M321RYGA0BB0-CQK Samsung 1x96GB DDR5 ECC RAM

High-Density DDR5 RDIMM Server Memory Expansion with the M321RYGA0BB0-CQK

The M321RYGA0BB0-CQK is a Samsung 96GB DDR5 RDIMM engineered to expand memory capacity in DDR5-capable rack servers while maintaining enterprise-grade signal integrity and error protection. As a registered, dual-rank x4 module with ECC on a 72-bit data path, it supports stable operation under high concurrency where memory reliability directly impacts node availability.

Designed for platforms leveraging DDR5 bandwidth, the M321RYGA0BB0-CQK operates at 4800 MT/s (PC5-38400R) with CL40-40-40-77 timings at 1.1V, aligning with modern server power and thermals targets. RDIMM buffering reduces electrical loading on the memory controller to enable higher population across channels, while the low-profile form factor improves mechanical clearance and airflow planning in dense 1U/2U chassis. This architecture is well matched to virtualization hosts, in-memory databases, and general-purpose compute nodes that need predictable latency behavior, scalable capacity per socket, and uncompromised ECC coverage.

Why Choose the M321RYGA0BB0-CQK?

The M321RYGA0BB0-CQK delivers a strong density-to-slot ratio, enabling meaningful capacity uplift without redesigning the server platform or compromising DIMM population rules. For enterprise deployments, its registered ECC design supports consistent performance at scale, helping standardize node configurations across clusters and simplifying lifecycle expansion as workload footprints grow.

Samsung server memory engineering focuses on validation depth, process consistency, and compatibility with current data center standards, supporting long service windows and predictable behavior in mixed workload environments where uptime and data integrity are non-negotiable.

Key Applications:

• DDR5 server memory expansion
• Virtualization and private cloud hosts
• In-memory databases and caching tiers
• General-purpose compute clusters
