  1. Hi Guys,

    I have a new p.c. and currently have a total of 1536mb of pc3200 (ddr400) crucial technology Ram. They are currently situated as follows,

    Slot 1 512mb
    Slot 2 512mb
    Slot 3 256mb
    Slot 4 256mb

    Is this the correct set up for dual channel?
    Would it be better if i had a different configuration like,

    Slot 1 512mb
    Slot 2 256mb
    Slot 3 512mb
    Slot 4 256mb

    Many thanks in advance.

    P4 3.2 PRESCOTT 800MHZ FSB
    MAXTOR 140 GB HD
    1536 MB PC3200 (DDR400)

    Take my advice with a grain of salt as they say, until someone who knows more corrects me... I thought that in order to have dual channel memory all the chips had to be the same size and type. I would look through your motherboard owners manual and see if it mentions memory configurations in it anywhere. I would also look at the boot up screen and see if there is a message about what mode the memory is currently operating in. Some motherboards report this information at POST.

    It would seem the 2nd configuration is better. If you open up the manual (yes, they do open like ordinary books ... ), in the memory section they explain why.


    The total amount of memory on slots 1 & 2 should be equal to the total amount of memory on slots 3 & 4.

    Many thanks for all of your swift replies,

    I have now reconfigured my ram as suggested,

    Now the post screen says that the ram is running in DUAL CHANNEL INTERLEAVED, Where as before it read just DUAL CHANNEL.

    What an excellent and informative resource site this is....

    Again many thanks guys..
