Samsung M386B4G70DM0-YK040 32GB DDR3-1600MHz LRDIMM 4Rx4 CL11 Memory

Product Description

The Samsung M386B4G70DM0-YK040 is a 32GB DDR3 Load-Reduced DIMM (LRDIMM) memory module, engineered for high-capacity server memory configurations. LRDIMMs are designed to overcome the limitations of traditional RDIMMs by incorporating an additional buffer chip (an 8-bit buffer) that isolates the memory controller from the memory ranks. This significantly reduces the electrical load, allowing for higher memory densities and more memory modules to be populated per channel. This module operates at a speed of 1600MHz, corresponding to the PC3-12800 standard, and features a CAS Latency (CL) of 11. While LRDIMMs generally have slightly higher latency than RDIMMs due to the buffer chip, they excel in enabling greater total system memory capacity, which is often more critical in server environments. The 4Rx4 configuration indicates four ranks, each with four data bits, contributing to its high capacity. As an ECC (Error-Correcting Code) memory module, the M386B4G70DM0-YK040 provides enhanced data integrity by detecting and correcting memory errors. This is a standard and essential feature for server-grade memory, ensuring the reliability of critical data processing. The module operates at the standard DDR3 voltage of 1.5V, making it compatible with DDR3 server platforms that support LRDIMMs.
