Steps to Overclock your Raspberry Pi 4<\/strong><\/h2>\n\n\n\n<\/div>\n\n\n\nWarranty and Risks<\/strong><\/h3>\n\n\n\n<\/div>\n\n\n\nIn most cases, overclocking is safe and will not void your warranty if done so in an appropriate manner<\/strong>. However, you should still be aware that there are several settings that will void the warranty by flipping a hardware switch inside your Pi:<\/p>\n\n\n\n- over_voltage greater than 6<\/li>
- force_turbo=1<\/li>
- temp_limit greater than 85<\/li><\/ul>\n\n\n\n<\/div>\n\n\n\n
There will always be a risk of your Raspberry Pi 4 overheating while being overclocked. This tutorial will teach you the safest method, but please be aware of and accept the risks that you will undertake by continuing!<\/p>\n\n\n\n
<\/div>\n\n\n\n
\n\n\n\n<\/div>\n\n\n\nStep 1: Prepare the Hardware<\/strong><\/h3>\n\n\n\n<\/div>\n\n\n\nBefore we get started, let\u2019s first go through what you\u2019ll need for this tutorial. Apart from your R<\/a>asp<\/a>berry Pi 4<\/a>, you\u2019ll need:<\/p>\n\n\n\n- A Raspberry Pi 4 Cooling Solution – Heatsink + Fan recommended<\/li>
- SD Card with Raspberry Pi OS Installed<\/li>
- A Reliable Power Supply<\/a> (official version is highly recommended) to ensure your Pi is not being starved of power<\/li><\/ul>\n\n\n\n<\/div>\n\n\n\n
Recommended Cooling Solution: <\/strong>Black Warrior ICE Tower CPU Cooling Fan<\/strong><\/a><\/h3>\n\n\n\n<\/div>\n\n\n\nUndoubtedly the biggest issue with the Raspberry Pi 4 is thermal issues and throttling. With the Pi 4 capable of reaching insane temperatures (even beyond 85\u00b0C) without overclocking, you\u2019ll definitely need a cooling solution in place if you want to overclock it!<\/p>\n\n\n\n

This will give you the latest performance and reliability optimisations offered, which will improve your ability to reach higher clock speeds!<\/p>\n\n\n\n
<\/div>\n\n\n\nHere\u2019s how you can update your Pi 4 to the latest firmware:<\/p>\n\n\n\n
<\/div>\n\n\n\n- Open the terminal on your Raspberry Pi and enter the following code:<\/li><\/ol>\n\n\n\n<\/div>\n\n\n\n
sudo apt update\n\nsudo apt full-upgrade<\/code><\/pre>\n\n\n\n<\/div>\n\n\n\n![\"\"](\"https:\/\/www.seeedstudio.com\/blog\/wp-content\/uploads\/2022\/03\/1.1-2.jpg\")
Source: Cytron<\/a><\/em><\/figcaption><\/figure><\/div>\n\n\n\n2. Afterwards, reboot the system for the update to be applied!<\/p>\n\n\n\n
<\/div>\n\n\n\nsudo reboot<\/code><\/pre>\n\n\n\n<\/div>\n\n\n\nStep 3: Check the Default Speed of CPU<\/strong><\/h3>\n\n\n\n<\/div>\n\n\n\nThe next step before you overclock your Pi 4 is to check your CPU base speed. It is good to check the default clock speed to see the changeable value, which can be done by opening the command line and entering the following:<\/p>\n\n\n\n
<\/div>\n\n\n\nLscpu<\/code><\/pre>\n\n\n\n<\/div>\n\n\n\nor<\/p>\n\n\n\n
<\/div>\n\n\n\ncat \/sys\/devices\/system\/cpu\/cpu0\/cpufreq\/scaling_cur_freq<\/code><\/pre>\n\n\n\n<\/div>\n\n\n\n![\"\"](\"https:\/\/www.seeedstudio.com\/blog\/wp-content\/uploads\/2022\/03\/2.1-1.jpg\")
Source: Cytron<\/a><\/em><\/figcaption><\/figure><\/div>\n\n\n\n<\/div>\n\n\n\nThis indicates that my Pi 4 CPU base speed is 600MHz, the speed requested by the kernel!<\/p>\n\n\n\n
