i want to upgrade my ram... my dell xps 8920 came with 2 8gb ram sticks...i wanted to upgrade to another 16gb...but do i get 2 8gb sticks or could i go with just 1 16gb stick? idk know if it makes a difference but i heard you should go with what your pc game with..i used crucial.com to get a diagnostics of ram sticks that are compatible with my pc
