According to MacTracker and Datamem.com all of the Mac Pro models have  
4 or 8 RAM sockets. By my thoughts, it would be better to install RAM  
in matched pairs to get the best performance from them. That means  
that you would install equal value modules in the matching sockets in  
each bank, ie: Equal value modules in sockets A-1 and B-1 and the same  
for each pair of sockets until you run out of space or money.

I am wondering how you came to understand that either 3 or 6 RAM  
modules would be recommended.
