Samsung M393B1K70DH0-YH9 8GB 2Rx4 PC3L-10600R DDR3L-1333 ECC Registered RDIMM

The Samsung M393B1K70DH0-YH9 is an 8 GB low-voltage DDR3L-1333 Registered DIMM (RDIMM) designed for enterprise servers and high-reliability computing platforms. It operates at 1333 MT/s (PC3-10600R / PC3L-10600R) and supports both 1.35 V and 1.5 V voltages, providing improved energy efficiency at low voltage while maintaining broad compatibility with server memory controllers.This module features a dual-rank (2Rx4) organization with x4 DRAM chips, offering balanced density and efficient bandwidth utilization in multi-processor environments. Registered buffering reduces the electrical load on the memory controller and address/command lines, enabling stable operation with multiple DIMMs per channel and larger total memory configurations. ECC (Error-Correcting Code) support ensures detection and correction of single-bit errors, which is critical for mission-critical applications such as database servers, virtualization, cloud infrastructure, and telecommunications systems.
Key specifications include CAS latency CL9, 240-pin RDIMM form factor, and full JEDEC compliance. The module incorporates advanced signal integrity features including on-die termination, address mirroring, and command/address parity checking. Gold-plated contacts guarantee reliable long-term signal transmission and corrosion resistance in data center conditions.
The Samsung M393B1K70DH0-YH9 is widely compatible with major server platforms from Dell, HPE, Lenovo, IBM, Supermicro, and other OEMs that support DDR3-1333 registered ECC low-voltage memory. It is engineered for continuous 24/7 operation with robust thermal performance and supports temperature monitoring in compatible systems.
This PC3L variant is particularly suitable for servers that benefit from reduced power consumption and lower heat generation. The module undergoes rigorous factory testing to ensure compatibility, stability, and reliability under heavy sustained workloads. It allows straightforward capacity upgrades or replacements in existing DDR3 server platforms without requiring a full system overhaul.
Power consumption is optimized for enterprise use, contributing to lower overall system energy costs and reduced cooling requirements in dense rack deployments. The standard 240-pin RDIMM package ensures easy installation in standard server DIMM slots.
