Samsung M386B4G70BM0-YH921 32GB DDR3-1333MHz LRDIMM 4Rx4 CL9 Memory

Product Description

The Samsung M386B4G70BM0-YH921 is a high-capacity 32GB DDR3 Load-Reduced DIMM (LRDIMM) memory module, engineered for servers and workstations that require maximum memory density and performance. LRDIMMs are designed to overcome the electrical limitations of traditional RDIMMs, allowing for significantly higher memory capacities per channel and per system. This is achieved through the use of a memory buffer chip on the module, which isolates the memory controller from the DRAM devices, reducing the electrical load and enabling more memory modules to be installed. This module operates at a speed of 1333MHz (PC3-10600), providing ample bandwidth for memory-intensive applications commonly found in enterprise environments, such as large databases, virtualization platforms, and high-performance computing. The CAS Latency (CL) of 9 offers a good balance between speed and latency for DDR3 technology. The 4Rx4 configuration indicates that the module is composed of four ranks, each using x4 data-wide DRAM chips, which contributes to its high capacity and performance profile in compatible server architectures. As an LRDIMM, the M386B4G70BM0-YH921 also includes ECC (Error-Correcting Code) capabilities. ECC memory is essential in server environments for detecting and correcting single-bit memory errors, and detecting multi-bit errors, thereby preventing data corruption and ensuring system stability and reliability. This 32GB module is an ideal choice for upgrading existing server systems or configuring new ones that demand substantial memory resources for demanding workloads, while benefiting from the enhanced signal integrity and capacity scaling offered by the LRDIMM form factor.
