How to Overclock the Samsung Galaxy Ace

Samsung Galaxy Ace has been blessed with a root method and a custom recovery, and to add to the development, we now have a overclock kernel for the device. Overclocking means to make your CPU clock run at a faster rate than default and provide you with much better speeds. If you’re interested, here’s how you can overclock your Samsung Galaxy Ace smartphone:

I. Before You Begin:

2. Launch the app from your App Drawer.

3. Hit the Recovery option and you should reboot into the Recovery mode.

4. Once in Recovery, select backup and restore followed by backup.

5. It’ll create the backup of your entire filesystem and save it on your device.

6. You’re done!

III. Downloading Required Files:

1. Download and install either of these apps on your device:


AnTuTu CPU Master

2. Once installed, open the app from your App Drawer.

3. Using the option or slider available in the app, increase your CPU clock speed and keep on doing so as long as your device is comfortable with it.

4. Make sure not to tick-mark the option that says save on boot, it may crash your device.

5. Once you’re stable with a specific CPU speed, close the app.

6. You’re done!

Awesome! You’re now overclocked and all ready to experience a blazing faster performance on your device!

VI. Reverting Back to the Stock Kernel (Optional):

1. Open the Quick Boot app from your App Drawer.

      Let us know how the device performs after overclocking!

      • Eliuth Cruz

        The phone works perfectly with root access and “set CPU”, flashing the kernel is unnecessary.
