1 TB DDR5 ECC RDIMM kit

This kit delivers 1 TB of DDR5 4800 registered ECC memory in eight 128 GB modules. It is built for the ASUS RS520A-E12-RS12U single-socket 2U server and targets administrators who need maximum capacity in that platform.

Capacity and headroom at CL40

Eight 4Rx4 modules provide dense capacity for virtualization, databases and large datasets. The CL40 latency and 1.1 V operation suit sustained server workloads, while the registered design supports signal integrity at full population.

Kit contents simplify deployment

The package supplies all eight matched modules in a single kit, removing the need to source individual sticks and reducing the risk of mixing revisions during installation.
