Kingston Technology Corp. KSM64R52BD4-64HA 64GB DDR5-6400 CL52 ECC Registered 288-pin server RAM

64GB DDR5-6400 registered ECC server memory

This 64GB DDR5 kit contains eight 8GB modules running at 6400 MT/s with CL52 latency. Registered signal processing and on-die ECC protect data integrity in multi-socket servers and workstations. The 1.10V operating voltage matches the DDR5 baseline for dense configurations. Modules use Hynix 2Rx4 ICs on standard 288-pin DIMM PCBs.

Thermals and power at 1.10V

Registered buffering and the low 1.10V rail keep per-module power modest even with eight ranks populated. Passive operation is typical in chassis with directed airflow; no heat spreaders are fitted. The tRAC of 32ns and 52-52-52 timings indicate standard JEDEC DDR5-6400 behaviour under sustained server loads.

What the registered ECC design changes

Registered clock drivers reduce electrical load on the memory controller, allowing all eight DIMM slots to be filled without signal degradation. On-die ECC corrects single-bit errors inside each DRAM chip before data leaves the module. The combination targets uptime-critical workloads rather than low-latency desktop or overclocking use.
