Dell PowerEdge XE9680 memory kit

This 512GB kit contains eight 64GB DDR5 4800 modules built for the Dell PowerEdge XE9680 rack server. It delivers registered ECC memory in a single validated package for enterprise workloads. The modules operate at 1.10V with CL40 latency and a 2Rx4 rank structure.

Registered ECC RDIMM specification

The decisive specification is the registered ECC RDIMM design with 288-pin DDR5 form factor. This ensures signal integrity and error correction required by the PowerEdge XE9680 platform. Unbuffered or non-ECC modules will not function in this server.

512GB capacity for dense compute

Eight 64GB modules populate eight slots to reach 512GB total capacity. This supports large-scale virtualization, in-memory databases and AI training datasets. Expansion beyond this kit requires additional compatible slots and matching module specifications.

Questions about this item

What does the 4800 MT/s DDR5 rating mean once the modules are installed in a PowerEdge XE9680?

The kit runs at 4800 MT/s, delivering PC5-38400 bandwidth per module when the server's memory controller is set to the standard DDR5 4800 profile.

How does the 288-pin RDIMM interface and registered design affect usable capacity and speed in this server?

The 288-pin DDR5 RDIMM form factor with registered buffering allows all eight 64 GB modules to operate at the rated 4800 MT/s without signal integrity limits that unbuffered DIMMs would hit at this density.

What physical slot requirements must the XE9680 meet to accept this 8-module kit?

The server needs eight free 288-pin DDR5 RDIMM slots; each module is a standard-height 2Rx4 registered DIMM with no heat spreader, so no extra clearance beyond the stock slot spacing is required.
