M321R8GA0BB0-CQKMS Samsung 64GB DDR5 Dual Rank Memory

M321R8GA0BB0-CQKMS Overview

The Samsung is a 64GB DDR5 ECC registered memory module engineered for modern enterprise servers and data center workloads. Operating at 4800MHz with CL40 latency, it provides strong memory bandwidth for high-demand applications such as virtualization, cloud services, AI/ML, and large-scale data analytics. Its dual-rank (2Rx8) design offers a balance of density and performance, ensuring efficient throughput in multi-DIMM configurations. ECC functionality enhances system reliability by detecting and correcting memory errors automatically, which is critical for mission-critical workloads. As an RDIMM, it leverages a register buffer to stabilize memory signaling, supporting larger capacities and high module counts within a server.
