We know that the Barnes & Noble NOOKcolor reader was recently seen running Ubuntu Linux, but here is yet another mod done to said reader which might just stoke your interest in purchasing one if you haven’t done so already. This $250 tablet has just been overclocked, hitting at least 950 MHz in speed or faster if you want to – which is a pretty respectable jump from the stock 800 MHz in which it comes in. This is made possible only with the installation of a custom kernel, where it allows you to reduce the voltage and increase the clock speed, resulting in a far speedier machine without compromising on its power, translating to a better battery life, of course. On paper, the NOOKcolor should be able to be overclocked to run at 1 GHz, although users did report difficulty getting things to work properly at that speed. Go ahead with this overclocking project only if you’re pretty sure that you know what you’re doing, otherwise just steer clear.
