384 GB DDR5 ECC RDIMM kit

This 384 GB kit contains six 64 GB DDR5 4800 registered DIMMs with ECC and a CAS latency of CL40. Modules operate at 1.1 V and use a 288-pin form factor. The memory is built for the ASUS RS720Q-E11-RS8U high-density server platform.

Server administrators needing maximum capacity

The six-module configuration fills every slot in the target chassis, delivering the highest supported density for memory-intensive workloads such as virtualization or in-memory databases. Systems with fewer than six slots or platforms that require unbuffered UDIMMs cannot use this kit.

Registered ECC with 2Rx4 organisation

Each module implements a 2Rx4 rank layout and registered signalling, which the ASUS RS720Q-E11-RS8U memory controller requires for stable operation at full population. Boards that only support single-rank or unbuffered memory will not post with these DIMMs installed.

Questions about this item

Will the 288-pin DDR5 RDIMM modules fit the memory slots in the ASUS RS720Q-E11-RS8U 2U4N server?

Yes, the kit contains six 64 GB modules built to the 288-pin DDR5 RDIMM form factor that matches the server's DIMM sockets.

What is the correct population order for the six 2Rx4 modules when installing them in the RS720Q-E11-RS8U?

Follow the motherboard manual's channel sequence; a common mistake is placing modules in the wrong channel order, which prevents the system from recognising the full 384 GB capacity.

Do the Samsung, Micron or Hynix chips on these RDIMMs require any firmware updates or periodic maintenance?

No firmware updates are needed for the memory itself; keep the server's BIOS current and ensure adequate airflow so the modules stay within their 1.10 V operating envelope.
