64GB DDR5 4800 ECC RDIMM for Dell PowerEdge XE9680

This 64GB registered DIMM delivers ECC protection and 4800 MT/s throughput for the Dell PowerEdge XE9680 rack server. The module operates at 1.1V with CL40 latency and a 2Rx4 organisation. It targets IT teams expanding memory capacity in dense compute nodes.

Sustained throughput with registered ECC

The registered buffer and on-die ECC maintain data integrity during continuous multi-threaded workloads such as virtualisation, database serving and AI training. DDR5 architecture provides higher bandwidth per pin than previous generations while the 1.1V supply keeps power draw in check under prolonged load.

Thermals noise and power in normal operation

Bare modules without heat spreaders rely on chassis airflow for cooling in the XE9680's directed-cooling design. At 1.1V the DRAM runs cool enough for standard server fan curves to remain quiet during typical utilisation. Registered signalling reduces electrical load on the memory controller, helping overall platform power efficiency.
