Is there a temperature sensing utility for linux that will read a ryzen 1700 cpu?

Question

Is there a temperature sensing utility for linux that will read a ryzen 1700 cpu? I have been looking for such a utility and cannot find one. Psensor and xsensor does not work, nor does lm-sensor. The bios of the motherboard (GA-AB350M-Gaming 3) reads temps ok, but that is only when I am in the bios and not the running the os.

How can I get this to work?

Solution 1

The kernel module that worked for me is it87 https://github.com/groeck/it87

I have an ASUS Crosshair Hero VI. https://rog.asus.com/forum/showthread.php?92313-linux-lm_sensors-it87-driver

I am using ArchLinux with the 4.11 kernel. To get it working I ran

sudo modprobe it87 force_id=0x8622
sudo sensors-detect

You may need to use a different force_id value. The recommended list from the repo is 0x8622, 0x8628, 0x8728, and 0x8732.

To get the module loaded at boot time I had to create the following files as root.

# /etc/modules-load.d/it87.conf
# Load it87 for Ryzen motherboard and CPU sensors
it87

# /etc/modprobe.d/it87.conf
options it87 force_id=0x8622

Solution 2

I have an exact Ryzen 1700 and did the below instruction found on forums to see the temperature sensors.

I have an Ubuntu 17.04 with kernel 4.11.3 and an Asus X370 PRO mobo. and this does not work for me but you can try these commands and leave a reply in the comments.

sudo apt-get install lm-sensors git
sudo apt-get install linux-headers-`uname -r`
git clone https://github.com/groeck/nct6775
cd nct6775/
make
sudo cp /proc/kallsyms /boot/System.map-`uname -r`;
sudo make install
sudo modprobe nct6775
sudo sensors-detect
watch -n1 sensors

alternatively you can try:

sudo apt-get install lm-sensors git
sudo apt-get install linux-headers-`uname -r`
git clone git://github.com/groeck/it87.git
cd it87
make
sudo cp /proc/kallsyms /boot/System.map-`uname -r`;
sudo make install
sudo modprobe it87
sudo sensors-detect
watch -n1 sensors

We only support official versions of Ubuntu. Besides that: Datasheet for Family 17h CPUs is not published by AMD so the maintainers of those sensor programs can not fix this until this is release.

The it87.ko driver is too old and does not support newer chipsets bugs.launchpad.net/ubuntu/+source/linux/+bug/1740736

Thanks! I have a Ryzen 1700 and ASRock AB350M mobo. Using kernel 4.9. I believe the nct6775 module from Git only provides the motherboard's temperature reading of the CPU, not the internal temperature of the CPU: pastebin.com/JRV2xBrc I believe this is what CPUTIN is. For me at least, getting the it87 module working is probably essential. More discussion here: reddit.com/r/Amd/comments/68lyug/ryzen_issues_on_linux

In my case, the chip is probably a Nuvoton, not ITE. Appropriate module: github.com/groeck/nct6775 Nuvoton discussion: github.com/groeck/nct6775/issues/49

I have a 1600X and an MSI B350 GAMING PRO CARBON, works for me! Debian with Kernel 4.11
