Dell PowerEdge FC640 compatible memory

This 16 GB DDR4 2933 module is built for the Dell PowerEdge FC640 server. It delivers ECC registered operation for data integrity in enterprise workloads. The single DIMM format suits capacity upgrades or replacement in qualified systems. IT teams maintaining this platform can install it without proprietary Dell part sourcing.

Registered ECC RDIMM build

Registered buffering reduces electrical load on the server memory controller for stable operation at 2933 MT/s. The 288-pin DDR4 RDIMM keying prevents insertion into unbuffered or consumer slots. ECC circuitry corrects single-bit errors to protect critical data. No heat spreader is fitted, matching the original Dell thermal design for this chassis.

2933 MT/s CL21 2Rx8 specification

The module runs at DDR4 2933 (PC4-23400) with CAS latency 21 at 1.2 V. Dual-rank 2Rx8 organisation provides density for the FC640 memory architecture. Systems requiring a different speed grade, rank configuration or voltage will not operate correctly with this part.

Questions about this item

What does the DDR4 2933 (PC4-23400) rating mean for maximum data rate?

The module runs at 2933 MT/s, giving a peak bandwidth of PC4-23400; the server memory controller will not exceed this speed.

Will this 288-pin RDIMM fit the Dell PowerEdge FC640 memory slots?

Yes, the 288-pin DDR4 RDIMM form factor matches the FC640 DIMM slots; the registered design and 2Rx8 organisation are supported by that platform.

How do I install the module, and what step is often missed?

Power off the server, open the chassis, align the notch on the 288-pin edge connector with the slot key, press firmly until both retention clips click, then verify in BIOS that the 16 GB appears at 2933 MT/s with ECC active.
