Description
The Samsung M386AAK40B40-CUC4Q is a high-capacity 128GB LRDIMM (Load-Reduced Dual In-line Memory Module) designed for server and workstation environments that require significant memory bandwidth and capacity. Operating at a speed of 2400MHz (also known as PC4-19200), this module is built to enhance the performance of systems handling large datasets, complex computations, and extensive virtualization. The LRDIMM form factor is crucial for achieving higher memory capacities per channel compared to standard RDIMMs. This is because LRDIMMs incorporate a memory buffer chip that reduces the electrical load on the memory controller, allowing more modules to be installed in a system. The 8Rx4 configuration indicates that the module is composed of eight ranks, with each rank consisting of four data chips, further contributing to its high density and performance characteristics. With a CAS Latency (CL) of 17, this memory module offers a balance between speed and stability. It also supports ECC (Error-Correcting Code) functionality, which is essential in server environments for detecting and correcting memory errors, thereby ensuring data integrity and system reliability. This module is ideal for memory-intensive applications and enterprise-grade computing platforms.
