Dell PowerEdge XE9680 DDR5 RDIMM

This 128GB DDR5 4800 ECC registered DIMM is built for Dell PowerEdge XE9680 servers that require registered memory with error correction. The single 4Rx4 module operates at 1.10V and carries a CL40 latency rating.

Check DDR5 RDIMM slot population rules

Verify the server supports 4Rx4 registered DDR5 modules and confirm the maximum capacity per channel before ordering. The 288-pin form factor fits DDR5 RDIMM slots only; it will not fit UDIMM or previous-generation sockets.

Replaces lower-capacity DDR5 RDIMMs

Upgrading from smaller registered DDR5 modules adds 128GB in a single slot, useful when all slots are occupied or when workloads need maximum density per channel. The jump is worth it when ECC registered memory at 4800 MT/s matches the platform specification.
