How to Overclock a Raspberry Pi Zero W

In a previous article I described how to overclock a Raspberry Pi 3 or 4; today I will explain how to do it on a Raspberry Pi Zero.

The procedure is very similar to the Raspberry Pi 3 or 4 guide, but with slightly different parameters.
Simply edit the config.txt file in the boot partition with the following command:

sudo nano /boot/config.txt

and enter the following:

arm_freq=1095         #con un dissipatore passivo
gpu_freq=550          #con un dissipatore passivo
over_voltage=2
core_freq=515
sdram_freq=533
over_voltage_sdram=1

Once you have pasted the text, close the file by pressing CTRL+X, then type Y (or S, depending on your system language) and finally press ENTER to confirm.

To apply the change immediately, restart the Raspberry Pi with the following command:

sudo reboot now

If you find that the Raspberry Pi doesn’t boot or something hasn’t gone as planned, you can always remove the microSD card from the Raspberry Pi, connect it to any computer and restore the config.txt file from there

Enjoy!
