Hi,
My laptop is an Aspire E5-521-68N4 (it also has Aspire E 15 written near the model number, so not sure if it matters). When I search out a RAM (want to upgrade RAM to 16GB) in Amazon I unable to find an exact model match the best I have seen is E5-521-68NT and when I state it as Aspire E 15 E5-521 (can't even get close to using the 68N4) the closest match I get is Aspire E 15 E5-523 series. Can someone help with what I might be getting wrong or how to go about addressing this. I would like to upgrade to 16GB RAM, SSD drive and if possible a higher processor as well. Any help is most welcome. Thanks in advance.
