VRM may refer to any of the following:
1. Alternatively called a processor power module, VRM is short for voltage regulator module. It is either embedded into the motherboard or a separate, small circuit board that regulates and supplies the correct voltage to the processor. Using a VRM, AMD and Intel can adjust the power to the processor instead of requiring the power supply to supply the correct current. One of the first motherboards to have a VRM was motherboards using the Socket 7 socket.
2. VRM is an abbreviation sometimes used for video RAM (random-access memory).
