Ryzen 2600 / MSi B450M Gaming Plus Monitoring/Sensors and Fans

Hello Peeps,

I was just wondering if there's a way to get Ryzen voltages and system fan monitoring and voltage monitoring enabled, im using the Freon sensors extensions / gnome.

Tempuratures work, i can see tcl temps and all that, i just cant get system fans and system voltages

I have tried the it87 method, which im not sure if that works these days, installing the module of AUR and modprobing it with no luck, it just says no such device.

Motherboard: MSi B450M Gaming Plus
CPU: Ryzen 2600

Currently, no.

Hello Team,

Basically i am trying to get better sensor readings for my Ryzen 2600, im using the MSi B450M Gaming Plus motherboard.

I did some research and found that all AMD Boards either use nct6775 or it87 appearently, so i installed the it87 dkms git package and the nct git package and none seem to work

What i find interesting, is that their is a program called CPU-X, similar to cpu-z, which reads everything perfectly fine, my processor, speeds, motherboard, bios version, all of it accept the RAM Manufacturer and fan speeds on my system fans.

So Something must be able to read the motherboard sensors.

i rebooted, tried sensors-detect and got no results besides temperature for K10.

https://aur.archlinux.org/packages/it87-dkms-git/
https://aur.archlinux.org/packages/nct6775-dkms-git/

I tried to modprobe both and it says fatal error its not in /lib/modules.

I am not sure if they are running or if theirs a fault.

Heres the output of sensors detect, in-case it helps

This program will help you determine which kernel modules you need
to load to use lm_sensors most effectively. It is generally safe
and recommended to accept the default answers to all questions,
unless you know what you're doing.

Some south bridges, CPUs or memory controllers contain embedded sensors.
Do you want to scan for them? This is totally safe. (YES/no): y

Some Super I/O chips contain embedded sensors. We have to write to
standard I/O ports to probe them. This is usually safe.

Some systems (mainly servers) implement IPMI, a set of common interfaces
through which system health data may be retrieved, amongst other things.
We first try to get the information from SMBIOS. If we don't find it
there, we have to read from arbitrary I/O ports to probe for such
interfaces. This is normally safe. Do you want to scan for IPMI
interfaces? (YES/no): y

Some hardware monitoring chips are accessible through the ISA I/O ports.
We have to write to arbitrary I/O ports to probe them. This is usually
safe though. Yes, you do have ISA I/O ports even if you do not have any
ISA slots! Do you want to scan the ISA I/O ports? (YES/no): y

Lastly, we can probe the I2C/SMBus adapters for connected hardware
monitoring devices. This is the most risky part, and while it works
reasonably well on most systems, it has been reported to cause trouble
on some systems.

Now follows a summary of the probes I have just done.
Just press ENTER to continue: 

Driver `k10temp' (autoloaded):
  * Chip `AMD Family 17h thermal sensors' (confidence: 9)

No modules to load, skipping modules configuration.

Unloading cpuid... OK

Do this:

sudo modprobe nct6775

Shouldn't need DKMS, the module is already in the kernel sources.

sensors-detect didn't originally find my NCT6793 SIO (Super I/O) . Took some time, but finally discovered the nct6775 module.

thanks for the response

the modprobe command did nothing ( im assuming that it actually worked ) for nct6775

[nankura@nankura-pc ~]$ sudo modprobe nct6775
[nankura@nankura-pc ~]$

i ran another sensor-detect but still yields no results, i guess my board might be it87, i read it87 is in the kernel now to but modprobe doesn't work for that.

Some Super I/O chips contain embedded sensors. We have to write to
standard I/O ports to probe them. This is usually safe.

Or i'm still missing some sort of configuration or setup for nct6775

If it didn't give you an error, it loaded...check with:

lsmod | grep -i nct

If it gives a result (provide output), then run:

sensors

Note: NOT sensors-detect

Provide output.

[nankura@nankura-pc ~]$ lsmod | grep -i nct

i find this interesting though from detect
Trying family `VIA/Winbond/Nuvoton/Fintek'... Yes
Found unknown chip with ID 0xd451
According to the it87 github ( this may apply for nct as well ) the address 0xd451 means something.

The nct6775 module didn't load. :thinking:

do the modprobe again, and immediately the lsmod...nothing in between.

Provide output.

apologies, i was at work and just got home

[nankura@nankura-pc ~]$ sudo modprobe nct6775
[sudo] password for nankura: 
[nankura@nankura-pc ~]$ lsmod | grep -i nct
nct6775                73728  0
hwmon_vid              16384  1 nct6775
pinctrl_amd            32768  0

Ok, now run just sensors; not sensors-detect.

Post output.

it all seems to work now o.o strangely, im not home right now sorry so i didnt get the output but fan speeds, voltages, temps, are all there
