Very interesting.... The graphics card has a bearing on how much memory can be seen. Never knew that! I can see my 3gb with an x1900XT, wish i could try 4gb.

All PCI devices do since they require memory addresses for accessing their registers, etc, I just didn't think it would have this much of an affect.
