Issues with sensor reporting on IT8625E #32

Open jrfbal opened 3 months ago

jrfbal commented 3 months ago

Hello, I have a Biostar B760M-SILVER motherboard and it is running Unraid. According to sensors-detect, it has a Chip `ITE IT8625E Super IO Sensors'

I've installed the ITE IT87 Driver kit and it triggers weird behaviours:

The motherboard temperature sensor occasionally starts sending wrong data (-30C)
The fans sensor show the speed correctly, but sometimes send impossible values (70000rpm)
The CPU fan sometimes stop spinning and being managed by the motherboard
Occasional system lock-ups

This wrong reports do not show on the Bios or if the driver is not installed.

Currently due to the instability I have removed the drivers, but I can reinstall them for troubleshooting reasons.

Thank you

@jrfbal first off, can you send me what is reported by cat /sys/class/dmi/id/board_vendor and cat /sys/class/dmi/id/board_name

Then run sensors-detect and see what it reports as the chip IDs (note this may say they are not supported as it doesn't know all the chips available in the IT87 module).

Hello, Sure: root@Unraid:~# cat /sys/class/dmi/id/board_vendor BIOSTAR Group root@Unraid:~# cat /sys/class/dmi/id/board_name B760M-SILVER

sensors-detect returns only the following sensors:

Intel digital thermal sensor... Success! (driver 'coretemp') Found 'ITE IT8625E Super IO Sensors' Success! (address 0xa20, driver 'to-be-written')

At the moment I don't have the drivers installed due to the instability I've reported. It is currently with 3 days of uptime without any crashing or wrong temperature readings.

Thank you

Hello, @frankcrawford, Is there anything else you need on my end? Thank you

@jrfbal sorry, been busy with some other things. Much of the issue is that most of the development is done on Gigabyte boards, so it isn't clear exactly how BIOSTAR Group have wired it up.

That will take some digging, and right now I don't have a lot of time to do it.

If you can find a bit more about BIOSTAR and any low-level documentation they may have for their boards it would help.

Thanks Frank
