Samsung 16GB 2Rx4 PC3L-12800R-11-12-E2-P3 DDR3L-1600 ECC Registered RDIMM

The Samsung 16GB 2Rx4 PC3L-12800R-11-12-E2-P3 is a 16 GB low-voltage DDR3L-1600 Registered DIMM (RDIMM) engineered for enterprise servers and high-reliability computing platforms. It operates at 1600 MT/s (PC3-12800) with a reduced voltage of 1.35 V, offering lower power consumption and reduced heat generation compared to standard 1.5 V DDR3 modules while maintaining full compatibility in supported server architectures.This module utilizes a dual-rank (2Rx4) configuration based on x4 DRAM organization, providing high memory density and optimized performance in multi-processor and multi-core server environments. It incorporates registered buffering to lighten the electrical load on the memory controller, enabling stable operation in systems with large memory populations. ECC (Error-Correcting Code) support ensures enhanced data integrity by detecting and correcting single-bit errors, which is essential for mission-critical applications such as virtualization, database servers, cloud computing, and data center workloads.

The module complies with JEDEC specifications and features CAS latency CL11, 240-pin RDIMM form factor, and advanced signal integrity features including on-die termination, address mirroring, and command/address parity. It is designed for 24/7 operation with robust thermal characteristics and includes temperature monitoring capabilities in compatible platforms.

This PC3L variant is widely used in servers from major OEMs including Dell, HPE, Lenovo, Supermicro, and others that support low-voltage registered DDR3 memory. The gold-plated contacts ensure reliable long-term signal transmission, and the module supports hot-plug functionality in systems that allow memory expansion without downtime.

Key operational advantages include reduced system power draw, lower cooling requirements, and improved energy efficiency in dense rack deployments. The Samsung 16GB PC3L-12800R-11-12-E2-P3 undergoes strict factory testing for compatibility, stability, and reliability under heavy server workloads.

It is fully backward compatible with many DDR3-1600 server platforms that accept 1.35 V RDIMMs and integrates seamlessly into existing memory configurations for capacity upgrades or replacements. The module is supplied as a single 16 GB stick in the standard 240-pin RDIMM package.
