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
You must create a bootable USB using a tool like Rufus or Etcher and a MATS/MODS disk image (.img).
Common versions found online include 367.38.1 (for older cards like Pascal) and 400.184 or newer (for RTX/Turing and Ampere cards). Download MATS rar
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 .
It reports errors by channel (e.g., A0, B1), allowing technicians to know which chip to de-solder and replace. While it supports a wide range of architectures
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 .
The tool typically runs in a minimal Linux environment booted from a USB drive. If testing a card with no display output,
MATS specifically targets the Video RAM (VRAM) of NVIDIA GPUs. When a graphics card shows artifacts, crashes under load, or fails to output a signal, MATS can pinpoint exactly which physical memory chip is failing.
