This Kingston 64GB registered DDR5 ECC memory module is designed for servers and workstations that support DDR5 RDIMM memory, running at 6400MT/s with CL52 timings in a dual-rank (2Rx4) layout, built using Micron 'D' DRAM chips. Like other ECC registered DIMMs, it automatically detects and corrects single-bit memory errors — essential for long-running server workloads, databases, and virtualization hosts where data integrity matters more than raw cost savings. The registered (buffered) design reduces electrical load on the host's memory controller, allowing more DIMMs to be populated per channel at higher capacities and speeds than unbuffered memory would allow. Typically deployed in matched multi-module kits to maximise a server's total memory bandwidth.
