Build your own PC

Thinking of building your own rig? It’s a great way to get exactly what you want in a system.

Before you start, consider your motherboard’s technology. Is it DDR3 or DDR4? How many DRAM slots are available on the motherboard? Do modules have to be installed in pairs, triplets or quads? At what speed do you want your memory to perform? Do you need DIMMs or SO-DIMMs?
