Capacity and compatibility

This 256GB kit contains four 64GB DDR5 registered DIMMs built for the Dell PowerEdge XE9680. The modules carry ECC and registered buffering for data integrity in server workloads. Buyers who need non-ECC consumer memory or a different form factor cannot use this kit.

Sustained-load behaviour

ECC correction and registered signalling keep data accurate during continuous enterprise tasks such as database serving or virtualisation hosting. The 4800MHz rating and CL40 latency are maintained at the specified 1.1V across the full 256GB population. Systems that require higher frequencies or lower latencies will not reach those targets with this module.

Installation notes

The 288-pin DDR5 RDIMMs install in the standard server DIMM slots following the XE9680 population rules. Mixing ranks or capacities across channels can prevent the system from posting, so all four identical 2Rx4 modules should be deployed together. Servers that limit total memory per socket below 256GB will not accept the full kit.

Questions about this item

How much power does each 64 GB DDR5 4800 module draw at 1.1 V during continuous operation?

Each module runs at 1.1 V; total kit capacity is 256 GB across four 64 GB sticks.

What must the Dell PowerEdge XE9680 already have to accept this 288-pin DDR5 RDIMM kit?

The server needs free DDR5 RDIMM slots that support 2Rx4 registered ECC modules at 4800 MT/s.

Will this CL40 2Rx4 kit run correctly beside existing DDR5 4800 RDIMMs already installed in the XE9680?

Yes, matched speed, voltage, rank and ECC registration allow mixed population in the same server.
