    How do notebooks (im assuming they all have a maximum of 2dimm) have 3gb of ram?

    I thought memory can only come in either 512mb, 1gb, 2gb or 4gb modules. How can you get a sum of 3gb out of these?

    I think youve confused Double Data Rate with Dual/Single Channel

    I suggest you check wikipedia and the RAM guide

    On Intel systems, dual channel will only be ever so slightly reduced by mismatched sizes.

    Actually 32-bit can see 4GB, it just can't utilize it since there is overhead.
