Samsung 64GB DDR5 4800MHz PC5-38400 ECC RDIMM Server Memory Module

The Samsung M321R8GA0BB0-CQK is a 64 GB DDR5 ECC Registered DIMM that brings the latest memory technology to servers requiring high capacity and dependable operation. Designed for platforms that accept DDR5 RDIMM modules, it reaches a data rate of 4800 MHz (PC5-38400) and runs on the standard 1.1 V supply, allowing administrators to boost bandwidth without increasing power budgets.

This module uses a 2Rx4 organization and integrates EC8 (10×4) parity architecture to correct errors on the fly. The built-in register manages clock and command signals, which helps every rank stay synchronized even when the memory bus is fully loaded. Combined, these features protect critical workloads from data corruption while keeping performance consistent.

Servers that host virtualization clusters, in-memory databases, or data analytics platforms gain tangible benefits from the larger memory pool and faster throughput. By installing one or more of these modules, IT teams can raise the virtual machine density on a hypervisor host, shorten query times in a database node, or give high performance computing applications the room they need to run efficiently.

Compatibility is limited to motherboards that accept DDR5 ECC Registered DIMMs, so it fits naturally in new generation enterprise servers and some advanced workstations. For best results, pair it with identical modules when populating multiple channels, and confirm that the system firmware supports DDR5 RDIMM before installation.
