First Bootįor the changes to take effect reboot the Pi by either: These overclock parameters are explained in detail on the official Raspberry Pi site. To save the changes use CTRL-X, then Y followed by ENTER. Your config.txt file should now look something like this : If there is a leading # character then remove that.Ībove the “arm_freq” line add the following: over_voltage=6 If you aren’t already at the command prompt launch a terminal window.įind the “arm_freq” line and change it to: arm_freq=2000 Please ensure you are comfortable with that risk before proceeding. Simon Martin, 3rd Nov 2020,Īlthough some users have managed to get the Pi 400 to run at 2.2GHz I decided to try a more modest overclock of 2GHz as I believe that this is more in the spirit of what Simon was suggesting.ĭisclaimer : Overclocking any computer comes with some risk. In fact, there is enough thermal margin to overclock it, if you’re so inclined. Raspberry Pi 400 contains a heat spreader that dissipates the heat across the whole unit, front and back, so that no part of it will feel too hot to touch. We’ve solved the cooling challenge so users don’t have to give this any thought. In a Pi Foundation blog post Simon Martin stated, Not only does this allow the Pi 400 to run at 1.8GHz out the box but it also allows for some easy overclocking.
This has been achieved with careful PCB design and a massive heat-sink. The Pi 400 has been designed to be used without any active cooling. Overclocking the Raspberry Pi 400 is easy and gives you an extra performance boost for free.
