Product Description
The Samsung M386A8K40BMB-CPB40 is a high-density 64GB Load-Reduced Dual In-line Memory Module (LRDIMM) engineered for enterprise-level computing environments. It leverages DDR4 technology to deliver superior bandwidth and power efficiency compared to previous generations. The LRDIMM design incorporates a memory buffer chip that reduces electrical loading on the memory controller, allowing for higher capacities and improved signal integrity in systems with many memory modules. This module operates at a frequency of 2133MHz, often referred to as PC4-17000, and features a CAS Latency (CL) of 15. The 4Rx4 configuration indicates that the memory is organized into four ranks, with each rank consisting of x4 (4-bit wide) DRAM devices. This configuration is optimized for servers that require maximum memory bandwidth and capacity. The inclusion of Registered ECC (Error-Correcting Code) ensures data integrity and system stability, crucial for mission-critical applications and continuous operation. Designed for compatibility with servers and high-end workstations that support DDR4 LRDIMM memory, this module is an ideal upgrade for systems requiring substantial memory resources. Its robust design and Samsung's reputation for quality make it a reliable choice for demanding workloads such as virtualization, large databases, scientific simulations, and high-performance computing. The 1.2V operating voltage contributes to reduced power consumption and heat generation within the server chassis.
