    Am I right in thinking that the two 4gb sticks should be in slots 1 and 2, and the 1 gb apple supplied sticks in 3 and 4?

    I don't think it matters as you match 1-2 and 3-4.

    This is usually the way it works in the PC world. I'm going to be doing the same exact upgrade soon. I'll probably put the 2x4GB sticks in 3 & 4, run geekbench, then put them in 1 & 2, and run geekbench again. Then go from there.

    I put the the 4GB sticks in slots 3 and 4 and when I booted up the computer the RAM utility popped up and said that for optimal performance I need to put the 4GB sticks in slots 1 and 2 and 1GB sticks in slots 3 and 4. Hope this helps.
