Hi together,
did testing Option 1 - but still the System freeze and no chance to get some
relevant output in the log.
~# cat /sys/class/drm/card0/gt_RPn_freq_mhz
167
~# cat /sys/class/drm/card0/gt_max_freq_mhz
854
~# echo "167" >/sys/class/drm/card0/gt_max_freq_mhz
~# cat
/sys/class/drm/card0/gt_max_freq_mhz
167
kind regards
Juergen</pre>
