Video Memory Stress Test (VMT) is a free and open-source graphics card stability testing tool for Windows. It allows users to perform a comprehensive test of their graphics card’s memory and check for any potential issues.

The program is designed to simulate real-world scenarios by running a series of complex graphics tests that push the limits of the graphics card’s memory. The tests include rendering large textures, complex 3D scenes, and more.

VMT supports multiple graphics APIs, including DirectX, OpenGL, and Vulkan. Users can customize the test parameters and set the duration of the test to suit their needs.

During the test, VMT will report any errors or warnings that occur, allowing users to identify potential issues with their graphics card’s memory. The program also provides detailed information about the graphics card, including the GPU model, clock speed, and temperature.

Overall, VMT is a powerful and useful tool for anyone looking to test the stability of their graphics card’s memory.

How to start Video Memory Stress Test

  • Download and install the software: First, you need to download the latest version of the Video Memory Stress Test from the developer’s website. Once the download is complete, run the setup file and install the software.
  • Open Video Memory Stress Test: After installation, open the software. You will see a simple user interface with several options.
  • Select the graphics card: Choose the graphics card that you want to test. If you have multiple graphics cards, you can select the one you want to test from the drop-down menu.
  • Set the test duration: Next, set the duration of the test. The default test duration is set to 15 minutes, but you can increase or decrease the test duration as per your requirements.
  • Start the test: Once you have configured the settings, click on the “Start Test” button to begin the test. The software will start to stress test the graphics card and will show the progress of the test.
  • Monitor the test: During the test, you can monitor the performance of your graphics card, including the GPU temperature, clock speed, and fan speed. You can also view the memory usage and the test results in real-time.
  • Analyze the results: After the test is complete, the software will display the test results. You can analyze the results and determine if your graphics card is functioning correctly or not.
  • Save the results: If you want to save the results of the test, you can export the test results to a CSV file.

Note: It is important to note that stress testing your graphics card can cause it to overheat and can potentially damage your hardware. Therefore, it is recommended to monitor the temperature and ensure that your graphics card does not exceed its maximum temperature limit during the test.
