Crucial 64GB DDR4 2666 MHz SO-DIMM Memory Kit for Mac (2 x 32GB)

The Crucial CT2K32G4S266M is a 64GB DDR4 2666 MHz SO-DIMM memory kit that lets your Mac handle bigger projects and heavier multitasking without slowing down. It ships as two 32GB modules, giving iMac and Mac mini owners an immediate boost in available memory so large files open faster and more apps stay responsive.

If you spend your day editing 4K video in Final Cut Pro, layering tracks in Logic Pro, running virtual machines for development, or keeping countless browser tabs open while retouching photos, this upgrade helps keep everything moving smoothly. The 2666 MHz clock speed reduces the need for your system to swap data to the internal drive, which translates into shorter render times and quicker application launches.

Installation is straightforward. Open the memory access panel on your compatible Mac, release the existing modules, and press these in until they click. The 260-pin design is unbuffered and non-ECC, the modules run at a low 1.2 V, and the CAS latency is 19—all specifications that match what modern Mac systems expect. Each stick is tested at the factory to meet Apple requirements, so you can install with confidence.

Engineered by Crucial and backed by Micron, the kit carries a limited lifetime warranty, offering peace of mind while extending the useful life of your computer. Instead of replacing your Mac, you can unlock more performance with a simple memory swap.
