Purpose-built server kit

This NEMIX RAM kit delivers 128GB of DDR5 ECC registered memory across eight 16GB modules. It is engineered specifically for the ASUS RS700-E11-RS4U 1U dual-socket server. The registered design and on-die ECC protect data integrity in mission-critical workloads.

Compatibility focus

IT teams running the listed ASUS 1U platform gain a validated, stress-tested population that installs in minutes. Builders targeting other chassis, workstation boards, or consumer desktops should look elsewhere because the kit is qualified only for this specific server model.

Decisive specification

The kit operates at DDR5 4800 with CL40 latency at 1.10V using 1Rx8 registered chips. This speed, voltage, and rank combination determines whether the memory matches the server’s qualified vendor list.

Questions about this item

Does this 288-pin DDR5 RDIMM kit fit the ASUS RS700-E11-RS4U 1U dual-socket server?

Yes, the 128GB kit of eight 16GB modules is built for that exact ASUS 1U dual-socket server model.

What is the correct installation sequence for the eight 1Rx8 registered DIMMs?

Follow the motherboard manual to populate all eight slots in the prescribed channel order; the common error is skipping the per-channel sequence.

When should the 1.10V ECC RDIMMs be checked or replaced?

Run a memory diagnostic at first boot and after any firmware update; replace modules only if errors appear or capacity needs change.
