What memory do I need?

[Holly6330]

Hello! I am trying to figure out what exact memory I need to purchase for my All in One computer. I know I need 8gb. But I need specifics to make sure I am going to purchase the correct item.  I went through the virtual agent and it said to check the mother board specs... but it wont show.  It says oops!
