I run MemTest86 a lot at work on customer's machines, and it's great for troubleshooting memory issues. My question is, how can I test that a GPU is starting to go?
I know of programs like 3DMark to push the graphics card to its limits, but what about with Video Memory? Is it worth testing? Is there a stress tool actually able to catch issues in the video card (memory), perhaps using CUDA/OpenCL?
Warning: This GPU stress test method may not be suitable for newer graphics cards. It is primarily designed for older hardware that have less than 1GB of VRAM .
GPU stress tests are generally designed to attempt to overheat the GPU. Depending on the particular test, this might or might not use the entire video memory or check its integrity at some point.
Video Memory stress Test is specifically designed for this purpose, and it's quite similar to MemTest86+. You can test the memory using DirectX, CUDA, or OpenGL.
The downloadable zip contains VMT (for Windows) and VMTCE (Clean Environment, bootable ISO). There's also a floppy version.
