Dell PowerEdge XE9640 memory kit

This 256 GB kit contains eight 32 GB DDR5 4800 RDIMM modules built for the Dell PowerEdge XE9640 rack server. Each module is ECC registered with a CL40 latency and runs at 1.1 V. The kit is designed for IT teams upgrading that specific platform.

Capacity and headroom

Eight 32 GB sticks deliver 256 GB of registered ECC memory at DDR5 4800 speed. The 2Rx8 organisation and CL40 timing suit heavy virtualisation and database workloads. The kit fills eight DIMM slots and reaches the platform limit for this configuration.

Build integration

Modules use the standard 288-pin DDR5 RDIMM form factor and operate at 1.1 V. No heat spreaders are fitted so airflow in the Dell chassis is unrestricted. Installation follows the server's documented memory population rules for registered DIMMs.

Preguntas sobre este artículo

Will the eight 32 GB DDR5 4800 CL40 ECC RDIMMs work alongside other DDR5 modules already installed in the PowerEdge XE9640?

The kit provides 256 GB in eight 2Rx8 registered DIMMs at 1.1 V; mixing ranks or speeds can prevent the server from posting, so populate all slots with identical modules for guaranteed operation.

How can I verify the 256 GB kit is running at the rated 4800 MT/s and CL40 after installation?

Enter the system BIOS or iDRAC interface and confirm the memory speed reads 4800 MT/s with CAS latency 40; the modules are stress-tested before shipping to meet those timings.

What exactly ships in the box and what must be sourced separately for the PowerEdge XE9640 upgrade?

The package contains the eight 32 GB DDR5 4800 ECC RDIMMs only; no heat spreaders, tools or additional cables are included or required for installation.
