Server DDR5 ECC RDIMM

This 128GB DDR5 module is built for the ASUS RS520A-E12-RS12U single-socket 2U server. It delivers registered ECC memory for IT professionals who need reliable capacity in a mission-critical environment.

4Rx4 registered organisation

The module uses a 4Rx4 configuration with CL40 latency at 4800 MT/s. This specific rank and buffer arrangement is the single specification that determines whether the server will recognise and stabilise the full 128GB capacity.

Single-module upgrade kit

The package contains one 288-pin RDIMM running at 1.10V with Samsung, Micron or Hynix chips. No heat spreader is included, so airflow in the 2U chassis must handle thermal management directly.

Questions about this item

What does the 4800 speed rating mean when the module is installed in an ASUS RS520A-E12-RS12U server?

The module runs at DDR5 4800 MT/s, delivering PC5-38400 bandwidth in the server's memory controller.

How does the 288-pin DDR5 RDIMM interface limit performance in this system?

The registered DDR5 interface caps the module at 4800 MT/s and requires the server's memory controller to support ECC registered DIMMs.

Will the 4Rx4 128 GB stick fit the memory slots in an ASUS RS520A-E12-RS12U 2U chassis?

Yes, the 288-pin DDR5 RDIMM form factor matches the server's DIMM slots and the single-module design occupies one slot.
