The author's android system tablet brain has been used for a while, the tablet is very portable, outdoor use is very convenient, but due to hardware architecture limitations, the performance of the tablet is still not high, once running a high load program, the speed will become Very slow, in fact, the same as the notebook, the overclocking CPU can also greatly increase the speed of the android tablet. 1. Overclocking with SetCPU software To overclock the CPU of the Android tablet, you need to choose a software that is right. Here, the SetCPU software is taken as an example, which can lock the CPU running frequency of the android tablet computer to the set value, thereby achieving the overclocking purpose. 2. Select “Custom Frequency”. Put the SetCPU software into the tablet. After running, select “Custom Frequency” and click “OK” button. At this time, the screen will be black, press “Home” and press to return. If the system does not respond, you need to press the shutdown button to shut down, then restart the tablet. 3. Set the maximum and minimum frequency. Run SetCPU software again and switch to the “Main Interface” window. At this time, you can adjust the maximum and minimum CPU frequency as needed. Take the author's Taipower T720 as an example. The tablet uses a 660MHz CPU. After testing, the highest value can be set to 750MHz, the lowest value is set to 125MHz, and then “Setup Startup” is checked. 4. Select the corresponding working mode to enter the “Scenario” interface, set the working mode when charging to “Minimum”, and set the working mode to “Highest” when using, so that when charging, the CPU will work in 125MHz energy-saving mode. When playing games, the CPU will automatically switch to 750MHz high performance mode. 5, use Widget to overclock the tablet If you are not used to using SetCPU software, you can also use Widget software to overclock the CPU. After running the Widget software, click the "OK" button. Press and hold the "Home" button at the top left of the screen, then select the "Overclocking widget" icon to set the CPU frequency as needed. Enter the "Advanced Settings" interface, you can also customize the CPU operating frequency when the screen is turned on and off. The CPU overclocking method described above is also suitable for use on other android platform tablets, and has versatility. But like overclocking on a computer, overclocking a tablet is equally risky. If the frequency is too high, the tablet will have problems such as abnormal operation and crash. If there is instability, you should reduce the frequency in time. After all, stable operation is more important.
