Comme= nt # 58 on bug 10264= 6 from tempel.j= ulian@gmail.com 
I've written a small script to only write into pp_dpm_mclk whe=
n 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=3Dwatch-pp_dpm_mclk
StartLimitIntervalSec=3D0

[Service]
ExecStart=3D.../watch-pp_dpm_mclk.sh
Restart=3Dalways
RestartSec=3D1

[Install]
WantedBy=3Dmulti-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.
