Dell Inspiron 5459 Ram upgrade

Hi all,

I am looking to upgrade my ram from 4GB to 8GB. I downloaded an app called CPU-Z to check the RAM specs. My laptop is a Dell Inspiron 5459 (Not vostro)

Laptop Specs

CPU : Intel Core i7-6500U

GPU : Intel(R) HD Graphics 520

GPU (dedicated) : AMD Radeon(TM) R5 M335 4GB

RAM : 4GB (1 x 4GB)

My question is, what is the type of my RAM> Is it DDR3,or something else because my BIOS says it's LPDDR3 SDRAM and I searched up my model online and it is DDR3L, but from CPU-Z it's DDR3

Update : Nevermind I solved it myself, it is DDR3L
