Compatible server memory kit

This 2 TB kit contains sixteen 128 GB DDR5 registered DIMMs built for the ASUS RS720-E11-RS24U 2U dual-socket server. ECC and registered operation protect data integrity in mission-critical workloads. The modules run at 4800 MT/s with CL40 latency at 1.1 V. No heat spreaders are fitted.

Who should use this kit

IT teams upgrading the named ASUS server to its maximum supported capacity will find a matched, stress-tested set ready for immediate installation. Builders working on other platforms, smaller configurations or non-ECC systems should look elsewhere.

Deciding specification

The kit delivers 2 TB total capacity across sixteen 288-pin DDR5 RDIMMs. This single figure determines whether the upgrade fits the target server's memory slots and density limits.

Questions about this item

Will the 4800 CL40 modules run at rated speed if I keep my existing DDR5 DIMMs in the RS720-E11-RS24U?

The kit is validated for the ASUS RS720-E11-RS24U at DDR5 4800 CL40 1.1 V; mixing with other DDR5 modules may force the system to run at the lowest common speed and latency.

How can I confirm the 2 TB kit is detected and ECC is active after installation?

Enter the BIOS or use a tool such as dmidecode to verify all 16 modules show 128 GB each at 4800 MT/s and that ECC status reads enabled.

Does the package include anything besides the 16 registered DIMMs?

The box contains only the 16 x 128 GB DDR5 4800 CL40 288-pin ECC RDIMMs; no heat spreaders, cables or additional accessories are supplied.
