Title: CPU scaling
Post by: neggard on May 28, 2019, 11:40:42 am
I have search forum and internet for changing the governor to performace.
I have found some program like cpupower and cpufrequtils

But is peppermint 10 shipping with a cpu scaling utility already?

I want my cpu to always have governor performance.

it does not - to the best of my knowledge.

That would fall under the guise of  "user choice" and not a "must have" to work

Both should be achievable though by following any tutorials on their respective installs

I have tried many guides but no luck.

type this in a terminal

Code: [Select]
sudo apt-get install -y indicator-cpufreq

Reboot and then right click the icon in the Notifications area and choose either powersave or performance

Working here on Peppermint 10

ps I have no idea how to measure it to see if it actually does anything to the CPU power

Thanks.
I use lscpu to see the speed. I have a  i7-4790, Base Frequency 3.60 GHz and  Max Turbo Frequency 4.00 GHz
The lscpu command give me 3.6 GHz when I have performance.
How could I set performace to be my default value at startup?

Is is possible to force the cpu to use the max turbo frequency all the time?

No idea - sorry

You will need to wait for the real clever members of the forum to reply

Maybe if you want to use it as a heater.

Why do you need this?!
You have an i7 quadcore with hyperthreading. Are you compiling from source a lot of large stuff?
Anyway, your call... try overclocking it, but its not any good for it.

I wouldn't want a CPU running flat out permanently (even worse in turbo mode permanently) .. modern CPU's are designed to automatically frequency scale depending on load, let it do its job.

You won't see a performance benefit of locking it to performance mode (it'll jump to that when needed anyway) .. you'll just be wasting electricity.

Yes you are right, jthe CPU handle it good BUT
When you play high FPS games the CPU cant handle it fast enough, when that happend
the FPS drops fast and strange things happend in the game.
I am talking about CS:GO now (Counter-strike).

Many player want at least 300steady FPS.
