Low CPU frequency and the laptop get slow

Post by fedega »

Hello my driends,
I use my laptop for high speed software.
I have try to use some guide for edit grup, /sys/devices/system/cpu/......, CPUpower, etc... But I can't keep a constant frequency.
Often when I have more load the CPUs are lowered in frequency and the Laptpo becomes unusable. :evil: :twisted:

There is no frequency and power manager like in windows, or like some ubuntu tools.

Do you have a solution? fast and safe to keep my CPUs at peak frequency?

Then I recommend creating a noteworthy CPU Manager ... if it exists for WIndows, I don't see why it shouldn't exist for Linux.

thank you so much
I look forward to it confidently.

Your CPU will run at max speed, but if the fans can't keep stop it overheating, then it will reduce the frequency to reduce the power consumption.
Otherwise your CPU will overheat and do a hard shutdown.

try running inxi -sC to get a display of temperature/speed.

There's laptop-mode-tools and powertop which work okay together. Make sure you aren't already running tlp if you try laptop-mode-tools.

Hello
the problem is simple
I have the governor as a performance:

Then
xxxxxx: ~ $ sudo cpupower frequency-set -u 24000000
CPU setting: 0
CPU setting: 1
CPU setting: 2

xxxx: ~ $ sudo cpupower frequency-set -u 24000000
CPU setting: 0
CPU setting: 1
CPU setting: 2

In theory, the CPUs should remain at maximum.
This happens on the Ubuntu-based version, and on ubuntu.
On Linux Mint 19 Tara, no ...
Does not work.
Usual laptop machine, same bios configurations, etc.

Thanks

check if there is a file called /etc/default/tlp

if there is, you can alter it to force a minimum frequency the same as your maximum.

but like axisofevil says, your laptop will throttle itself if it gets too hot anyway.

since this has nothing to do with LMDE, ask a moderator to move your topic into the main edition support threads and it may get more attention from the gurus who don't come in this section of the forum.
