Hynix HMCT14MEERA144N 256GB DDR5-4800MHz RDIMM 8Rx4 CL40 Memory

Product Description

The Hynix HMCT14MEERA144N is an exceptionally high-capacity 256GB DDR5 Registered DIMM (RDIMM), engineered for the most demanding server applications. This module leverages the latest DDR5 technology to deliver superior performance, efficiency, and density. Operating at a speed of 4800MHz, it provides massive bandwidth crucial for data-intensive workloads. The unique 8Rx4 configuration signifies an eight-rank design with four data bits per channel, allowing for an unprecedented amount of memory capacity on a single DIMM while optimizing access patterns for high-end server controllers. DDR5 technology introduces significant architectural improvements over its predecessors, including enhanced signal integrity, on-die ECC for improved reliability, and a dedicated power management IC (PMIC) on the module itself for finer voltage control and power efficiency. As an RDIMM, it features an onboard register that buffers command and address signals, reducing the electrical load on the memory controller. This is essential for supporting the vast number of DIMMs required for 256GB modules and enabling extremely high total system memory capacities. With a CAS Latency of CL40, this 256GB DDR5 RDIMM is optimized for enterprise-grade performance, suitable for applications such as massive in-memory databases, large-scale scientific computing, advanced virtualization, and high-performance cloud infrastructure. The combination of its enormous capacity, high speed, and robust DDR5 features makes the HMCT14MEERA144N a critical component for next-generation servers pushing the boundaries of computational power and data handling.
