So the linked diagram would be correct for a 2.66 MacPro, right? I ask because that is what I have and the Apple Genius has me keep the 2X512k in riser A and the 2X2GB under them in riser B. That diagram shows the 2X2GB in riser A with the smaller memory below. Would this be better to put the big sticks in riser A then?
Perhaps this is where my question should go:
