Sorry for the newbie questions but I'm a little confused right now.
I want to install a little extra RAM so opened up my computer to check exactly whats already in there. There are 2 empty slots, and 2 sticks both with model number NANYA NT5TU128M8DE-AD for which it says online are both 1GB DDR2. But.... According to DXDiag or my computer's properties I have 4gb. So first of all where are the other 2gb?
Second question is, if I already have 4GB is it possible to add another 4GB? I'm not sure the make or model of my motherboard but the PC I have is http://www.pcworld.com/product/30456/dell-optiplex-755.html (I know it also says it comes with 2gb on the specs but the previous owner had upgraded some stuff so I assume also the RAM.)
