Compatible Dell and Fujitsu desktop upgrade

This 16 GB DDR4 module is built for the Dell Inspiron 3671 desktop and Fujitsu ESPRIMO D588/T systems. It delivers a single-stick capacity increase for owners of those machines who need more memory. The part is validated for the listed models so installation proceeds without guesswork.

Unbuffered DIMM with standard 288-pin layout

The stick uses a plain 288-pin unbuffered DIMM form factor without a heat spreader. It fits the two available memory sockets in each compatible chassis and sits at the standard 1.20 V operating voltage. No extra power cables or BIOS steps are required beyond seating the module firmly.

2666 MHz CL19 speed grade

Rated at 2666 MHz (PC4 21300) with 19-19-19 timings, this module runs at the fastest JEDEC speed the supported platforms accept. All installed memory will operate at the slowest module or processor limit, so matching this specification keeps the system at its peak supported frequency.
