M393A1G43DB0-CPB Samsung 1x8GB DDR4 ECC RAM

Enterprise DDR4 RDIMM ECC Memory Expansion for Stable Server Platforms with the M393A1G43DB0-CPB

The M393A1G43DB0-CPB is a Samsung DDR4 RDIMM ECC module engineered for predictable performance and signal integrity in enterprise server and workstation platforms that require registered memory. As a 288-pin DIMM built to JEDEC DDR4-2133 (PC4-17000R), it targets balanced throughput and latency characteristics for mixed CPU-bound and memory-sensitive workloads, while maintaining compatibility with ECC-capable DDR4 chipsets and validated memory topologies.

In dual-rank x4 organization with a 72-bit data path, the M393A1G43DB0-CPB supports ECC workflows that prioritize uptime and data correctness in multi-socket systems and dense virtualization hosts. Registered buffering helps sustain stability as DIMM population increases across channels, aligning well with platforms where PCIe and storage expansion depend on consistent memory behavior under load. This makes the M393A1G43DB0-CPB a practical building block for incremental capacity planning, legacy DDR4 refresh cycles, and controlled lab environments where repeatable configuration is essential.

Why Choose the M393A1G43DB0-CPB?

The M393A1G43DB0-CPB delivers an efficient density-to-reliability profile for DDR4 RDIMM infrastructures, enabling standardized spares, straightforward scaling, and reduced risk when expanding populated memory banks. With ECC support and registered design, the M393A1G43DB0-CPB fits deployments where stability, platform validation, and predictable operation matter more than peak bandwidth.

Samsung designs enterprise DRAM with a focus on process consistency, stringent validation, and long-term supply continuity, supporting data centre standards for interoperability and controlled lifecycle management.

Key Applications:

• Server memory expansion for DDR4 RDIMM platforms
• Virtualization and VDI lab density
• General-purpose compute nodes
