The stock speed of the A64 is 1.152 GHz. It is not recommended to the overclock the CPU because doing so greatly increases power and thermals and will overheat the device for little to no gain.
The stock speed of the A64 is 1.152 GHz. The A64 can be overclocked to a maximum of 1.344 GHz, it is highly advisable not to do this unless you can also drop the voltage at the same time. The risk of overheating is limited, as the Pinephone will clock down once it reaches 75c.


At 1.344 Ghz the Pinephone feels smoother, especially applications like Geary or Firefox seem to benefit from the overclock. If the CPU is undervolted and overclocked at the same time, it is possible to reach similar thermals and power consumption to the stock configuration but with better performance.

The table above contains measurements created in PostmarketOS (SWMO/SXMO - PostmarketOS 21.12 SP1) with the screen on (set to 50% brightness) under a single threaded load.
{{note|I (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.}}
{{hint|The exact voltages and frequencies that you can achieve will depend on your device. Make sure to run stress tests (such as stress-ng) to ensure stability.}}
