Re: high value for CPUTIN

Guenter,

On various ASUS boards with NCT6776F, it appears that CPUTIN is not really
connected to anything and floats, or that it is connected to some non-standard
temperature measurement device. As a result, the temperature reported on CPUTIN
will not reflect a usable value. It often reports unreasonably high
temperatures, and in some cases the reported temperature declines if the actual
temperature increases (similar to the raw PECI temperature value - see PECI
specification for details). CPUTIN should therefore be be ignored on ASUS
boards. The CPU temperature on ASUS boards is reported from PECI 0.

Thank you very much for this information. Now I wonder about the relation
between the BIOS CPU temperature and the value reported by PECI 0. That is, do
they obtain their values from the same device?

I have checked now and while on the one hand the BIOS report a CPU temperature
of 32C and a MB temperature of 29C, which sounds reasonable, on the other hand
PECI 0 reports 21C, even below room temperature! Note that other values like
AUXTIN and Core 0 to 3 look more compatible, in the range of 30 to 31C. So, it
looks like there is an error of over 10C in the value reported by PECI 0. Is
it the expected behavior?

Alejandro
