How to Stress Test GPU | Step-by-Step Method

Share on:

Stress tests of GPU or any other computer parts are important for identifying the performance. We can know the breaking point and stable point of a PC by going through this test. By this, we can maintain our work on the PC. Both software and hardware can be gone through the stress test. After doing the test, we can avoid doing a hamper to our PC. But there are some risks to doing this. We should do the test safely by applying the accurate method. So, How to stress test GPU? Read through this.


What is a Stress Test

A stress test is a form of test which is done in a computer’s hardware and software to determine the stability of any computer system and also its infrastructure. It is also called torture testing. It is done by going beyond the capacity of the system and also many things are done beyond its breaking point. Also, the test can identify the accurate breaking points and how the system actually fails. It can confirm that the specifications of the system can be met. By doing this, you can be sure which hardware of your computer should be changed or not.

What Should Monitor During the Test

You need to monitor the system during the test. The GPU overclocking application can monitor your GPU continuously. In this, you need to monitor two things.

  • GPU temperature
  • GPU usage

During the test, the temperature can be increasing about 100 degrees Celsius and GPU usage can be hit to 100 percent. You have to monitor it and take the necessary steps to avoid any problems.

What Are the Tools to Use to Stress Test GPU

There are some tools that are used to stress test GPU. They are described below.


FURMARK is one of the best tools which can stress test your GPU. It can only be used in Windows PC.

This tool uses fur-rendering algorithms. It helps to measure the performance of graphics cards. It also measures the stability of overclocking. 

The tool can identify all the errors of your GPU effectively. It can push the machine at its highest without doing any harm to GPU or PC. It is a very user-friendly tool.


This GPUMEM TEST tool is used generally for stress testing Nvidia graphics cards. This card, it can measure accurate errors.


This OCCT tool can not only stress-test GPU but also CPU. It can monitor accurately every error. It can continuously show the voltage, temperature, power supply, the fan speed of your system.

4. UNIGINE Super position

It is one of the advanced stress testing tools. UNIGINE Superposition can measure all the lighting shading effects on GPU. It comes with an advanced VRS testing feature.

5. UNIGINE Heaven

UNIGINE Heaven is more advanced than Superposition. It is very pretty to look at. This benchmarking tool is really better than most of the tools. 

Steps to Perform Stress Test GPU

For avoiding all the damage like damaging the motherboard or CPU, you should follow the given steps carefully. The steps are

Step 1: Set Up the Overclock Choice

First, you need to set up the overclock choice. If you do not want to overclock, skip the part. You can check how to overclock the CPU.

Step 2: Close Running and Background Applications

Before stress testing, you have to close all the applications that are running on the PC or running in the background. You have to close all the media apps immediately. The apps can affect your stress test result. Also, your system may be crashed because of it.

Step 3: Launch Stress Test Application

You have to open the stress test application which is installed on your PC. Then start the operation. Your GPU usage will hit up to 100 percent and your temperature will be increased at the highest point.

Step 4: Start the Stress Test

Then you have to run the test for 30 minutes. If your PC has a cooling or overclocking problem, your PC test cannot be run after 30 minutes. If your PC passes the 30 minutes test, it should be cleared of all the media assumptions. After the failure of the test, you should turn off the clock, and turn up the fan. 

Step 5: Perform the 2nd Test

In the 2nd test, you will be testing the game scenario of GPU. You have to run the test for one hour at this stage. If your PC completes the test without any problem, then it should be cleared for any gaming scenario. Your PC monitor will play a vital role just in terms of viewing during the test.

Step 6: Perform Stability Test

The last stage of the test is the guaranteed stability test. In this, the test will run for a long time. If the PC passes the test without creating any damage, your GPU should be cleared from almost anything.

Frequently Asked Questions

Does stress test for prolonged time damage GPU?

Yes, if you repeat the stress test for a prolonged time there is a higher chance of GPU’s thermal can be affected.

Can a stress test break a PC?

No, the stress test is a safe test that you can do on your PC. If your system is newer and the CPU is not that old then while doing the stress test, whenever the CPU reaches its critical point, it will shutdown the computer. And if the CPU is old enough then it will end up by damaging your entire system.


You should work on your PC according to the stability of its hardware and software. The breaking point helps you to well aware of its weakness. The stress test of the GPU can confirm the specifications and performance of the GPU. Applying the accurate process, you can stress test your GPU without damaging the system. You can check VRAM, increase VRAM, and how you can increase virtual memory. After reading the whole article, now we hope that you know all about how to stress test GPU. To get a better idea about different types of monitors, we suggest you read this article named CRT vs LCD monior.
