Target system and kit contents

This 512GB kit contains four 128GB DDR5 ECC registered DIMMs built for the ASUS RS720Q-E11-RS8U 2U4N high-density server. It is intended for administrators scaling memory capacity in that specific platform.

Pre-installation checks

Verify that each node in the RS720Q-E11-RS8U supports 4Rx4 registered modules at DDR5 4800 and 1.1V operation. Confirm the motherboard has four free 288-pin slots per node and that the BIOS revision lists this part number as qualified.

What the kit changes

Adding the four modules populates a full channel set with 512GB of ECC registered memory, enabling the server to handle larger virtualization workloads and data-intensive applications. The registered design and ECC function maintain signal integrity and data accuracy under sustained load.
