 |
|
Man, lm-sensors is driving me crazy. I have an Asus k8n (not the delux) motherboard. In the bios, I have hardware monitors that display fan speeds and cpu temperatures. I'm trying to get lm-sensors working. Have built in all the sensors as modules in a 2.6.10-gentoo-r7 kernel, and run a sensors-detect. It always tells me to modprobe the i2c-isa adapter, and the it87 chip driver. I would think that I should use the nforce2 adapter, since I have an nforce3 chipset. Maybe the sensors run completely off of something else though. So, after I run sensors-detect, create the /etc/conf.d/lm_sensors file, uptade-modules, and modprobe the i2c-isa and it87, sensors gives me this output. | /usr/bin/sensors wrote: |
it8712-isa-0d00
Adapter: ISA adapter
|
Just blank. Is there any way to fix this, or to find out the correct modules to use. I haven't found anything on google with this motherboard. Everyone just says to run sensors detect, but its obviously not working correctly. Help me shed some light on this.

Ok, i seemed to have fixed it by upgrading to the latest lm-sensors. same modules, output now shows | sensors wrote: |

should I be worried about all the alarms?

| no alarms occur since the value is greater than the min/max values - these, as you can see, generally dont make any sense and are wrong. |

Does someone have a working /etc/sensors.conf? I tried to adjust it myself, but I only can play with the values inside instead of really knowing what I do 
Thanks

If your using my board, around line 1403
| Code: |
chip "it87-*" "it8712-*"
# The values below have been tested on Asus CUSI, CUM motherboards.
# Voltage monitors as advised in the It8705 data sheet

label in7 "Stdby"
label in8 "VBat"
# vid is not monitored by IT8705F
# comment out if you have IT8712

# Incubus Saturnus reports that the IT87 chip on Asus A7V8X-X seems
# to report the VCORE voltage approximately 0.05V higher than the board's
# BIOS does. Although it doesn't make much sense physically, uncommenting
# the next line should bring the readings in line with the BIOS' ones in
# this case.
# compute in0 -0.05+@ , @+0.05
# If 3.3V reads 2X too high (Soyo Dragon and Asus A7V8X-X, for example),

# the lm78. The chip uses two external resistor for scaling but one is
# tied to a positive reference voltage. See ITE8705/12 datasheet (SIS950
# data sheet is wrong)
# Vs = (1 + Rin/Rf) * Vin - (Rin/Rf) * Vref.
# Vref = 4.096 volts, Vin is voltage measured, Vs is actual voltage.
# The next two are negative voltages (-12 and -5).
# The following formulas must be used. Unfortunately the datasheet
# does not give recommendations for Rin, Rf, but we can back into
# them based on a nominal +2V input to the chip, together with a 4.096V Vref.
# Formula:
# actual V = (Vmeasured * (1 + Rin/Rf)) - (Vref * (Rin/Rf))
# For -12V input use Rin/Rf = 6.68
# For -5V input use Rin/Rf = 3.33
# Then you can convert the forumula to a standard form like:

I didn't change much except swap the "CPU Temp" and "M/B Temp" labels, they seem to be inverted for this board, and I commented the line out above where it says to comment out if your Voltages for 3.3V are doubled. The temps seem to be off though, booting up in the bios says my cpu is idle at 40 - 44C, but lm-sensors says its idle at 36C. If anyone knows the formula for fixing that, please post

Thanks. In the meantime I played around a bit and I got a (final) working config, which only shows these sensors which really exist.
it8712-isa-0d00
Adapter: ISA adapter
VCore 1: +1.49 V (min = +1.23 V, max = +1.57 V)
+3.3V: +3.28 V (min = +3.14 V, max = +3.47 V) ALARM
+5V: +4.95 V (min = +4.76 V, max = +5.24 V)
+12V: +11.84 V (min = +11.39 V, max = +12.61 V)
fan1: 0 RPM (min = 0 RPM, div = 2)
CPU Temp: +43°C (low = +15°C, high = +45°C) sensor = thermistor
M/B Temp: +39°C (low = +15°C, high = +40°C) sensor = thermistor
The fan does not recognize the low spped, if the cpu is not hot enough
