I have a question about which stick of RAM to put into which RAM slot. I recently ordered 2 - 1GB sticks of RAM but then changed my order to just 1 - 1GB stick of RAM. I decided to keep the 512MB from Apple in there and just upgrade to 1.5GB of RAM. I installed the memory tonight and it works fine.....but I put it into the 2nd slot. Should I take the Apple 512MB RAM stick out of the first slot (that it came in) and put the 1GB stick there and the 512 in the 2nd? Is there any benefit to having the larger amount of RAM in the first slot? I was just curious and wondered if the Mac would first look to the first slot before going to the 2nd for memory. Thanks!
