M393A2K43CB2-CTD Samsung 1x16GB DDR4 RDIMM ECC RAM

High-Density DDR4 RDIMM Server Memory Upgrade featuring ECC Registered stability with the M393A2K43CB2-CTD

The M393A2K43CB2-CTD is a 16GB DDR4 ECC Registered RDIMM designed to expand memory capacity in enterprise server platforms where predictable latency and fault containment are required. In dual-socket x86 environments running Intel Xeon Scalable or AMD EPYC DDR4 generations, this module supports higher population counts by using registered buffering to maintain signal integrity across multi-DIMM channels.

Built as a 288-pin, dual-rank x8 RDIMM with a 72-bit ECC data path, the M393A2K43CB2-CTD operates at 2666 MT/s (PC4-21300R) with 1.2V power and CL19 timings, enabling balanced bandwidth per channel for virtualization hosts and database nodes. While not a PCIe device, the M393A2K43CB2-CTD directly influences PCIe expansion and storage efficiency by reducing paging and IO amplification, helping CPU cores sustain throughput to NVMe and RAID storage stacks under consolidation and general compute workloads.

Why Choose the M393A2K43CB2-CTD?

The M393A2K43CB2-CTD delivers a practical density-to-stability profile for DDR4 RDIMM platforms where uptime is tied to memory correctness and platform scalability. ECC protection with registered architecture supports reliable operation in dense configurations, making the M393A2K43CB2-CTD a logical building block for incremental upgrades, cluster standardization, and predictable node-to-node performance.

Samsung engineers this class of RDIMM for consistent electrical margins, controlled thermals, and data center compatibility. The low-profile form factor supports constrained airflow designs, while enterprise-grade validation aligns the module with modern server qualification requirements and long-term serviceability expectations.

Key Applications:

• Virtualization and VM consolidation
• Database and transactional processing
• General compute and application servers
• Capacity upgrades for DDR4 RDIMM platforms
