M393A1K43DB2-CWE Samsung 1x8GB DDR4 RDIMM ECC RAM

High-Performance DDR4 RDIMM Memory Expansion featuring ECC Registered stability with the M393A1K43DB2-CWE

The M393A1K43DB2-CWE is a Samsung 8GB DDR4-3200 ECC Registered RDIMM designed for predictable behavior in enterprise server platforms where capacity planning, uptime, and serviceability are prioritized. As a 288-pin DIMM built for DDR4 RDIMM architectures, the M393A1K43DB2-CWE supports fault-tolerant memory expansion with ECC protection and registered signal buffering to help maintain integrity under sustained multi-core CPU load.

Optimized for current and legacy DDR4 platforms, the M393A1K43DB2-CWE aligns with PCIe-based server designs by ensuring the CPU memory subsystem remains stable as I/O, storage, and network traffic scale. Its 72-bit data path and single-rank x8 organization provide a balanced profile for density-constrained nodes, enabling right-sized per-slot capacity for light virtualization, infrastructure services, and dedicated appliance roles. The low-profile form factor further supports dense chassis layouts where airflow and mechanical clearance are critical to reliable operation.

Why Choose the M393A1K43DB2-CWE?

The M393A1K43DB2-CWE is selected when enterprise teams need controlled, incremental DDR4 capacity growth without changing the server’s memory architecture or compromising reliability. With ECC Registered design, it supports consistent performance per watt and predictable scaling in mixed workload environments, making it suitable for standardized rollouts across fleets where maintenance windows and qualification cycles are tightly managed.

Samsung engineers this RDIMM class for datacenter duty cycles, focusing on signal integrity, compatibility with mainstream DDR4 memory controllers, and production consistency that supports long-lived server configurations and structured lifecycle management.

Key Applications:

• ECC capacity expansion for DDR4 RDIMM servers
• Light virtualization and VDI pools
• Infrastructure services and directory servers
• Edge and branch office compute nodes
• Appliance-style platforms and legacy refreshes
