Technical Architecture & Memory Specifications
This Samsung DDR5 server memory is engineered for next-generation enterprise workloads, featuring a highly efficient 1Rx8 (Single Rank x8) organization. Operating at a blazing fast 5600 MT/s (PC5-44800) with a CAS Latency of CL46, it delivers massive bandwidth improvements over previous generations. The module runs at an ultra-low 1.1V, reducing power consumption and thermal output in dense server environments. As a Registered DIMM (RDIMM), it utilizes a hardware register to buffer control and command signals, ensuring maximum stability and data integrity under heavy loads.
Platform Compatibility & Server/Desktop Application
This 288-pin ECC RDIMM is strictly designed for enterprise servers and high-end workstations. It is optimized for modern DDR5-compatible server architectures, including Intel Xeon Scalable processors and AMD EPYC platforms that support DDR5 Registered memory. Important Note: This is server-grade ECC Registered memory. It is NOT compatible with standard consumer desktop motherboards (which require Unbuffered UDIMMs) or laptops (which require SO-DIMMs).
