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.
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 . Download MATS rar
After the test, the tool generates a report.txt file. Look for "Write Errors" or "Read Errors" assigned to specific memory banks (A, B, C, etc.). Finding the "MATS.rar" Download
NVIDIA does not officially distribute MATS to the public; it is a "leaked" tool. If testing a card with no display output,
(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
Most versions are hosted on community repair forums like Repair.Wiki or specialized hardware subreddits like r/GPURepair . Command Execution: To run a basic memory test of 20MB:
You must create a bootable USB using a tool like Rufus or Etcher and a MATS/MODS disk image (.img).
