Hello list, this is my first time posting here, and I come with some
questions about my server motherboard with the hopes that I configure
sensors on it correctly.
While this Soltek board is relatively old (as the company is no longer
in business), I had never used it since the day that I bought it. The
board was recently installed into a server role and I hope to monitor
its health from a distance.
While sensors detects the correct chips installed on the board, the
values are useless.
I'm wondering if anyone can shed light on how to set the values
correctly for this board. Here's some pertinent info:
ITE IT8712F, National LM90 (ISA 290h, SMBus 4Ch)
acpitz-virtual-0
Adapter: Virtual device
temp1: +40.0°C (crit = +75.0°C)
k8temp-pci-00c3
Adapter: PCI adapter
Core0 Temp: +50.0°C
Core1 Temp: +42.0°C
it87-isa-0290
This would be an IT8705F chip, not IT8712F as you wrote above.
OK, I was going off of a forum post (one of a few about this specific
motherboard, as the site is now unavailable, and finding information is
scarce)
Adapter: ISA adapter
in0: +1.31 V (min = +0.00 V, max = +4.08 V)
in1: +2.54 V (min = +0.00 V, max = +4.08 V)
in2: +3.28 V (min = +0.00 V, max = +4.08 V)
in3: +2.90 V (min = +0.00 V, max = +4.08 V)
in4: +2.91 V (min = +0.00 V, max = +4.08 V)
in5: +0.96 V (min = +0.00 V, max = +4.08 V)
in6: +1.12 V (min = +0.00 V, max = +4.08 V)
in7: +2.94 V (min = +0.00 V, max = +4.08 V)
Vbat: +3.26 V
fan1: 11250 RPM (min = 3245 RPM)
fan2: 4963 RPM (min = 0 RPM)
temp1: +26.0°C (low = -1.0°C, high = +127.0°C) sensor =
thermistor
temp2: -86.0°C (low = -1.0°C, high = +127.0°C) sensor =
thermal diode
temp3: +14.0°C (low = -1.0°C, high = +127.0°C) sensor =
thermistor
lm90-i2c-0-4c
Adapter: SMBus Via Pro adapter at 5000
temp1: +38.0°C (low = +0.0°C, high = +70.0°C)
(crit = +85.0°C, hyst = +75.0°C)
temp2: +63.1°C (low = +0.0°C, high = +70.0°C)
(crit = +85.0°C, hyst = +75.0°C)
If I can provide more information, let me know.
I have been playing with the values and I feel that I have made some
progress. Identifying the sensors is difficult as they all seem to show
different patterns.
Under it87, temp1 is almost constant, it hovers around 26C, currently
it's at 24C and I've seen it go as high as 27C. Using stress (with all
the different hogs), the temperature does climb, but not right away and
this leads me to believe that this is indeed a sensor and it monitors
the ambient/case temperature.
temp2 is a negative value and stays constant within a 3 degree range if
set to a thermal diode, if set to thermistor it seems to stay constant
at negative 55. This is all throughout multiple stress runs, both
memory, i/o, disk and CPU. I'm assuming that this sensor is not connected.
temp3 swings wildly from -110 to about 108 degrees, and all over in
between. I've tried setting it as a thermistor or diode, and it still
goes all over the place. I'm wondering what I can do with this sensor
as it's not really reading correctly. It must be sensing something, as
it does produce values all over the range, I'm just stumped as to what
kind of compute function I would need to use to make this thing make any
kind of sense.
If it jumps all over the place no matter the setting, then you can
safely conclude that it is left floating and should be disabled/ignored.
I visited your site and found a few examples that said the manufacturer
left the sensor floating. I was unaware as to what that meant exactly.
Thanks for letting me know. I have now disabled all three temperature
readings.
I will further ask questions about the rest of the detected chips as I
get to them, though I'd appreciate any thoughts on the above temperature
sensors.
Given that the board vendor used a dedicated LM90 temperature
monitoring chip to track the CPU temperature, I wouldn't be surprised
if most or all of the IT8705F temperatures inputs were left unused. The
I was getting that feeling through my many attempts at computing the values.
it87 driver forcibly enables temperature monitoring channels if they
are found all disabled when the driver is loaded. It probably shouldn't
do that, especially given that each channel can be configured in two
different modes (thermistor and thermal diode) and the driver has no
way to know which mode would be correct. Incidentally, your modes
configuration for temp1, temp2 and temp3 matches the arbitrary default
set by the it87 driver, so it is possible that all sensors were indeed
disabled originally.
OK, understood.
I will fix the it87 driver later today to no longer arbitrarily enable
temperature sensors. This should clear some confusion as least on some
boards.
What temperatures are reported by the BIOS on this machine? This would
be a valuable hint.
The BIOS reports that CPU temp is at 60C and that SYS temp is at 20C.
I've run across a few posts about the CPU temperature reported via the
windows utility and the bios reports as being off. I know the
manufacturer released a BIOS revision after mine, though unfortunately
it's quite buggy and most of the people who ran/run this board
downgraded back to the version I'm running.
I've guessed at the second temperature that the LM90 reports and used a
calculate formula to reduce the reading by 10% as 60C is very high for
an undervolted Opteron 165.
