Title:
Ryzen 3550h lowers its frequency to 400MHz
Status in linux package in Ubuntu:
Expired
Bug description:
I've bougt new notebook with ryzen 3550h onboard (Asus fx705dy) and
noticed one thing: whenever the cpu is fully loaded and the gpu is
being used the cpu sets its freqeuncy to 400MHz and system works slow
untill reboot.
For example:I installed Android Studio. When I open large project in
it and open youtube video in browser or start emulator system works on
max frequency for couple of seconds and then lowers cpu frequency to
400MHz. If I just compile the project it'll work nice until using gpu.
Another example is I can compile Unreal Engine within 1.5 hours
without such problems if I just let notebook do it without browsing
internet.
I've tried a lot of things like settings cpufreq mode to performance
(sudo cpufreq-set -r -g performance), disabling c6 state etc.
The only workaround I found for now is disabling boost for cpu by executing
echo 0 > /sys/devices/system/cpu/cpufreq/boost
Any idea how to work on this system without disabling cpu boost?
