I am using fedora 34 with gnome and the cpufreq extension to control the execution speed of the cpu of a computer.

I have configured it to run in power saving mode, thus when doing nothing the cpu clock is about 600mhz when i configure the extension to use "1%" as minimum.

I would like to know if i can lower even more the cpu clock. Is there any chance to meet undesirable bugs ? Would this be more appropriate for even more power saving ?

    What model CPU do you have (and what motherboard)? I posit that you cant go lower then 600 because thr CPU wont support it. If you more power savings and hardware supports it, maybe you need to be looking at a lower-then-os level like undervolting and/or sleep states.

  • Why are you trying to "save power"? Reduce heat generation? Save on energy bill? For the latter, proper PSU sizing is probably more important.

  • @sawdust Reduce heat generation? Save on energy bill? heat definitely. saving on energy bill is not bad either ; )

    I don't have an answer for you, but from askubuntu.com/questions/1202352/… you should be able to set the frequency to 400Mhz on this cpu. (No idea how accurate that is)

    At the level of 400 or 600mhz, your power savings and additional heat disipation are going to be almost immeasurable, and I'd be surprised if you saved as much as $1 per year.
