Description
The Samsung M321RBGA0B40-CWKZH is a cutting-edge 256GB DDR5 Registered DIMM (RDIMM), representing the forefront of server memory technology. DDR5 introduces significant architectural improvements over DDR4, including higher speeds, increased density, and enhanced power efficiency. This module's 4800MHz speed provides massive bandwidth, crucial for data-intensive applications like AI/ML, large-scale simulations, and high-performance computing (HPC) environments. This RDIMM features an 8Rx4 configuration, meaning it is octal-ranked with memory chips that have a 4-bit data width. This high rank count, combined with DDR5's advanced features like on-die ECC and dual 40-bit channels per module, allows for exceptional memory performance and reliability in dense server configurations. The CL40 latency is characteristic of DDR5 at these high speeds, where architectural changes prioritize bandwidth and efficiency over absolute latency. Designed for the most demanding server platforms, this 256GB module enables unprecedented memory capacities per socket, supporting massive datasets and complex workloads. Samsung's reputation for quality ensures that this module meets the stringent reliability and performance requirements of modern data centers and enterprise infrastructure.
