Dell PowerEdge XE9680 memory kit

This 1 TB kit contains eight 128 GB DDR5 RDIMM modules built for the Dell PowerEdge XE9680 rack server. It targets administrators who need maximum registered ECC capacity in a single qualified package.

Registered ECC modules for dense server

Each stick is a 288-pin DDR5 4800 RDIMM with 4Rx4 organisation and on-die ECC, so the memory controller handles error correction without extra buffer chips. The registered interface reduces electrical load on the server memory bus, allowing all eight slots to be populated at the rated 1.10 V.

1 TB total capacity with CL40 latency

The kit delivers 1 TB of addressable memory for large virtualisation clusters, in-memory databases or HPC workloads that scale across many cores. At CL40 the modules run at the standard JEDEC DDR5 4800 rate; workloads requiring higher bandwidth or lower latency would need faster-rated DIMMs.

Questions about this item

What is the CAS latency of this 128 GB DDR5 4800 module under sustained load?

The modules run at CL40 latency at the rated 4800 MT/s speed.

How much power does each 1.10 V registered DIMM draw in a Dell PowerEdge XE9680 running continuously?

Each DIMM operates at 1.10 V; registered DDR5 RDIMMs at this voltage typically draw only a few watts per module under load.

What server platform must already be installed for this 8-module kit to function?

The kit is validated for the Dell PowerEdge XE9680 rack server.
