    Mixing ram sizes in new pc.

    Hi everyone. I bought a new pc a few months ago with 2x2GB of ram. Could I install a 1x4GB if the speed is the same? I'd be using the same make which is this:

    scan.co.uk/pro…50v

    The reason I would be using 1x4GB and not 2x2GB is because the heatsink for the CPU covers one of two remaining slots meaning iv only got one to work with.

    Are you currently using slots 1 & 3 for the 2gb sticks?

    Are you currently using slots 1 & 3 for the 2gb sticks?



    how can he be if the last 2 slots are covered up?

    Yes that would work but wouldnt be as good as 2 x 2

    I disagree. Surely this should be the current setup:

    Slot 1 - 2gb
    Slot 2 - Empty
    Slot 3 - 2gb
    Slot 4 - Blocked

    You would usually want the matching pair to be in 1 & 3 to run in dual channel mode.
    If you then put a 4gb stick in slot 2 would you lose the dual channel on the existing pair?

    Need a techi but as far as I know as long as the speeds are same than there will be an improvement (the speed is taken from the lowest running ram stick)

    Remember, some OS do not recogniseRAM above a certain amount

    That's a good point, I take 64bit for granted these days
