If you are looking for diagnostic software to check the health, temperature, and memory usage of your GPU, this is the standard tool.
There is no single "download NVIDIA modular diagnostic software" button on the public website. Instead:
When the test finishes, it generates a report.txt file.

MODS provides a level of diagnostic depth that standard software cannot replicate. By bypassing the Windows or standard Linux graphics stack, it eliminates software-driven variables, ensuring that any reported errors are purely physical hardware faults.
It moves beyond simple error reporting to "active health," meaning it can diagnose issues before they cause application failures.
Because MODS interacts with hardware at a foundational level, improper use can lead to permanent component damage or firmware corruption. Consequently, Nvidia does not distribute MODS as a public download for general consumers or gamers. Official Enterprise Distribution Channels If you are looking for diagnostic software to
To run the software, you typically need a 2GB+ USB drive and an imaging tool like Rufus to create a bootable environment.
If training status codes indicate errors (e.g., specific alphanumeric characters), it points directly to a particular memory chip.
To specifically test memory, technicians often run the MATS tool to identify faulty memory banks, especially on GDDR6X and GDDR7 cards. ./mods/mats -n 1 -v 3 Use code with caution.
