Partially works with ASRock B650E PG-ITX

[J-Pai]

Thanks for implementing this module! Tested with Ubuntu 22.04 LTS.

Just wanted to leave a note for those who may have this motherboard and want to get Sensor data on Linux.

Actually. I take that back.

Needed to run some diagnostics to make sure CPU Soc voltage was within range.

It looks like for this particular motherboard (ASRock B650E PG-ITX), the voltages are not reported through the driver correctly.

[hfc2x]

I think it partially works because AFAIK, AsRock boards use a different Nuvoton sensor model. I'm not sure about your particular board, but I believe AsRock boards tend to use NCT6796D instead.

[Fred78290]

@hfc2x Did you test with the force flag?

[hfc2x]

Oh, I'm sorry but I don't actually own an AsRock board. I was simply clarifying for the OP.

I have an MSI board, and this kernel module works perfectly for me :)

[J-Pai]

@hfc2x Did you test with the force flag?

What do you mean by the force flag? I might be able to try that out.

[Fred78290]

What do you mean by the force flag? I might be able to try that out.

@J-Pai

sudo sh -c 'echo "nct6687 force=1" >> /etc/modules'

The flag allow to force module to be installed

[J-Pai]

Been a while. Finally got the chance to try this out.

So it looks like the module is being loaded, so doesn't look like force=1 is entirely necessary. It's just like not every setting is mapped correctly.

Looks like I may need to attempt the Manual voltage configuration.

The Voltage settings are still missing.

[J-Pai]

And just some more pieces of information.

@hfc2x is probably right where the device is not entirely supported by the driver.

My device reports back as a nct6686 (not nct6687d).

Kudos to the project. However I had much better luck with my B650E PG-ITX using nct6686 with these settings:

The only outputs I ain't confident about are "CPU Input" voltage and "GPU" temperature, everything else matches with what's set and reported by BIOS. And please disregard the FANs showing 0, sensors do work, it is just that I'm running 100% fan-less system right now.

[J-Pai]

Thanks for the mappings.

I guess my other issue is almost all the sensor inputs are also reporting zero. So even if I remap some of these inputs the outputs are still effectively all zeroes.

Not sure how you were able to get values out of your chipset. To be clear, I haven't updated my BIOS since the first day. Not sure if that might also have something to do with it.
