Hi Sebastian, FYI, lm78@ is an alias on sensors at .

As far as I remember, thermistors have their nominal resistance known at 25 degrees Celcius, and the temperature is computed using a voltage divisor involving a (non-thermistor) resistor of the same value. So this value of 25 degrees may not be exactly random, it could mean that no thermistor are used and the inputs have been "neutralized" using regular resistors. > The only source with a little more info on this topic I found at: > http://www.livewiredev.com/bbs/showthread.php?s=&postid=13766 > > However, they discuss over there only about voltage readouts.

I found this: http://www.hardwarebg.com/reviews/gigabyte/8pe667ultra/pics/bios_vcore.jpg This probably confirms my original thoughts. The BIOS only shows one temperature (temp3, obviously). I don't think that the two other temperature inputs are wired at all. There's nothing we can do about this. You can try asking Gigabyte for confirmation. > I am sure the sensors work on my mainboard because some time ago I had > Windows on the machine and Gigabyte's EasyTune utility was showing > proper temperatures. Interesting. However, without the source or info from Gigabyte, there's not much we can do. Maybe some extra, board-specific step is required to enable the readings? I can't tell. That's not something we can guess. Either Gigabyte tells you, or you will have to live without the values (the CPU temperature is the most important temperature anyway). > Any help on this matter would be greatly appreciated.

I understand your needs, but we just can't do anything without additional data that only Gigabyte could provide - and this is if there *is* a way to get the readings. Maybe there isn't at all. -- Jean Delvare http://khali.linux-fr.org/
