Overclocking and underclocking your device’s processor can be very useful in certain circumstances. Overclocking can help aging hardware keep up with newer software, and underclocking (as well as undervolting) can help squeeze more time out of a battery charge.
One of the more popular CPU management applications, Tegrak, received an update recently to make it compatible with Galaxy Note 10.1 and all variants of the Galaxy Note 2. Here are the official change log for the app:
*supports all variants of Galaxy Note II and Galaxy Note 10.1
*fixed bug of the overclock-able max freq on Galaxy S III JB

There are a few fixes for other devices as well, but the main feature addition is support for the Note 2 and 10.1 devices. What’s more, it can overclock and underclock certain stock kernels to an extent. For instance, users have found that they can overclock their Galaxy Note 10.1 to 1.6 GHz to match the clock speed of the Galaxy Note 2. Reports state that anything higher than that will freeze the device. As with any instance in which you run your hardware outside of recommended specifications, there are risks involved, so be sure to be fully appraised of what you’re doing before doing it.
