I'd like to upgrade the RAM memory on a Toshiba Satellite C55-B5115KM, which presently has a 4 GB card. The laptop specifications I have found for the card type are PC3-2800 or 8500 or 10600, DDR3L SODIMM 204 pin. I'd like to install a card I took from a Dell Inspiron N5110, which has 16 GB and its specifications are PC3-10600 DDR3 SDRAM SODIMM 204 pin. I have found a discrepancy in the information about the Tohiba laptop as to how much RAM it can use. Some site says 8 GB some says 16 GB in two cards. So my question is if what I want do is possible or if I can install 2 8 GB cards or limit it to 1 8 GB card or two 4 GB cards.
