High-Density Server Memory Upgrade

This 128GB DDR5 RDIMM is built for the ASUS RS720Q-E11-RS8U 2U4N high-density server platform. It targets IT professionals who need maximum memory capacity per slot in multi-node environments. The registered ECC design supports data integrity for mission-critical workloads. Single-module population simplifies density scaling across the chassis.

DDR5 4800 Registered Interface Limits

The module operates at DDR5 4800 (PC5-38400) with a CL40 latency profile at 1.10V. Registered buffering adds one clock cycle to command timing, which is standard for load-reduced server topologies. Four-rank 4Rx4 organisation increases electrical loading on the memory bus, so maximum supported DIMMs per channel depends on the platform memory controller. Mixed-rank populations may reduce achievable speeds below the rated 4800 MT/s.

288-Pin RDIMM Build and Daily Handling

The bare 288-pin PCB has no heat spreader, relying on directed chassis airflow for thermal management. Gold edge contacts are rated for repeated insertion cycles during maintenance windows. ECC and registered circuitry add component height, so verify cooler clearance in dense 2U nodes before installation. Single 128GB stick per package means upgrades proceed one node at a time without splitting kits.

Questions about this item

Should I choose the single 128GB module or look for a kit of smaller modules?

This listing is a single 128GB DDR5 4800 CL40 4Rx4 ECC RDIMM. Populate each channel with one module to reach the rated speed.

What does the 4800 MT/s rating deliver once installed in the ASUS RS720Q-E11-RS8U server?

The module runs at DDR5 4800 (PC5-38400) with CL40 latency at 1.1V, providing the maximum JEDEC standard bandwidth the platform supports.

How does the 288-pin DDR5 RDIMM interface limit performance in this 2U4N server?

The registered 288-pin DDR5 interface caps operation at 4800 MT/s with ECC enabled; the memory controller cannot exceed this data rate.
