64GB DDR5 ECC RDIMM kit

This 64GB kit contains four 16GB DDR5 4800 registered DIMMs with ECC and a CL40 latency. The modules operate at 1.1V and use a 288-pin form factor. They are built for the ASUS RS720-E11-RS12U 2U dual-socket server.

Who this suits and who should look elsewhere

This memory suits administrators upgrading or repairing the specified ASUS server where registered ECC DDR5 is required. It is not for desktop PCs, laptops, or workstations that need unbuffered non-ECC memory. Buyers needing different capacities, speeds, or form factors should look elsewhere.

The specification that decides fit

The kit must match the ASUS RS720-E11-RS12U qualified vendor list for DDR5 4800 registered ECC RDIMMs. Verify the server's memory population rules and maximum supported capacity before purchase.
