Memory, otherwise known as RAM (random access memory) is short term storage that stores data and machine code that's currently being used. The more your system has, the easier it is for your computer to run multiple operations and multi-task. Larger software applications like 3D design software, photo editing suites, etc. run better with more RAM. It comes in many form factors, speeds and capacities. You can even buy it with lights and cool designs to help your system look good. Make sure the one you choose is compatible with your motherboard and doesn't exceed it's limit. We can help!
