Dell PowerEdge XE9640 Memory Kit

This kit provides 1TB of DDR5 memory across sixteen 64GB registered DIMMs for the Dell PowerEdge XE9640 rack server. It is built for IT teams running memory-intensive workloads such as virtualization, databases or high-performance computing clusters. The modules are tested for stability in mission-critical enterprise environments.

Compatibility and Slot Requirements

Verify that the server has sixteen free 288-pin DDR5 RDIMM slots and that the BIOS supports PC5-38400 registered ECC modules at 1.1V. The kit uses a 2Rx4 organisation with CL40 latency, so the memory controller must accept this rank configuration. Check the Dell service manual for approved population rules before ordering.

Thermals and Power Profile

Operating at 1.1V, the modules draw minimal power per DIMM and run without heat spreaders in the server's managed airflow. Registered buffering reduces electrical load on the memory controller during sustained throughput. Expect quiet, stable operation under typical enterprise workloads when the chassis fans follow Dell's thermal profile.

Highlights

  • 1TB total capacity with sixteen 64GB modules
  • DDR5 4800 speed rated at PC5-38400
  • ECC registered RDIMM for data integrity
  • 2Rx4 dual-rank organisation per module
  • 10V low-voltage operation at CL40 latency

Questions about this item

What is included in the box and do I need to purchase any additional components?

The kit contains sixteen 64 GB DDR5 4800 CL40 2Rx4 1.1 V 288‑pin ECC RDIMM modules for a total of 1 TB. No extra memory parts are required; install the modules directly into the Dell PowerEdge XE9640 memory slots.

How do I decide between the available versions or capacities for this kit?

This listing is a single 1 TB kit built from sixteen 64 GB modules. If your workload needs a different total capacity, you would select another kit with the appropriate number of 64 GB modules rather than mixing capacities.

What does the 4800 MT/s rating mean once the memory is installed in the PowerEdge XE9640?

The modules run at DDR5 4800 (PC5‑38400) with CL40 latency at 1.1 V, delivering the rated bandwidth and error‑correcting registered operation that the XE9640 platform expects for stable server workloads.
