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.
It reports errors by channel (e.g., A0, B1), allowing technicians to know which chip to de-solder and replace.
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 Download MATS rar
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
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 . MATS specifically targets the Video RAM (VRAM) of
You must create a bootable USB using a tool like Rufus or Etcher and a MATS/MODS disk image (.img).
NVIDIA does not officially distribute MATS to the public; it is a "leaked" tool. After the test, the tool generates a report
The tool typically runs in a minimal Linux environment booted from a USB drive.
