I am unable to access most sensor data in Ubuntu using Psensor or Xsensors on Ubuntu 14.04 on GA-970A-D3P board with an AMD FX 6350 CPU. I cannot access GPU temperature, the individual temperature of each CPU core, fan speeds or voltages.

I also cannot display SPD Data during memtest, I get “SMbus Controller Not Known” though I was able to get that data in Ubuntu using decode-dimms.

I can however, access the overall temperature and CPU usage. On “System monitor” I can get the CPU history of each core. Running 'sensors-detect' did not allow access to remaining sensors either.

This is a dual boot machine with windows 7. On Windows I can access GPU temperature and fan speed, overall 1 – 6 CPU temperature (but not each individual core temperature), GPU voltages and clock speeds and SPD Data.

Can anyone suggest a fix?

  • I'm guessing you installed lm-sensors because you ran sensors-detect. Is this correct? – mchid Jun 29 '15 at 8:49
  • also, can you access these values using the sensors command – mchid Jun 29 '15 at 8:50
  • Yes lm-sensors was the lates version when i checked before. Sensors only shows power 1 and temp 1 when i do sensors. – Zabooty Jun 29 '15 at 14:36

The package responsible for detecting sensors in 14.04 is libsensors4 which is developed together with lm-sensors and sensors-detect. People there are really trying hard to keep pace with new hardware integration but this will not always include all possible sensors out there.

From an overview of supported devices we have the impression that the AMD 'Vishera' processors were not yet included. Nevertheless it may be worth to try a nupgrade both libsensors, and sensors-detect to the most recent version if running on newer hardware.

There is no guarantee that sensors of a specifc device will be detected thenafter. We can not test this here for obvious reasons.

Also note that updating the package included in Ubuntu may need considerable time to include newer upstream releases. At the time of writing the upstream stable version is a 3.4.0 (released 4 days ago) whereas the version from 14.04 still is a 3.3.4.

  • libsensors4 is already the latest version – Zabooty Jun 29 '15 at 14:52
  • as said, it may not be supported then (I am sadly having the same issue with AMD A8-6500 on a Gigabyte GA-F2A88XN) – Takkat Jun 29 '15 at 20:01
