Compatible Server Memory Upgrade

This module is a 128GB DDR5 4800MHz ECC Registered DIMM built for the ASUS RS700-E11-RS12U 1U dual-socket server. It operates at 1.1V with CL40 latency and uses a 4Rx4 organisation across 288 pins. The part number MR38400-744K1 identifies the exact configuration validated for that platform.

IT Teams Maintaining Qualified Hardware

Administrators who need a single high-density stick to fill a specific slot in the supported chassis will find this module matches the vendor qualification list. Builders assembling a white-box server or populating a different motherboard should verify compatibility before purchase because this part is tailored to one system.

128GB Density in One Slot

The 128GB capacity delivered by a single 288-pin RDIMM is the decisive specification. It lets the RS700-E11-RS12U reach its maximum memory ceiling with fewer occupied slots, which the platform’s memory controller and qualified-vendor list explicitly support.

Questions about this item

How can I confirm the 128GB DDR5 4800 module is running at CL40 1.1V after installing it in my ASUS RS700-E11-RS12U server?

Enter the BIOS on boot and verify the memory information screen shows 4800 MT/s, CAS latency 40 and 1.1 V for the installed DIMM.

What ships in the box and do I need any extra parts to add this 288-pin RDIMM to the RS700-E11-RS12U?

The package contains one 128 GB DDR5 4800 ECC registered RDIMM; no additional components are required for installation.

Which capacity and rank option should I select for the RS700-E11-RS12U if I want a single 4Rx4 module?

Choose the 128 GB 4Rx4 DDR5 4800 CL40 1.1 V RDIMM, part number MR38400-744K1, which matches the server's qualified configuration.
