Registered DDR5 ECC server memory kit

This 64GB kit contains four 16GB DDR5 4800 RDIMM modules rated at CL40 and 1.1V. The modules are registered with on-die ECC and use a 1Rx8 organisation. They are validated for the ASUS RS720-E11-RS24U 2U dual-socket server.

Who this suits and who should look elsewhere

IT teams upgrading or populating the named ASUS 2U platform with qualified registered ECC memory will find a direct match. Buyers needing unbuffered UDIMMs, non-ECC modules, different capacities, speeds, voltages or form factors, or memory for any other server or workstation model, should look elsewhere.

The specification that decides fit

The kit is a 4x16GB DDR5 4800 CL40 1.1V 288-pin registered ECC RDIMM set qualified for the ASUS RS720-E11-RS24U; only systems that accept this exact registered DDR5 ECC configuration can use it.

Questions about this item

Will the DDR5 4800 CL40 288-pin RDIMM kit run in the ASUS RS720-E11-RS24U alongside existing DDR5 4800 registered modules?

The kit is built for the ASUS RS720-E11-RS24U 2U dual-socket server and matches its DDR5 4800 PC5-38400 1.10V CL40 288-pin RDIMM specification. Mixing ranks or vendors can work but the motherboard manual should be checked for population rules.

How can I confirm the 64 GB kit is detected at 4800 MT/s with ECC active after installation?

Enter the BIOS or UEFI and verify the memory speed reads 4800 MT/s, total capacity shows 64 GB, and ECC status is reported as enabled or active.

Does the package contain only the four 16 GB RDIMMs or are any cables, brackets or tools included?

The box holds the 64 GB (4 x 16 GB) DDR5 4800 CL40 1.10V 288-pin ECC RDIMM modules only; no cables, brackets or installation tools are supplied.
