How to Perform stress-test on CPU – Guide

A CPU stress test is a software program specifically designed to give your CPU incredibly difficult tasks. Gives the CPU so many of these difficult math problems that its full attention is taken up. The result final is a test of your CPU’s peak performance. Most real-world tasks, even those that push your CPU to 100% capacity, don’t run in this brutal, sustained manner.

You might wonder why anyone would want to torture a bad CPU this way, but it’s actually an important part of many aspects of computer development and maintenance. Stress testing is an important tool in your technology maintenance arsenal. Overclocking a PC can lead to instability, and stress testing is aimed at detecting problems before they occur in actual use. Stress tests check your PC’s stability, pushing it to the limit. When you finish reading this article, you can test your CPU.

How to Run the CPU stress test

How to stress test a pc

Prepare your computer for a stress test by closing all non-essential applications and checking the CPU temperature.

Choose and download a stress testing tool.

Run the stress test while monitoring your CPU temperature.

How to get ready for a computer stress test

Close all non-essential applications. Background and foreground processes can interfere with CPU stress testing. Closing these programs and processes is a great way to speed up up your computer.

Download and install AVG TuneUp to identify any programs that waste RAM and CPU resources. AVG TuneUp’s Sleep Mode technology puts these programs to sleep and stops all background activities, ensuring that your PC devotes all its resources to the CPU stress test.

Open AVG TuneUp, go to Speed ​​Up, and click Background Programs and Startup. Sleep Mode will detect unnecessary programs and temporarily disable them to ensure your test provides the most accurate results possible.

Monitor your CPU temperature: Do not let your CPU temperature exceed 90°C for prolonged periods.

What are the best tools for a CPU load test

Prime95

Prime95 is one of the most popular CPU stress testing tools out there. It uses the Mersenne prime technique, which makes uninterrupted use of the FPU (floating point unit) and entire resources of your processor, while also testing your various caches (L1, L2, L3). Here it is how to use Prime95 to perform a PC stress test:

Download Prime95. Choose the 64-bit Windows option, which is the basis for all newly built and purchased PCs. Only PCs made in the 2000s, or extremely simple machines from the early 2010s, run on 32-bit software.

Launch the tool and select Stress Test Only. Choose the Blend option, which tests all cores and caches. Then click OK.

At this point, the test will start. Your processor and all its cores will immediately reach 100% capacity, and your computer’s fans will kick in.

As with other stress testing tools, you should let it run for about an hour (or if you really want to know the maximum limits: a day).

AIDA64

With 25 years in the industry, AIDA is a huge set of tools for displaying and diagnosing your entire machine. It’s available as a premium product, but you can also download a free trial for a quick PC stress test. The AIDA64 System Stability Test simulates a realistic workload for your computer. Here it is how to launch it and run a CPU load test:

Download the AIDA64 test. Extract the files and double-click the AIDA64.exe file.

If you wish and we recommend that you do so, you can go through the individual categories and explore the inner workings of your PC. Try selecting Memory from the motherboard drop-down menu to learn more about your machine’s RAM.

In the Benchmark category, you can test your system and compare it to other PCs.

To start the computer stress test, click Tools and select System Stability Test. When ready, click Start.

During this test, you can easily go back to the main window of AIDA64 and go to Computer and Sensor. Here, you can watch the CPU temperature and see how fast your fans are spinning.

As long as the temperature stays below 90°C, you should be fine. Let it run for a few hours and see if your PC remains stable.
