M393A2K43DB3-CWE Samsung 1x16GB DDR4 RDIMM ECC RAM

Enterprise DDR4 RDIMM Memory Expansion featuring ECC Registered Reliability with the M393A2K43DB3-CWE

The M393A2K43DB3-CWE is a Samsung 16GB DDR4-3200 ECC Registered RDIMM engineered for mainstream and scale-out server CPU platforms that rely on DDR4 memory channels for predictable throughput. By using a registered DIMM design, the M393A2K43DB3-CWE supports higher-population memory configurations with improved signal integrity, enabling balanced capacity planning across multi-socket virtualization hosts and general-purpose compute nodes.

In modern architectures where CPU core counts, PCIe expansion, and storage IO (NVMe/SAS/SATA) compete for bandwidth, stable memory behavior is foundational. The dual-rank x8 organization and 72-bit ECC data path of the M393A2K43DB3-CWE help maintain data integrity under always-on service loads, while DDR4-3200 operation aligns well with platforms that need consistent memory bandwidth for VM density, caching tiers, and infrastructure services. Low 1.2V operating requirements also support power-aware data center design without sacrificing reliability.

Why Choose the M393A2K43DB3-CWE?

The M393A2K43DB3-CWE delivers an effective density-to-performance ratio for DDR4 servers that must scale memory capacity without destabilizing channel timing. As an ECC Registered module, the M393A2K43DB3-CWE is suited to controlled expansion plans, helping IT teams standardize DIMM populations across clusters while preserving enterprise reliability and service continuity.

Samsung memory is designed with a manufacturing focus on consistency, validation, and long-term availability for data center lifecycles. The M393A2K43DB3-CWE follows server-grade qualification practices to support interoperability with modern platform firmware, thermal envelopes, and operational standards expected in enterprise racks.

Key Applications:

• Virtualization hosts and VM consolidation
• General-purpose compute and application servers
• Infrastructure services (DNS, DHCP, directory services)
• Database middleware and caching layers
• Private cloud capacity expansion
