Oh really? So i could put the full 4gb but only get 3.3gb used out of it? Well that would be fine with me! Yes i read that apple doesnt recommened a 1gb and 2gb stick because they want you to stay dual channel to be used with your vid card anyways thanks for that great info! I will not be going 4gb for sure!
Did you purchase yours from OWC? Or if not how much and where?
FYI - this is only true for newer minis. The issue is that the mainboard controller can only physically access 3.3G. HOWEVER if the mini is the older Core Solo or original Core Duo there is a firmware limitation of 2G.
If you want more then 2G, you will need a Core 2 Duo machine.
