Edited by Sanam Nayab • By Mehwish Javed • Updated on November 24, 2022

Are you facing any problem related to your PC? Sometimes you may experience system slowdown, functions not working as expected, and unexpected shutdown because you did not check your PC before using them. It can happen if you have not tested your CPU before throwing it into the loads of intensive tasks. It can also cause permanent damage if you ignore these problems.

What is Stress Testing?

Stress testing is done for frequent computer hardware problems that are sometimes torture for people. To monitor your computer performance, you must conduct stress testing for your CPU and overall computer health. This type of performance testing validates the highest processing limits of your computer devices or networks induced with the extreme load.

It checks the system or network under the immense load, and whether it can recover while returning to normal. To certify that there are no hidden glitches, the most important thing before buying or building your PC is to stress test it for at least 6 to 7 hours to know that it is entirely stable.


Why is CPU Stress testing important?

Let us discuss here some of the reasons why CPU Stress Testing is important.

  • Performance Issues In Old Computers

Suppose your old computers are not working well and you face problems like immediate shut down, slowdown of computers performance, etc. In that case, you have to perform Stress Testing as it will help you find out the reason behind the issue and how to resolve it before the complete breakdown of computer.

  • Over Clocking

Suppose you use your computer daily for office work, gaming, or anything else that requires high performance by CPU. In that case, you can consider Over Clocking, with which you can run your PCs at much high speed than initially intended. The stress test will help you to check if performance has increased or not.

  • Computers Maximum Performance

Sometimes you do not get performance as mentioned or promised by salesperson. The computer is a machine with many components to effect performance and stability. To judge realistic performance, you have to perform Stress Test.

Different types of Stress Testing

Five types of stress testing ( Distributed, Application, Transactional, Systematic, and Exploratory) could be used depending on the type of testing you want to perform, like Stress Testing for your PCs, RAM, CPU, and GPU.

Your focus should be on the following points while testing stress on computers

  • CPU Stress Testing, performed to check the CPU performance after running it at full speed completely up to the maximum level.
  • GPU Stress Testing, executed to check its limit by utilizing its full processing power.
  • RAM Stress Testing, performed to examine how it behaves at increased voltage and temperature.
