About the Samsung 512GB DDR5 LRDIMM
The Samsung 512GB DDR5 LRDIMM (M321R8GA7BB4-CWM) delivers exceptional performance at CAS Latency 40 with ultra-low 1.1V operating voltage—critical specifications for high-frequency trading platforms, real-time analytics, and in-memory databases requiring minimal latency overhead. This enterprise-grade module combines Samsung's 3DS stacking technology with registered clock drivers and integrated data buffers to reduce signal loading across dense server configurations.
Built for Intel Xeon Scalable processors (Sapphire Rapids and compatible platforms), this LRDIMM enables storage architects and AI infrastructure teams to maximize memory capacity without compromising system stability. The 8-rank design with on-die ECC protection and 72-bit data width ensures fault-tolerant operation across mission-critical workloads. Operating across the commercial temperature range (0°C to 85°C), the M321R8GA7BB4-CWM adheres to JEDEC DDR5 LRDIMM standards, guaranteeing compatibility and long-term supply consistency. Samsung's proven reliability in enterprise environments makes this module ideal for hyperscale data centers, high-performance computing clusters, and virtualization platforms demanding 512GB single-module capacity.
