## Description

More speed. More battery life. More memory capacity. Fuel your next-gen laptop In the ever-changing world of technology, any component more than five years old is usually in need of an update. At seven years old and counting, that's where DDR3 memory is at: laptops can only do so much with it. Since the introduction of DDR3 memory technology in 2007, processors have doubled in capability, SSDs have revolutionized throughput and graphics cards have drastically increased frame rates, leaving memory as a limiting factor. With Crucial DDR4 SODIMMs, crush the DDR3 memory bottleneck and unlock a new standard of performance. More Energy Efficient Extend battery life by using less power. Operating at just 1.2V compared to 1.5V for standard DDR3 memory, Crucial DDR4 SODIMMs consume 20% less voltage than standard DDR3 technology. Crucial DDR4 SODIMMs also contain other efficiency features, for an overall power reduction of up to 40%. More Density Pack more memory into your laptop than ever before. Crucial DDR4 SODIMMs debut in densities up to 8GB and as DDR4 technology develops, modules are projected to hit 32GB - allowing you to install twice as much memory as you could in a DDR3 system. Since laptops only have 1-2 memory slots, high-density Crucial DDR4 SODIMMs allow you to overcome this limitation and install more memory for faster mobile performance. More Speed Load applications faster and run demanding programs

Review: Easy upgrade that works perfectly - This memory kit installed easily and worked right away. It improved performance and has been running reliably with no issues.
Review: Great easy upgrade for a basic laptop. - I only need one dimm but for a few extra bucks I got the set to be safe that they would work together. I thought about getting 16gb but since it was a free upgrade for the neighbor I decided going from 4 to 8 would be good enough.
