Linux 6.3 Supports Sensor Monitoring For Many ASUS B650/B660/X670 Motherboards

[Melcar]

Any day now then .

Joking aside, I do understand that in Linux you need to put some work in to get stuff in return. I'm not complaining, just saying that I don't care anymore, since it's almost futile. Last time I bothered was with a X370 board. Fun experience to be honest, but not something I want to repeat every time I upgrade my motherboard. Yeah, the sensors thing is a complete mess and pretty much guesswork, and it will continue to be that way.

Some boards could require addition patch apply for support newer version of chip https://patchwork.kernel.org/[email protected]/

In such case dmesg should contain some message about wrong chipid.

what board do you have?

Thanks,
I have PRIME B550-PLUS and PRIME B350-PLUS boards.

PRIME B550-PLUS - should be supported v6.0+ kernels, as I remember, may be just missed by some reason or just some unexpected error.

PRIME B350-PLUS - is unsupported by upstream code, maybe it can be supported by some workaround.

You can attach exact error to https://bugzilla.kernel.org/show_bug.cgi?id=204807, if it's not simple case like outdated kernel version.

Exact error of what? I don't have any error. I just don't see any temps from motherboard.

5.10 kernel does not have support for proxy access to nct6775 sensors on Asus boards.

B350 boards are not supported for now, you can try to build with patch from 204807 but no guarantees for now.

B550 boards are supported by latest kernel. 6.1 with backports also should be.

Could you please try to run 'sudo modprobe nct6775' and look to outputs of 'sudo dmesg' or run sensors-detect from lm_sensors and than look for what do you have in dmesg and sensors output?

Patch from https://bugzilla.kernel.org/show_bug.cgi?id=204807#c301 could support B350 board. Patch has several boards with comment "// use custom port definition", such boards are supported in theory, but need to check with real boards and share dmesg messages related to nct6775 module - after such check support of such board could be sent to upstream.

Fantastic, it worked!

How can I enable this module permanently, so it loads on every boot?

[piorunz]

B350 machine is production-grade homeserver, so I won't be patching that, unfortunately. But once new Debian is out, I will be on 6.1 kernel and I can try things.

Sensors-detect as last question asks about add detected sensors to autoload.

Also Arch Linux documentation has instructions for do it manually https://wiki.archlinux.org/title/Kernel_module

Excellent, thanks! That worked. Sensors-detect has added appropriate line to /etc/modules file.

Thank you! Could you please make one more check on b350 with a currently installed kernel, version doesn't matter, run modprobe nct6775 and check what is the error in dmesg? It should say that sensor is detected, but have conflict with acpi resources.
it will be positive case as kernel just need add b350 boards to the accepted boards list to use Asus wmi methods.

Otherwise support b350 boards will more complicated story with search correct methods to have access to sensors or use it87 or some other sensors module with additional patches.
