Since the Raspberry Pi’s release, it hasn’t been uncommon for people to overvolt and overclock their Pi’s to get a little extra oomph for day to day tasks. Linux User’s Editor Russell Barnes has even had a look at it, reporting that there was no discernable heat increase on his board. Now this unofficial power boost is becoming official, with newer distro images coming with the ability to let you turn on turbo mode.
There are now five overlock presets in raspi-config, which will increase the processors speed to 1 GHz at its highest level. In tests performed by the Raspberry Pi Foundation, they found a 50% increase in performance, and the best part is it won’t void your warranty. In a blog about it, they do advise in using a decent power supply while testing this.
Updating should get you the updated config file, but if not you can grab an image from the RPi website.
