Crucial 32GB DDR4 2666 MHz DIMM Memory Module Kit (2 x 16GB)

The Crucial CT2K16G4DFD8266 is a 32 GB desktop memory kit that pairs two 16 GB DDR4 modules to give your system more headroom for demanding work. Running at 2666 MHz, it can move data quickly enough to keep large spreadsheets, virtual machines, and modern games from slowing you down.

Each module uses a 288-pin DIMM layout, so installation is as simple as seating the sticks in any motherboard that supports DDR4 at 2666 MHz. A dual-rank design helps improve throughput, while the 1.2 V operating voltage keeps power draw and heat in check. With a CAS latency of 19, the kit balances speed with rock-solid stability, making it a sensible upgrade for offices that rely on OptiPlex towers as well as for home builders who want smooth multitasking without diving into overclocking.

If you edit 4K video, compile large codebases, or keep dozens of browser tabs open while streaming, the additional 32 GB of capacity helps prevent slowdowns caused by disk swapping. Gamers will notice quicker level loads and fewer stutters when background applications are running. Creative professionals can run photo and design tools side by side, and IT staff can assign more memory to virtual machines without starving the host system.

Like every Crucial module, the kit is built on Micron-manufactured components and tested for compatibility with non-ECC desktop platforms. Most systems will recognize the memory automatically, so you can power up and get back to work within minutes.
