Well I've been using the CM3 module for the last week and I must say I'm mighty impressed !!!
The Slice has become everything I wanted in a media player/Kodi box.
All the thing that used to take a few seconds to load are instant now.
Every now and then I came across a video file that wouldnt play video/audio in sync.
Thats all in the past now !
Best upgrade ever for the slice in my opinion.
Only downside is that the CM3 module gets a lot hotter and some sort of cooling mod is advised.
But it can be as simple as stacking a few mm of thermal pads onto each other to fill the gap to the top lid.
I've used 1x 5mm pad stacked with 2x 4mm pad to cover the CM3 module.
This way it makes contact with the top lid and the case dissipates the heat.
All cores fully loaded and i havent seen anything above 66-67°
