Description
The Samsung M386A8K40DM2-CWEZY is a high-performance 64GB DDR4 Load-Reduced DIMM (LRDIMM), engineered to meet the demanding memory requirements of modern servers. LRDIMMs are specifically designed to overcome the electrical loading limitations of traditional RDIMMs, allowing for significantly higher memory capacities and densities per channel. This module operates at a rapid 3200MHz speed, translating to a PC4-25600 bandwidth, which is crucial for data-intensive applications and large-scale virtualization environments. The 4Rx4 configuration signifies a quad-rank design, where each rank utilizes x4 DRAM devices. This multi-rank architecture, combined with the LRDIMM's inherent design, maximizes memory bandwidth and allows server systems to populate more memory modules, achieving unprecedented total memory capacities. The inclusion of a memory buffer chip on LRDIMMs isolates the DRAM devices from the memory controller, reducing the electrical load and enabling higher memory speeds and greater module counts. As with most server-grade memory, this module supports ECC (Error-Correcting Code) functionality, which is vital for maintaining data integrity and system stability in mission-critical applications. The CL22 CAS Latency provides a balance between performance and reliability. The M386A8K40DM2-CWEZY is an excellent choice for servers that require the utmost in memory capacity, bandwidth, and stability, such as those used for big data analytics, complex simulations, and large enterprise databases.
