  1. Hi all and thanks for reading.
    I am selling my iXtreme x6618 to my dad so i can build my own pc to which the sith lord has been most helpfull ;)

    The pc has 4gig of dual ram in it and can handle 8gig max, so as a gift i want to up the ram to 6gig so i will buy 2x2gig modules and keep 2 of the 1gig in there.

    My question is the slots are blue yellow blue yellow. the ram is dual channel so how best should i put the different modules in

    example ?

    blue 2gig
    yellow 1gig
    blue 2gig
    yellow 1 gig


    blue 2 gig
    yellow 2gig
    blue 1 gig
    yellow 1gig

    ? odd question i know but wanted to ask if it mattered.

    btw the pc has Windows 7 ultimate 64 on it so would handle the 2gig upgrade.

    Thanks for any advice offered.

    i've been told by someone that the same company and the same stick value should be in the same colour slots, like:
    blue: 2gb
    yellow: 1gb
    blue: 2gb
    yellow: 1gb

    but im not sure about this, so wait for more responses

    When you're going to populate all 4 slots it wouldn't matter, except the the same color slots should probably be the same capacity.

    So, either of your "solutions" should work equally well.

    The system is going to assign the memory addresses, as to how it finds the RAM.

    The only consideration would be in the event of a differential configuration something like this;

    Slot 1; (the slot that must be populated) 512MB
    Slot 2: ( the other color of the pair) 512MB

    Slot 3 (the color matching slot 1) 1GB
    Slot 4 (then would be empty)

    This would net dual channel operation, with dissimilar DIMMS.

    Um yes, that's right.

    I'm somewhat immodestly going to re-quote myself and say "Um yes, that's right".

    You must have 3 GB in each pair of sockets (blue / yellow) The same value DIMMS should be in the same color sockets.

    That said, just do it like this, (first pair)

    Blue 2G
    Yellow 1GB

    then the next pair:

    Blue 2GB
    Yellow 1GB
