Odd results using lm-sensors

I installed this, and the sensors or sensors -f command give me weird results.

The CPU temp seems fine, (AMD FX-4350), as does the AMD Radeon R7-250X in a PCI slot.

In the ISA section I get goofy stuff, like

in4 +0.30V min=+1.52V max=+0.90 ALARM

Why is the minimum > the maximum, and if the minimum can't be less than 0.90, why does my PC work fine when the value is 0.30

mobo is ASUS M5A97 R2.0

Any help much appreciated,

TIA

I guess sensor data is misinterpreted. And it seems that min. max data is not good too. I've experienced something like that in the past.
I would ask upstream.

Thanks filip,

Good idea, I will do as you suggest. It does seem like that lm-sensors is misunderstanding the data. Could be ASUS using a non standard reporting system, could be the software itself.

Or could be that the sensor is simply broken or presents bogus values. Maybe you can crosscheck the sensor values against what you can see in BIOS / UEFI under system health or system monitoring.

I had to calibrate lm_sensors to work right with my ASUS Sabertooth 990FX R2 mobo because the sensors3.conf file did not contain valid configuration for that board.

Here are my settings. If your sensors chip is one of these, you might try these settings and tweak them as required.
Code: Select all
chip "it87-*" "it8712-*" "it8716-*" "it8718-*" "it8720-*" "it8721-*"

    label in0 "+12V"
    label in1 "+5V"
    label in2 "VCore"
    ignore in4
    ignore in5
    label in8 "Vbat"
    label temp1 "CPU Temp"
    label temp2 "M/B Temp"

    compute in0 @*(515/120), @/(515/120)
    compute in1 @*(215/120), @/(215/120)
    set in0_min 12.0 * 0.9
    set in0_max 12.0 * 1.1
    set in1_min 5.0 * 0.9
    set in1_max 5.0 * 1.1
    set in2_min 0.7
    set in2_max 1.7
    set in3_min 3.3 * 0.90
    set in3_max 3.3 * 1.1

    set temp1_min 2.0
    set temp1_max 65.0
    set temp2_min 2.0
    set temp2_max 68.0
    ignore temp3
    ignore fan3

As a follow-up, I just went back and checked (from my installation history), my records show that the entry I created actually adds support for the lm8721 chip. Maybe I should forward the information upstream...
