Server-grade DDR4 ECC RDIMM

This 32 GB DDR4 2666 MHz module is a registered ECC DIMM built for server and workstation platforms. It operates at the standard 1.2 V DDR4 voltage and uses a 2Rx4 organisation with CL19 latency. The 288-pin form factor fits DDR4 DIMM slots in compatible enterprise systems.

Dell-compatible replacement upgrade

The module replaces Dell part numbers including A9781929, A9810563, A9810568, AB003150, AB128249, CG17D, SNPTN78Y/32G, SNPTN78YC/32G and SNPTN78YC/32VXR. It is intended for administrators expanding memory capacity in qualified Dell servers or workstations that require registered ECC DDR4 2666 memory. The jump is worth it when the platform supports this speed and rank configuration.

Suited for qualified Dell enterprise systems

Buyers should verify their system's qualified vendor list before purchase to confirm 32 GB 2Rx4 RDIMM support at 2666 MHz. It is not suitable for desktop consumer boards that accept only unbuffered non-ECC memory, nor for platforms limited to lower densities or different rank organisations.

Questions about this item

Does the 288-pin DDR4 DIMM fit a standard server RDIMM slot?

Yes, it uses the 288-pin DDR4 DIMM form factor required for registered ECC slots in compatible servers and workstations.

What BIOS setting or step is often missed when installing this registered ECC module?

After seating the 2Rx4 RDIMM, enable ECC in the system BIOS so the server can use the error-correcting capability of the module.

When should the 32GB DDR4 2666MHz ECC RDIMM be replaced?

Replace the module if memory diagnostics report uncorrectable ECC errors or if the system fails POST with the module installed.
