Description
This Kingston memory module, identified by SKU KSM48P40BD4III-64HMR, leverages the advanced DDR5 technology to deliver superior performance for demanding computing tasks. With a substantial 64GB capacity, it is ideal for memory-intensive applications such as large-scale data analysis, virtualization, and complex simulations. The RDIMM form factor incorporates on-module registers to reduce electrical load on the memory controller, enhancing stability and allowing for higher memory capacities and speeds in server systems. The module's 4800MHz clock speed signifies a significant leap in data transfer rates compared to DDR4, enabling faster processing and improved system responsiveness. The 2Rx4 configuration indicates a dual-rank design with x4 data-wide DRAM chips, which can further optimize memory access patterns and bandwidth utilization in compatible server platforms. The CL40 latency, while higher than some lower-density modules, is balanced by the increased clock speed and architectural improvements of DDR5, ensuring overall system efficiency. As a server-grade component, the KSM48P40BD4III-64HMR includes Error-Correcting Code (ECC) functionality. ECC memory detects and corrects single-bit errors on the fly, preventing data corruption and system crashes, which is critical for maintaining data integrity and uptime in mission-critical server environments. This module is engineered for reliability and performance, making it a robust choice for enterprise-level computing infrastructure.
