Product Description
The Samsung M386A8K40BM1-CRC5Q is a high-capacity 64GB DDR4 Load-Reduced DIMM (LRDIMM), identical in core specifications to the M386A8K40BM1-CRC. It operates at 2400MHz (PC4-19200) with a CAS Latency of CL17 and features a 4Rx4 (quad-rank) configuration. This module is designed for server environments that require maximum memory density and advanced memory management features. The LRDIMM architecture utilizes a buffer chip to reduce the electrical load on the memory controller, enabling higher memory capacities and improved signal integrity. The 4Rx4 configuration signifies a quad-rank design, where each rank is built using x4 memory chips. This setup can enhance performance in compatible server systems by allowing for more efficient interleaving of memory accesses across different ranks. This is particularly advantageous for memory-intensive applications such as large-scale virtualization, in-memory databases, and scientific simulations. As with other enterprise-grade memory, it includes ECC (Error-Correcting Code) capabilities to detect and correct memory errors, ensuring data integrity and system stability. The '5Q' suffix in the part number typically indicates a specific manufacturing revision, packaging, or a particular batch from Samsung. While the core technical specifications remain the same as the base part number, it's always advisable to check system compatibility lists for any specific revision requirements. This module is intended for high-end servers and workstations that support DDR4 LRDIMMs at 2400MHz, providing a robust solution for environments demanding extensive memory resources.
