Used GPU Verification & Stress Test

This laboratory-grade tool identifies if a used graphics card is genuine and stable before you finalize a purchase. It performs a high-intensity stress loop using WebGPU to push the video memory (VRAM) and silicon to its physical limits. Sellers on local marketplaces sometimes "flash" a fake BIOS onto cheap, older cards to trick your computer into displaying a more expensive model name. This test cross-references the physical hardware ID against manufacturer databases to catch these scams instantly.

If the results show a "BIOS Mismatch," the card is a fake. During the test, look for graphical artifacts such as green dots, flickering lines, or sudden browser crashes—these are signs of permanent hardware damage from mining or overheating. If the FPS stability score drops significantly during the ten-minute loop, the card's cooling system is likely failing, and you should avoid the purchase to prevent future system failures.
