If you unwrapped a Raspberry Pi for the holidays or grabbed one to tinker with yourself, we already have some great projects you can try. If you wish your Raspberry Pi had a little more juice for that XBMC media center or arcade table, it’s not too hard to overclock it.
Over at Jeremy Morgan’s .NET blog, he walks you through the process of finding your Raspberry Pi’s current clock speed via command line, and then how to overclock the device simply by adding two lines specifying your desired speed for the processor and onboard memory to your Raspberry Pi’s config file. In some cases, it’s that simple. He notes that your mileage may vary with that technique, but if it works for you, you’ve successfully overclocked without voiding your warranty.
If that doesn’t work, he proposes you update your firmware, install the raspi-config utility, and use that instead, since it has a built-in tool for overclocking. That’s the method that worked for Jeremy in the end. For a full walkthrough, complete with step-by-step commands, hit the link below.
