System-specific memory kit for Dell PowerEdge XE9640

This 512 GB kit contains eight 64 GB DDR5 RDIMMs rated at 4800 MT/s with CL40 latency. Each module is registered, ECC-enabled and organised as 2Rx4 for server workloads. The kit targets IT teams upgrading compatible Dell rack servers.

Compatibility check for Dell PowerEdge XE9640

Verify that your XE9640 supports 512 GB of registered ECC DDR5 at 1.1 V and that all eight DIMM slots are available. Confirm the system BIOS recognises 2Rx4 modules and that the memory configuration follows Dell population rules.

Build quality and daily implications

Modules use major OEM DRAM from Samsung, Micron or Hynix and are stress-tested under load before shipment. The 288-pin RDIMM form factor fits standard DDR5 server slots without a heat spreader, leaving clearance for dense rack airflow. Registered buffering and ECC protect data integrity in continuous operation.

Questions sur cet article

Does the kit ship with eight 64 GB modules, or do I need to buy any sticks separately?

The kit contains eight 64 GB DDR5 RDIMMs, giving a total of 512 GB; no additional modules are required.

Should I pick the 2Rx4 CL40 version or a different rank and latency for the PowerEdge XE9640?

This 2Rx4 CL40 kit matches the Dell-qualified specification for the XE9640, so it is the correct choice for that server.

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

The modules run at 4800 MT/s (PC5-38400) with CL40 latency at 1.1 V, delivering the rated bandwidth and error-correction the platform expects.
