System-specific DDR5 server memory

This 128GB kit contains four 32GB DDR5 4800 ECC RDIMM modules built for the ASUS RS720-E11-RS12U 2U dual-socket server. Each stick runs at 1.1V with CL40 latency and uses a 1Rx4 registered design for signal integrity. The modules are validated for compatibility with that specific server model.

Suits administrators upgrading that exact ASUS

Buyers who need a different capacity, speed or form factor should look elsewhere because this kit is tailored to one server model. Systems that require unbuffered UDIMMs or non-ECC memory cannot use these registered ECC modules.

DDR5 4800 PC5-38400 registered ECC specification

The decisive figure is the DDR5 4800 (PC5-38400) registered ECC RDIMM standard with 1Rx4 organisation and 1.1V operation. Only platforms that explicitly support this exact memory type will accept the kit.
