Product Description
The Samsung M386A8K40BM1-CRC is a high-capacity 64GB DDR4 Load-Reduced DIMM (LRDIMM). This module is engineered for server environments that demand maximum memory density and performance. It operates at a speed of 2400MHz (PC4-19200) with a CAS Latency of CL17, providing substantial bandwidth for data-intensive workloads. The LRDIMM architecture includes a memory buffer chip that isolates the memory controller from the memory modules, reducing electrical load and enabling higher memory configurations and speeds. The 4Rx4 configuration indicates that this is a quad-rank module, with each rank composed of four memory chips (x4). Quad-rank modules offer increased performance in certain server platforms by allowing the memory controller to interleave operations across multiple ranks more effectively. This design is particularly beneficial for applications such as large databases, virtualization, and high-performance computing where access to vast amounts of data is critical. Like other server-grade memory, it incorporates ECC (Error-Correcting Code) to ensure data integrity and system reliability. This Samsung LRDIMM is a premium component for enterprise-grade servers, designed to support systems requiring extensive memory resources. Its high density and advanced architecture make it suitable for mission-critical applications where uptime and data accuracy are essential. Compatibility is key, and this module should only be used in servers and motherboards explicitly supporting DDR4 LRDIMMs at 2400MHz.
