RAM Type and Configuration?

Hello!

My Question has 3 parts.

a) MUST the iMac Mid-2007 20" EMC 2133 use PC2-5300 or will it run the PC2-6400?

b) I believe it will run up to 6GB of RAM, although not officially supported by Apple?

c) Must both slots carry equal amounts of RAM, eg. 2x2GB, 2x3GB, or can I configure unevenly, eg. 1x4GB + 1x2GB, 1x2GB + 1x1GB, etc.

Thanks!
