Hi, I currently have a Dell Optiplex 780 DT and was wondering what specific type of ram I could use with it. Multiple sources have shown me varying answers an has sparked confusion upon me. So, I would like to ask for advice as to what ram I may use. As of now, all I know is that I need a DDR3 ram clocked at 1,333 Mhz. And what max capacity per DIMM slot may I use? Thanks!
