Dell 32GB DDR4 2666 MHz Memory Module

The Dell A9781929 is a 32 GB memory upgrade that uses DDR4 technology running at 2666 MHz to give compatible Dell servers and workstations extra headroom for demanding workloads. With more memory available, virtualization hosts can support additional guests, databases can cache larger data sets, and creative applications can work with big projects without constant disk swapping.

The module includes error correcting code and a registered design, two features that help maintain stability when uptime is critical. ECC detects and corrects single-bit errors on the fly, while the registered layout ensures cleaner signaling across the memory bus in multi-DIMM configurations.

Its 288-pin interface conforms to the standard used in modern server motherboards, and the 1.2 V operating voltage keeps power consumption and heat generation in check. Lower power draw matters in dense racks, where every watt saved can translate into reduced cooling costs and greater overall efficiency.

Dell has qualified this module for systems such as the PowerEdge R740 and R940 servers as well as the Precision 7820 workstation. Installation is straightforward: power down the system, open the chassis, align the module with the slot, press until the latches click into place, then reboot and verify the new capacity through the BIOS or operating system.

Whether you manage virtual machines, run analytics, or render complex scenes, adding this memory allows the system to hold more data in RAM and stay responsive during peak loads.
