Right now I have 2x512mb 5300 ram. I am wanting to get 2gb, but I don't know if I should get 2 more 512 sticks or get 1 1024 stick. I don't really care for dual channel. I did a Crucial.com computer scan and it said my memory must be in matched pairs. I don't really believe this. Anyway, would it make more sense to get 1x1024 stick instead of 2 more 512? I do plan on upgrading my ram later on. Sorry if this question has already been asked.
