512GB DDR5 ECC RDIMM kit

This 512GB kit contains four 128GB DDR5 4800MHz ECC registered DIMMs built for the ASUS RS700-E11-RS4U 1U dual-socket server. Each module runs at 1.1V with CL40 latency and a 4Rx4 organisation using major OEM DRAM. The registered design buffers address and command signals to maintain stability across all populated slots.

Suited for memory-heavy server workloads

IT teams expanding virtualisation hosts, in-memory databases or high-thread-count compute nodes on the qualified ASUS platform will gain immediate capacity headroom. Builders using consumer motherboards, workstations without registered DIMM support, or systems limited to lower maximum densities should select different memory.

Registered ECC DDR5 at 4800MHz

The single specification that decides fit is the registered ECC DDR5 4800MHz RDIMM form factor required by the ASUS RS700-E11-RS4U. Only modules matching this exact type, voltage and pin count will be recognised and operate reliably in the target server.

Questions about this item

How much power does the 512GB DDR5 4800MHz CL40 kit draw at 1.1V during sustained server workloads?

Each 128GB module operates at 1.10V; the four-module kit runs at standard DDR5 voltage for registered ECC memory.

Does the ASUS RS700-E11-RS4U motherboard require a specific BIOS revision or CPU generation to recognise 4Rx4 registered DIMMs?

The kit is validated for the ASUS RS700-E11-RS4U 1U dual-socket server; consult the system manual for supported processor and BIOS combinations.

Can the 288-pin RDIMMs be mixed with existing lower-capacity DDR5 registered modules in the same server?

All four slots are populated with matched 128GB 4Rx4 modules; mixing ranks or capacities is not recommended for this validated configuration.
