A9781928-AM Dell 16GB PC4-21300 DDR4-2666MHz Memory Module

A9781928-AM Overview

The A9781928-AM is a 16GB DDR4-2666MHz ECC Registered memory module designed and validated for Dell PowerEdge servers. Running at 2666MHz with CL19 timings, dual-rank architecture, and registered buffering, this 288-pin DIMM operates efficiently at 1.2V and delivers the stable, error-corrected performance that Dell server environments require for 24/7 operation.
With built-in ECC technology, the module detects and corrects memory errors in real time, significantly reducing the risk of data corruption and unexpected crashes during demanding workloads. The dual-rank design combined with registered buffering improves memory efficiency and signal integrity, allowing servers to support higher capacities and multiple modules without stability issues.
