How I overclocked my Odroid N2+?

I’ll walk you through the steps I took to overclock my Odroid N2+ from 2.2 GHz to 2.4 GHz while maintaining stability and acceptable temperatures.

Step 1: Research and Preparation

Before I began overclocking, I spent a considerable amount of time researching the process and gathering information from the Odroid community. I found helpful resources on the Odroid forums, where experienced users shared their insights and overclocking experiences. I also made sure to have the necessary tools and equipment, such as thermal paste, heatsinks, and a cooling fan.

Step 2: Backup Your System

Before making any changes to your Odroid N2+, it’s essential to create a backup of your current system in case something goes wrong. I used a backup tool available on my preferred Linux distribution to create a system image, ensuring that I had a safety net in place.

Step 3: Update the Boot Configuration

To adjust the CPU frequency, I modified the boot configuration file (boot.ini) on my Odroid N2+ as follows:

First, connect to your Odroid N2+ via SSH or access its terminal if you are using it with a display and keyboard.

Navigate to the directory containing the boot.ini file. For most Linux distributions, the file is located in the /boot directory. Enter the following command to navigate there:

cd /boot

Make a backup of the original boot.ini file using the following command:

sudo cp boot.ini boot.ini.bak

Open the boot.ini file using a text editor. For this example, I’ll use the nano text editor:

sudo nano boot.ini

Once you have the boot.ini file open, search for the lines containing “max_freq_a73” and “max_freq_a53.” These lines represent the maximum frequencies for the Cortex-A73 and Cortex-A53 cores, respectively. The default values are usually:


To increase the CPU frequency, modify these values. For example, if you want to increase the Cortex-A73 core frequency to 2.4 GHz and the Cortex-A53 core frequency to 2.1 GHz, change the values to:


Save the changes and exit the text editor. If you’re using nano, press Ctrl + X, then press Y to confirm the changes, and finally, press Enter to exit.

Reboot your Odroid N2+ for the changes to take effect:

sudo reboot

After the Odroid N2+ reboots, it will apply the new CPU frequencies you specified in the boot.ini file.

Step 4: Monitor System Stability and Temperatures

After adjusting the CPU frequencies, I saved the boot.ini file and rebooted my Odroid N2+. I then closely monitored the system stability and temperatures, using tools like “htop” to check CPU usage and the built-in temperature sensor to monitor temperatures.

Step 5: Stress Testing

To ensure my new settings were stable, I performed stress tests using tools like “stress-ng” to simulate high CPU loads. I monitored the system during the tests, checking for any signs of instability, such as crashes or excessive heat generation.

Step 6: Fine-tuning and Cooling

During the overclocking process, I had to experiment with different frequency increments and voltage adjustments to find the perfect balance between performance and stability. I also made sure to use an adequate cooling solution (heatsinks and a cooling fan) to prevent overheating and maintain acceptable temperatures.

Once I achieved stable performance at 2.4 GHz with manageable temperatures, I was satisfied with the overclocking results. Remember that each device may have slightly different results due to variations in manufacturing, so it’s essential to be patient and cautious during the overclocking process.

That’s a brief overview of the steps I took to overclock my Odroid N2+ from 2.2 GHz to 2.4 GHz. I hope you find this information helpful, and good luck with your overclocking adventures!
