    I have currently got 512MB DDR Ram and have another module of 512MB SDR Ram,
    so my questions are:
    1.) Is it possible to have both SDR and DDR running alongside in same
    2.) Would the system recognise and use both RAM modules?

    My spec is:
    512MB DDR
    80 Gig HD
    Sis 645 Motherboard
    OS: Win XP Professional.

    Thanks in advance.

    It is I believe usual, that you can *not* use both types of memory at the
    same time.

    Not with a SiS based motherboard. Matter of fact, I don't know ANY
    P4 chipsets that support both simultaneously ... but there might be.
    See above ...
