D945GSEJT and sensors

Community Manager

I have a small server based on a D945GSEJT board which is running Ubuntu 10.04LTS. I would like to be able to monitor the server hardware. To do that I have loaded successfully the coretemp and w83627 kernel modules and indeed the sensors command produces an output. Some of the output is easy to interpret (the system has no fans so ignore that and it does not have a temp3 sensor so ignore that too). What I am a looking for is the interpretation of the voltages that come out of the default sensor command:



Adapter: ISA adapter


Vcore: +0.86 V (min = +0.00 V, max = +1.74 V)


in1: +1.58 V (min = +0.28 V, max = +1.65 V)


AVCC: +3.39 V (min = +2.98 V, max = +3.63 V)


VCC: +3.39 V (min = +2.98 V, max = +3.63 V)


in4: +1.89 V (min = +1.18 V, max = +0.65 V) ALARM


in5: +1.22 V (min = +0.26 V, max = +1.13 V) ALARM


in6: +1.59 V (min = +0.43 V, max = +0.60 V) ALARM


3VSB: +3.42 V (min = +2.98 V, max = +3.63 V)


Vbat: +3.33 V (min = +2.70 V, max = +3.30 V) ALARM


fan1: 0 RPM (min = 10546 RPM, div = 128) ALARM


fan2: 0 RPM (min = 10546 RPM, div = 128) ALARM


fan3: 0 RPM (min = 10546 RPM, div = 128) ALARM


fan4: 0 RPM (min = 10546 RPM, div = 128) ALARM


fan5: 0 RPM (min = 10546 RPM, div = 128) ALARM


temp1: +44.0°C (high = -58.0°C, hyst = +64.0°C) sensor = diode


temp2: +58.5°C (high = +80.0°C, hyst = +75.0°C) sensor = diode


temp3: +127.0°C (high = +80.0°C, hyst = +75.0°C) ALARM sensor = thermistor


cpu0_vid: +2.050 V

I have looked all over for a description of the voltages using the W83627 chip on this board but alas every motherboard manufacturer can and does his own thing. Therefore configs for Supermicro boards don't seem to make much sense for the intel board and vice versa. Also, there is no descrption in the board's manual of the different voltages measurements. Nor have I been able to find anything on the intel web sites. Anyone have any idea of what in especially in1, in4, in5 and in6 are? For instance, I would expect at least one of them to be the 12V input.

Here's the information for D945GSEJT:

Input Voltage Multiplier Necessary


VIN1 +5V 3.2

VIN2 +12V 6.6

VIN3 +3.3V 2.8

VIN4 +5V Standby 3.2

Problem has been solved. I have a config file for the sensors now that make sense.

Many Thanks

Any chance you could share the config file?

Many thanks

Hi, it would be really helpful if you can share the config file.

Thanks in advance,
