Compatible Server Memory Kit

This 1TB memory kit contains sixteen 64GB DDR5 RDIMM modules built for the ASUS RS720-E11-RS24U 2U dual-socket server. Registered ECC operation protects data integrity in mission-critical workloads. The kit arrives new and ready for installation by IT staff or qualified technicians.

Suitable Use Cases and Limits

The modules suit administrators upgrading the named ASUS platform to its full 1TB capacity with matched 2Rx4 parts. Buyers who need UDIMM form-factor memory or non-ECC modules for workstation boards cannot use this registered server kit. Systems requiring different pin counts, voltages or speeds should select a different product.

Decisive Specification

DDR5 4800 CL40 registered ECC RDIMM at 1.10V in a 288-pin 2Rx4 configuration. This exact combination of speed, latency, registration, voltage and rank organisation determines whether the modules will initialise correctly in the target server.

Questions about this item

How do I install the 288-pin DDR5 RDIMM modules in the RS720-E11-RS24U server, and what step is often missed?

Power down the server, open the chassis, align each module's notch with the slot key, press firmly until the ejector tabs click, then verify all 16 modules are recognised in the BIOS memory map before closing the case.

What maintenance or replacement will this 1 TB DDR5 ECC registered kit need over its service life?

No scheduled maintenance is required; ECC corrects single-bit errors on the fly, and a module is only replaced if the system logs uncorrectable errors or a DIMM fails POST.

What limit appears first when the 16 × 64 GB kit runs at 4800 MT/s CL40 under sustained load?

The 1.10 V operating voltage and registered buffer keep signal integrity within spec, so the practical ceiling is the platform's maximum memory bandwidth rather than thermal or timing headroom.
