I own a Dell Inspiron R14 (5420) laptop (i5 3rd gen). Currently, it has 4GB of RAM installed, but I would like to increase the RAM to 8GB. I don't know how to figure out what the specifications should be for the replacement RAM. How can I find out what type of RAM to purchase for my laptop?

Googling Inspiron 5420 ram will give you an answer pretty quickly. Spec for the RAM is DDR3 PC3-12800, DDR3 PC3-10600, DDR3 (non-ECC) SODIMM - and you will need 2 x 4 GIG sticks. It might be an idea to have a look at what RAM is currently installed, so you know if you have 1 or 2 sticks and the speed - you may be able to save yourself the cost of 1 stick. [ You should always try get identical memory though ]

One of the nice things about Dell is their service tags. You can typically find this reference on the bottom of the notebook - plug it into their website and it will show you the details of the computer, normally including the RAM configuration.
