M378A2K43DB1-CTD Samsung 1x16GB DDR4 UDIMM RAM

High-Performance DDR4 UDIMM Server/Workstation Memory Module featuring JEDEC 2666 MT/s efficiency with the M378A2K43DB1-CTD

The M378A2K43DB1-CTD is a 16GB DDR4 UDIMM engineered for server-adjacent and workstation platforms that implement unbuffered, non-ECC memory channels. In CPU-centric architectures where the integrated memory controller is tuned for UDIMM operation, M378A2K43DB1-CTD delivers predictable bandwidth at JEDEC 2666 MT/s (PC4-21300U) and CL19 timings, supporting stable scheduling for virtualized services, light analytics, and general compute.

By operating at 1.2V and using a 288-pin, low-profile UDIMM layout, M378A2K43DB1-CTD fits space-constrained chassis while maintaining signal integrity across standard DDR4 topologies. As a dual-rank, 64-bit module, it can improve effective parallelism on compatible boards and complements PCIe-based expansion and NVMe storage designs by reducing memory-side stalls that can otherwise throttle I/O-driven workloads. This module is intended for platforms that explicitly support non-ECC UDIMM and is not suitable for systems requiring ECC RDIMM or LRDIMM.

Why Choose the M378A2K43DB1-CTD?

M378A2K43DB1-CTD is a pragmatic choice when density, compatibility, and deterministic JEDEC behavior matter more than registered buffering. It enables clean scale-out memory population in entry servers, appliances, and professional workstations that mandate UDIMM, providing straightforward deployment logic and consistent performance characteristics for standardized fleet configurations.

Samsung designs memory with a process-driven validation focus, aligning component selection and production screening to enterprise reliability expectations. The M378A2K43DB1-CTD reflects that discipline through standards-compliant operation and controlled tolerances that support repeatable qualification across modern data centre and edge infrastructure build-outs.

Key Applications:

• Workstation memory expansion for DDR4 UDIMM platforms
• Small business servers supporting non-ECC UDIMM
• Edge appliances and virtualization hosts with UDIMM slots
• General compute and I/O-balanced workloads
