Dell PowerEdge FC640 Server Memory

This 64GB DDR4 2933MHz ECC registered DIMM is built for the Dell PowerEdge FC640 server. It delivers 64GB capacity in a single 288-pin module running at 1.2V with CL21 latency. The 2Rx4 organisation and major-brand DRAM chips provide the error correction and signal integrity required in production server environments.

Suited for FC640 capacity upgrades

IT teams expanding memory in a Dell PowerEdge FC640 will find this module matches the platform's registered ECC requirement. Buyers needing unbuffered memory, non-ECC modules, or a different DDR generation should look elsewhere because this part is specific to registered DDR4 server boards.

Registered ECC DDR4 2933MHz 2Rx4

The registered ECC DDR4 2933MHz 2Rx4 specification determines compatibility with the Dell PowerEdge FC640 memory controller. The module operates at 1.2V with CL21 timing and uses a 288-pin RDIMM form factor. Verify that your server configuration supports 64GB single-rank population rules before ordering.

Questions about this item

What does 64GB DDR4 2933MHz CL21 mean for a Dell PowerEdge FC640?

The module adds 64GB of registered ECC memory running at 2933MHz with CL21 latency, expanding the server's total capacity and maintaining error correction for critical workloads

How does the DDR4 2933 (PC4-23400) interface affect real-world speed?

The DDR4 2933 interface sets the maximum data rate at 2933MT/s; the server's memory controller and CPU configuration determine the actual operating frequency

What physical slot and clearance does this 288-pin RDIMM need?

It fits a standard 288-pin DDR4 RDIMM slot and has no heat spreader, so it clears most CPU coolers and adjacent modules in the PowerEdge FC640 chassis