<\/div>\n\n\n\nStep 4: Let\u2019s start overclocking!<\/strong><\/h3>\n\n\n\n<\/div>\n\n\n\nTo overclock your Pi 4, we\u2019ll mainly be tinkering with the config.txt file<\/strong> under core configuration settings. Follow the instructions below carefully to avoid any errors.<\/p>\n\n\n\n<\/div>\n\n\n\n- Open your terminal window and enter the following code:<\/li><\/ul>\n\n\n\n<\/div>\n\n\n\n
sudo nano \/boot\/config.txt<\/code><\/pre>\n\n\n\n<\/div>\n\n\n\n<\/div>\n\n\n\n- Scroll down to the section marked:<\/li><\/ul>\n\n\n\n<\/div>\n\n\n\n
#uncomment to overclock the arm. 700 MHz is the default.\n#arm_freq=800<\/code><\/pre>\n\n\n\n<\/div>\n\n\n\n- Change the config settings to:<\/li><\/ul>\n\n\n\n<\/div>\n\n\n\n
#uncomment to overclock the arm. 700 MHz is the default.\nover_voltage=2\narm_freq=1750<\/code><\/pre>\n\n\n\n<\/div>\n\n\n\n- Save the file with CTRL+O (press RETURN) and use CTRL+X to exit. Now, restart your Raspberry Pi:<\/li><\/ul>\n\n\n\n<\/div>\n\n\n\n
sudo reboot<\/code><\/pre>\n\n\n\n<\/div>\n\n\n\n- Once your Raspberry Pi boots up again, use the vcgencmd command to check your new, faster clock speed:<\/li><\/ul>\n\n\n\n<\/div>\n\n\n\n
watch -n 1 vcgencmd measure_clock arm<\/code><\/pre>\n\n\n\n<\/div>\n\n\n\nThis command will monitor your real-time speed. Browse a few web pages on a few tabs and watch your CPU head on up to 1.75GHz!<\/p>\n\n\n\n
<\/div>\n\n\n\nStep 5: Overclocking your Pi 4 to even higher clock speed (2GHz)!<\/strong><\/h3>\n\n\n\n<\/div>\n\n\n\nIf you think overclocking it to around 1.75GHz is impressive, let\u2019s take things up a notch, by cranking your Pi 4 CPU to 2.0GHz.<\/p>\n\n\n\n
<\/div>\n\n\n\nWe will need to increase over_voltage to adjust the core CPU\/GPU voltage to accommodate the higher clock speed. We will be cranking the over_voltage value up to 6, which is the highest without voiding the warranty<\/strong>.<\/p>\n\n\n\n<\/div>\n\n\n\n- Edit the config.txt file with the following settings:<\/li><\/ul>\n\n\n\n<\/div>\n\n\n\n
over_voltage=6\narm_freq=2000<\/code><\/pre>\n\n\n\n<\/div>\n\n\n\n- Save the file and exit Nano by CTRL+O and CTRL+X. Reboot your Raspberry Pi 4 and run:<\/li><\/ul>\n\n\n\n<\/div>\n\n\n\n
sudo reboot\nwatch -n 1 vcgencmd measure_clock arm<\/code><\/pre>\n\n\n\n<\/div>\n\n\n\nSimilar to before, you’ll now see the clock speed limit to appear as 2.0GHz!<\/p>\n\n\n\n
<\/div>\n\n\n\nStep 6: Overclocking your Pi 4 to the Max level!<\/strong><\/h3>\n\n\n\n<\/div>\n\n\n\nNow for the moment you\u2019ve been waiting for, overclocking your Pi 4 to 2.147GHz max clock speed! This time, we\u2019ll also have to boost the gpu_freq by editing the config.txt file once again. <\/p>\n\n\n\n
<\/div>\n\n\n\nWe\u2019ll set the arm_freq to 2147 and gpu_freq to 750 by changing the following settings:<\/p>\n\n\n\n
<\/div>\n\n\n\nover_voltage=6\narm_freq=2147\ngpu_freq=750<\/code><\/pre>\n\n\n\n<\/div>\n\n\n\nThe gpu_freq command will set core_freq, h264_freq, isp_freq, v3d_freq and hevc_freq all together which drives the L2 cache and memory bus for higher performance. A value of 750 is the highest value we\u2019ve gotten after rigorous testing.<\/p>\n\n\n\n
<\/div>\n\n\n\n- Save the file and exit Nano by CTRL+O and CTRL+X. Reboot your Pi 4 Now and you should see your device running at 2.147GHz!<\/li><\/ul>\n\n\n\n<\/div>\n\n\n\n
