Server memory kit

This 2 TB kit contains sixteen 128 GB DDR5 modules built for the Dell PowerEdge XE9680. Each module runs at 4800 MT/s with CL40 latency and operates at 1.1 V. The registered ECC design targets enterprise workloads that require data integrity.

Sustained workload behaviour

Registered buffering and on-die ECC keep signal quality stable during long compute runs across all sixteen slots. The 4Rx4 organisation spreads address load evenly so bandwidth remains consistent under heavy memory pressure. Modules are stress tested under load before shipment to confirm reliability.

Thermals and power

Bare modules without heat spreaders rely on the server’s directed airflow for cooling. At 1.1 V the kit draws minimal power per DIMM while delivering 38 400 MB/s peak throughput per module. No active cooling components are included in the package.

Questions about this item

How much power do the 1.1 V DDR5 4800 modules draw when the server runs continuously?

Each module operates at 1.1 V, the standard DDR5 voltage, so total power scales with the 16 modules installed and the workload on the Dell PowerEdge XE9680.

What must the Dell PowerEdge XE9680 already have to accept these 288-pin RDIMMs?

The server needs DDR5 RDIMM slots that support 4Rx4 registered ECC modules and a BIOS revision that recognises 128 GB per DIMM at 4800 MT/s.

Will the CL40 4Rx4 sticks work alongside older DDR5 4800 modules already in the XE9680?

Yes, if the existing modules are also DDR5 4800 ECC RDIMMs; the system will run all channels at the common 4800 speed and CL40 latency.
