Memory Installation Order

When I got my new Power Mac G5, I got an extra 2G of memory along with it as a separate purchase to install myself. Reading the manual, I see that it says to install any new memory AFTER the existing set of 2 * 256 my Mac came with.
For whatever reason, when I installed my memory, I took the original 2 * 256 out, installed my 2 * 1G in the slots the original memory was in, and then put the original memory in the next slots. I thought that the machine might perform better if the first 1GB or so was all on the same chip set.
Now I am wondering, is there a reason for Apple's injunction to put any new memory after the original 2 * 256, not instead of it? Is that first set of memory slots special in any way? How about the memory itself? I am assuming it is the same speed and width as any other compatible memory for this machine. Am I wrong?
By the way, my Mac happily shows that it has 2.5 GB of memory, so all my memory is being recognized. I am just always hunting for new ways to make it ever faster!My Macs: iMac 27" 3.4 GHz, Mac Pro 3.2 GHz, PowerMac G5 Quad 2.5 GHz, G4 Cube with 1.2 GHz Upgrade

Try doing a benchmark test with XBench and then do the same with the memory swapped around. I shouldn't think that you will find much of a difference so long as the new memory that you purchased was a good make but you never know.
