128 GB DDR5 RDIMM for SuperMicro X13

This 128 GB DDR5 4800 registered DIMM targets server and workstation builders who need maximum capacity in a single slot on SuperMicro X13SET-G or X13SET-GC platforms. The module delivers ECC protection and registered signalling for data integrity in mission-critical environments.

Capacity headroom and limits

One module provides 128 GB at DDR5 4800 (PC5-38400) with CL40 latency and 1.1 V operation, using a 4Rx4 organisation across 288 pins. The single-slot design leaves remaining DIMM sockets free for future expansion, while the quad-rank layout may restrict maximum total capacity on boards that limit rank count per channel.

Build integration requirements

Installation requires a motherboard that supports DDR5 RDIMM ECC memory and the specific SuperMicro X13SET-G or X13SET-GC models listed. The module has no heat spreader, so airflow across the DIMM slots must be adequate for sustained server workloads. Registered signalling and ECC function only with compatible chipset and BIOS support.

Questions about this item

Will this 4Rx4 DDR5 4800 module work with the existing memory already installed in my SuperMicro X13SET-G or X13SET-GC?

The module is designed for the SuperMicro X13SET-G and X13SET-GC platforms; consult the motherboard manual for supported rank and capacity configurations before mixing with other DIMMs.

How can I verify the 128 GB DDR5 4800 CL40 ECC RDIMM is running correctly after installation?

Enter the system BIOS or UEFI and confirm the installed memory reports 128 GB at 4800 MT/s with ECC active, then run a memory stress utility to validate stability.

What is included in the package and do I need any extra parts to install this 288-pin RDIMM?

The package contains one 128 GB DDR5 4800 CL40 1.1 V 4Rx4 ECC registered DIMM; no additional components are required for installation in a compatible SuperMicro motherboard.
