Server Memory Kit

This NEMIX RAM kit supplies 128 GB of DDR5 ECC registered memory in a matched pair of 64 GB modules. It is built for IT professionals who manage ASUS dual-socket 2U servers and need validated compatibility for mission-critical workloads. The modules install directly into 288-pin RDIMM slots without additional configuration steps.

Registered ECC DDR5 4800

Each module runs at DDR5 4800 (PC5-38400) with a CAS latency of CL40 and operates at 1.1 V. The 2Rx4 registered design adds a buffer that stabilises signal integrity across fully populated server boards. ECC circuitry corrects single-bit errors to maintain data integrity under sustained load.

Thermals and Power

Bare modules without heat spreaders rely on the server chassis airflow for cooling, which is standard for 2U rack environments. The low 1.1 V operating voltage keeps power draw modest per DIMM, reducing thermal load on the memory subsystem. Silent operation is assured because no active cooling components are attached to the sticks.

Questions about this item

What does the 4800 MT/s speed mean when the modules are installed in the RS720-E11-RS12U?

The kit runs at DDR5 4800 MT/s (PC5-38400) once populated in the server, delivering the rated data rate for each 64 GB module.

How does the 288-pin RDIMM interface limit the memory configuration?

The 288-pin DDR5 RDIMM form factor fits only registered DIMM slots on the ASUS RS720-E11-RS12U motherboard and requires ECC RDIMM support.

What physical space and power do the two 64 GB sticks need to fit the server?

Each module is a standard 288-pin DDR5 RDIMM operating at 1.1 V; the kit occupies two DIMM slots and uses the 2Rx4 rank layout.
