1TB DDR5 server memory kit

This 1TB kit contains sixteen 64GB DDR5 4800 registered DIMMs with ECC. The modules run at 1.10V and carry a CL40 latency rating. They are built for the ASUS RS520A-E12-RS24U single-socket 2U server.

Who this suits and who it does not

IT teams expanding the memory of an ASUS RS520A-E12-RS24U will find a matched, tested set. Builders working with other server models or workstations should verify their platform supports 2Rx4 registered DDR5 before purchasing.

The spec that decides fit

Each module is a 288-pin DDR5 RDIMM organised as 2Rx4 with on-die ECC. If the target system requires unbuffered DIMMs, a different rank configuration, or a non-DDR5 generation, this kit will not work.

Questions about this item

How do I verify the 1TB kit is running at DDR5 4800 CL40 after installation?

Check the BIOS or UEFI memory information screen; it should report 4800 MT/s speed and CL40 latency for the 16 modules.

What comes in the package and do I need extra parts for the ASUS RS520A-E12-RS24U?

The box contains sixteen 64 GB DDR5 4800 ECC registered RDIMMs; no additional components are required for the compatible ASUS server.

Should I choose this 1TB (16×64 GB) kit or a smaller capacity for the RS520A-E12-RS24U?

Select the 1TB kit when the workload demands maximum registered ECC capacity across all sixteen slots.
