Overclocking involves changing the default frequency of one of your computer’s components such as the CPU or GPU.

You can overclock your system’s elements in order to achieve the best possible performance and if you really want to perform overclocking it’s recommended that you also test your system’s GPU and CPU before or after you install a piece of overclocking software just to make sure that things are going smoothly.

Overclocking is a complex process that can improve your system’s performance, but it can also lead to overheating issues and permanently damage your CPU or GPU, that’s why it’s essential to use a tool to test overclocking.

Here are five of the best program for testing overclocking to keep your system safe and sound.

As an example, the products listed here are considered the best software to test overclocked GPUs at 1080p.
