    Hi,

    Im now to order 8GB memory for my MacBook Pro, but I was just wondering.. Is there better to buy a KIT with 2x4GB together or is it the same if I just bought 2 singles (not as a kit)... Does it has something to do with the performance and dual-channel effect?

    The price is some higher on the kit, than buying two singles, thats why I had to ask! :)

    Would be happy with some answers on this.. Appreciate it! :)

    The kit has both modules in same package while singles come in two separate package :p The kit just has two exactly same modules in on package AFAIK

    I've done it both ways and haven't noticed any difference; ideally, you want both sticks to be the same manufacturer, latency, etc. Whether they are packaged together or not makes no difference I have ever noticed.

    You'll get the dual channel effect with 2 of the same brand and model/frequency. Sometimes kits are cheaper, but if you order 4gbx2 in singles, as long as they are the same brand/model, your fine.

    Then singles it will be :)

    Okay thanks for the info! :) I guess I have to go for the singles then, since it actually was cheaper than the kit :) Kind of weird, I also thought they would be cheaper but...

    When I got a kit, the serial numbers were sequential; I found that was nice.

    In reality I don't think there is really much of a difference; it's possible a memory OEM will switch chip makers (ie: Apple RAM can have Hynix, Micron, or Samsung chips) which with a matched kits would make sure both sticks are the same.
