M393A2K40EB3-CWE Samsung 1x16GB DDR4 RDIMM ECC RAM

Enterprise DDR4 RDIMM Memory Expansion featuring ECC Registered Reliability with the M393A2K40EB3-CWE

The M393A2K40EB3-CWE is a Samsung 16GB DDR4 RDIMM designed for ECC-capable server platforms where deterministic memory behavior and validated signal integrity are required. The M393A2K40EB3-CWE operates at 3200MT/s (PC4-25600R) to support balanced CPU feed on modern multi-socket compute nodes, enabling stable performance for consolidation and general-purpose workloads without introducing unregistered DIMM limitations.

Built as a 288-pin, 72-bit ECC Registered DIMM, the M393A2K40EB3-CWE is optimized for platforms that rely on the register to reduce electrical loading and preserve memory channel scalability as DIMM counts increase. Its single-rank x4 organization aligns with enterprise reliability goals, while the low-profile mechanical format improves fitment in dense rack servers with constrained airflow paths. The module’s JEDEC timing profile at CL22-22-22 and 1.2V supports predictable configuration across mixed-population DDR4 RDIMM designs, helping maintain system stability alongside PCIe expansion and storage I/O demands typical in virtualization clusters.

Why Choose the M393A2K40EB3-CWE?

The M393A2K40EB3-CWE provides a pragmatic density-to-performance step for DDR4 infrastructures, enabling incremental capacity growth without redesigning the node architecture. By using ECC and registered buffering, the M393A2K40EB3-CWE supports higher-confidence uptime and scalable memory channel population, which is critical when nodes must remain consistent across racks, firmware baselines, and lifecycle refresh cycles.

Samsung engineers server memory for long service life under sustained thermal and electrical stress, emphasizing JEDEC compliance, platform interoperability, and controlled manufacturing quality suited to enterprise change management. This approach supports repeatable deployment standards in modern data centres where validation and predictability are paramount.
