The table originates from Armbian, but the maximum voltage is raised slightly to account for boards using slightly higher voltages. This has been tested on the Libre Computer ALL-H3-CC-H5 and the Bananapi M2+ v1.2 H5, both with adequate cooling. The former has a fixed 1.2V regulator, while the latter has a GPIO controlled regulator switchable between 1.1V and 1.3V.
