How to Identify RAM Chips
Random access memory (RAM) chips, or RAM modules, are units of physical memory that plug into a computer's motherboard and send data to the CPU, to allow a computer to run. The amount of RAM you have installed on your system can affect your ability to run programs; in general, the more RAM you have, the more you will be able to multitask without experiencing lag. If you plan to upgrade your RAM, or simply wish to know what type of RAM your computer is using, there are several ways to identify RAM.
