Hey,
i currently have a mere 1gig of ram and recently purchased a furthur 2 1gig chips. i'm running ddr2 so was wondering if i could dual my two new chips as well as use my old chip?
You might want to include things like the mobo model and the RAM models. Without any additional information I would say yes. Additional information would get you a more complete response.

Im not sure what youre asking. If its whether you can run new sticks along with the old one - theres pretty good chance for that. If its whether you can run them in dual-channel mode, than - no(parity required: 2 or 4 identical sticks)
