--- Comment #90 from jeroenimo freedesktop@jeroenimo.nl --- I managed to run glmark2 without crashing the system with
By running the card manual at lowest frequency
from root shell: echo manual > /sys/class/drm/card0/device/power_dpm_force_performance_level echo 0 > /sys/class/drm/card0/device/pp_dpm_sclk
root@jeroenimo-amd:/home/jeroen# cat /sys/class/drm/card0/device/pp_dpm_sclk 0: 214Mhz * 1: 387Mhz 2: 843Mhz 3: 995Mhz 4: 1062Mhz 5: 1108Mhz 6: 1149Mhz 7: 1176Mhz root@jeroenimo-amd:/home/jeroen#
If I go to higher e.g. 2: 843Mhz I manage to crash it.. although it takes a while before it crashes.
when I force the card to anything above 4 I get an immediate crash without even starting glmark2
I hope this helps!
