M393B2K70CM0-YF8 Samsung 1x16GB DDR3 RDIMM ECC RAM

Enterprise DDR3L ECC Registered RDIMM memory expansion with the M393B2K70CM0-YF8 for legacy server platforms

The M393B2K70CM0-YF8 is a Samsung 16GB DDR3L ECC Registered DIMM designed for DDR3-era Xeon and Opteron server generations that depend on registered buffering for stable multi-DIMM channel population. In these CPU platforms, the RDIMM architecture improves signal integrity under higher electrical load, enabling predictable scaling when expanding memory footprints across dense virtualization hosts and database nodes.

With a 72-bit ECC data path, the M393B2K70CM0-YF8 supports enterprise error detection and correction to reduce the operational risk of single-bit faults in long-running services. Its PC3L-8500R 1066 MT/s operating profile, low 1.35V DDR3L power envelope, and low-profile 240-pin form factor align with airflow-constrained chassis designs while maintaining compatibility with qualified DDR3 RDIMM memory controllers. For systems engineered around PCIe Gen2/Gen3 I/O and SAS/SATA storage, the M393B2K70CM0-YF8 focuses on memory-side reliability and capacity density to keep established platforms serviceable without introducing architectural change.

Why Choose the M393B2K70CM0-YF8?

The M393B2K70CM0-YF8 is built for controlled, like-for-like capacity expansion where platform validation matters more than peak bandwidth. Its registered, ECC-protected design supports higher population scenarios and consistent uptime characteristics, making it suitable for phased upgrades, spares strategy, and maintaining performance-per-rack in legacy estates with defined change-control requirements.

Samsung’s enterprise memory engineering emphasizes process consistency, qualification discipline, and long-term operational stability, aligning the module with data centre standards for predictable interoperability, serviceability, and lifecycle management in production server environments.

Key Applications:

• DDR3 RDIMM server memory expansion
• Virtualization host capacity upgrades
• Legacy database servers
• Like-for-like replacement and spares
• Branch and edge infrastructure refresh
