This article explains what motherboard RAM slots are, why they are used, and how to use them.
Which slots should I put RAM in? 1 minute discussion!
RAM slots are often found in pairs and are sometimes color-coded for identification. It should be noted that RAM slots in a desktop computer look different than RAM slots in a laptop. A RAM module is rectangular and has a connector on one of its long sides.
RAM slots or sockets on a PC motherboard are long channels, usually located close to the CPU. There are clips on each end of the socket, which snap tightly around the edge of the RAM when inserted. Pushing the RAM into the socket engages these clips, so they must be disengaged before you can remove the currently installed RAM. Typically, you push the clips away from the memory module, and they help to disconnect the module from the motherboard.
Typically, motherboards have a total of 4 RAM slots, or two pairs if they are dual-channel. Some high-end motherboards can have as many as eight slots, and in supercomputers, there can be multiple motherboards per system, up to 32 slots in total.
