NEMIX RAM RS720Q-E11-RS8U 512GB (16x32GB) DDR5 4800 CL40 1.1V ECC RDIMM memory upgrade

512GB DDR5 4800 ECC RDIMM kit

This 512GB kit contains sixteen 32GB DDR5 4800 modules built for the ASUS RS720Q-E11-RS8U server. Each module is a 288-pin registered DIMM with on-die ECC and a CL40 latency profile. The 1Rx4 organisation suits high-density configurations in 2U4N chassis. IT teams scaling memory in validated ASUS platforms use this kit.

DDR5 4800 registered interface limits

The DDR5 4800 standard caps transfer rate at 4800 MT/s and operates at 1.10V. Registered buffering adds one clock cycle to command timing, which stabilises heavily loaded channels but reduces raw latency versus unbuffered DIMMs. Maximum capacity per channel depends on the motherboard memory controller, not the modules alone. Systems requiring speeds beyond 4800 MT/s or lower voltages cannot use this kit.

No heat spreader, registered connector

Modules ship without heat spreaders, relying on chassis airflow for cooling in dense 2U4N layouts. The 288-pin RDIMM keying prevents insertion into consumer UDIMM slots. Registered signalling demands a server-class memory controller; desktop or workstation boards without RDIMM support will not post. Buyers needing passive cooling headroom or UDIMM compatibility should choose a different module type.
