How to Safely Overclock Raspberry Pi 4 2024

The Raspberry Pi 4 is a versatile single-board computer that can be used for a wide range of applications. With its powerful processor and ample memory, it is capable of handling demanding tasks. However, if you want to push the limits of its performance even further, you can overclock it. Overclocking refers to increasing the clock speed of the processor beyond its default value to achieve higher performance. In this article, I will guide you on how to safely overclock your Raspberry Pi 4, ensuring that you get the most out of this tiny powerhouse without damaging it.

Notable Points to Remember Before You Overclock Raspberry Pi 4

Before you proceed with overclocking your Raspberry Pi 4, there are a few important points to keep in mind. Overclocking can increase the power consumption and heat generated by the processor, so you need to ensure that you have proper cooling measures in place. A passive heatsink or an active cooling solution like a fan is highly recommended to prevent overheating.

Additionally, overclocking your Raspberry Pi 4 may void its warranty, so it’s important to understand the risks involved. While the Raspberry Pi Foundation has designed the Pi 4 with some headroom for overclocking, pushing it too far can lead to stability issues and even permanent damage. It’s crucial to proceed with caution and take gradual steps when overclocking.

Overclock Raspberry Pi 4 to 2GHz Using Raspberry Pi OS

To overclock your Raspberry Pi 4 to 2GHz, you can use the Raspberry Pi OS, which is the official operating system for the Pi. Follow these steps to safely overclock your Pi 4:

1. Update your Raspberry Pi OS to the latest version by running the following commands in the terminal:

sudo apt update
sudo apt upgrade

2. Open the config.txt file by running the following command:

sudo nano /boot/config.txt

3. Scroll down to the bottom of the file and add the following lines:

over_voltage=4
arm_freq=2000

4. Save the changes by pressing Ctrl + X, followed by Y, and then Enter.
5. Reboot your Raspberry Pi 4 for the changes to take effect:

sudo reboot

Once your Pi 4 restarts, it will be running at 2GHz. You can verify the new clock speed by running the command vcgencmd measure_clock arm.

Raspberry Pi 4 Not Booting After Overclocking? Here is the Fix!

If your Raspberry Pi 4 fails to boot after overclocking, don’t panic. This can happen if the overclocking settings are too aggressive for your particular Pi. Here’s a fix that you can try:

1. Disconnect the power supply from your Raspberry Pi 4 and let it cool down for a few minutes.
2. Remove the microSD card from your Pi 4 and insert it into a computer running the Raspberry Pi OS.
3. Open the config.txt file located on the microSD card.
4. Look for the lines that you added for overclocking and comment them out by placing a # at the beginning of each line.
5. Save the changes and safely eject the microSD card from your computer.
6. Reinsert the microSD card into your Raspberry Pi 4 and reconnect the power supply.

Your Pi 4 should now boot successfully with the default clock speed. You can then try a more conservative overclocking configuration or experiment with different settings to find a stable overclock.

Overclock Raspberry Pi 4 to 2.1GHz Running Windows 11/10

If you’re running Windows 11 or 10 on your Raspberry Pi 4, you can still overclock it to achieve higher performance. Follow these steps:

1. Install the Raspberry Pi Imager on your Windows computer if you haven’t already. You can download it from the official Raspberry Pi website.
2. Insert a microSD card into your computer and open the Raspberry Pi Imager.
3. Select the appropriate Raspberry Pi OS version for your Pi 4 and click on “Choose SD Card” to select the microSD card.
4. Click on “Advanced Options” and enable the “Overclock” option.
5. Set the desired clock frequency, such as 2100MHz, and click on “Write” to write the Raspberry Pi OS image to the microSD card.
6. Once the image is written, insert the microSD card into your Raspberry Pi 4 and power it on.

Windows 11 or 10 should now run on your overclocked Raspberry Pi 4 at the specified clock speed. Keep in mind the cooling requirements mentioned earlier to ensure the stability of your overclock.
