512GB DDR5 4800 ECC RDIMM Kit

This NEMIX RAM kit delivers 512GB of DDR5 4800 memory using sixteen 32GB registered DIMMs. Each module runs at 1.1V with CL40 latency and includes on-die ECC for data integrity. The 288-pin RDIMM form factor is built for the ASUS RS720-E11-RS12U 2U dual-socket server.

Ideal for IT teams scaling memory in that specific

The registered 1Rx4 design suits workloads needing maximum capacity per channel. Buyers who need unbuffered UDIMMs, lower-density 16GB modules, or memory for a different server chassis should look elsewhere.

DDR5 4800 registered ECC with 1Rx4 organisation

The single-rank-by-four architecture determines how the memory controller addresses each 32GB module. Confirm the RS720-E11-RS12U motherboard supports sixteen 1Rx4 RDIMMs at 4800MT/s before ordering.

Questions about this item

Will these 288-pin DDR5 RDIMM modules fit the memory slots on my ASUS RS720-E11-RS12U 2U server?

Yes, the kit is built specifically for the ASUS RS720-E11-RS12U dual-socket 2U server and uses the 288-pin DDR5 RDIMM form factor that matches the board's DIMM slots.

What is the correct population order for the 16 modules across the two CPU sockets?

Populate all eight channels per socket evenly; install one 32 GB 1Rx4 RDIMM per channel before adding a second rank, following the slot sequence shown in the ASUS RS720-E11-RS12U service manual.

When should I expect to replace a module if ECC starts logging correctable errors?

The modules carry a lifetime replacement warranty; if the server's ECC reporting shows rising correctable-error counts on any of the 16 sticks, request a replacement for that specific module.
