Capacity and Compatibility

This 1.5TB kit contains 12 modules of 128GB DDR5 4800 ECC RDIMM memory. It is built for the ASUS RS720-E11-RS24U 2U dual-socket server. Registered buffering and error correction suit mission-critical workloads that demand data integrity.

Sustained Load Behaviour

Registered modules reduce electrical load on the memory controller during continuous operation. ECC detects and corrects single-bit errors in real time, preventing silent data corruption under heavy throughput. The 1.1V operating voltage helps limit thermal output when all 12 slots are populated.

Build and Connectors

Each module uses a 288-pin DDR5 RDIMM form factor with a 4Rx4 organisation. No heat spreader is fitted, so airflow across the PCB must be managed by the server chassis. The kit arrives as a matched 12-piece set for direct installation into the qualified platform.

Questions about this item

How much power does the 1.1V DDR5 4800 kit draw when the server runs continuously?

Each module operates at 1.1V, the standard DDR5 voltage, so total draw depends on how many of the twelve 128GB RDIMMs are populated and the workload intensity.

What must the ASUS RS720-E11-RS24U already have for this 1.5TB kit to function?

The motherboard needs twelve free 288-pin DDR5 RDIMM slots and a CPU that supports 4Rx4 registered ECC memory at 4800 MT/s.

Can I keep my existing DDR5 4800 RDIMMs and add this 12-module kit alongside them?

Only if the empty slots match the 288-pin RDIMM layout and the memory controller can address the combined rank count without exceeding its limit.
