64GB DDR5 4800 ECC RDIMM module

This 64GB DDR5 4800 ECC RDIMM module is built for the ASUS RS720A-E12-RS12 dual-processor server. It operates at 1.10V with CL40 latency and uses a 2Rx4 registered design. The 288-pin form factor fits the platform's DDR5 slots directly.

Who should use this and who should not

IT teams expanding memory in the named ASUS 2U server will find guaranteed compatibility and ECC data integrity. Builders needing unbuffered UDIMM modules, non-ECC memory, or capacities other than 64GB per stick should look elsewhere.

The specification that decides fit

The module is a 288-pin DDR5 RDIMM with ECC and registered buffering at 4800 MT/s. Only systems that accept this exact combination of pin count, protocol, error correction and registration will recognise and run the memory.
