|
||||
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):
