Description
The Kingston KSM48R40BS4III-32HMI is a 32GB DDR5 Registered DIMM (RDIMM) memory module engineered for high-performance computing environments, including servers and workstations. It operates at a rapid 4800MHz frequency with a CAS Latency of CL40, delivering substantial bandwidth and responsiveness for demanding applications. The DDR5 standard brings significant advancements in speed, efficiency, and capacity, making this module a powerful upgrade for modern systems. This module is configured as 1Rx4, indicating it is single-ranked with a data width of x4 per rank. This configuration is often preferred for its efficiency and performance characteristics in specific server workloads, particularly those that benefit from wider data paths. As an RDIMM, it includes an integrated register chip that buffers address and command signals, reducing the electrical load on the memory controller. This allows for higher memory densities and improved signal integrity, which are crucial for stable operation in complex server systems. Equipped with Error-Correcting Code (ECC) technology, the KSM48R40BS4III-32HMI is designed for environments where data integrity and system reliability are paramount. ECC memory can detect and correct common memory errors, preventing data corruption and minimizing downtime. This makes it an indispensable component for critical applications, databases, and mission-critical servers that require continuous and accurate operation.
