Genuine Crucial by Micron 4GB DDR4 laptop memory module. This is a DDR4 SODIMM designed for laptops and small form factor systems that support DDR4 memory. Crucial is a top-tier manufacturer known for reliability and broad compatibility. Ideal for replacing a failed module or upgrading supported systems that use DDR4-2400 memory. It is one 4gb stick but is in a package that says 8gb. I only used the one stick out of this package. Not this one.
