Here Are Initial Steps For Configuration of a Raspberry Pi Board and Steps For Overclocking Raspberry Pi. Turbo Mode if available Does Not Affect Warranty. This guide on Overclocking Raspberry Pi is for the new users. Expert users will factually know many small tricks.
Overclocking Raspberry Pi : Make Sure That You Know About Processor and Overclocking
Raspberry Pi 2 Model B is the latest model at the time of publication of this article. It is powered by ARM Cortex-A7 quad-core processor. We talked about ARM Processor and Overclocking before. If you are beginner, you can also read about Raspberry Pi itself.
Overclocking Raspberry Pi : Steps
After the initial start of the Raspberry Pi, it is advisable to check the basic configuration, before heading out to potentially remarkable installations and configurations. In addition, you should also change the user “pi” the default password and make a software upgrade of the system. After that, the configuration of the Raspberry Pi is done. Basic configuration settings can be reached quickly without having to enter complex commands on the command line :
1 | sudo raspi-config |
Depending on the model of the Raspberry Pi, it has a CPU clock rate of 600 or 700 or 900 MHz. If you would like this can be the Raspberry Pi overclock depending on the model above 1000 MHz. You should be aware that overclocking will shorten the life of the Raspberry Pi and may cause system instability. Also, if you have the Turbo Mode, you canchoose from one of five overclock presets in raspi-config. The level of stable overclock you can achieve will depend on your specific Pi and on the quality of your power supply. You need nothing to do more than selecting the options if your board is newer. You will get the text based user interface and can overclock :

If that option is not available, then you’ll work from command line, which is expected in the older models. If your board is older, then :
First cat :
1 | cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq |
A Raspberry Pi 1 (models A, A +, B + and B) by default runs at 700 MHz and is not overclocked, a Raspberry Pi 2 runs at 600 MHz and is overclocked to 700 MHz when needed. Edit this file :
1 | sudo nano /boot/config.txt |
Find the line arm_freq = and change the value by ~8%. Save it. Reboot.
