768GB DDR5-4800 ECC RDIMM kit

This 12-module kit delivers 768GB of DDR5-4800 registered ECC memory. Each module is a 64GB 2Rx4 288-pin RDIMM operating at 1.1V with CL40 latency. The kit is validated for the ASUS RS720A-E12-RS12 2U dual-processor server.

Suited for memory-bound server workloads

IT teams running virtualisation, in-memory databases or large-scale analytics on the RS720A-E12-RS12 will benefit from the full 12-slot population. Builders needing non-ECC memory, lower capacities, or modules for a different server platform should look elsewhere.

12 x 64GB registered ECC population

The kit fills all twelve DIMM slots with matched 64GB registered ECC modules. This specific population determines whether the server can reach its maximum supported memory configuration.
