How to Overclock Your Raspberry Pi 4 to 2.0GHz

on

The Raspberry Pi 4 runs at a default CPU speed of 1.5GHz. With proper cooling, you can safely overclock it to 2.0GHz for better performance in tasks like web browsing, compiling, and retro gaming. Here's how to do it:

Warning:

  • Use a heatsink and fan or a cooling case
  • Make sure your power supply is at least 5V 3A
  • Overclocking may cause instability or overheating

Step-by-Step Guide

1. Open Terminal

Use SSH or the terminal on the Pi itself.

2. Edit the config.txt file

Use the correct file path based on your Raspberry Pi OS version:

  • /boot/config.txt (for older Raspberry Pi OS)
  • /boot/firmware/config.txt (for newer Raspberry Pi OS)

Example command for newer systems:

sudo nano /boot/firmware/config.txt

3. Add the following lines at the bottom:

over_voltage=6
arm_freq=2000

This sets the CPU speed to 2.0GHz with added voltage for stability.

4. Save and exit

Press Ctrl + X, then Y, then Enter.

5. Reboot the system

sudo reboot

Verify the Overclock

lscpu

Look for CPU max MHz: 2000.000 in the output.

Tips for Best Results

  • Monitor temperatures with: vcgencmd measure_temp
  • Use Raspberry Pi OS 64-bit for better performance
  • Stress test your Pi after overclocking

Overclocking your Pi 4 to 2.0GHz can noticeably improve its speed. Just be sure to keep it cool and stable!
