Crucial PC3-12800 4GB Memory Module DDR3L 1600MHz CT51264BF160BJ

Crucial PC3-12800 4GB. Component for: Notebook, Internal memory: 4 GB, Memory layout (modules x size): 1 x 4 GB, Internal memory type: DDR3L, Memory clock speed: 1600 MHz, Memory form factor: 204-pin SO-DIMM, CAS latency: 11

In short, 204-pin small outline dual inline memory modules (SODIMMs) are the form factor used to provide DDR3 memory modules for notebook computers and other small form factor computing platforms. 204-pin SODIMMs are currently available in PC3-8500 (DDR3 1066MHz) and PC3-10600 (DDR3 1333MHz) speeds.

To use DDR3 memory, your system must have both a 204-pin SODIMM slot and a chipset that supports DDR3 memory. A DDR3 SODIMM will not fit into DDR2 or DDR memory sockets.
