I've written a small script to only write into pp_dpm_mclk when it's not forced into pstate 2: #!/bin/bash if ! cat /sys/class/drm/card0/device/pp_dpm_mclk | grep -xqFe "2: 2250Mhz *" then echo "2" > /sys/class/drm/card0/device/pp_dpm_mclk fi --- Can be restarted every 1s via systemd: [Unit] Description=watch-pp_dpm_mclk StartLimitIntervalSec=0 [Service] ExecStart=.../watch-pp_dpm_mclk.sh Restart=always RestartSec=1 [Install] WantedBy=multi-user.target --- Seems to do the trick without nasty side effects. Real fixes for the memory clock change flicker and the not sticking pp_dpm_mclk value would of course be better.
