Dell PowerEdge XE9680 DDR5 kit

This 512GB kit supplies four 128GB registered DDR5 modules built for the Dell PowerEdge XE9680. ECC protection and registered signalling keep data integrity intact under continuous enterprise workloads.

512GB capacity with 4Rx4 organisation

Four ranks per module deliver high density for virtualisation, large databases and in-memory analytics. CL40 latency at 4800 MT/s provides steady throughput until the platform's memory controller or CPU core count becomes the limiting factor.

Upgrade from smaller RDIMM sets

Replacing lower-capacity registered kits removes DIMM-slot pressure and avoids mixed-rank configurations. The jump is worthwhile when workloads exceed current memory headroom and the server's qualified-vendor list approves this part number.

Questions about this item

Will these 4Rx4 DDR5 4800 modules run with my existing 2Rx4 RDIMMs in the PowerEdge XE9680?

Dell qualified this kit for the XE9680; mixing ranks is not validated by the vendor, so matching all slots with identical 4Rx4 modules is the supported configuration.

How can I confirm the 512GB kit is running at 4800 MT/s and CL40 after installation?

Enter BIOS or iDRAC and verify the memory speed reads 4800 MT/s with CAS latency 40; the registered ECC modules also report health status in the system management console.

Does the MR38400-744K4 package include only the four 128GB RDIMMs or any extra cables or brackets?

The box contains exactly the four 288-pin DDR5 128GB ECC RDIMMs; no cables, brackets or additional accessories are included.
