Worrying output from lm87 sensors! (Examined/Solved - lm_sensors 2.5.5, Linux 2.4.0 SMP)

[contact]

This is what the sensors give me for the lm87 devices on my Supermicro PIIIDME.

This board has 2 733 MHz PIII (Coppermine) CPUs:

lm87-i2c-0-2e

Adapter: SMBus I801 adapter at efa0

Algorithm: Non-I2C SMBus adapter

2.5V: +0.00 V (min = +1.49 V, max = +1.64 V) ALARM

Vccp1: +0.60 V (min = +0.94 V, max = +1.05 V) ALARM

3.3V: +3.21 V (min = +3.12 V, max = +3.47 V)

12V: +11.93 V (min = +11.37 V, max = +12.62 V)

Vccp2: +0.00 V (min = +1.49 V, max = +1.64 V) ALARM

fan1: 4856 RPM (min = 3000 RPM, div = 2)

fan2: 4753 RPM (min = 3000 RPM, div = 2)

This is obviously very worrying! I have checked in the BIOS and found the

following:

CPU1 50 degrees

CPU2 54 degrees

IN0 +1.57

IN1 +1.57

IN2 +3.29

IN3 +4.97

IN4 +11.91

CPU Fan1 4891

CPU Fan2 4753

Chassis Fan1 0

Chassis Fan2 0

So I have (apparently) no chassis fans and the fan on CPU2 runs slower than the

one of CPU1, which would explain why CPU2 is slightly warmer.

--- The driver assumes certain scaling factors for the 2.5V and Vccp1 inputs.

It looks like yours is quite different.

It looks like 2.5V and Vccp1 on the first chip are your two core voltages.

Adjust the 2.5V by multiplying by .67 and the Vccp1 by multiplying

by 2.7 in sensors.conf.

I think we will probably make the driver a little more general

in the future by moving the calculations from the driver to

sensors.conf.

If you need more assistance you can follow up by sending mail

to sensors@… and reference your ticket #.
