Need help monitoring CPU temperature in AMD Ryzen 1700

English Hardware
1

Greetings,

I just built a rig with a Ryzen 1700 chip on a Gigabyte AB-Gaming 3 motherboard and I’m having difficulty monitoring the CPU temperature. From what I’ve researched, this is not in the Linux kernel yet so a module has to be added.

Here is the kernel module I need from Git: https://github.com/groeck/it87

sudo make gives me an error:

make[1]: *** /usr/src/linux-4.12.8-1-default: No such file or directory.  Stop. 
make: *** [Makefile:30: modules] Error 2

Here is a tutorial I found but it is all written with the apt command and zypper doesn’t work with the instructions:

https://linuxconfig.org/monitor-amd-ryzen-temperatures-in-linux-with-latest-kernel-modules

I tried changing the make file as instructed but nothing is working.

I’ve never done anything like this before so I may need some hand holding with the process.

I already did sensors-detect which gave me the sensor number I need.

Thanks

Hi
So you haven’t dupped your system to the 4.12.9 kernel yet :wink:

So when you mean sensor number you mean chip, which is? You known you can force the current it87 module with your device id (which is?) to make it work?

https://forums.opensuse.org/showthread.php/524729-Getting-sensors-to-work-on-an-ASUS-Crosshair-VI-Hero-AM4-motherboard?highlight=it87

If that doesn’t work, can make a KMP (Kernel Module Package) for you to install.

Ok, I did a zypper up and I’m on 4.12.9

I ran sensors-detect and it only comes up with two unknown device numbers 0x8686 and 0x8733. Other than that, it says it doesn’t detect anything.

I read through the above thread and tried the modprobe command and got:

modprobe: ERROR: could not insert 'it87': No such device

I’m not really understanding where to go from here. Thanks

Hi
The it87 module is already present in the kernel (I use it with HP M/B), if you try just a modprobe with the id does it load?

See this thread;
https://github.com/groeck/it87/issues/16

I’ve built the module here, but still on the 4.12.8 kernel…

So you need to download the src rpm and rebuild locally as your user, not root!!


wget http://download.opensuse.org/repositories/home:/malcolmlewis:/TESTING/openSUSE_Tumbleweed/src/it87-0+git20170826-1.1.src.rpm
rpmbuild --rebuild it87-0+git20170826-1.1.src.rpm

Then install the kmp rpm as root user and modprobe it87.

You will need to install the kernel-source, kernel-syms, libelf-devel and module-init-tools.

sudo modprobe it87 worked and then I ran sensors which gives:

temp3:        +30.0°C  (low  = +127.0°C, high = +127.0°C)  sensor = thermistor

I did a force id to 8686 and 8622 but this was no different than just loading it87.

I installed two cpu temperature monitor widgets which don’t show the temp yet.

watch -n1 sensors

Seems to work and give information in real time.

Should I download the source rpm that you made and follow your instructions?

I went ahead and downloaded it just to try with your wget command but then got:

rpmbuild --rebuild it87-0+git20170826-1.1.src.rpm 
If 'rpmbuild' is not a typo you can use command-not-found to lookup the package that con
tains it, like this: 
   cnf rpmbuild

Hi
Install the rpmbuild package as well :wink:

Thanks, that was helpful! LOL. Ok, I got everything installed but above you stated: “Then install the kmp rpm as root user and modprobe it87.”

What is the kmp rpm and where do I find it?

Thanks for all your help thus far!

Hi
If you look at the last 10-15 lines of the build output, it will tell you where the rpm is, probably;


/home/<your_username>/rpmbuild/RPMS/x86_64/it87-kmp-default-0+git20170826_k4.12.9_1-0.x86_64.rpm

So as root user;


zypper in /home/<your_username>/rpmbuild/RPMS/x86_64/it87-kmp-default-0+git20170826_k4.12.9_1-0.x86_64.rpm
modprobe -r it87
modprobe it87
sensors

If the output is no different for the kernel one, then remove the rpm and just use the default one.

If it’s not loading on boot, the if you look at the other thread, just need to create an it87.conf file containing it87 and you should be good to go.

It is working now! I found the .rpm and installed it. Created the it87.conf and added it87 to it. Rebooted and sensors shows:

Just one last piece of the puzzle. The two CPU temperature widgets for KDE aren’t showing the temperatures. Do you have any recommendations on what I can use to monitor the temperatures in real time rather than just the sensors command which is a snapshot?

Thanks for all your help!

Hi
I don’t use KDE, so no help there :wink: I use conky (Have a look in the screenshot sub forum). Maybe start a new thread in the applications forum…

Now, the issue you will have is on kernel updates, you need to run through the rebuild from src rpm so it will go back to the kernel updates directory as after a kernel update it will reside in weak-updates, you might see it stop working after a couple of kernel updates until you rebuild it.

I install gkrellm and it is working great for anyone reading this.

Thanks for the heads-up on the kernel updates.

I appreciate all your help!
