4GB DDR4 2400 ECC RDIMM

This 4GB DDR4 2400 ECC registered DIMM is built for servers and workstations that require error-correcting memory. It fits 288-pin slots and runs at the standard 1.2V voltage. The module uses major-brand chips and carries a CL17 latency rating. It replaces Dell part numbers A8711885, A9654880, SNPFPFP6C/4G and SNPK67DJC/4G.

Sustained-load behaviour

Registered buffering and ECC circuitry keep data integrity intact during continuous, multi-threaded workloads. The 1Rx8 organisation allows the memory controller to address the rank efficiently across long sessions. Operation at 1.2V limits thermal output when the system runs at full capacity for extended periods. Quality-assurance testing validates stability under prolonged stress.

Upgrade context

This module upgrades systems currently running lower-capacity or non-ECC DDR4 DIMMs in compatible Dell platforms. The jump is worthwhile when applications demand registered ECC memory for data integrity or when additional 4GB increments are needed to reach the platform's supported population limits. Buyers who need higher-density modules or non-registered memory should verify their platform requirements first.

Questions about this item

How much power does this 1.20V DDR4 2400 module draw under continuous server load?

The module operates at the standard DDR4 voltage of 1.20V, which keeps power draw low during all-day operation in registered server DIMM slots.

Does my Dell server need a registered DIMM slot to accept this 288-pin ECC RDIMM?

Yes, this is a 288-pin DDR4 ECC Registered DIMM, so the system must support registered memory and have an available DDR4 RDIMM slot.

Will this CL17 1Rx8 stick run at 2400 MHz if I install it alongside slower DDR4 modules already in the system?

The module is rated for DDR4 2400 (PC4-19200) at CL17; the memory controller will set the common speed based on the slowest installed DIMM.
