512GB DDR5 4800 ECC RDIMM kit

This 512GB kit contains eight 64GB DDR5 4800 ECC registered DIMMs built for the ASUS RS720-E11-RS12U 2U dual-socket server. Each module runs at 1.1V with a CAS latency of CL40 and uses a 2Rx4 organisation. The registered design adds a buffer that helps the memory controller manage heavy loads in multi-processor configurations.

Who this suits and who should look elsewhere

IT teams expanding the ASUS RS720-E11-RS12U to its full memory capacity will find a matched, stress-tested set that installs without extra configuration. Builders working with different server platforms, workstations that require unbuffered DIMMs, or systems limited to lower densities should select memory qualified for those specific models.

The specification that decides fit

The kit is qualified only for the ASUS RS720-E11-RS12U server and uses 288-pin DDR5 RDIMMs with ECC and registered signalling; any other platform or DIMM type will not be compatible.

Questions about this item

How much power does the 1.10V DDR5 4800 kit draw when the ASUS RS720-E11-RS12U server runs continuously?

Each 64GB module operates at 1.10V; total draw depends on how many of the eight DIMM slots are populated and the CPU memory controller load.

What must the ASUS RS720-E11-RS12U motherboard already support for this 512GB kit to function?

The board needs eight 288-pin DDR5 RDIMM slots, registered ECC support, and a BIOS that recognises 2Rx4 64GB modules at 4800 MT/s.

Can I mix these CL40 2Rx4 modules with older DDR5 RDIMMs that have different latency or rank?

Mixing different CAS latencies or ranks in the same channel is not recommended; populate all eight slots with identical modules for stable operation.
