ASUS 2U4N RS720Q-E11-IM Compatible Kit

This NEMIX RAM kit provides 384GB of DDR5 4800 memory in six 64GB registered DIMMs. It is built specifically for the ASUS 2U4N RS720Q-E11-IM high-density immersion cooling server. ECC and registered operation protect data integrity in mission-critical workloads.

Six-Module Kit Enables Full Population

The package contains six matched 64GB modules totalling 384GB, allowing you to fill all available slots in supported configurations. Each module runs at 1.1V with CL40 latency and uses a 2Rx4 organisation based on major OEM Samsung, Micron or Hynix components. No heat spreaders are fitted, which suits the immersion cooling design.

Ideal for High-Density Immersion Servers

This kit suits administrators deploying or expanding ASUS 2U4N RS720Q-E11-IM platforms that require maximum registered ECC capacity. Buyers needing non-registered UDIMMs, lower capacities, different form factors or compatibility with other server models should look at something else.

Questions about this item

Will the six 64 GB modules need any active cooling such as heatsinks or fans during continuous operation?

The kit ships without heat spreaders; in a server chassis airflow across the bare PCB is usually sufficient, but verify your ASUS RS720Q-E11-IM cooling design matches the vendor’s immersion-cooling specification.

At DDR5 4800 CL40, what latency or bandwidth ceiling appears first when all 384 GB run sustained workloads?

The registered 2Rx4 organisation and CL40 timing set the latency floor; sustained throughput is bounded by the PC5-38400 data rate and the memory controller’s ability to keep all six channels fed.

How much power and heat does the 1.1 V registered ECC kit generate when the server runs 24/7?

Each 64 GB RDIMM operates at 1.1 V; total draw depends on load and the ASUS platform’s power management, but the low voltage and lack of onboard LEDs keep thermal output modest for immersion-cooled density.
