Overclock

The Raspberry Pi supports simple software-based overclocking. There are five overclock profiles for the Raspberry Pi, and two overclock profiles for the Raspberry Pi 2. This options lets you select an overclock profile, or select None to disable overclocking.

Preset ARM CPU Core SDRAM Overvolts
Raspberry Pi
None 700 MHz 250 MHz 400 MHz 0 Volts
Modest 800 MHz 250 MHz 400 MHz 0 Volts
Medium 900 MHz 250 MHz 450 MHz 2 Volts
High 950 MHz 250 MHz 450 MHz 6 Volts
Turbo 1000 MHz 500 MHz 600 MHz 6 Volts
Raspberry Pi 2
None 700 MHz 250 MHz 400 MHz 0 Volts
High 1000 MHz 500 MHz 500 MHz 2 Volts

The default Overclock option is None.

  1. Start on the Raspberry Pi Configuration Performance tab.
    Raspberry Pi Configuration: Interfaces: Performance

    Raspberry Pi Configuration: Performance

     

  2. At the Overclock option, select the desired overclock profile.

Changes won’t be saved until you click OK to exit the Raspberry Pi Configuration tool, and also requires a reboot to take effect.


Enabling an Overclock option makes the following changes to /boot/config.txt
