Crucial 8GB DDR4 2666 MHz SODIMM Laptop Memory Module

The Crucial CT8G4SFRA266 is a SODIMM that offers 8GB of DDR4 memory for notebook computers and compact desktops that accept a 260 pin slot. With a speed of 2666 MHz, the module moves data more quickly than many factory configurations, so everyday activities such as web browsing, spreadsheet work and streaming feel more fluid. The 1.2 volt operating design keeps power draw modest, which encourages cooler operation and longer battery life on the go.

Installation is quick because the module follows the JEDEC PC4-21300 standard and a 19-19-19 timing profile. Simply press it into the open slot, power on, and most systems recognize the additional capacity automatically. A CAS latency of 19 balances speed with reliable operation, and the non-ECC, unbuffered build matches what the vast majority of consumer and office laptops expect.

Crucial relies on Micron engineering for every component, so compatibility testing covers a wide range of brands and models. The result is an upgrade that just works, whether you need a single module to reach 8GB or plan to pair two modules for dual channel performance. Students, remote workers and casual creators will appreciate the smoother multitasking that comes from added memory, and extending the life of a trusted laptop is often far more economical than buying a new machine.
