Retail Q9650 Overclocking Thread

[vws]

Folks, don't bother with any core temp readings below 50°C - they are simply not accurate. Quote from this recently released Intel datasheet regarding the thermal sensor issue:

The digital thermal sensor (DTS) accuracy is in the order of -5°C +10°C around 90°C ; it deteriorates to ±10°C at 50°C. The DTS temperature reading saturates at some temperature below 50°C. Any DTS reading below 50°C should be considered to indicate only a temperature below 50°C and not a specific temperature. External thermal sensor with “BJT” model is required to read thermal diode temperature.

From my own tests, I found it better be corrected to "60°C" to be closer to reality. Anything below 60°C in my experience doesn't make much sense at all.

Also here's an article at Tom's HW that's worth reading. It talks about how to set the Tj Max value accurately for your CPU.
