Dell FC640 16GB DDR4 RDIMM

This 16GB DDR4 2933MHz ECC registered DIMM is built for the Dell PowerEdge FC640 server. It delivers 16GB of capacity at 1.2V with CL21 latency and a 2Rx8 organisation. The 288-pin module uses major OEM chips from Samsung, Micron or Hynix.

Upgrading from lower capacity or slower DDR4

Replacing smaller RDIMMs or slower DDR4 modules with this 16GB PC4-23400 part increases total memory bandwidth and allows larger working sets in virtualisation or database workloads. The jump is worth it when the FC640 chassis has free DIMM slots and the workload is memory bound.

Suited for FC640 owners needing registered ECC

IT teams running Dell PowerEdge FC640 servers who need validated registered ECC memory for stability will find this module a direct fit. Buyers who need unbuffered memory, non-ECC modules, a different form factor or support for a different server platform should look elsewhere.

Questions about this item

Does the 288-pin DDR4 RDIMM fit the Dell PowerEdge FC640 memory slots?

Yes, the module uses the standard 288-pin DDR4 RDIMM form factor required by the FC640 server.

Do I need to install matched pairs or can I add this single 16 GB stick?

The FC640 supports single-module installation; insert the RDIMM into an empty slot and the system will register the 16 GB automatically.

Will the ECC registered chips require any firmware updates or special cooling later?

No firmware update is needed; the module runs at 1.2 V without a heat spreader and relies on the server's standard airflow.
