Server memory kit

This 384GB kit supplies twelve 32GB DDR5 4800 CL40 ECC registered DIMMs built for the ASUS RS720A-E12-RS24U 2U dual-processor server. It delivers high-capacity error-correcting memory for mission-critical workloads.

Build integration

The modules operate at 1.10V and use the standard 288-pin RDIMM form factor with 1Rx4 organisation, so they install directly into the server's memory slots without additional cooling hardware. Registered buffering reduces electrical load on the memory controller.

Target fit

Suited for IT teams expanding memory in the named ASUS platform where ECC and registered operation are required. Not suited for desktop boards, consumer workstations or any system that accepts only unbuffered non-ECC DDR5 modules.

Questions about this item

Will the 1.10V operating voltage stay stable under sustained server workloads?

The modules run at 1.10V DDR5 standard voltage. Registered buffering and ECC help maintain signal integrity during continuous operation.

How much heat do 12 registered DIMMs generate when the RS720A-E12-RS24U runs 24/7?

These RDIMMs have no heat spreaders and draw 1.1V each. Airflow across the 288-pin slots is the primary cooling path in the 2U chassis.

Does the ASUS RS720A-E12-RS24U motherboard need a specific BIOS revision before installing this 384GB kit?

The kit is built for the ASUS RS720A-E12-RS24U dual-processor server. Check the ASUS support page for the minimum BIOS version that enables 12 × 32GB DDR5 4800 RDIMMs.
