M393B1K70DH0-CK0 Samsung 1x8GB DDR3 ECC RAM

Enterprise DDR3 RDIMM Server Memory Upgrade featuring ECC Registered Reliability with the M393B1K70DH0-CK0

The M393B1K70DH0-CK0 is a Samsung DDR3 ECC Registered DIMM designed for legacy DDR3-based server platforms where stability and predictable behaviour are more critical than raw frequency scaling. As an 8GB dual-rank RDIMM, it supports registered memory channels to reduce electrical loading on the CPU’s integrated memory controller, enabling cleaner signalling and better population flexibility in dense DIMM configurations.

In Xeon and Opteron-era architectures, memory capacity and channel integrity directly affect virtualisation density, database caching, and I/O buffering. The M393B1K70DH0-CK0 operates at DDR3-1600 (1600MT/s) with CL11 timings at 1.5V, providing a balanced profile for PCIe-attached storage controllers, NICs, and RAID/HBA expansion where workload consistency matters. ECC with a 72-bit data path helps protect long-running services from single-bit errors, supporting fleet extensions, controlled capacity expansion, and maintenance windows without introducing a platform redesign.

Why Choose the M393B1K70DH0-CK0?

The M393B1K70DH0-CK0 is a practical upgrade path for DDR3 servers that must remain in service for compliance, application compatibility, or staged refresh cycles. It improves density-to-cost efficiency through targeted 8GB increments while preserving RDIMM reliability characteristics, helping administrators scale memory footprints in a controlled way across multi-socket systems and mixed-load clusters.

Samsung designs enterprise memory with a focus on signal integrity, qualification discipline, and lifecycle consistency aligned to data centre operational standards. The M393B1K70DH0-CK0 follows this approach to support dependable deployment in validated server configurations and change-managed environments.

Key Applications:

• Legacy server memory expansion
• Virtualisation host RAM upgrades
• Small database and cache tiering
• Infrastructure services consolidation
