I want to speed up the image processing and one idea that comes to my mind is overclocking but I only have 5v supply and 2A limitation on my psu can I overclock my Pi 3 withou overvoltage or overcurrent?

  • What OS are you running on your Pi? – Darth Vader Jan 23 '17 at 15:23

  • @DmitryGrigoryev your answer is outdated what about raspi 3 i saw that the question was asked and answered 4 years ago. what about raspberry pi 3. i went to raspi-config and the overclocking section is not applicable – wayne Jan 23 '17 at 16:22
  • @wayne That answer doesn't even mention raspi-config. Read it. This blog specifically states that arm_freq parameter still works for RPi 3. – Dmitry Grigoryev Jan 23 '17 at 16:30

You could easily overclock your Raspberry Pi 3 but please keep in mind that with great power comes great responsibility. 😋

There is an article here from the RetroPie git repo which tells you all about the instructions and information about overclocking.

You can try it out by modifying the overclock settings in config.txt. But please stay within the limits mentioned by the link above: we're not responsible for any damage caused by this. You would probably want to edit the values for GPU and CPU.

sudo nano /boot/config.txt

Please also note that there are some settings which flip a hardware switch inside the Pi and void the warranty, these are:

  • over_voltage greater than 6
  • force_turbo=1
  • temp_limit greater than 85

Open the terminal and type sudo nano /boot/config.txt.

Find: #arm_freq=800, delete the # and change 800 to whatever speed you want with a max of 1400, but that is not recommended.

This is what mine looks like: arm_freq=1300.

Hope it helps!

  • thank you for the info :) are you using pi 3?? – wayne Jan 24 '17 at 0:37
