A:Answer I don’t know about your Dell. I bought becuz a geek squad guy told me this is what I needed to fix my 15” HP. So I bought it, and although it fixed my problem, they could only install 1 of the 2 memory sticks. Becuz there wasn’t room for both units. So, before spending twice as much as you need ( like me), make sure you physically have room inside your machine for both.
