Capacity and kit layout

This kit provides 64GB of DDR5 memory across two 32GB registered DIMMs. It is built for the ASUS RS700A-E12-RS12U dual-processor server where ECC and registered signalling are required for stable operation.

DDR5 4800 interface and headroom

Running at 4800MT/s with CL40 latency and 1.10V, the modules deliver PC5-38400 bandwidth suitable for virtualisation and database workloads. The 1Rx4 organisation keeps electrical loading low, but capacity stops at 64GB so larger datasets will need additional DIMM slots or a higher-density kit.

Registered ECC constraints

The 288-pin RDIMM form factor fits only slots wired for registered ECC DDR5; it will not work in unbuffered desktop or laptop sockets. ECC correction protects data integrity, yet the fixed CL40 timing and single-voltage design leave no headroom for manual overclocking or voltage tuning.

Questions about this item

Will these DDR5 4800 ECC RDIMM modules work in my ASUS RS700A-E12-RS12U alongside existing DDR5 4800 registered memory?

Yes, they are built for that server and run at DDR5 4800 with CL40 timing, so they match the speed and registered design of other DDR5 4800 ECC RDIMMs already installed.

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

Check the BIOS memory information or use a tool like dmidecode; it should show 4800 MT/s, CL40, 1.10 V and ECC enabled for each 32 GB module.

What comes in the box and do I need any extra parts to install the 64 GB kit?

The package contains two 32 GB 288-pin DDR5 ECC RDIMMs; no additional hardware is required for installation in the compatible ASUS server.
