If you want to increase the power of your device, overclocking is the most effective choice. While all other methods for speeding up the system interact with the processes or use particular tweaks that may have less obvious results, overclocking immediately achieves the desired effect. In this article I will show you all the information about overclocking and how to overclock it on your device.
note: neither I nor AndroidPIT can be held responsible for any errors that may occur during the process.
What the overclock
Each processor (or CPU) has a frequency indicated in GHz: the higher this frequency is, the more operations can be performed in a given period of time. Overclocking means increasing the processor frequency beyond the stated limit. In fact, processors do not run at full capacity. They are limited to guarantee operation at a certain frequency.
Advantages and luck
The advantages are obvious: increasing the frequency of a processor will speed up processes and the entire Android system. But how much can we overclock? It depends on the difference between the maximum processor frequency and the declared frequency. This difference is partly due to the producer's choices and partly luck: CPUs with the same model can be produced with the maximum and the minimum of inaccuracy, guaranteeing both the stated frequency, but only the one with inaccurate results with overclocking. .
Increasing the frequency of a processor, depending on its quality and luck, can cause system instability, crashes and unexpected restart (the screen stays on but no longer responds to touch or the device goes off by itself). Increasing the frequency also increases the CPU temperature, accelerating its deterioration or permanently damaging it. Another problem that cannot be underestimated is the impact on the battery: intense overclocking also increases power consumption.
To overclock a custom Kernel is required. The kernel makes Android communicate with the hardware components of the device (Wi-Fi, screen, CPU), but the standard kernel is not enough. If you have a custom ROM, in 99% of cases you will find a custom kernel integrated. To check, go to Settings > About the phone he was Kernel version. If you find the manufacturer's name (Samsung, LG, etc.), you will have a stock kernel.
- Root permissions: required to get a custom Recovery;
- Custom Recovery: required to flash a custom kernel or custom ROM (with a custom kernel);
- CPU Applications: In the Play Store you will find a variety of applications for managing the CPU and setting overclocking frequency, governor, IO scheduler and other parameters. Among the most famous are No-frills CPU Control.
No-frills CPU Control
- Get root permissions: General Guide and Frequently Asked Questions about root;
- Install a custom Recovery: All About Recovery Mode
- Look for a custom kernel tailored to your device or a custom ROM that has already integrated it. To find a custom kernel, type in Google
custom kernel, custom kernel overclockor something similar. Make sure the custom kernel is compatible with your model and version of Android. To find a custom ROM follow the instructions above replacing kernel with ROM or read our article: the best custom ROMs for your Android;
- Now just flash the custom kernel or custom ROM from Recovery. If you do not know how to do this follow our guide above;
- Most of the work has been done! Now you just have to install an app to manage overclocking, like No-frills CPU Control. If you have flashed a custom ROM it is likely that in the configurations there will be a new section dedicated to overclocking (usually Performance).
Opening a CPU management app we can notice several parameters, but only two related to overclocking:
- Minimum frequency: By increasing it, the system gets ready faster. There is no risk in modifying this value, only higher battery consumption and continuous CPU stress (with the screen off the frequency will continue to be set);
- Maximum frequency: the value that interests us most for overclocking! Depending on the processor and kernel, we may increase the maximum frequency more or less. If you cannot increase the frequency beyond the stated value, try changing the kernel. Of course, besides overclocking it is possible to underclock, lowering the maximum frequency and saving the battery.
What values to set?
As already said, for the minimum frequency there are no problems, while for the maximum it is best to be careful:
- First of all, NO Apply the modifications on restart: in case of problems, simply restart the device to return to normal. Apply modifications to the restart only after testing the settings at length and proving the stability of the system;
- Increase the maximum frequency a little at a time and use various applications to test system stability. If all goes well, you can try more often. At the first sign of trouble, it is sufficient to return the preceding maximum frequency;
- Do not excessively decrease the maximum frequency. Although underclocks are not dangerous, it is possible that too low frequencies will not allow the system to run properly, crashing Android;
- Even if the system is stable, the device may overheat. Download an app to monitor CPU temperature and stop if you see a significant increase.
