M393B5273DH0-YH9 Samsung 1x4GB DDR3 ECC RAM

Enterprise DDR3 ECC Registered RDIMM for Legacy Server Expansion with the M393B5273DH0-YH9

The M393B5273DH0-YH9 is a Samsung DDR3 RDIMM designed for x86 server platforms that require ECC Registered memory to maintain stability under continuous operation. As a 240-pin, 72-bit module, it integrates with server-class memory channels that rely on registered buffering for signal integrity and predictable behavior across populated DIMM banks.

Engineered as DDR3-1333 (PC3-10600R) at 1.5V with CL9 timings, the M393B5273DH0-YH9 supports balanced bandwidth and latency for legacy virtualization nodes, directory services, and control-plane workloads where deterministic memory operation matters more than peak throughput. Its dual-rank x8 organization improves compatibility with common DDR3-era memory controllers and population rules, while ECC protection helps detect and correct single-bit errors to reduce soft-failure risk. In platforms constrained to PCIe Gen2/Gen3 and SATA/SAS storage architectures, the M393B5273DH0-YH9 is a practical option for sustaining serviceability, spares management, and capacity right-sizing without introducing non-standard profiles such as XMP/EXPO.

Why Choose the M393B5273DH0-YH9?

The M393B5273DH0-YH9 delivers a reliable density-to-compatibility fit for DDR3 RDIMM servers where uptime and consistent memory training are priorities. It is well suited for incremental expansion, replacement of failed modules, and fleet standardization across matched configurations, enabling predictable scaling and straightforward operational planning in established environments.

Samsung focuses on enterprise memory engineering with emphasis on qualification, controlled component selection, and long-run consistency. This approach supports data centre standards for stability, maintainability, and validated interoperability in server platforms that continue to operate in labs, edge sites, and legacy production roles.

Key Applications:

• Legacy x86 server memory expansion
• Spare module inventory for DDR3 fleets
• Lab and development server builds
