Good day, I have an asus x415EP notebook and im looking to upgrade its ram. Currently I have 8GB DDR4 3200 accdg to windows system. At first I downloaded CPU Z to check how many slots i have for expansion, so i have the 8gb in slot1(* edit: 4GB in slot 1) and nothing for slot 2...before i decided to get a 32gb upgrade online, i opened the back panel of the notebook and saw a 4GB installed in the only slot i saw available....does this mean i can only have a maximum of 36GB here? or am i not seeing another empty expansion slot at the back?
