Im looking to upgrade the ram of the computer (I currently have 16 gb) and was wondering how to determine if memory sticks will be compatible before I purchase them.

Crucial’s on line guide is good for replacement: https://www.crucial.com/compatible-upgra…) and RAMMon (free for personal use) is an old standby to find out what RAM you have: https://www.passmark.com/products/rammon… and finally The Dell Inspiron-14 5482 Service Manual: https://topics-cdn.dell.com/pdf/inspiron

Yes. Ram is not interchangeable. Find the technical specs for your model of laptop from Dell’s website and find the DDR and the clock speed. For finding the ram you need: You will need to find SO-DIMM (laptop form factor) ram with the same DDR (will be either 3 or 4) and the same clock speed
