How to Overclock Your Galaxy Note

If you think that running a pair of 1.4 GHz CPUs on the Galaxy Note is already at peak speed and blazing-fast for the average smartphone, think again. The guys at XDA-Developers have done it again, and this time around they cracked the kernel and have added a few tricks of their own for the Galaxy Note. Thanks to a custom kernel called AbyssNote, you can now underclock the Galaxy Note processor to as low as 50 Mhz or overclock to as high as 1.7 GHz. That’s a ton of battery juice you can save if you ask me–for underclocking, that is.

When it comes to installation of custom made Samsung kernels, many users tend to find it difficult to flash them via ODIN. However, a developer has found an easier method by packing the kernel into a recovery-flashable ZIP file. In other words, the method is the same procedure as installing custom ROMs using ClockworkMod recovery.

In this article, you will learn how to flash AbyssNote to your Galaxy Note.

Requirements

A rooted Galaxy Note
ClockworkMod recovery installed on the phone
AbyssNote Kernel 1.5 or higher

Instructions

Download the latest AbyssNote Kernel 1.5 version. Get it here.
Connect your Galaxy Note to your computer with a USB cable.
Copy the AbyssNote kernel to the root of your phone’s SD card. Make sure that you don’t place the file deep within subfolders so that the file can be easily found.
Reboot your device and enter recovery mode. Make a Nandroid backup, the backup will serve as a contingency plan if anything goes wrong when you flash the kernel.
After making a backup, select “Wipe Cache” then choose “Wipe Dalvik Cache”. Clearing the cache files enables you to have a perfectly clean cache when you flash the custom kernel.
Choose “Install zip from SD card”, then select “Choose zip from SD card”. Navigate through your SD card files and locate the AbyssNote kernel file that you have recently downloaded. Once selected, the flashing process will start. It will take up to 5 – 10 minutes for the process to finish.
After the installation is done, reboot your device.

You can check by installing SetCPU from the Android Market to set your Galaxy Note’s clock speed. Congratulations! You have successfully installed the AbyssNote kernel that will enable you to overclock or underclock your Galaxy Note’s processor.
