[lm-sensors] CPU Temp on ECS NFORCE3-A939

[Lou@ParisiHome.net (Lou Parisi)]

I am running CentOS 4 (uname ?r 2.6.9-34.0.1.EL) with an ECS NFORCE3-939 MB
and AMD Athlon64 3000+ processor

 

I am having problems with the CPU temp and core voltage value using
lm-sensors.

 

I first installed lm-sensors using yum (lm_sensors.x86_64  2.8.7-2.40.3).
After install saw these problems so removed the install and installed 2.10
from source.  Got error on make for sysfs/libsysfs.h so installed
sysfsutils-devel using yum (sysfsutils-devel.x86_64  1.2.0-1).  Did make
clean and then installed successfully. 

 

After install ran sensor-detect and detected my chip successfully  The
pertinent output from sensors-detect:

 

------------------ sensors-detect output start
-------------------------------

Probing for `ITE 8712F Super IO Sensors'

  Success... found at address 0x0290

 

To make the sensors modules behave correctly, add these lines to

/etc/modules.conf:

 

#----cut here----

# I2C module options

alias char-major-89 i2c-dev

#----cut here----

 

To load everything that is needed, add this to some /etc/rc* file:

 

#----cut here----

# I2C adapter drivers

modprobe i2c-isa

# I2C chip drivers

modprobe it87

# sleep 2 # optional

/usr/local/bin/sensors -s # recommended

#----cut here----

------------------ sensors-detect output end
-------------------------------

 

Edited modprobe.conf to add:

alias char-major-89 i2c-dev

 

Generated /etc/sysconfig/lm_sensors:

# Generated by sensors-detect on Sat Jun 17 16:02:34 2006

MODULE_0=i2c-isa

MODULE_1=it87

 

Lsmod:

[root at web etc]# lsmod

Module              Size      Used by

it87                   28393  0

i2c_sensor        4161     1 it87

i2c_core            27841   3 it87,i2c_sensor,i2c_isa

 

Had to adjust voltages computations for in5 and in6 from a post I found
regarding a TYAN mb that had the same chip:    

    compute in5 (@ * (1+4.14)) - (4.096*4.14)  ,  (@ + (4.096*4.14)) /
(1+4.14)

    compute in6 (@ * (1+2.14)) - (4.096*2.14)  ,  (@ + (4.096*2.14)) /
(1+2.14)

 

When I run sensors:

[root at web etc]# sensors

it87-isa-0290

Adapter: ISA adapter

CPU VCore: +1.07 V  (min =  +1.28 V, max =  +1.42 V)   ALARM

+1.5V:     +1.47 V  (min =  +1.42 V, max =  +1.57 V)

+3.3V:     +3.31 V  (min =  +3.14 V, max =  +3.47 V)

+5V:       +4.92 V  (min =  +4.76 V, max =  +5.24 V)

+12V:     +11.71 V  (min = +11.39 V, max = +12.61 V)

-12V:     -12.11 V  (min = -12.60 V, max = -11.37 V)

-5V:       -4.80 V  (min =  -5.25 V, max =  -4.75 V)

Stdby:     +5.03 V  (min =  +4.76 V, max =  +5.24 V)

VBat:      +2.94 V

CPU Fan:  3245 RPM  (min = 3013 RPM, div = 8)

Case Fan:  981 RPM  (min =  664 RPM, div = 8)

Temp1:        +4??C  (low  =   +15??C, high =   +40??C)   sensor thermistor

Temp2:       +30??C  (low  =   +15??C, high =   +45??C)   sensor thermistor

 

Everything looks good except the CPU core voltage and CPU temp.  

The bios reads 1.37V for coreV but lm_sensors reads 1.07 consistently.

 

The bios for temps: MB = 31 and CPU = 52.  Both are pretty consistent in the
bios.

The CPU temperature in lm_sensors fluctuates between -5 and 50.  I have
tried using the diode for both temp1 and temp2 and ignoring different
combinations with no success.  If the temperature was consistent I would
feel better like a correction factor was needed but it is all over the
place.  Also the chip designation in sensors.conf is 

chip "it87-*" "it8712-*"

If I have just ?it8712-*? it does not detect the configuration in the
sensors.conf and uses all defaults.

 

Can you help me out at all?  The CPU temp was the main thing I am looking
for.

 

Thanks for any help you can provide.  I have also sent a support request to
ECS but don?t really expect too much help from them.

 

Thank you, Lou Parisi
