Dell-Compatible 16GB DDR4-2666 ECC RDIMM

This 16GB DDR4-2666 registered DIMM is built for servers and workstations that require error-correcting memory. It carries the Dell AA546831 part number equivalent and uses major-brand DRAM chips. The module is designed for 288-pin DDR4 slots running at 1.2V. It targets IT professionals maintaining Dell platforms or building compatible systems.

16GB Capacity with PC4-21300 Speed

The module delivers 16GB of capacity at a 2666 MT/s data rate, rated as PC4-21300. Registered buffering and ECC protect data integrity under sustained loads typical of virtualization and database workloads. The dual-rank 2Rx8 organization balances density and signal loading. Headroom is limited to the rated 2666 speed; overclocking or higher JEDEC profiles are not supported by this specification.

288-Pin Registered Form Factor for Compatible

Installation requires a motherboard with 288-pin DDR4 RDIMM slots that support registered, ECC memory at 1.2V. The registered design reduces electrical load on the memory controller, freeing electrical headroom for higher total system capacity when multiple modules are populated. Systems limited to unbuffered UDIMMs or non-ECC memory cannot use this module.

Questions about this item

Will this 2666 MHz ECC registered RDIMM run alongside my existing DDR4 ECC registered modules at the same voltage?

The module operates at 1.20 V and 2666 MHz. The server memory controller will set all populated slots to the lowest common speed and voltage, so mixing with slower DDR4 ECC registered DIMMs is typical.

How can I verify the 16 GB 2Rx8 module is recognised and running with ECC active after installation?

Enter the server BIOS or UEFI and confirm the total capacity shows the expected 16 GB per DIMM, the speed reads 2666 MT/s, and ECC status is reported as enabled or active.

Does the single 288-pin RDIMM ship alone, or do I need to buy a matching pair for dual-channel operation?

The box contains one 16 GB 288-pin DDR4 RDIMM. Dual-channel performance depends on your platform; order a second identical module if your configuration requires a matched pair.
