Dell-compatible 16 GB DDR4-2666 ECC RDIMM

This 288-pin registered module delivers 16 GB of DDR4 memory at 2666 MT/s with ECC error correction. It operates at 1.2 V and uses a 2Rx8 rank organisation. The part is built with major-brand DRAM and matches Dell part number AA174381 for drop-in server upgrades.

Registered ECC with 2Rx8 organisation

The registered buffer and ECC circuitry are the decisive specification for compatibility; only platforms that accept registered ECC DDR4 RDIMMs can use this module. The 2Rx8 layout determines how the memory controller addresses the chips, so the server's qualified-vendor list must explicitly support this rank configuration.

Fills a single DDR4 RDIMM slot

Installation requires an available 288-pin DDR4 RDIMM slot on a motherboard qualified for registered ECC memory at 2666 MT/s. The module draws 1.2 V, leaving headroom within the standard DDR4 voltage envelope, and its matched major-brand chips allow populations of identical modules for multi-channel configurations.

Questions about this item

Will the 2666 MT/s speed run at that rate in my server or drop to a lower JEDEC bin?

The module is rated DDR4-2666 (PC4-21300) and will operate at 2666 MT/s provided the platform supports that speed; otherwise it will down-clock to the highest common speed the CPU and chipset allow.

Does the 288-pin registered ECC design require a specific motherboard slot type?

Yes, it needs a DDR4 RDIMM slot that supports registered ECC memory; standard desktop UDIMM slots will not accept this module.

What clearance does the 2Rx8 registered DIMM need around the CPU socket?

The 288-pin RDIMM follows the standard DDR4 form factor, so it fits any server board with adequate DIMM-slot spacing — no extra height or heatsink clearance beyond the normal specification is required.
