What ram do I need?

[sagunzo216]

I have a Dell Optiplex 7010 I5 3470 MT. I wanted to upgrade the ram from 4gb to 8gb. What specific type of ram would I need to add to the computer and where is the cheapest place to get it? Any help would be appreciated.

I believe the ram already installed is 4gb ddr3 1600
