Dell PowerEdge XE9680 memory upgrade

This 128GB DDR5 module is built for the Dell PowerEdge XE9680 rack server. It delivers registered ECC memory for enterprise workloads that demand data integrity. The single-module design lets administrators add capacity one slot at a time.

128GB capacity with 4Rx4 organisation

The quad-rank layout packs 128GB into one 288-pin slot, maximising density for virtualisation and large datasets. Four ranks per channel increase electrical loading, so total system capacity depends on the platform's rank limits per memory controller.

1.1V operation at DDR5 4800

Standard DDR5 voltage keeps power draw low while running at 4800 MT/s. No heat spreader is fitted, so airflow across the module must be sufficient for sustained server loads.

Questions about this item

Will the 4Rx4 rank layout of this 128GB DDR5 4800 module work alongside my existing 2Rx4 sticks in the Dell PowerEdge XE9680?

The 4Rx4 organization is fully supported by the XE9680 memory controller; populate each channel according to the server's DIMM population rules and the system will recognise the total capacity.

How can I verify the module is running at DDR5 4800 CL40 1.10V with ECC active after installation?

Enter the iDRAC or BIOS memory configuration screen — it will show each DIMM at 4800 MT/s, CAS 40, 1.10 V and ECC enabled when the module is operating correctly.

Does the package include only the 288-pin RDIMM or are any rails or cables supplied?

The box contains the single 128GB 288-pin DDR5 RDIMM; no rails, cables or additional hardware are included.
