Compatible ASUS 1U Server Memory

This 256GB kit contains eight 32GB DDR5 4800 ECC RDIMM modules built for the ASUS RS700-E11-RS12U 1U dual-socket server. Registered buffering and on-die ECC protect data integrity in mission-critical workloads. Each module runs at 1.1V with CL40 latency and a 1Rx4 organisation. The kit arrives as a matched set validated for that specific platform.

Suited for capacity-bound server tasks

IT teams expanding memory in the named ASUS 1U chassis will find the correct form factor, voltage and registration pre-verified. Systems that require unbuffered DIMMs, non-ECC memory or a different pin count cannot use this kit. Builders targeting consumer motherboards, laptops or workstations without registered DIMM support should select another product.

DDR5 4800 ECC RDIMM specification

The decisive attribute is the DDR5 4800 registered ECC RDIMM standard with 288 pins and 1.1V operation. Only platforms that explicitly accept DDR5 RDIMM modules at this speed and voltage will boot correctly with this memory.

Questions about this item

How much power does the 1.10V DDR5 4800 kit draw when the server runs continuously?

Each 32GB module operates at 1.10V, so the eight-module kit runs at standard DDR5 voltage for lower heat output during all-day workloads.

What must the ASUS RS700-E11-RS12U already have for this 256GB kit to function?

The server needs an ASUS RS700-E11-RS12U motherboard with twelve 288-pin DDR5 RDIMM slots and a CPU that supports registered ECC memory.

Will the CL40 1Rx4 modules work alongside any existing DDR5 RDIMM in the same chassis?

Yes, provided the installed modules are also DDR5 4800 registered ECC 1Rx4 RDIMMs; mixing ranks or speeds forces the system to run at the lowest common settings.
