The table above shows the valid voltages provided by the AXP803 PMIC on DCDC2 (used to power the cores). For example, setting the voltage to 0.60V is valid, but setting it to 1.23V is not. When overclocking, ensure that you only use valid voltages at each operation point (otherwise it will simply be dropped and ignored). You can use (after installing) cpupower to display all valid frequencies after boot. | |||
{{note|The user ''somefoo'' was able to undervolt the PinePhone at each frequency operation point by at least -100mv. The A64 set to 1.152Ghz runs at 1.18v instead of the standard 1.3v, dropping the power usage by ~0.7w under full single threaded load! The silicon lottery will dictate how well you can undervolt.}} | {{note|The user ''somefoo'' was able to undervolt the PinePhone at each frequency operation point by at least -100mv.
