Sorry that motherboard does not support the new core2duos.The motherboard installed in the demension e520 is an older version

SOURCE: Upgrade

Because of the shear numbers of Dell models and #'s of motherboards, my safest suggestion to you is to go to the web-page I will place below and have dell analyze your computer.
By doing this you are allowing the manufacturer to see what they supplied you with, then they will tell you after the analytical test just what you can or cannot do with your motherboard.
Its easy do it right first time and you won't go wrong, if you are not happy with the results, use the support number to call a service center and ask a tech. I am say this as this can be an expensive mistake you will not thank anyone for.
