Capacity and Purpose

This kit provides 2TB of DDR5 4800 registered ECC memory across sixteen 128GB modules. It is built for the ASUS RS700-E11-RS4U 1U dual-socket server and targets IT teams running memory-intensive workloads such as virtualization, databases or high-performance computing.

Compatibility Check

Verify that the server model is exactly RS700-E11-RS4U and that the motherboard accepts 288-pin DDR5 RDIMMs with 4Rx4 organisation at 1.1V. Confirm the BIOS version supports the full 2TB population and that all sixteen DIMM slots are free for this kit.

Build and Connectors

Modules use a bare 288-pin DDR5 RDIMM form factor without heat spreaders, relying on the server’s directed airflow for cooling. Registered signalling and on-die ECC protect data integrity under sustained load, while the 1.1V operating voltage matches the platform’s power envelope for dense 1U deployments.
