I've discovered that changing the gpu governor from 'simple_ondemand' (that seems to be hardcoded at startup into lima driver) to 'performance', set the gpu clock stable to maximum rate, improving overall gui experience.
I've also experimented that
- the gpu is overclockable at 700Mhz (higher clock rate cause hard reset)
- CPU can be overclockable at 1,500Ghz
However, the above clocks settings don't seem to make miracles (at least with kodi).
Could you please explain me how to overclock the cpu?
