Samsung 16GB 2Rx4 PC3L-12800R DDR3L-1600 ECC Registered RDIMM

The Samsung 16GB 2Rx4 PC3L-12800R-11-11-E2-D3 is a 16 GB DDR3L-1600 Registered DIMM (RDIMM) designed for enterprise servers, workstations, and high-density computing systems. It operates at a data rate of 1600 MT/s (PC3-12800) with low voltage 1.35V, providing improved power efficiency compared to standard 1.5V DDR3 modules while maintaining full compatibility in supported platforms.The module features a dual-rank (2Rx4) organization using x4 DRAM chips, resulting in higher memory density and better performance in multi-core server environments. It includes on-board register and ECC (Error-Correcting Code) functionality for enhanced data integrity and reliability, making it suitable for mission-critical applications such as virtualization, database servers, cloud infrastructure, and HPC (High-Performance Computing).

Key specifications include CAS latency CL11, 240-pin RDIMM form factor, and support for registered buffering that reduces electrical load on the memory controller, allowing stable operation in systems with large memory configurations (up to several terabytes depending on the platform). The module is fully JEDEC-compliant and supports thermal sensors for advanced temperature monitoring.

This low-voltage PC3L variant is backward compatible with many DDR3-1600 platforms that support 1.35V modules and is commonly used in servers from Dell, HP, IBM/Lenovo, Supermicro, and other OEMs. It features gold-plated contacts for reliable signal transmission and robust construction suitable for 24/7 operation in data center environments.

The Samsung 16GB PC3L-12800R module supports advanced features such as address mirroring, command/address parity, and on-die termination for signal integrity at high speeds. It is hot-pluggable in supported systems and designed for easy installation in standard DIMM slots.

Typical power consumption is significantly lower than standard voltage modules, contributing to reduced overall system heat and energy costs in large-scale deployments. The module undergoes rigorous testing for compatibility, stability, and long-term reliability in demanding server workloads.
