Targeted server upgrade

This 512GB kit provides eight 64GB DDR5 4800 CL40 ECC registered DIMMs built for the ASUS RS720QA-E12-RS8U 2U4N rack server. It delivers registered error-correcting memory at 1.10V for mission-critical workloads.

Build integration

The modules use the standard 288-pin DDR5 RDIMM form factor and 2Rx4 organisation, so they occupy all available slots in the validated server platform. Registered buffering reduces electrical load on the memory controller, freeing signal integrity for dense multi-node configurations.

Ideal fit and limits

Suited for IT teams expanding memory capacity in the named ASUS high-density rack server 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 CL40 latency become the bottleneck during sustained workloads?

The CL40 latency is the rated timing at DDR5 4800 speed; sustained workloads run at this specification without additional latency penalties.

How much heat and power should I expect from the eight modules running continuously?

Each module operates at 1.10 volts with no heat spreader, so total power draw is low and cooling relies on server chassis airflow over the bare PCBs.

Which server chassis and motherboard must I already have for this kit to function?

The kit is validated for the ASUS RS720QA-E12-RS8U 2U4N rack server; the motherboard must provide 288-pin DDR5 RDIMM slots with registered ECC support.
