Can I add 512MB DDR PC2700 to a computer that has 256MB DDR PC2100?

Q: I have an old P4 desktop that had 256MB DDR PC2100 ram. Can I mix it with 512MB DDR PC2700 ram or will it cause a problem? It runs on Windows XP.

    The computer should be able to handle having both of those sticks of RAM installed.

    When mixing RAM that can run at different speeds (PC2100 and PC2700) the computer will compensate for this by running all the RAM at the speed of the slowest stick. RAM speed isn’t anywhere nearly as important as having a decent amount of RAM installed, so toss the memory in there and you should be good to go.