sudo reboot\nwatch -n 1 vcgencmd measure_clock arm<\/code><\/pre>\n\n\n\n<\/div>\n\n\n\nNOTE:<\/strong> Some Raspberry Pi 4 boards have failed to boot at this speed or slowed down due to overheating\/under-voltage. It\u2019s unlikely for you to run your Pi 4 board at this max speed in the long run, hence we recommend you to settle for arm_freq=2000 \/ stop at step 5. Do also be reminded to monitor your CPU temperatures, as overheating can cause irreparable damage!<\/p>\n\n\n\n<\/div>\n\n\n\n
\n\n\n\nSummary<\/strong><\/h2>\n\n\n\n<\/div>\n\n\n\nThat\u2019s all for today\u2019s tutorial on how you can easily overclock your Raspberry Pi 4. Overclocking your Pi 4 is a rather straightforward way to get extra performance from your CPU, but you should understand the risks and limits of overclocking – it’s definitely safe when done in a controlled manner. Always check the settings that you are about to change before affecting them to avoid voiding your warranty.<\/p>\n\n\n\n

Warranty and Risks<\/strong><\/h3>\n\n\n\n<\/div>\n\n\n\nIn most cases, overclocking is safe and will not void your warranty if done so in an appropriate manner<\/strong>. However, you should still be aware that there are several settings that will void the warranty by flipping a hardware switch inside your Pi:<\/p>\n\n\n\n- over_voltage greater than 6<\/li>
- force_turbo=1<\/li>
- temp_limit greater than 85<\/li><\/ul>\n\n\n\n<\/div>\n\n\n\n
There will always be a risk of your Raspberry Pi 4 overheating while being overclocked. This tutorial will teach you the safest method, but please be aware of and accept the risks that you will undertake by continuing!<\/p>\n\n\n\n
<\/div>\n\n\n\n
\n\n\n\n<\/div>\n\n\n\nStep 1: Prepare the Hardware<\/strong><\/h3>\n\n\n\n<\/div>\n\n\n\nBefore we get started, let\u2019s first go through what you\u2019ll need for this tutorial. Apart from your R<\/a>asp<\/a>berry Pi 4<\/a>, you\u2019ll need:<\/p>\n\n\n\n- A Raspberry Pi 4 Cooling Solution – Heatsink + Fan recommended<\/li>
- SD Card with Raspberry Pi OS Installed<\/li>
- A Reliable Power Supply<\/a> (official version is highly recommended) to ensure your Pi is not being starved of power<\/li><\/ul>\n\n\n\n<\/div>\n\n\n\n
Recommended Cooling Solution: <\/strong>Black Warrior ICE Tower CPU Cooling Fan<\/strong><\/a><\/h3>\n\n\n\n<\/div>\n\n\n\nUndoubtedly the biggest issue with the Raspberry Pi 4 is thermal issues and throttling. With the Pi 4 capable of reaching insane temperatures (even beyond 85\u00b0C) without overclocking, you\u2019ll definitely need a cooling solution in place if you want to overclock it!<\/p>\n\n\n\n
Black Warrior ICE Tower CPU Cooling Fan for Raspberry Pi<\/em><\/figcaption><\/figure><\/div>\n\n\n\nOne of the hot favourites here at Seeed is the Black Warrior ICE Tower CPU Cooling Fan for Raspberry Pi. It\u2019s capable of reducing temperatures from 80\u2103 to 40\u2103 and is designed by 52PI, a world-leading Raspberry Pi accessories manufacturer. To achieve such a level of cooling, this cooling kit includes a 5mm copper tube, multi-layered heat sinks, and a fan with 7 blades.<\/p>\n\n\n\n
<\/div>\n\n\n\nIf you\u2019re looking for a cooling solution that\u2019s more discrete, you can check out our list of Raspberry Pi cooling cases<\/a> and heat sinks!<\/a><\/p>\n\n\n\n<\/div>\n\n\n\nStep 2: Update your Raspberry Pi 4 Firmware<\/strong><\/h3>\n\n\n\n<\/div>\n\n\n\nFor the latest overclocking capabilities on the Pi 4, always update it to the latest version. This will give you the latest performance and reliability optimisations offered, which will improve your ability to reach higher clock speeds!<\/p>\n\n\n\n
