Q: Hi. I do not understand how this works. Say i will purchase a motherboard "nForce 780i" which is a DDR2 and i want somekind of nvidia graphics card like 9600 GT. In 9600 GT's description(specification) it says that "Memory type: DDR3" so does that mean that these two components cannot work together? PLZ help. Thx
A: No, they will work together just fine. The motherboard only supports DDR2 memory and the graphics card has DDR3 memory. But you're not going to connect the graphics card's memory to the motherboard, you're going to connect it to the graphics card. The graphics card having DDR3 memory is just a "gee whiz, how cool" specification. It is purely internal to the card and has no effect on its compatibility. The motherboard's memory specification, however, is a compatibility specification. It is telling you want kind of RAM you can connect to the motherboard for system memory.
