To configure the sensor chip for the correct voltage range,
you must set the "vrm" correctly either via /proc, /sys, or sensors.conf.
To be compatible with previous lm_sensors versions, the vrm defaults
to version 8.2. Generally, for recent motherboards, this will not
be correct. Try 9.0 first.
To change the vrm version to 9.0, for example, do the following
after the chip module (in this example, w83781d) is loaded:
(kernel 2.4)
echo 9.0 > /proc/sys/dev/sensors/w83781d-isa-0290/vrm
(kernel 2.6)
(kernel 2.6 up to 2.6.13)
echo 90 > /sys/bus/i2c/devices/0-0290/vrm
(kernel 2.6.14 and later)
echo 90 > /sys/class/hwmon/hwmon0/device/vrm
Alternatively, add a line in /etc/sensors.conf in the w83781d section
(you should put this line BEFORE any line that uses vid in a calculation):
