Product Description
The Samsung M386A8K40DM2-CWE is a high-capacity 64GB DDR4 Load-Reduced DIMM (LRDIMM) memory module. LRDIMMs are designed to allow for greater memory capacity and higher memory speeds in server systems by using a memory buffer chip that reduces the electrical load on the memory controller. This makes them ideal for servers that require maximum memory configurations for demanding applications like large-scale virtualization, big data analytics, and high-performance computing. Operating at a speed of 3200MHz (PC4-25600), this module provides excellent performance for data-intensive tasks. It features a CAS Latency (CL) of 22, which is a standard for DDR4 memory at this speed. The 4Rx4 configuration signifies a quad-rank design with a x4 data width per rank, enabling higher memory density and potentially improved bandwidth utilization in compatible systems. This configuration is often found in high-end server memory solutions. As a DDR4 LRDIMM, the M386A8K40DM2-CWE includes Error-Correcting Code (ECC) functionality, which is essential for server environments to detect and correct memory errors, thereby ensuring data integrity and system stability. The module operates at a standard voltage of 1.2V, contributing to power efficiency within the server infrastructure. This memory module is a robust choice for enterprise servers needing significant memory capacity and reliable performance.
