If testing a card with no display output, use an integrated GPU or secondary card and specify the target index: ./mats -n 1 -e 50 .
You must create a bootable USB using a tool like Rufus or Etcher and a MATS/MODS disk image (.img).
(Memory Automated Test System) is a powerful, leaked internal diagnostic tool from NVIDIA used to identify faulty VRAM chips on graphics cards. It is often bundled with MODS (Modular Diagnostic Software), which performs broader GPU health checks. Core Functionality
Because these files come from unofficial third-party sources, always scan downloads for malware and ensure you are comfortable using command-line tools before proceeding.
NVIDIA does not officially distribute MATS to the public; it is a "leaked" tool.
The system must be booted in Legacy/CSM mode , as the tool often fails to run in UEFI mode. Command Execution: To run a basic memory test of 20MB: ./mats -e 20 .
While it supports a wide range of architectures (from the 900 series up to modern RTX 40 and 50 series), it is exclusive to NVIDIA hardware and does not work on AMD cards. How to Use MATS
