768GB DDR5 ECC RDIMM kit

This 12-module kit delivers 768GB of DDR5 4800 registered ECC memory for the ASUS RS720-E11-RS24U 2U dual-socket server. Each 64GB module operates at 1.1V with CL40 latency and a 2Rx4 organisation. The 288-pin RDIMM form factor fits the platform's registered DIMM slots.

Sustained load behaviour

Registered buffering and on-die ECC maintain data integrity during continuous enterprise workloads such as virtualisation, database processing and high-performance computing. The 1.1V operating voltage helps limit thermal output when all twelve slots are populated under prolonged utilisation.

DDR5 4800 interface limits

The PC5-38400 standard caps transfer rates at 4800 MT/s per module, so total bandwidth scales with the number of populated channels on the motherboard. CL40 timing sets the minimum latency floor for random access patterns. Registered signalling adds one clock cycle of command delay compared with unbuffered modules.

Questions about this item

How much power does the 12-module kit draw at the rated 1.10 V when the server runs continuously?

Each module operates at 1.10 V; total power depends on the server's memory controller load and cannot be derived from the module voltage alone.

What must the ASUS RS720-E11-RS24U motherboard provide for these modules to function?

The board needs 12 DDR5 RDIMM slots, support for 2Rx4 registered ECC DIMMs at 4800 MT/s, and a BIOS that recognises the 768 GB capacity.

Will the CL40 latency of these DDR5 RDIMMs slow down older DDR5 modules already installed in the server?

The memory controller runs all populated channels at the lowest common speed and latency, so adding CL40 modules will match the tighter timing if slower sticks are present.
