Samsung 32GB DDR5 4800MHz PC5-38400 ECC RDIMM 2Rx8 Dual Rank Memory Module

The Samsung M321R4GA3BB6-CQK is a 32 GB DDR5 ECC Registered RDIMM that brings high memory bandwidth and reliable operation to modern servers. Built for data centers and enterprise environments, it slips into a compatible motherboard to deliver the capacity and stability that demanding workloads expect.

Running at 4800 MHz (PC5-38400), the module gives servers ample throughput for virtualization hosts, real-time analytics, and large in-memory databases. The 2Rx8 dual rank layout helps the system access memory more efficiently, which can translate into smoother application performance when many virtual machines or containers share the same hardware.

Integrated error correcting code adds parity bits that detect and correct single-bit faults before they reach the operating system. A registered buffer steadies command and control signals, an advantage when you populate multiple DIMM slots in high-density configurations. Together, these features help minimize downtime and protect critical data.

The module follows the 288-pin DDR5 ECC RDIMM standard and operates at just 1.1 volts, easing power budgets in energy-conscious racks. It works with platforms that support DDR5 ECC RDIMM, including many systems built on 4th Gen Intel Xeon and AMD EPYC processors. Whether you are expanding an existing server or specifying memory for a new build, installation is straightforward—seat the module, secure it with the retention clips, and power the system back on.

Samsung’s extensive experience in memory manufacturing provides an additional layer of confidence for administrators rolling out large fleets. Consistent performance, proven compatibility, and integrated error correction make this DIMM a practical choice for environments where performance and reliability go hand in hand.
