Hi,
I have a Dell Precision 5560 with Intel i7-11800H.
I have installed Fedora 35 but I noticed that the cpu is stuck at 2.50 GHz and the only cpu governor available are performance and powersave:
What is the output of inxi -Cxx?
That should give the minimum and maximum cpu freq plus the current operating freq for each core.
My desktop with a rhyzen 5 cpu shows this
Hi, just for note, by using cat it’s only capture the value at the time we run the cat. The other hands, if displaying the value from specific app (GUI/TUI), they also capturing the value at certain interval and not realtime.
Above approach are to get as close as possible the time when get the snapshot of cpu speed.
The htop it self I believe only tool to display the information that already available from the system by reading it. It also possible that htop failed to read the info.
But if you believe that there no different between powersave and performance, maybe you also want to check the bios setting if there any specific setting that control your cpu speed (power management) that make the OS failed to overwrite it.
Once I disabled “Intel Speed Shift Technology”, frequency is scaling and I can see more governor.
Funny enough:
This option is used to enable/disable Intel Speed-Shift Technology. Setting this option to enable allows the operating system to select the appropriate processor performance automatically.
