Compatible server memory module

This 16GB DDR5 4800 CL40 ECC RDIMM is built for the ASUS RS720Q-E11-RS8U 2U4N high-density server. It operates at 1.1V with a 1Rx8 layout and 288-pin form factor. Registered buffering and on-die ECC protect data integrity under sustained workloads.

Suited for density-constrained deployments

The single-rank design fits the tight slot spacing of the RS720Q-E11-RS8U chassis while delivering 16GB per module. Systems that require unbuffered UDIMMs, non-ECC memory or speeds above 4800 MT/s cannot use this part.

Registered ECC RDIMM with 1Rx8 organisation

Registered buffering and ECC are mandatory for the target platform; the 1Rx8 rank structure matches the motherboard's memory controller requirements. Verify that your server specifies DDR5 4800 RDIMM support before ordering.

Questions about this item

Should I choose the 16GB module or add multiple units for the RS720Q-E11-RS8U?

Each module provides 16GB capacity. The RS720Q-E11-RS8U is a 2U4N high-density server; total memory depends on how many DIMM slots each node exposes and the maximum per-node limit in the ASUS documentation.

What does the 4800MHz speed deliver in the RS720Q-E11-RS8U server?

The module runs at DDR5 4800 (PC5-38400) with CL40 latency at 1.1V. Actual throughput in the RS720Q-E11-RS8U will match the memory controller's supported data rate and the number of populated channels per node.

Does the 288-pin DDR5 RDIMM interface work directly in the RS720Q-E11-RS8U?

Yes. The module is a 288-pin DDR5 RDIMM with ECC and registered buffering, built to the PC5-38400 standard. It is listed as compatible with the ASUS RS720Q-E11-RS8U 2U4N high-density server.
