However, none of these are accepted by NVIDIA for official RMA. For warranty claims, Mods is the gold standard.
Older leaked versions of MODS will not recognize newer GPU architectures (e.g., Ada Lovelace RTX 40-series or Blackwell RTX 50-series). 3. High Learning Curve

MATS is a specific sub-module embedded within the MODS directory. Its sole purpose is to test the . MATS writes specific bit patterns into every single memory address across all VRAM modules and reads them back. If the data read does not match the data written, MATS logs a write/read error and identifies the exact memory channel and chip that failed. Operating System Requirements: Why Windows Won't Work
If your goal is not hardware repair but performance analysis (i.e., finding why a game stutters or a CUDA kernel is slow), NVIDIA provides the suite. This is publicly available and legal to download via the NVIDIA Developer Program . However, none of these are accepted by NVIDIA
Understanding NVIDIA Modular Diagnostic Software (MODS): What It Is and How to Get It
Standard memory tests only tell you if your system RAM is failing. MATS pinpoint errors down to the exact bit, byte, and physical chip location on the GPU circuit board (PCB). This allows hardware repair technicians to desolder and replace only the specific faulty VRAM chip. 2. Low-Level Silicon Testing MATS writes specific bit patterns into every single
In conclusion, the NVIDIA Modular Diagnostic Software is a powerful tool that helps diagnose and troubleshoot issues with your NVIDIA graphics card. By downloading and using this software, you can improve graphics card performance, reduce system crashes, and stay up-to-date with the latest drivers. Follow the steps outlined in this article to download, install, and use the NVIDIA Modular Diagnostic Software, and unlock the full potential of your NVIDIA graphics card.
or specialized hardware forums often host scripts and bootable images (e.g., for RTX 30 and 40 series). Distribution
This module stresses the PCI Express interface to ensure all lanes operate at their rated speeds (e.g., PCIe 4.0 x16). It detects intermittent connectivity caused by cracked solder balls under the GPU core or physical damage to the gold contact pins. How to Set Up and Run NVIDIA MODS/MATS
To test memory, run the MATS module. A common command for a basic test is ./mats -e 20 is the amount of megabytes to test. Interpreting Results: After the test, the software generates a report.txt
