--- Comment #5 from Ivan Avdeev (lists@w23.ru) --- Created attachment 281917 --> https://bugzilla.kernel.org/attachment.cgi?id=281917&action=edit Example of undervolting effect
Example of what happens when undervolting is attempted. Notice how: - frame time goes from stable ~15ms to stuttering 25-30ms - core freq drops from ~1.4GHz to 1.1GHz - memory freq goes from stable ~900MHz to rapidly oscillating between 200-900MHz.
Captured by running Unigine Superposition in game mode on medium setttings on 2560x1440 screen with `GALLIUM_HUD=.d.w1920frametime,.d.w1920shader-clock+memory-clock GALLIUM_HUD_PERIOD=0`
