NVIDIA does not officially distribute MATS to the public; it is a "leaked" tool.

Common versions found online include 367.38.1 (for older cards like Pascal) and 400.184 or newer (for RTX/Turing and Ampere cards).

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 .