<\/div>\n\n\n\nHere\u2019s how you can update your Pi 4 to the latest firmware:<\/p>\n\n\n\n
<\/div>\n\n\n\n- Open the terminal on your Raspberry Pi and enter the following code:<\/li><\/ol>\n\n\n\n<\/div>\n\n\n\n
sudo apt update\n\nsudo apt full-upgrade<\/code><\/pre>\n\n\n\n<\/div>\n\n\n\nSource: Cytron<\/a><\/em><\/figcaption><\/figure><\/div>\n\n\n\n2. Afterwards, reboot the system for the update to be applied!<\/p>\n\n\n\n
<\/div>\n\n\n\nsudo reboot<\/code><\/pre>\n\n\n\n<\/div>\n\n\n\nStep 3: Check the Default Speed of CPU<\/strong><\/h3>\n\n\n\n<\/div>\n\n\n\nThe next step before you overclock your Pi 4 is to check your CPU base speed. It is good to check the default clock speed to see the changeable value, which can be done by opening the command line and entering the following:<\/p>\n\n\n\n
<\/div>\n\n\n\nLscpu<\/code><\/pre>\n\n\n\n<\/div>\n\n\n\nor<\/p>\n\n\n\n
<\/div>\n\n\n\ncat \/sys\/devices\/system\/cpu\/cpu0\/cpufreq\/scaling_cur_freq<\/code><\/pre>\n\n\n\n<\/div>\n\n\n\nSource: Cytron<\/a><\/em><\/figcaption><\/figure><\/div>\n\n\n\n<\/div>\n\n\n\nThis indicates that my Pi 4 CPU base speed is 600MHz, the speed requested by the kernel!<\/p>\n\n\n\n
<\/div>\n\n\n\nStep 4: Let\u2019s start overclocking!<\/strong><\/h3>\n\n\n\n<\/div>\n\n\n\nTo overclock your Pi 4, we\u2019ll mainly be tinkering with the config.txt file<\/strong> under core configuration settings. Follow the instructions below carefully to avoid any errors.<\/p>\n\n\n\n<\/div>\n\n\n\n- Open your terminal window and enter the following code:<\/li><\/ul>\n\n\n\n<\/div>\n\n\n\n
sudo nano \/boot\/config.txt<\/code><\/pre>\n\n\n\n<\/div>\n\n\n\n<\/div>\n\n\n\n- Scroll down to the section marked:<\/li><\/ul>\n\n\n\n<\/div>\n\n\n\n
#uncomment to overclock the arm. 700 MHz is the default.\n#arm_freq=800<\/code><\/pre>\n\n\n\n<\/div>\n\n\n\n- Change the config settings to:<\/li><\/ul>\n\n\n\n<\/div>\n\n\n\n
#uncomment to overclock the arm. 700 MHz is the default.\nover_voltage=2\narm_freq=1750<\/code><\/pre>\n\n\n\n<\/div>\n\n\n\n- Save the file with CTRL+O (press RETURN) and use CTRL+X to exit. Now, restart your Raspberry Pi:<\/li><\/ul>\n\n\n\n<\/div>\n\n\n\n
sudo reboot<\/code><\/pre>\n\n\n\n<\/div>\n\n\n\n- Once your Raspberry Pi boots up again, use the vcgencmd command to check your new, faster clock speed:<\/li><\/ul>\n\n\n\n<\/div>\n\n\n\n
watch -n 1 vcgencmd measure_clock arm<\/code><\/pre>\n\n\n\n<\/div>\n\n\n\nThis command will monitor your real-time speed. Browse a few web pages on a few tabs and watch your CPU head on up to 1.75GHz!<\/p>\n\n\n\n
<\/div>\n\n\n\nStep 5: Overclocking your Pi 4 to even higher clock speed (2GHz)!<\/strong><\/h3>\n\n\n\n<\/div>\n\n\n\nIf you think overclocking it to around 1.75GHz is impressive, let\u2019s take things up a notch, by cranking your Pi 4 CPU to 2.0GHz.<\/p>\n\n\n\n
<\/div>\n\n\n\nWe will need to increase over_voltage to adjust the core CPU\/GPU voltage to accommodate the higher clock speed. We will be cranking the over_voltage value up to 6, which is the highest without voiding the warranty<\/strong>.<\/p>\n\n\n\n<\/div>\n\n\n\n- Edit the config.txt file with the following settings:<\/li><\/ul>\n\n\n\n<\/div>\n\n\n\n
over_voltage=6\narm_freq=2000<\/code><\/pre>\n\n\n\n<\/div>\n\n\n\n- Save the file and exit Nano by CTRL+O and CTRL+X. Reboot your Raspberry Pi 4 and run:<\/li><\/ul>\n\n\n\n<\/div>\n\n\n\n
