ASUS 1U dual-processor server upgrade

This 256GB kit is built for the ASUS RS700A-E12-RS12U 1U dual-processor server. It contains eight registered DDR5 ECC RDIMM modules that install directly into the system board. IT teams use it to expand memory capacity in dense rack deployments.

256GB DDR5 4800 CL40 capacity

Eight 32GB 1Rx4 modules deliver 256GB at 4800 MT/s with CL40 latency. Registered buffering and ECC protect data integrity under sustained server workloads. The kit fills all slots for maximum density in this platform.

1.10V operation without heat spreaders

Modules run at the standard 1.10V DDR5 voltage and have no integrated heat spreaders. They rely on the server's directed airflow for cooling in the 1U chassis. Power draw scales with the fully populated configuration.

Questions about this item

Will the eight 32 GB DDR5 4800 CL40 RDIMMs run alongside older DDR5 modules I keep in the ASUS RS700A-E12-RS12U?

Mixing modules is possible when speed, voltage, rank and ECC type match; this kit uses 1.10 V, CL40, 1Rx4 registered DDR5, so any retained DIMMs must share those exact specifications to avoid instability.

How can I confirm the 256 GB kit is operating at DDR5 4800 with ECC active after installation?

Enter the server BIOS or UEFI and verify the memory frequency reads 4800 MT/s, total capacity shows 256 GB, and ECC status reports enabled or active for all eight slots.

What ships in the box and what must I source separately for the RS700A-E12-RS12U upgrade?

The package contains eight 32 GB 288-pin DDR5 4800 CL40 1.10 V ECC registered RDIMMs; no heat spreaders, cables, tools or additional hardware are included.
