M393B2K70CM0-CF8 Samsung 1x16GB DDR3 RDIMM ECC RAM

Enterprise DDR3 RDIMM Memory Expansion featuring Registered ECC reliability with the M393B2K70CM0-CF8

The M393B2K70CM0-CF8 is a 16GB Samsung DDR3 Registered ECC RDIMM designed for legacy DDR3 Xeon and Opteron server platforms where predictable memory behavior and validated buffering are required. Deployed into CPU generations that rely on integrated memory controllers tuned for DDR3 RDIMM signaling, this module supports stable channel loading and consistent training outcomes in multi-DIMM per channel configurations.

As a 240-pin DIMM with ECC and registered buffering, the M393B2K70CM0-CF8 aligns with enterprise platforms that prioritize uptime over peak bandwidth, making it suitable for capacity expansion and service stock replacement. While PCIe and storage characteristics are dictated by the host server, memory integrity directly influences I/O paths, virtualization density, and database cache residency; this RDIMM helps maintain data-path correctness under sustained workload cycles and mixed access patterns.

Why Choose the M393B2K70CM0-CF8?

The M393B2K70CM0-CF8 delivers a pragmatic density-to-stability profile for environments extending the lifecycle of DDR3 infrastructure. With registered ECC operation and quad-rank organization, it supports scale-up memory footprints in compatible systems, enabling controlled consolidation and predictable fail-domain behavior for nodes that must remain in service without disruptive platform refresh.

Samsung memory engineering emphasizes qualification discipline, signal integrity, and long-term availability for data centre operations. The M393B2K70CM0-CF8 reflects this focus through standards-aligned RDIMM design intended to integrate cleanly with enterprise BIOS memory reference code, OEM validation matrices, and operational practices for spares management.

Key Applications:

• Legacy server memory capacity expansion
• Spare and replacement RDIMM inventory
• Virtualization on DDR3-era hosts
• Database and in-memory caching on legacy nodes
• General-purpose enterprise compute refresh avoidance
