# NCT6687D Kernel module
|
|
|
|
This kernel module permit to recognize the chipset Nuvoton NCT6687-R in lm-sensors package.
|
|
This sensor is present on some B550 motherboard such as MSI or ASUS.
|
|
|
|
The implementation is minimalist and was done by reverse coding of Windows 10 source code from [LibreHardwareMonitor](https://github.com/LibreHardwareMonitor/LibreHardwareMonitor)

## Load(prob) Sensors on boot
|
|
|
|
To make it loaded after system boots
|
|
|
|
Just add nct6687 into /etc/modules
|
|
|
|
`sudo sh -c 'echo "nct6687" >> /etc/modules'`
|
|
|
|
### Arch-Linux with systemd
|
|
|
|
`sudo sh -c 'echo "nct6687" >> /etc/modules-load.d/nct6687.conf'`
|
|
|
|
<br>
|

|
## Tested
|
|
|
|
This module was tested on Ubuntu 20.04 with all kernel availble on motherboard [MAG-B550-TOMAHAWK](https://www.msi.com//Motherboard/MAG-B550-TOMAHAWK) running an [AMD 3900X/AMD 5900X](https://www.amd.com/en/products/cpu/amd-ryzen-9-3900x)
|
|
|
|
<br>
|
|
|
|
## Other motherboard supported
|
|
- Many people have reported compatibility with MB having Intel H410M & H510M chipset from some manufacturer. See [issue](https://github.com/Fred78290/nct6687d/issues) report.
|
|
<br>
|
|
|
|
## CHANGELOG
|
|
|
|
- Add support for MSI B460M Bazooka having NCT6687 with another device ID
|
|
- Add support to use generic voltage input without multiplier, allows sensors custom conf
|
|
<br>
|
|
|
|
## VOLTAGE MANUAL CONFIGURATION
|
|
|
|
Some people report that voltage are wrong. The reason is with some motherboard, voltage sensors are not connected on the same nct6687 register.
|
|
|
|
As example the **VCore** sensor is connected on the **5th** register for AMD but is connected on the **3rd** register for INTEL.
|
|
<br>
|
|
Also the **DIMM** sensor is connected on the **4th** register for AMD but connected to **5th** register for INTEL.
|
|
|
|
To allow customize voltage configuration you must add **manual=1** parameter passed to the module at load
|
|
|
|
`sudo sh -c 'echo "nct6687 manual=1" >> /etc/modules'`
|
|
|
|
And use a sensors conf like this **/etc/sensors.d/B460M-7C83.conf**
|
|
|
|
```
