Raspberry Pi 3 のCPUのクロックアップ (オーバークロック)に挑戦してみます。 'Ive just overclocked my Raspberry Pi 3 Model B to 1.3GHz. Here's a brief instruction.

クロックの状態を確認するために、ツールを導入。 Install cpufrequtils in order to check CPU frequency.

pi@pi-top:~ $ sudo apt-get install cpufrequtils

オーバークロックする前の状態。 Here's my RPi3's CPU frequency on normal speed.

pi@pi-top:~ $ cpufreq-info -s -m
600 MHz:13.13%, 1000 MHz:86.87%  (3)

Revise /boot/config.txt 修正。

arm_freq=1300
over_voltage=5
gpu_freq=500
sdram_freq=500
sdram_schmoo=0x02000020
over_voltage_sdram_p=6
over_voltage_sdram_i=4
over_voltage_sdram_c=4

リブートして、確認。 Reboot and see how it goes.

pi@pi-top:~ $ sudo reboot
....
pi@pi-top:~ $ cpufreq-info -s -m
600 MHz:58.64%, 1.30 GHz:41.36%  (7)

どこまでクロックアップできるかは、ハードウエアの個体差や放熱効率にもよります。
