each core. The very fact that the DTS' are fully digital also eliminates some of the potential for conversion errors which are present in the more established methods of measuring in-system temperatures.

As such, if you believe Intel's blurb, the DTS is the most accurate way of ascertaining the temperature of a Core 2 CPU. However, that doesn't mean that the values reported by uGuru are inaccurate. uGuru takes its readings from a sensor in a different physical location. As such, it could be argued that it's just as accurate as the DTS, it's just measuring the temperature in a different place.

As the Digital Thermal Sensors are physically located right in the heart of the CPU core, these readings are the most useful indication of the actual processor working temperature.
