M393A4K40CB1-CRC Samsung 1x32GB DDR4 ECC RAM

Enterprise DDR4 RDIMM Memory Expansion featuring ECC Registered Architecture with the M393A4K40CB1-CRC

The M393A4K40CB1-CRC is a Samsung 32GB DDR4 ECC Registered DIMM engineered to increase memory capacity and reliability in mainstream dual-socket server platforms running Intel Xeon Scalable or AMD EPYC generations that rely on DDR4 RDIMM channels. By using a registered buffer and ECC, the M393A4K40CB1-CRC supports stable operation under sustained CPU memory-controller load, helping reduce soft-error impact in virtualized and general-purpose compute nodes.

Designed for JEDEC-compliant 288-pin RDIMM slots, the M393A4K40CB1-CRC integrates cleanly into standard BIOS memory training without XMP/EXPO dependencies. Its DDR4-2400 (PC4-19200) data rate and CL17 timing align with predictable latency profiles for CPU-bound services, while the dual-rank x4 organization improves signal integrity characteristics commonly preferred in dense enterprise configurations. This module complements platforms where PCIe expansion and storage throughput depend on consistent memory availability, ensuring I/O-heavy workloads are not constrained by memory instability.

Why Choose the M393A4K40CB1-CRC?

The M393A4K40CB1-CRC delivers a practical density-to-reliability balance for scale-out deployments where node uniformity matters. ECC RDIMM operation supports enterprise uptime objectives, and the 32GB capacity point enables efficient population strategies across multiple channels for balanced bandwidth and predictable scalability as VM counts and dataset footprints grow.

Samsung server DRAM is designed with a focus on validation depth, long-life supply discipline, and electrical compliance with modern data center standards. This approach supports consistent interoperability across qualified server boards and helps maintain predictable behavior during firmware updates and hardware refresh cycles.

Key Applications:

• Server memory expansion for DDR4 RDIMM platforms
• Virtualization and VM consolidation
• General-purpose compute nodes
• Infrastructure services and middleware
• Database and caching tiers
