Mojave Random Freezing

[lightingmac]

Possible solution:
In my Deskmini 110 i5 and i7, Clover I tried different graphics ig-platfom-id settings with mixed results. Sometimes stable no freezing but terrible graphics performance and vice versa. Finally just left it empty and its been stable with great 4K playback. Still get occasional black screens, like monitor sleep, that I have to wiggle my usb mouse to get rid of. Anyone have any pointers?

I'm using opencore with ig-platform-id 0x19120000 now, resulting really stable graphics preformance except no HEVC support. When the id is set to normal kabylake id like 0x59120000 or 0x59160000, occasional black screen will come back.
