Purpose-Built Server Memory Kit

This 512 GB kit contains eight 64 GB DDR5 registered DIMMs built for the ASUS RS720Q-E11-RS8U 2U4N high-density server. Error-correcting code and registered buffering protect data integrity in mission-critical workloads. The modules run at 1.1 V and fit 288-pin DDR5 slots without heat spreaders. IT teams can install the matched set in minutes to expand memory capacity.

Capacity and Headroom

Eight dual-rank 2Rx4 modules deliver 512 GB total, letting the server host large virtualisation clusters, in-memory databases or heavy container fleets. DDR5 4800 (PC5-38400) bandwidth feeds many cores simultaneously, while CL40 latency keeps response times predictable. The kit fills every DIMM slot in the supported platform, so further expansion requires a chassis with additional memory channels.

Compatibility Decider

The kit is validated only for the ASUS RS720Q-E11-RS8U server model; other boards — even those with DDR5 slots — may not recognise the registered ECC modules or the 2Rx4 organisation. Buyers must confirm their system matches this exact model before ordering.

Questions about this item

Will the 8x64 GB DDR5 4800 CL40 RDIMM kit run correctly with the existing 64 GB modules already in my ASUS RS720Q-E11-RS8U server?

The kit is validated for the ASUS RS720Q-E11-RS8U platform at DDR5 4800 CL40 with 2Rx4 organisation and 1.10 V registered ECC; mixing with other modules of identical speed, rank, voltage and ECC type is supported by the motherboard memory controller.

How can I confirm the 512 GB kit is operating at the rated 4800 MT/s CL40 after installation?

Enter the server BIOS or use a hardware-information utility; the memory summary should show all eight slots populated at 4800 MT/s with CAS latency 40 and registered ECC status active.

Does the package include only the eight 64 GB DDR5 RDIMMs or are any additional parts such as heat spreaders or cables supplied?

The box contains the 512 GB kit of eight 64 GB 288-pin DDR5 4800 CL40 2Rx4 1.10 V registered ECC RDIMMs; no heat spreaders, cables or other accessories are included.
