If there’s any piece of hardware in 2012 that you’re likely to fall in love with, it’s the Raspberry Pi, a sugar-sweet mini computer designed and built in the UK that ships all over the world. Equipped with an ARM processor and capable of running a variety of operating systems (although best results are achieved with a particularly useful Debian build), the Raspberry Pi is small enough to fit in a cigarette box and powerful enough to run a home server, media center, and more.
However, some of these uses could benefit from some extra power — the Raspberry Pi’s «juice» you might say…
Raspberry Pi Hardware
The Raspberry Pi comes with the bare minimum needed to make a usable computer — how else do you think they can make it so small?!
In addition to 256 MB of RAM, the computer is equipped with an ARM11 processor clocked at 700 MHz. This may seem insignificant compared to devices built on AMD and Intel chipsets, but the beauty of the Raspberry Pi lies in its flexibility, not its power. It is this flexibility that makes it easy to overclock. Please note that later versions have increased RAM and more ports and connectivity.
What you need to do to overclock your Raspberry Pi
To overclock your Whiz-Bang micro PC, you first need to install the Raspbian operating system (based on the popular Debian OS). Our previous guide will help you do just that.
If you’ve had a Pi for a while and have been using Raspbian during that time (or downloaded the version referenced in our previous guide), you’ll need to update Raspi-config to add new features to the configuration program. Do this on the command line by typing:
sudo apt-get update && sudo apt-get install raspberrypi * raspi-config
To overclock, select the appropriate option from the Raspi-config menu, and then make your choice from the displayed clock speeds, as shown in the figure.
Note that it is also possible to overclock your Raspberry Pi by creating a config.txt file. Recommended if for some reason you don’t want to update Raspbian OS. Use Notepad++ to change the config file on your Windows machine, available here.
