Compatible ASUS 2U dual-processor server

This 64GB DDR5 4800 ECC RDIMM kit is built for the ASUS RS720A-E12-RS24U server model. It contains two 32GB registered modules that run at 1.10V with CL40 latency. The memory is validated for system-specific compatibility and mission-critical workloads.

Suited for IT teams upgrading that exact ASUS

Administrators who need guaranteed compatibility and registered ECC reliability for dual-processor deployments will benefit. Builders using other motherboards, desktop chipsets, or non-registered memory architectures should look at something else.

Registered DDR5 4800 with 1Rx4 organisation

The single-rank x4 configuration on 288-pin RDIMMs defines whether this kit matches the server's memory controller requirements. Verify the platform demands registered ECC RDIMMs at this speed and rank structure before purchasing.

Questions about this item

Will the DDR5 4800 ECC RDIMM kit run in an ASUS RS720A-E12-RS24U alongside existing DDR5 modules?

The kit is validated for the ASUS RS720A-E12-RS24U server. Mixing with other DDR5 modules of the same speed, voltage and rank configuration is supported by the platform, but identical part numbers give the most reliable operation.

How can I verify the 64GB DDR5 4800 kit is running at CL40 1.10V after installation?

Enter the system BIOS or use a hardware monitoring tool to confirm the memory reports 4800 MT/s, CL40 timings and 1.10 V on each of the two 32GB RDIMMs.

What is included in the package and what must be purchased separately?

The box contains two 32GB DDR5 4800 ECC RDIMM modules for a total of 64GB. No cables, brackets or additional components are supplied; only compatible DIMM slots in the ASUS RS720A-E12-RS24U are required.
