tbsky Posted May 8, 2020 Share Posted May 8, 2020 Hi: I am new to Armbian Buster. I understand the legacy h3consumption is gone now. I wonder if I can do something similar under Armbian Buster like: 1. only allow 1 or 2 core 2. lower ram frequency 3. disable hdmi Link to comment Share on other sites More sharing options...
