Product Description
This Samsung M386B4G70BM0-YH90 memory module provides a substantial 32GB of capacity, making it suitable for memory-intensive applications and server environments that require significant RAM. As a DDR3 LRDIMM, it incorporates features that enhance signal integrity and allow for higher memory densities compared to standard UDIMMs or RDIMMs. This is achieved through the use of a memory buffer chip that reduces the electrical load on the memory controller. The module operates at a frequency of 1333MHz with a CAS Latency of 9, offering a good balance between speed and responsiveness for a wide range of server workloads. The 4Rx4 rank configuration signifies that each memory module is composed of four ranks, with each rank having 4 bits of data width per chip. This configuration can lead to improved performance in systems that support multi-rank memory configurations, as it allows for more parallel access to the memory. Designed primarily for server and workstation platforms, the M386B4G70BM0-YH90 is built for reliability and stability under continuous operation. Its LRDIMM design is particularly beneficial in systems with many memory slots, as it helps maintain signal quality and allows the system to populate more memory modules without encountering signal degradation issues. This makes it an excellent choice for virtualization, large databases, and high-performance computing tasks.
