I have a Dell Latitude D510 that has 2 512mb ram sticks in it. I have to check, but I am sure I have a few 1gm ram sticks in my stash. My question is, would I be able to replace the 2 512mb ram sticks with 2 1gb ram sticks? I know most pc's and laptops can be upgraded to newer stuff, but I think I read somewhere before, that they all have a max that they can go to as well. So thought I would ask.
