Product Description
This Samsung memory module, part number M386A8K40CM2-CVFBQ, is a high-capacity 64GB DDR4 Load-Reduced DIMM (LRDIMM). LRDIMMs are specifically designed for servers that require very large amounts of memory. They incorporate a memory buffer chip that isolates the memory controller from the DRAM devices, significantly reducing the electrical load and allowing for higher densities and more modules per channel compared to standard RDIMMs. The module operates at a high speed of 2933MHz, providing substantial bandwidth crucial for data-intensive server workloads such as in-memory databases, large-scale virtualization, and high-performance computing. The CAS Latency (CL) is 21, which is typical for DDR4 modules at this speed. The module features a quad-rank (4Rx4) configuration, offering further potential for performance gains through rank interleaving, allowing the memory controller to access different ranks concurrently. With a capacity of 64GB, this DDR4 LRDIMM is ideal for upgrading servers to meet the demands of modern enterprise applications that require vast amounts of RAM. The 1.2V operating voltage is standard for DDR4 memory. As with all server memory, compatibility with the specific server model, motherboard, and CPU is essential before installation.
