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. | The stock speed of the A64 is 1.152 GHz.

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. | |||

{{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.}} | {{note|I (somefoo) was able to undervolt the Pinephone at each frequency operation point by at least -100mv.
