Hello Geeky, so today we are focusing on How to Safely Overclock Raspberry Pi 4. So please read this tutorial carefully so you may comprehend it in a better helpful way.
Guide: How to Safely Overclock Raspberry Pi 4
The fact that Windows 11 runs on the Raspberry Pi 4 is very successful considering that the specifications of the Raspberry Pi 4 are below the recommended requirements for Microsoft’s new operating system. The fact that Windows is running on the Raspberry Pi is thanks to a unique area of development by Amir Dahan, who created new images and updates for the Raspberry Pi at breakneck speed.
Running at a default speed of 1.5 GHz, Windows 11 on the Pi 4 is a pleasant experience. Sure there are jerks and a few delays, but they can be reduced by using an SSD as boot drive. But what if we wanted to squeeze more than the last task out of Windows 11? To do so, we need to overclock our Raspberry Pi 4, but not through the BIOS, but with Windows on the Raspberry Control Panel developed by Dahan. This easy-to-use tool performs many important adjustments to safely overpower the Raspberry Pi 4.
Overclock Raspberry Pi 4 to 2GHz with Raspberry Pi OS
- First, open the Terminal and execute the command below to: Activate all packages and trusts. sudo apt update && sudo apt upgrade -y
- Then run the command below to: upgrade distro to a new version. This process will take a lot of time, so be patient. sudo shake dist-upgrade
- Once that is done, we need to accept. Updating Raspberry Pi firmware to new version so that we can overcome Raspberry Pi
- If Terminal reads – “rpi update is already a new feature”, you are ready to go. If you update the firmware, you will have to reboot your Raspberry Pi by typing the command – sudo reboot. sudo apt install rpi-update
- Once you have restarted your Raspberry Pi 4, it is time to beat it from 1.5GHz to 2GHz. Open the Terminal and place the order below. It will allow us to configure the file through the Geany editor GUI. sudo geany /boot/config.txt
- Now the Geany window will open. Here, scroll down and find # arm_freq = 800. We need to change the law. First remove the # from the line to execute the command. Then, change the armfreq value from 800 nm 2000. This is a step that will increase the clock speed of your Raspberry Pi 4 processor to 2GHz. You will also need to add a line to increase the tension, which I have described below. Basically the configuration file should look something like this. over_voltage = 6 apa_freq = 2000
- Just in case you want to: overclock the GPU also add the bottom line to the configuration file. Now save the file and delete the Geany editor. over_voltage = 6 apa_freq = 2000 gpu_freq = 750
- Restart your Raspberry Pi and this time you should boot with the overpowering CPU and GPU. To test the numbers, open two Terminal events and run the commands below: any Terminal windows. One lets you track CPU clock speed in real time and the other lets you specify current temperature.
If your Raspberry Pi does not boot after overclocking, follow our solution in the next section below.
clock -n1 vcgencmd measure_clock part -n1 vcgencmd measure_temp
- Now that is set up Our monitoring system, let’s run sysbench to see if the Raspberry Pi 4 reaches 2GHz clock speed. To do this, you need to install sysbench on your Raspberry Pi by ordering below. Press “y” to get the installation. sudo apt install sysbench
- Then run the command below to run the sysbench test. When you run this command, you will notice that the CPU clock speed: touch 2GHz. In my case, I did not install a heat sink and cooler for demo purposes. And well, you can see that the temperature changes around 68 degrees Celsius, which is not normal in this situation. However, we recommend installing a hot tub and cooler on your Raspberry Pi 4 if you want to use the overlay div for an extended period of time. sysbench –num-threads = 8 –test = cpu –cpu-max-prime = 20000 run
- To give you a few numbers: Basically clocked Raspberry Pi 4 (1.5GHz) takes 15 seconds to complete sysbench test. While the 2GHz Raspberry Pi 4 prevailed in just 10 minutes. Even while exporting videos and videos play in the browser, you will see a big difference in performance, thanks to the overpowering GPU.
- If you want to remove the redundant CPU and GPU on the Raspberry Pi, run the command below again to open the configuration file. sudo geany /boot/config.txt
- Go to the same section where you have already changed the values. Here, to add # to all new lines and save the file. This will undo the commands and load your Raspberry Pi at your default clock speed after reboot.
