Capacity and Compatibility

This 1 TB kit contains sixteen 64 GB DDR5 RDIMM modules built for the ASUS RS720Q-E11-RS8U 2U4N high-density server. Registered ECC operation protects data integrity in mission-critical workloads. It targets IT teams who need a single validated part number for maximum density.

Thermals and Power

Each module runs at 1.1 V with no heat spreader, relying on the server’s directed airflow for cooling. Registered buffering reduces electrical load on the memory controller during sustained throughput. CL40 latency at 4800 MT/s balances bandwidth and stability for dense configurations.

Package and Validation

The box delivers the full 1 TB as a matched 16-module set, eliminating mixed-rank uncertainty. Every stick undergoes stress testing under load before shipment to verify compatibility with the target platform. No additional software or accessories are included.

Questions about this item

How do I install the 16 DDR5 288-pin RDIMM modules into the ASUS RS720Q-E11-RS8U server?

Power down the server, open the chassis, locate the 16 DIMM slots per node, align each module's notch with the slot key, press firmly until both retention clips click, then close the chassis and power on to verify 1TB detected.

What maintenance will the 16x64GB DDR5 ECC registered kit need over its service life?

No routine maintenance is required; the modules have no heat spreaders or moving parts. If a module fails, replace the individual 64GB RDIMM — ECC corrects single-bit errors on the fly.

At what point does the CL40 1.10V DDR5 4800 kit hit its thermal or bandwidth limit under sustained load?

The first limit is the DDR5 4800 MT/s data rate; sustained workloads saturate the PC5-38400 bandwidth ceiling before the 1.10V modules reach thermal throttling thresholds.
