k8n-vm sensors

[-]

I just bought this board for my small server combined with an AMD Semp
2600+

When I go to BIOS, the CPU temp and Case temp are normal, 29 and 30
celcius. But when I try a temp viewer in windows, whatever I used,
Asus Probe II included on the CD with the board, motherboard monitor
with another board with same family sensor chip chosen, SpeedFan which
detect the sensor chip (Winbond W83627EHF), I always get 2 anormal
reading, 112 and 113 celcius for 2 of the 3 temp sensors. The third is
29. Also, I set QFan to on, but the fan don't seems to slow down.

Anyone with this board get good temp reading from Asus Probe II?

A monitor channel can be in diode mode or thermistor mode.
On PDF page 71, there is an option to select diode or thermistor
mode. It could be that the wrong mode is being used by the
software.

Maybe this is a BIOS issue ? I don't really know how the operating
mode of the Winbond chip is supposed to be communicated to
monitoring programs (something in DMI/ESCD ?). Maybe Speedfan
is just supposed to read the registers and not mess around with
the setup of the W83627EHF ?

PDF page 30 of the above doc, implies that a lookup table is
used whether a temp monitoring channel is in diode or thermistor
mode. The beta of the thermistor is specified, as is the resistor
to be used with the thermistor, implying the "temperature measuring
machine" uses different fixed lookup tables for the two modes.
Selecting the wrong (diode versus thermistor) mode will result
in the output register getting wrong values from the lookup table.

The author of Speedfan might understand how the configuration of
the W83627EHF is declared, for use by monitor programs. Perhaps
he can explain why it doesn't work right.

Thanks for your reply. The most worrying part is that even Asus Probe
II don't work. For third party monitor with no "direct" support for my
motherboard I can imagine some bugs, but Asus Probe II, bundled with
THIS motherboard, it's strange. I still wait for an answer from
another user using this board to tell me if he's getting normal
reading from Asus Probe II.

Have you downloaded the latest Asus Probe II ?

If you look in this FTP directory...

ftp://ftp.asus.com.tw/pub/ASUS/misc/utils

the latest ProbeII is Dec 29, 2005. Uninstall the one you
are currently using, and try this one instead. (8,411KB)

I flashed my BIOS and updated my chipset drivers to the latest and the
problem is solved. Every monitor show the right temp now. Thank you
for your help.

I guess Asus already figured out their mistake
