Can i add memory to my NVIDIA GeForce 7100 NVIDIA nForce 630i?

Answer 1

You have mentioned both a graphics card and a motherboard there. You can add memory to the motherboard in the form of RAM sticks, but you cannot add memory to the graphics card. You can "trick" the computer into thinking it has more memory by allotting space oh the hard disk to be used for graphics memory but this will decrease performance as the hard disk is much slower and is generally not reccomended
