Hello Christopher, and welcome to iFixit. I see this is your first question. Sadly the Acer C720 does not allow for you to upgrade your memory exclusively; however, you are able to upgrade the memory to a maximum of 4 GB by replacing the motherboard itself to a model with 4 GB. Follow the guide on the Acer C720 device page for replacing the motherboard.
