Dell PowerEdge Server Memory Upgrade

This 16 GB DDR4 module is built for Dell PowerEdge R6515, R6525, R750, R750xa and R750xs servers. It delivers ECC registered operation at 3200 MHz with CL22 latency and 1.2 V power draw. The part replaces several Dell original numbers including AA783421, AA799064 and AB214251. It is not suitable for standard desktop computers.

DDR4 Registered DIMM Constraints

Registered ECC RDIMMs cannot be mixed with unbuffered memory in the same system. The 288-pin form factor fits only DDR4 server platforms that support registered modules. Buyers who need non-ECC or unbuffered memory for a workstation or consumer board cannot use this module.

16 GB Dual-Rank Capacity Decides Fit

Each stick provides 16 GB in a 2Rx8 organisation running at PC4-25600 speed. Matching capacity, speed and rank across all populated slots is required for optimal performance. Systems needing a different density or rank configuration will not be served by this part.

Questions about this item

Should I pick the 16GB module or a different capacity for my Dell PowerEdge R750?

This module provides 16GB per DIMM; match the total capacity you need by filling the available slots with identical 16GB sticks.

What does the 3200MHz rating deliver inside a Dell PowerEdge R6515?

The DDR4 3200 speed (PC4-25600) runs at 3200MT/s with CL22 latency, giving the rated bandwidth when the server’s memory controller operates at that frequency.

Will the 288-pin RDIMM work with the registered ECC slots in a Dell PowerEdge R750xa?

Yes — it is a 288-pin DDR4 ECC Registered RDIMM (2Rx8, 1.2V) designed for those server platforms and replaces Dell part numbers such as AA783421 and SNPM04W6C/16G.
