M393A4K40DB3-CWEGY Samsung 1x32GB DDR4 RDIMM ECC RAM

High-Density DDR4 Registered ECC RDIMM memory expansion with the M393A4K40DB3-CWEGY

The M393A4K40DB3-CWEGY is a 32GB DDR4-3200 Registered ECC RDIMM designed for enterprise server platforms that rely on buffered memory channels for stability at scale. In dual-socket compute nodes and virtualization hosts, the M393A4K40DB3-CWEGY supports predictable memory behavior under sustained load, aligning capacity upgrades with ECC requirements and validated DIMM population rules.

By using DDR4-3200 (PC4-25600E) with registered buffering and 72-bit ECC data protection, the M393A4K40DB3-CWEGY helps maintain signal integrity across populated channels while reducing the operational risk of memory-related faults. This module targets CPU platforms with DDR4 RDIMM memory controllers and is typically deployed alongside PCIe-based I/O and NVMe/SAS/SATA storage architectures where memory bandwidth and latency consistency directly influence VM density, database caching efficiency, and general-purpose compute throughput.

Why Choose the M393A4K40DB3-CWEGY?

The M393A4K40DB3-CWEGY is selected when you need a capacity-per-slot increase without compromising enterprise reliability characteristics expected from ECC RDIMM memory. For IT teams standardizing images across clusters, the M393A4K40DB3-CWEGY provides a scalable path to expand per-node memory footprints while keeping DIMM topology aligned with vendor-qualified DDR4-3200 RDIMM configurations.

Samsung engineering emphasizes JEDEC-compliant operation, consistent lot quality, and platform interoperability for data centre deployments. As a Samsung server memory module, this design prioritizes stable timings, controlled power characteristics at 1.2V, and long-term suitability for managed lifecycle environments.
