Targeted Server Upgrade

This 16 GB DDR4 3200 ECC registered DIMM is built for the Gigabyte MZ31-AR0 motherboard running AMD EPYC processors. IT administrators choose it when a single-module capacity increase is required for virtualization hosts, database nodes or high-density compute clusters.

Registered Signal Integrity

The 1Rx4 organization and on-module register reduce electrical load on the memory controller, allowing stable operation at 1.2 V across all populated slots. A standard 288-pin RDIMM key ensures correct seating in the server board without adapters or special tools.

Validated Module Only

The package contains the qualified memory stick; no cables, brackets or software licenses are included. Compatibility validation performed by the vendor aims to eliminate trial-and-error installation in mission-critical environments.
