Purpose-built server memory kit

This 128GB kit comprises two 64GB DDR5 ECC RDIMM modules built for the ASUS RS720Q-E11-RS8U 2U4N high-density server. Registered buffering and on-die ECC protect data integrity in mission-critical workloads. The kit targets IT teams upgrading memory capacity in compatible ASUS server platforms.

Registered DDR5 build with standard server pinout

Each module uses a 288-pin RDIMM form factor and operates at 1.1V with CL40 latency at 4800 MT/s. Major OEM DRAM from Samsung, Micron or Hynix underpins the 2Rx4 organisation. No heat spreader is fitted, so airflow in the server chassis must be sufficient for bare modules.

Verify motherboard slot population rules before

Confirm the RS720Q-E11-RS8U motherboard supports 64GB RDIMM density per slot and the desired total capacity per node. Check BIOS revision requirements for DDR5 4800 registered ECC modules. Ensure the 2U4N chassis provides adequate airflow for modules without heat spreaders.

Questions about this item

Does this kit use the DDR5 4800 (PC5-38400) interface and what bandwidth does it provide?

The kit is DDR5 4800 (PC5-38400) registered ECC RDIMM; bandwidth per module is determined by the platform's memory controller and channel configuration.

Will these 288-pin 2Rx4 RDIMMs fit the ASUS RS720Q-E11-RS8U 2U4N server chassis?

Yes, the 288-pin DDR5 RDIMM form factor matches the motherboard slots; the 2Rx4 organisation is validated for this 2U4N high-density server model.

How do I install the two 64 GB modules in the RS720Q-E11-RS8U and what step is often missed?

Power down, open the node, align each 288-pin RDIMM with the slot key, press firmly until both ejector clips lock, then verify in BIOS that all 128 GB are detected at 4800 MT/s.
