: A specialized module within MODS designed to identify specific faulty VRAM banks. It generates a text report (often report.txt ) that maps out which memory chip is failing, allowing a technician to replace only the defective component rather than the entire card. Usage and Installation
Here are some tips and tricks to get the most out of the NVIDIA Modular Diagnostic Software:
MODS is a powerful diagnostic suite used primarily by NVIDIA’s internal engineers and Authorized Board Partners (AIBs). Unlike simple benchmark tools, MODS interacts directly with the GPU hardware to identify specific points of failure.
MODS is a powerful diagnostic suite used to identify hardware-level faults in NVIDIA graphics cards. MODS (Modular Diagnostic Software): Tests the core GPU chip and general board functionality. MATS (Memory Automated Test System): download nvidia modular diagnostic software
Once booted, you do not need Linux experience. The interface is menu-driven.
In the example above, is throwing thousands of read/write errors. A technician knows instantly that the specific VRAM module corresponding to Bank B0 is faulty and must be desoldered and replaced using a BGA reballing station. Publicly Available Alternatives

NVIDIA Modular Diagnostic software is not public freeware. It is protected intellectual property. Searching for "NVIDIA Diagnostic download" on public forums or torrent sites poses a severe security risk, as bad actors often embed malware, keyloggers, or crypto-miners into fake diagnostic executables.
The most famous sub-program bundled within MODS. MATS is specifically designed to test the dedicated video memory (VRAM) of a graphics card. It identifies the exact memory module (or chip) that is throwing read/write errors. Key Features and Capabilities Unlike simple benchmark tools, MODS interacts directly with
MODS and MATS are powerful because they operate at a low level, often bypassing standard OS drivers to communicate directly with the hardware:
Instead of a monolithic diagnostic tool, NMDS offers a where users select only the diagnostic modules they need for their specific NVIDIA hardware (GPU, vGPU, DPU, Tegra, or NVSwitch).
This comprehensive guide covers everything you need to know about MODS, its companion tool MATS, and how professionals use them to diagnose complex GPU failures. What is NVIDIA Modular Diagnostic Software (MODS)?
