Samsung 32GB DDR5 4800MHz PC5-38400 ECC RDIMM Memory Module

The Samsung M321R4GA0BB0-CQK is a 32 GB DDR5 ECC Registered DIMM designed for servers that need dependable memory with high throughput. It runs at 4800 MHz and follows the JEDEC PC5-38400 specification, giving administrators a straightforward upgrade path to the latest DDR5 bandwidth without sacrificing stability.

This module features a 1Rx4 organization based on a (4 G x 4) x 20 component layout, along with integrated error correction that uses an 8-bit parity scheme. The built-in register buffers clock, command, and control signals, which helps maintain signal integrity on multi-slot motherboards. A standard 288-pin footprint and a low 1.1 V operating voltage make it a direct fit for DDR5 server boards built around 4th Gen Intel Xeon or AMD EPYC processors.

In daily operation, the module supports demanding workloads such as large virtualization clusters, real-time analytics, and in-memory databases. Data center teams can rely on its ECC capability to detect and correct bit errors before they escalate, while development labs or research facilities benefit from the consistent performance required for parallel computing and simulation tasks.

Whether you are expanding a rackmount server to handle more virtual machines or building a new HPC node that cannot afford downtime, this Samsung DDR5 RDIMM delivers a blend of speed, capacity, and error resilience that keeps critical applications responsive.
