Server memory kit

This kit provides 768GB of DDR5 registered ECC memory across six 128GB modules. It runs at 4800MHz with CL40 latency and operates at 1.1V. The 288-pin RDIMM form factor is built for the ASUS RS720A-E12-RS24U dual-processor 2U server.

Compatibility and limits

Suits administrators expanding that specific ASUS server to its supported memory capacity. Not for workstations or desktops that use unbuffered DIMMs, nor for any system that cannot accept registered ECC modules. Buyers needing a different capacity or a different server platform should verify their motherboard qualification list first.

Decisive specification

The 4Rx4 rank organisation and registered ECC design are the single factors that determine whether this kit will post in the target server. If the motherboard memory controller does not support quad-rank registered DDR5 at 4800MHz, the modules will not function.

Questions about this item

Does this kit use the standard 288-pin DDR5 RDIMM form factor for the ASUS RS720A-E12-RS24U server?

Yes, each of the six modules is a 288-pin DDR5 RDIMM measuring the standard DIMM length and keyed for DDR5 server boards.

What is the correct population order for the six 128 GB modules in a dual-processor ASUS RS720A-E12-RS24U?

Fill the six slots belonging to the first CPU before adding any to the second CPU; the motherboard manual lists the exact slot numbers for each channel.

When should the 4Rx4 registered ECC modules be replaced in a 24/7 ASUS RS720A-E12-RS24U deployment?

Replace them if the system logs show rising correctable ECC errors, if memory diagnostics report failures, or after a major platform upgrade that requires different speed or capacity.
