Overclocking is a process of increasing the clock speed of your CPU beyond its default speed. This results in better performance and faster processing. However, overclocking is not for everyone and can be risky if not done properly. In this article, we will guide you through the process of overclocking your CPU.

What is CPU Clock Speed?

The clock speed of a CPU determines how many calculations it can perform in a second. This is measured in gigahertz (GHz). The higher the clock speed, the faster the CPU can perform. However, increasing the clock speed beyond the recommended limit can cause instability and damage the CPU.

Things to Consider Before Overclocking

Before overclocking your CPU, you must consider several factors. Firstly, make sure your CPU is capable of being overclocked. Check the manufacturer’s website or manual to see if your CPU supports overclocking. Secondly, ensure that your cooling system is adequate to handle the increased heat generated by overclocking. Finally, understand that overclocking will void your CPU’s warranty.

How to Overclock Your CPU

1. Enter BIOS: Restart your computer and enter BIOS by pressing the designated key. This key varies depending on your motherboard, but it’s usually F2, F10, or Del. 2. Increase Clock Speed: Look for the CPU clock speed or multiplier option in BIOS. Increase it by a small amount, such as 0.1GHz or a single multiplier, and save the changes. 3. Stress Test: After saving the changes, run a stress test to check if your CPU can handle the new clock speed. Use software like Prime95 or AIDA64 to stress test your CPU. 4. Monitor Temperatures: During the stress test, monitor your CPU temperatures using software like CoreTemp or HWMonitor. If the temperature is too high, reduce the clock speed or increase the cooling system. 5. Repeat Steps 2-4: Repeat steps 2-4 until you find the highest stable clock speed for your CPU.


Overclocking your CPU can be a great way to increase performance, but it’s not without risks. Before attempting to overclock, make sure you understand the process and have adequate cooling. Follow the steps outlined in this article to safely overclock your CPU and enjoy better performance.
