[lm-sensors] w83793 on X7DWA-N

[Andrew Lyon]

Hi,

I have lm_sensors 3.0.2 on a supermicro X7DWA-N with kernel 2.6.25.15,
I am trying to work out how the lm_sensors voltage readings map to the
sensors shown in the bios and described in the motherboard manual, the
manual states:

Onboard Voltage Monitors for the CPU Cores, Chipset Voltage, Memory
Voltage, +1.8V, +3.3V, +5V, +12V, -12V, +3.3V Standby, +5V Standby and
Vbat

sensors output:

VCoreA:      +1.20 V  (min =  +0.92 V, max =  +1.49 V)   = CPU Cores
VCoreB:      +1.20 V  (min =  +0.92 V, max =  +1.49 V)   = CPU Cores
Vtt:         +1.08 V  (min =  +0.99 V, max =  +1.33 V)   = ?
in3:         +0.51 V  (min =  +0.38 V, max =  +0.69 V)   = ?
in4:         +1.46 V  (min =  +1.34 V, max =  +1.65 V)   = ?
+3.3V:       +3.28 V  (min =  +2.96 V, max =  +3.63 V)   +3.3V?
+12V:       +11.81 V  (min = +10.75 V, max = +13.25 V)   +12
+5V:         +5.02 V  (min =  +4.64 V, max =  +5.65 V)   +5
5VSB:        +5.05 V  (min =  +4.64 V, max =  +5.65 V)   +5V Standby
VBAT:        +3.18 V  (min =  +2.99 V, max =  +3.66 V)   Vbat

Can anybody explain the differences?

Andy

Don't blindly trust the manual. Better check what the BIOS displays.

in3 is -12V but you need the proper scaling factor. in4 is +1.5V
(typically what AGP 4x uses). I confirm that +3.3V (in5) is +3.3V ;)
The rest is correct. I am not sure if in2 (Vtt above) is really used, I
guess not.
