: It is distributed strictly through the NVIDIA Partner Alliance portal to authorized repair centers, OEMs, and engineering partners.
Enterprise clients with active support contracts (such as NVIDIA AI Enterprise or vGPU software support) can access specialized diagnostic packages directly via their enterprise licensing portal.
To use the NVIDIA Modular Diagnostic Software, follow these steps:
Conducting granular read/write tests on individual memory modules to locate specific bit errors.
Once the test completes, MATS generates a log file, usually named report.txt or mats.txt . Opening this file reveals a breakdown of the VRAM configuration. download nvidia modular diagnostic software
Used for comprehensive testing of the GPU chip itself and general board functionality. A submodule specifically designed to diagnose VRAM (Video RAM)
When a graphics card begins to fail, diagnosing the exact root cause can be incredibly difficult. Standard Windows-based benchmarking utilities like FurMark or 3DMark are excellent for testing overall system stability, but they cannot pinpoint a specific faulty memory chip or a broken trace on a circuit board.
Can stress test the core, memory controllers, and PCIe interface.
NVIDIA Modular Diagnostic Software (MODS) is an originally designed for NVIDIA technicians and Original Equipment Manufacturers (OEMs) to validate hardware and troubleshoot critical failures . It is not a consumer product and is primarily used today by third-party repair specialists to diagnose complex GPU issues . Overview of MODS and MATS : It is distributed strictly through the NVIDIA

NVIDIA Modular Diagnostic Software (MODS) is an official, low-level hardware diagnostic suite designed by NVIDIA for testing GeForce, Quadro, and Tesla graphics processing units (GPUs). Unlike consumer software, MODS operates entirely outside of the standard Windows operating system environment, usually running via a bootable Linux distribution or a specialized DOS environment.
: NVIDIA does not host MODS or MATS on its public website for general consumers.
If you are dealing with a malfunctioning NVIDIA graphics card, you might have heard of a tool called NVIDIA Modular Diagnostic Software, commonly known as . This specialized software is one of the most powerful tools available for testing, diagnosing, and isolating hardware faults on NVIDIA GPUs. Once the test completes, MATS generates a log
Executables can infect your operating system, steal credentials, or encrypt files.
Since most users look for MODS/MATS to test for failing video memory, these public alternatives serve the same practical purpose safely:
If the card has output (but artifacts):
Malicious actors frequently bundle malware, trojans, or crypto-miners into files labeled as "NVIDIA MODS Download."
