Everything You Need To Know About CPU Stress Test

You have invested a huge amount to build a desktop or purchased a high-end laptop so that you can fulfill your gaming desires. Or, maybe you have recently upgraded your old machine to quench your video-editing desires. But, before you do that you would benefit from a CPU stress test. The test will tell you if the brain of your computer in all its entirety is capable of processing high-end applications or resource-intensive games. 

In this post, we’ll give you a basic overview of what is a CPU stress test, what are the things you should keep in mind when conducting one, and the tools you can use to conduct a CPU stress test. 

1. What is a CPU Stress Test?

A CPU stress test or CPU load test means running the CPU at its maximum efficiency for a specified period of time so as to check how stable it is. A CPU stress testing software uses a variety of methods to help reach the CPU its maximum capacity. For example, it will push the CPU to reach its maximum capacity for 1 hour and then it will analyze the CPU’s performance. 

When you conduct a test to stress your CPU, you essentially max its speed as well as temperature. Here all the cores of the chip will be utilized. 

2. Prerequisites Before Performing A CPU Load Test

Much before you perform a CPU stress test, it is important that you first make your PC and CPU ready for the same. First and foremost, close all the background apps which are resource-intensive and which you think will hamper the CPU load test. The same goes for any redundant processes on your Windows. 

  • Close all redundant background processes and applications which you think may interfere with your CPU stress test. This step would also help in increasing the speed and overall performance of your PC. For this first close all applications running on your computer. 
  • You can also fire up the Task Manager by pressing the ctrl + shift + esc key combination and then selecting app or background process and then pressing End Task from the bottom-right corner of the screen.

4. How To Conduct CPU Load test?

Tools like Prime95 are one of the best tools that can help you conduct computer stress tests such as CPU stress tests. Prime95 in particular takes into account the Mersenne prime number and can generate a heavy CPU workload. If you can afford to run the tool for 5-6 hours straight, you can get a pretty good indication that your CPU is not just in a good shape but is running great.

6. What Does It Mean When Your Computer Says That System Has Failed CPU Test?

At the outset, we’d like to mention that even if you get the above-mentioned error message, needn’t lose heart because most issues are resolvable – 

– Hardware Upgrade

Hardware just like any other thing is perishable and as we said, CPU issues may surface if you have an older CPU or power supply. You could start with easy stuff such as getting dust off your fan if it’s clogged. If need be, upgrade your fan or consider water-cooling. If you are someone who is into heavy gaming and overclocking computer resources, especially the CPU, and have scarce RAM, consider upgrading it and getting more RAM. 

– Are There Any Outdated Drivers

A failed stress test could also indicate that your PC or laptop has corrupt or outdated drivers. Outdated and corrupt drivers are anyways a plight and should be fixed immediately. And, in case you are planning to conduct any computer stress test such as a CPU load test, even much before doing that, consider updating drivers on your Windows PC

For the same, using driver updater software is probably the best way to identify outdated drivers and update them. Advanced Driver Updater is one of the best driver updating utilities which doesn’t just help in updating corrupt or outdated drivers but, helps you do the same in an error-free fashion here’s how – 

  • By identifying outdated and corrupt drivers. 
  • Letting you create a backup of drivers before updating them.