sudo reboot\nwatch -n 1 vcgencmd measure_clock arm<\/code><\/pre>\n\n\n\n<\/div>\n\n\n\nSimilar to before, you’ll now see the clock speed limit to appear as 2.0GHz!<\/p>\n\n\n\n
<\/div>\n\n\n\nStep 6: Overclocking your Pi 4 to the Max level!<\/strong><\/h3>\n\n\n\n<\/div>\n\n\n\nNow for the moment you\u2019ve been waiting for, overclocking your Pi 4 to 2.147GHz max clock speed! This time, we\u2019ll also have to boost the gpu_freq by editing the config.txt file once again. <\/p>\n\n\n\n
<\/div>\n\n\n\nWe\u2019ll set the arm_freq to 2147 and gpu_freq to 750 by changing the following settings:<\/p>\n\n\n\n
<\/div>\n\n\n\nover_voltage=6\narm_freq=2147\ngpu_freq=750<\/code><\/pre>\n\n\n\n<\/div>\n\n\n\nThe gpu_freq command will set core_freq, h264_freq, isp_freq, v3d_freq and hevc_freq all together which drives the L2 cache and memory bus for higher performance. A value of 750 is the highest value we\u2019ve gotten after rigorous testing.<\/p>\n\n\n\n
<\/div>\n\n\n\n- Save the file and exit Nano by CTRL+O and CTRL+X. Reboot your Pi 4 Now and you should see your device running at 2.147GHz!<\/li><\/ul>\n\n\n\n<\/div>\n\n\n\n
sudo reboot\nwatch -n 1 vcgencmd measure_clock arm<\/code><\/pre>\n\n\n\n<\/div>\n\n\n\nNOTE:<\/strong> Some Raspberry Pi 4 boards have failed to boot at this speed or slowed down due to overheating\/under-voltage. It\u2019s unlikely for you to run your Pi 4 board at this max speed in the long run, hence we recommend you to settle for arm_freq=2000 \/ stop at step 5. Do also be reminded to monitor your CPU temperatures, as overheating can cause irreparable damage!<\/p>\n\n\n\n<\/div>\n\n\n\n
\n\n\n\nSummary<\/strong><\/h2>\n\n\n\n<\/div>\n\n\n\nThat\u2019s all for today\u2019s tutorial on how you can easily overclock your Raspberry Pi 4. Overclocking your Pi 4 is a rather straightforward way to get extra performance from your CPU, but you should understand the risks and limits of overclocking – it’s definitely safe when done in a controlled manner. Always check the settings that you are about to change before affecting them to avoid voiding your warranty.<\/p>\n\n\n\n

In most cases, overclocking is safe and will not void your warranty if done so in an appropriate manner<\/strong>. However, you should still be aware that there are several settings that will void the warranty by flipping a hardware switch inside your Pi:<\/p>\n\n\n\n There will always be a risk of your Raspberry Pi 4 overheating while being overclocked. This tutorial will teach you the safest method, but please be aware of and accept the risks that you will undertake by continuing!<\/p>\n\n\n\n Before we get started, let\u2019s first go through what you\u2019ll need for this tutorial. Apart from your R<\/a>asp<\/a>berry Pi 4<\/a>, you\u2019ll need:<\/p>\n\n\n\n Undoubtedly the biggest issue with the Raspberry Pi 4 is thermal issues and throttling. With the Pi 4 capable of reaching insane temperatures (even beyond 85\u00b0C) without overclocking, you\u2019ll definitely need a cooling solution in place if you want to overclock it!<\/p>\n\n\n\n One of the hot favourites here at Seeed is the Black Warrior ICE Tower CPU Cooling Fan for Raspberry Pi. It\u2019s capable of reducing temperatures from 80\u2103 to 40\u2103 and is designed by 52PI, a world-leading Raspberry Pi accessories manufacturer. To achieve such a level of cooling, this cooling kit includes a 5mm copper tube, multi-layered heat sinks, and a fan with 7 blades.