How To Overclock Your NOOK Color

Posted by techhackz-admin Saturday, January 22, 2011


Barnes and Noble has created a monster with the NOOK Color! It is a great eReader and in addition to that it does make a pretty good and cheap Android tablet once it is rooted. And now it even got better as it has been overclocked successfully to up to 950 MHz. This does require a rooted Nook Color and a custom kernel from our friends @ XDA.

Please note that we won't be responsible if you end up bricking your device. Rooting or customizing your device can be risky, if you follow the instructions you should be fine!

In order to overclock your device you will first need to root it, to do so you can follow our instructions at How To Root Your Nook Color.

Check out the Quadrant score obtained by camwinnn @ XDA using the Quickie “Screamer” kernel, quite impressive:


There are 2 kernels available:

  • One for the stock 2.1 Nook Color, you can find the files @ [KERNEL] [ZIP] Quickie - Flashable Overclock Kernel - "Screamer"
  • One for Android 2.2 (Froyo), you can find the files @ [KERNEL] [WIP] Quickie "Screamer" 0.1 for Froyo!

Both kernels offer similar features [from [KERNEL] [ZIP] Quickie - Flashable Overclock Kernel - "Screamer"]:

  • All steps undervolted about 25%. Should be stable still
  • The table is currently 300, 600, 950mhz until I can make it scale more than 3 steps.
  • The voltage for 950Mhz is less than at stock for 800Mhz, so you should see better battery life even though we're overclocked.
  • Display flicker fixed (or at least toned down, it can't be completely eliminated with the LED backlighting)
  • Scheduler tweaks backported from later kernel versions
  • Some governor tweaks of my own for responsiveness
