Samsung M393B1K70DH0-CH9Q9 8GB 2Rx4 PC3-10600R DDR3-1333 ECC Registered RDIMM

The Samsung M393B1K70DH0-CH9Q9 is an 8 GB DDR3-1333 Registered DIMM (RDIMM) engineered for enterprise servers and high-availability computing systems. Operating at 1333 MT/s (PC3-10600R), this module delivers reliable performance in multi-socket server environments while supporting Error-Correcting Code (ECC) for enhanced data integrity.The module utilizes a dual-rank (2Rx4) architecture with x4 DRAM organization, providing balanced density and efficient bandwidth utilization for typical server workloads. Registered buffering significantly reduces the electrical load on the memory controller and address lines, allowing stable operation with higher numbers of DIMMs per channel and supporting larger total memory configurations. ECC functionality enables detection and correction of single-bit errors, making it suitable for mission-critical applications including database servers, virtualization, cloud infrastructure, and telecommunications equipment.

Key technical parameters include CAS latency CL9, 240-pin RDIMM form factor, and full compliance with JEDEC standards. The module incorporates advanced signal integrity technologies such as on-die termination, address mirroring, and command/address parity. Gold-plated contacts ensure excellent long-term reliability and corrosion resistance in data center conditions.

This Samsung M393B1K70DH0-CH9Q9 RDIMM is compatible with a wide range of server platforms from Dell, HPE, Lenovo, IBM, Supermicro, and other major OEMs that support DDR3-1333 registered ECC memory. It is designed for continuous 24/7 operation with robust thermal performance and supports temperature monitoring capabilities in compatible server systems.

The module is particularly well-suited for servers requiring registered memory to achieve stable high-capacity configurations. It undergoes strict factory testing to guarantee compatibility, stability, and reliability under heavy sustained workloads. Easy installation in standard DIMM slots allows straightforward memory upgrades or replacements in existing DDR3-based servers.

Power consumption is optimized for enterprise environments, helping to maintain manageable heat levels and energy efficiency in dense rack deployments. The standard 240-pin RDIMM package ensures compatibility with most server memory slots without requiring additional adapters.
