M321R4GA3EB0-CWM Samsung 1x32GB DDR5 ECC RAM

High-Performance DDR5 RDIMM ECC Server Memory enabling scalable bandwidth with the M321R4GA3EB0-CWM

The M321R4GA3EB0-CWM is a Samsung 32GB DDR5 Registered DIMM engineered for modern dual-socket server platforms that require predictable memory behavior under sustained load. By combining ECC with RDIMM buffering, M321R4GA3EB0-CWM supports stable operation as core counts increase and memory channels are fully populated, aligning with current-generation CPU architectures that depend on high memory parallelism for throughput.

Operating at 5600MT/s (PC5-44800R) on a 288-pin DDR5 interface, M321R4GA3EB0-CWM increases per-channel bandwidth to reduce CPU stall time in virtualization hosts, analytics nodes, and dense enterprise compute. The 72-bit data path provides continuous error detection and correction for uptime-focused environments, while the JEDEC server profile ensures consistent interoperability without XMP/EXPO dependencies. In systems that scale PCIe Gen5 expansion and NVMe storage, the balanced memory bandwidth of M321R4GA3EB0-CWM helps prevent memory bottlenecks that can limit I/O-driven workloads.

Why Choose the M321R4GA3EB0-CWM?

The M321R4GA3EB0-CWM is selected to optimize density-to-performance in standardized server builds where reliability, deterministic timings, and high DIMM population are mandatory. M321R4GA3EB0-CWM enables straightforward scaling across clusters by maintaining a consistent 32GB building block, supporting capacity planning for private cloud growth, and minimizing operational risk through ECC-protected, registered architecture.

Samsung designs server memory with a focus on signal integrity, long-life operating margins, and validation against enterprise platform requirements. This approach supports data centre standards for efficiency and maintainability, including low-voltage operation at 1.1V for controlled power and thermal envelopes.

Key Applications:

• Server virtualization and private cloud nodes
• In-memory databases
• Analytics and data processing
• General enterprise compute with high DIMM population
