128 GB DDR5 4800 ECC RDIMM

This NEMIX RAM module provides 128 GB of DDR5 4800 registered ECC memory in a single 288-pin RDIMM. It operates at 1.10 V with CL40 latency and a 4Rx4 rank structure. The module is validated for the ASUS RS700A-E12-RS4U 1U dual-processor server.

Who this suits

IT teams expanding memory capacity in the named ASUS 1U server will find a matched, stress-tested module that supports error correction and registered signalling. Builders using consumer motherboards, non-registered DIMM slots, or systems requiring a different voltage or form factor should look elsewhere.

Deciding specification

The 4Rx4 registered ECC organisation at DDR5 4800 is the single attribute that determines whether this DIMM will function in the target ASUS server; the memory controller must accept 4-rank registered modules at this speed and voltage.

Questions about this item

What motherboard and processor combination is required for this 4800MHz DDR5 ECC RDIMM to operate?

This module is built for the ASUS RS700A-E12-RS4U 1U dual-processor server; the platform must support DDR5 4800 registered ECC memory at 1.1V with a 288-pin RDIMM slot.

How will this 4Rx4 registered DDR5 module behave if I keep older DDR5 RDIMMs of a different rank in the same ASUS server?

Mixing 4Rx4 modules with other ranks or speeds forces the memory controller to run all channels at the lowest common speed and timing; for best stability populate identical 4Rx4 modules in matched channels.

How can I confirm the 128GB module is running at 4800MHz with ECC active after installation?

Enter the server BIOS or use a tool such as dmidecode to verify the reported speed shows 4800 MT/s, the voltage reads 1.1V, and ECC status is enabled for the installed 128GB DIMM.
