For bare-metal servers, you can install DCGM directly using package managers (e.g., apt or yum ) after adding the NVIDIA CUDA repository. sudo apt-get install datacenter-gpu-manager Use code with caution. For RHEL/CentOS: sudo yum install datacenter-gpu-manager Use code with caution. Utilizing the DCGM Diagnostic Tool
If tools like OCCT report explicit memory errors, the physical VRAM modules likely need replacement. If the card is under warranty, contact the manufacturer (ASUS, MSI, etc.) to initiate an RMA rather than attempting to flash factory diagnostic code yourself.
I can guide you toward the right version or suggest a safer software alternative.

Step-by-Step Deployment: Setting Up a Bootable MODS/MATS USB
Where can I download the NVIDIA Field Diagnostic software？ - Linux 19 Jun 2019 —
Older versions of MODS (used for Kepler, Maxwell, and early Pascal cards) run inside a pure DOS environment to ensure zero driver interference. For bare-metal servers, you can install DCGM directly
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
The tool most commonly boots into a miniature Linux distribution. For memory testing, the command is usually ./mats -n [index] -e [size_to_test] , where index is the GPU number. Documentation and Guides
: This flag dictates the size of the test. The number 20 tells MATS to test the first 20 Megabytes of every memory bank. For a comprehensive test on modern high-capacity cards, technicians use -e 500 or higher, though it takes significantly longer.
