Stress tests for CUDA and OpenCL compatible GPUs

Updated June 2024: Stop getting error messages and slow down your system with our optimization tool. Get it now at this link
  1. Download and install the repair tool here.
  2. Let it scan your computer.
  3. The tool will then repair your computer.

One of my colleagues posted a thread in a forum on MemtestG80 and MemtestCL. MemtestG80 and MemtestCL are software testers for testing software errors in GPU memory or logic for NVIDIA CUDA or OpenCL GPUs (from any manufacturer). This is good news for new GPU card owners because they can check the stability of their card, i.e. it detects software errors in GPU memory or logic for GPUs that support CUDA or OpenCL, which can often lead to random crashes – even BSODs.

This is a command line program, as you can see in the screenshot above. You will see on the image that it sends the test results to its developers at Stanford; but if you want to avoid it, you must use an additional flag as described above.

According to developer Imran Haque :

June 2024 Update:

You can now prevent PC problems by using this tool, such as protecting you against file loss and malware. Additionally it is a great way to optimize your computer for maximum performance. The program fixes common errors that might occur on Windows systems with ease - no need for hours of troubleshooting when you have the perfect solution at your fingertips:

  • Step 1 : Download PC Repair & Optimizer Tool (Windows 10, 8, 7, XP, Vista – Microsoft Gold Certified).
  • Step 2 : Click “Start Scan” to find Windows registry issues that could be causing PC problems.
  • Step 3 : Click “Repair All” to fix all issues.


It uses a variety of proven test models (some user-defined and others based on Memtest86) to verify the GPU’s memory and logic function. These are useful tools to ensure that some GPUs do not produce silent errors that can distort the results of a calculation without causing an open error.

Depending on the FAH search page, this test can be used for NVIDIA/ATI GPUs. To use this program, compatible drivers must be installed on your computer – for nVidia cards, you need 195 series or newer drivers and for ATI cards, version 9.12 or newer.

You must register on their website to download the application, or you can visit the Stanford website to download it from there.

As with any stress test, use it at your own risk as it can cause potential damage.

Expert Tip: This repair tool scans the repositories and replaces corrupt or missing files if none of these methods have worked. It works well in most cases where the problem is due to system corruption. This tool will also optimize your system to maximize performance. It can be downloaded by Clicking Here
