Hi!      Quick silly question. I have 4GB, 2GB, and 1GB RAM Modules that I want to install in my Mac Pro Early 2007. I have the service manual so I know how to pair them on the risers but my question is:

Does it matter if I start with the 1GB Modules in the first slot then the 2GB pairs, then the 4GB pairs? Or is it better to start the 4GB pairs in the first 2 slots and work my way down in size? Or does it matter at all? I've been looking online for the answer and I can't seem find anything about it. Let me know if you know.  Thanks!
