Samsung M393B1K70CH0-CH9Q5 8GB 2Rx4 PC3-10600R DDR3-1333 ECC Registered RDIMM

The Samsung M393B1K70CH0-CH9Q5 is an 8 GB DDR3-1333 Registered DIMM (RDIMM) designed for enterprise servers and high-reliability computing platforms. It operates at 1333 MT/s (PC3-10600 / PC3-10600R) with standard 1.5 V voltage, providing stable performance in multi-processor server environments.This module features a dual-rank (2Rx4) organization using x4 DRAM chips, which offers good memory density and efficient bandwidth utilization for server workloads. Registered buffering reduces the electrical load on the memory controller, enabling stable operation with multiple DIMMs per channel and larger overall memory configurations. ECC (Error-Correcting Code) support allows detection and correction of single-bit errors, ensuring high data integrity required for mission-critical applications such as database servers, virtualization platforms, cloud infrastructure, and telecommunications systems.
Key specifications include CAS latency CL9, 240-pin RDIMM form factor, and full JEDEC compliance. The module supports advanced signal integrity features including on-die termination, address mirroring, and command/address parity checking. Gold-plated contacts provide reliable long-term connectivity and corrosion resistance.
The Samsung M393B1K70CH0-CH9Q5 is widely compatible with major server platforms from Dell, HPE, Lenovo, IBM, Supermicro, and other OEMs that support DDR3-1333 registered ECC memory. It is engineered for 24/7 operation in data center environments with robust thermal characteristics and supports temperature monitoring in compatible systems.
This RDIMM variant is particularly suitable for servers requiring registered memory for improved stability and capacity scaling. The module undergoes rigorous factory testing for compatibility, stability, and reliability under sustained heavy server loads. It allows straightforward capacity upgrades or replacements in existing DDR3 server platforms without full system overhaul.
Power consumption is optimized for enterprise use, contributing to manageable heat dissipation and energy efficiency in rack-mounted deployments. The standard 240-pin RDIMM package ensures easy installation in standard server memory slots.