<\/p>\n\n\n\n If you\u2019re looking for a cooling solution that\u2019s more discrete, you can check out our list of Raspberry Pi cooling cases<\/a> and heat sinks!<\/a><\/p>\n\n\n\n For the latest overclocking capabilities on the Pi 4, always update it to the latest version. This will give you the latest performance and reliability optimisations offered, which will improve your ability to reach higher clock speeds!<\/p>\n\n\n\n Here\u2019s how you can update your Pi 4 to the latest firmware:<\/p>\n\n\n\n 2. Afterwards, reboot the system for the update to be applied!<\/p>\n\n\n\n The next step before you overclock your Pi 4 is to check your CPU base speed. It is good to check the default clock speed to see the changeable value, which can be done by opening the command line and entering the following:<\/p>\n\n\n\n or<\/p>\n\n\n\n This indicates that my Pi 4 CPU base speed is 600MHz, the speed requested by the kernel!<\/p>\n\n\n\n To overclock your Pi 4, we\u2019ll mainly be tinkering with the config.txt file<\/strong> under core configuration settings. Follow the instructions below carefully to avoid any errors.<\/p>\n\n\n\n This command will monitor your real-time speed. Browse a few web pages on a few tabs and watch your CPU head on up to 1.75GHz!<\/p>\n\n\n\n If you think overclocking it to around 1.75GHz is impressive, let\u2019s take things up a notch, by cranking your Pi 4 CPU to 2.0GHz.<\/p>\n\n\n\n We will need to increase over_voltage to adjust the core CPU\/GPU voltage to accommodate the higher clock speed. We will be cranking the over_voltage value up to 6, which is the highest without voiding the warranty<\/strong>.<\/p>\n\n\n\n Similar to before, you’ll now see the clock speed limit to appear as 2.0GHz!<\/p>\n\n\n\n Now for the moment you\u2019ve been waiting for, overclocking your Pi 4 to 2.147GHz max clock speed! This time, we\u2019ll also have to boost the gpu_freq by editing the config.txt file once again. <\/p>\n\n\n\n We\u2019ll set the arm_freq to 2147 and gpu_freq to 750 by changing the following settings:<\/p>\n\n\n\n The gpu_freq command will set core_freq, h264_freq, isp_freq, v3d_freq and hevc_freq all together which drives the L2 cache and memory bus for higher performance. A value of 750 is the highest value we\u2019ve gotten after rigorous testing.<\/p>\n\n\n\n NOTE:<\/strong> Some Raspberry Pi 4 boards have failed to boot at this speed or slowed down due to overheating\/under-voltage. It\u2019s unlikely for you to run your Pi 4 board at this max speed in the long run, hence we recommend you to settle for arm_freq=2000 \/ stop at step 5. Do also be reminded to monitor your CPU temperatures, as overheating can cause irreparable damage!<\/p>\n\n\n\n That\u2019s all for today\u2019s tutorial on how you can easily overclock your Raspberry Pi 4. Overclocking your Pi 4 is a rather straightforward way to get extra performance from your CPU, but you should understand the risks and limits of overclocking – it’s definitely safe when done in a controlled manner. Always check the settings that you are about to change before affecting them to avoid voiding your warranty.<\/p>\n\n\n\n Thanks for reading! PS. Here is a list of warning icons<\/a> that may appear on the screen while you are attempting to overclock your Raspberry Pi. Always check if warnings appear or if you have any doubts!<\/p>\n\n\n\n Keen to learn more?
