Dell PowerEdge XE9680L 128GB DDR5 RDIMM

This 128GB DDR5 ECC RDIMM is built for the Dell PowerEdge XE9680L rack server. Registered buffering and error-correcting code protect data integrity in demanding enterprise workloads. The module delivers 6400MHz speed at CL52 latency for high-throughput tasks. It targets IT teams expanding memory capacity in compatible Dell platforms.

Verify server memory configuration before ordering

Confirm the PowerEdge XE9680L supports 4Rx4 registered DIMMs at 1.1V operation. Check available DIMM slots and maximum capacity per channel in the system documentation. Ensure the BIOS revision recognises 128GB density modules. Mixing ranks or voltages can prevent boot or reduce performance.

288-pin RDIMM with major OEM DRAM chips

Samsung Micron or Hynix components populate the module without a heat spreader. The registered design adds a buffer between the memory controller and DRAM for signal stability. Standard 288-pin DDR5 keying prevents misinstallation in incompatible slots. Single-module packaging simplifies incremental upgrades.

Questions about this item

Does the package include only the 128GB DDR5 6400MHz CL52 288-Pin ECC RDIMM module, or are any extra parts needed?

The package contains one 128GB DDR5 6400MHz PC5-51200 4Rx4 1.1V CL52 288-Pin ECC RDIMM. No additional components are required for installation in a compatible Dell PowerEdge XE9680L server.

How do I decide between the listed 128GB 4Rx4 6400MHz CL52 version and any other capacity or rank options?

This module is a single 128GB 4Rx4 DDR5 6400MHz CL52 ECC RDIMM. Choose it when your Dell PowerEdge XE9680L configuration calls for a 128GB registered DIMM at this speed and rank; other capacities or ranks would be different part numbers.

What does the 6400MHz PC5-51200 rating mean for actual performance once the DIMM is installed in the server?

The module runs at 6400MHz with CL52 latency at 1.1V, delivering PC5-51200 bandwidth. In the Dell PowerEdge XE9680L it operates at the platform's supported DDR5 6400MHz registered ECC speed, providing the rated throughput and error correction for server workloads.
