What's the nominal voltage for your CPU?

If you don't have fans connected or they are not able to report their
speed, set the limit to 0 to get rid of the alarm. If you have slow
fans, increase the fan clock divider values to 4 or 8 to get the speed
reading, and set the limits to lower values too.

I have no fan and set the min to 0 as you say, alarm has disappeared,

[lm-sensors] vt8231 - epia800

[Roger Lucas]

Hi Gabe,

 

I haven't tried the VT8231 driver with an Epia 800 as I don't have one.  For
my Epia 5000 board, my current sensors.conf is below.

 

The temperature scaling was found by measuring the device heatsink with a
thermal probe whilst monitoring the VT8231 output.  The curve is very
different to anything from VIA or anyone else, but it is accurate for my
Epia 5000 boards (I have 4 of them).

 

The voltage scaling is totally dependent on the external resistors to the
VT8231.  If your board has the same external resistor combinations as mine
then the voltages are the same.  If you have different resistors then you
will have to work out which is which.  Let me know if you feel the need to
go down the same path and I'll give you some pointers..

 

FWIW, I am running the 2.6.14 kernel.

 

Regards,

 

Roger

What's the nominal voltage for your CPU?

I have tried your sensors.conf. I needed to change VCore, mine, in bios, is
1.65V. But temp1 is not displayed when running sensors. However there are 3
files for temp1 in "/sys/devices/platform/i2c-9191/9191-6000". I dn't
understand !

FYI, I have modified my 800 in fanless motherboard (Zalman NB47J). It's why
I want to monitor temperature.

If I don't need a big electronic equipment I'd like ;-)

Which patch? The vt8231 driver is already included in 2.6.16-rc3.

Not sufficient, you'll need version 2.10.0 (just released) for vt8231
support for Linux 2.6.

the patch 1/5 given the february 14th on this ML
I looked at the vt8231.c in my kernel sources and it was not already
applied.

Hi !

It seems good now, with the 2.10.0 sensors :

+12V:     +12.14 V  (min = +11.36 V, max = +12.55 V)
+5V:       +5.11 V  (min =  +4.73 V, max =  +5.23 V)
+2.5V:     +2.48 V  (min =  +2.42 V, max =  +2.57 V)
VCore:     +1.68 V  (min =  +1.56 V, max =  +1.72 V)
NorthBridge Core:
           +3.50 V  (min =  +3.31 V, max =  +3.66 V)
+3.3V:     +3.30 V  (min =  +3.13 V, max =  +3.46 V)
fan1:        0 RPM  (min =    0 RPM, div = 2)
fan2:        0 RPM  (min =    0 RPM, div = 2)
CPU Temp:  +32.5?C  (high =  +266?C, hyst =   -58?C)

thanks ;-)
