System-specific DDR5 kit

This 32 GB kit contains two 16 GB DDR5 4800 CL40 ECC registered DIMMs built for the ASUS RS720-E11-RS12U 2U dual-socket server. It targets administrators who need validated, registered memory with error correction for mission-critical workloads.

Thermals power and noise

The modules run at 1.10 V without heat spreaders, relying on the server’s directed airflow for cooling. Registered buffering and ECC add minimal latency overhead while maintaining signal integrity under sustained load in a 2U chassis.

Build integration

Each 288-pin RDIMM is a 1Rx8 design that fits the motherboard’s DDR5 slots exactly as specified by the vendor qualification list. The kit frees administrators from mixing vendors and ensures the memory subsystem meets the platform’s registered ECC requirements.

Questions about this item

How do I install the 288-pin DDR5 RDIMM modules in the ASUS RS720-E11-RS12U server?

Power down the server, open the chassis, locate the memory slots for the RS720-E11-RS12U motherboard, align the notch on each 288-pin DDR5 RDIMM with the slot key, press firmly until the retention clips lock, then close the chassis and power on.

What maintenance or replacement will the ECC RDIMM kit need later?

The modules have no heat spreader and require no periodic maintenance; if a module fails, the lifetime replacement warranty covers a direct swap of the defective 16 GB stick.

What limit appears first under sustained load with the CL40 1.1 V DDR5 4800 registered memory?

The registered buffer adds one cycle of latency, so the CL40 timing at 1.1 V becomes the primary bottleneck during continuous heavy workloads.
