Hello all, long time Mac user, first time iMac owner here! Finally bought myself the 21.5" iMac and a 2x4GB RAM upgrade yesterday, going to install them tonight, and I was wondering if there is a specific way to place the two new sticks in for best results? To use the PC comparison, usually motherboard DIMM slots are AB|AB, so I would put the 4gb DIMMs in A1 and A2, and 2gb modules in B1 and B2. I know the iMac slots are instead on top of each other, so is there a correct way to configure these? Bonus question, I also have a 500gb Firewire 800 drive coming to use with Logic 9, anyone have any tips on how best to configure Logic so it writes everything to that drive, and keeps the main drive clear for best performance? I'm coming from working in Windows and Pro Tools, which is about as far away from Apple methodology and workflow as you can get. I watched a lot of the Lynda.com Logic 9 stuff back when it came out, and what I do remember is that everything is a little easier and more intuitive, just like most Apple software. Thanks in advance!
