Summary0000738: On AMD dual core setups, only the second core temperature is detected
DescriptionOn AMD Dual Core systems, Speedfan detects only one DTS instead of two, thus only the temperature readout from the second core is shown. The DTS first core is ignored.

This could be a significant problem, because the second core has been frequently reported to run cooler than the first one.

Found an earlier report (August '06), the same issue was fixed, so this could be a regression.

FWIW, 4.32 Final still broken.

Three months are passed, and you don't give a ***.

Thank you for you outstanding support work.

Alfredo: please disregard the earlier poster's rudeness. Thanks for a great piece of software.

I have the same behaviour running Speedfan 4.37 with my Athlon X2 4200+ (only the second core temp is reported).

@johnmwilson
Hello,
issue 0000611 was of a different kind. It was about multi-processor systems. SpeedFan doesn't currently show the temperature of the second core of AMD CPUs because it requires writing to some registers where other tools will write rather often and I don't know of a semaphore dedicated to avoid collisions. Anyway: I will have a look at my source code and will consider adding this feature.

Thanks for the prompt response.
If you get chance to add this then that's great -- it's obviously only of minor importance.

Just to note in case it's any help: lm_sensors under linux <www.lm-sensors.org> reads both core temps; don't know how they deal with the collisions issue.
