Dell 8GB DDR4 2666 MHz RDIMM Memory Module

The Dell A9781927 is an 8 GB DDR4 registered DIMM that runs at 2666 MHz and is intended for servers requiring steady, high-bandwidth memory. Its registered architecture reduces the electrical load on the memory controller, which supports stable operation when many modules share the same bus.

The module uses a single rank layout, a design that can lower latency and improve power efficiency compared with multi-rank alternatives. This makes it a practical upgrade for virtualization hosts, database servers, or any business critical environment where consistent throughput and reliability are essential.

Because the A9781927 ships in a kit format, administrators can drop it into an open slot or use it to replace a failing module without adjusting BIOS settings or running firmware updates. Snap it into a server that accepts DDR4 2666 MHz RDIMMs and the system will recognize the additional capacity on the next boot, allowing workloads and virtual machines to tap into the expanded memory pool right away.

Whether you are expanding capacity to meet growing demand or restoring a server after a memory fault, this module provides a straightforward path to maintaining performance and uptime.
