What types of RAM cards are there?
What are the different sizes of RAM cards? Physically I mean. I need to buy new RAM cards for my PC (tower) and am wondering what type of cards I need.
If you do not know what kind of Ram you have you can run CPU-Z and that will show you what you are running now. If your system is not working because of bad ram give us the make/model motherboard because there is several types of ram from very old SD-Ram to DDR3 it is hard to the what you need with out that.
