Support for ROG STRIX B650E-F GAMING WIFI

[psibi]

I tried to add support for it using the existing code, but wasn't successful. Relevant branch: https://github.com/psibi/asus-ec-sensors/tree/b650e

When I try to run sensors command with my branch, this is what I see:

asusec-isa-0000

This is my DSDT dump: dsdt.tar.gz

Let me know if there is anything else I can add that will help.

Hey!

Usually the ASUS boards provide sensors readings via EC when the number of sensors do not fit in the Super I/O registers. With this board I see only the T_Sensor, and it should fit. The DSDT contains no mention of the EC device either.

Thanks!

Is there driver for T_Sensor that I can ? Right now all I see is this via sensors:

amdgpu-pci-0b00
Adapter: PCI adapter
vddgfx:        1.28 V  
vddnb:         1.01 V  
edge:         +40.0°C  
PPT:          42.23 W  

nvme-pci-0a00
Adapter: PCI adapter
Composite:    +33.9°C  (low  =  -5.2°C, high = +89.8°C)
                       (crit = +93.8°C)

k10temp-pci-00c3
Adapter: PCI adapter
Tctl:         +44.1°C  
Tccd1:        +38.5°C  
Tccd2:        +35.0°C

You need to find out the model of the Super I/O chip this board is using. The sensors-detect utility might help.

Cool, thanks. Closing this issue then.

If you have and access to Windows, HWINFO shows chip names.

I saw that the upstream linux supports this motherboard using NCT6775 driver: https://github.com/torvalds/linux/blob/cc8ed4d0a8486c7472cd72ec3c19957e509dc68c/drivers/hwmon/nct6775-platform.c#L1385

I was able to load it via modproble:

❯ sudo modprobe -v nct6775
[sudo: authenticate] Password:
insmod /run/booted-system/kernel-modules/lib/modules/6.6.32/kernel/drivers/hwmon/hwmon-vid.ko.xz
insmod /run/booted-system/kernel-modules/lib/modules/6.6.32/kernel/drivers/hwmon/nct6775-core.ko.xz
insmod /run/booted-system/kernel-modules/lib/modules/6.6.32/kernel/drivers/hwmon/nct6775.ko.xz

And then see sensors CLI report additional information like fan speed, various temperatures etc.
