At what voltage does DDR4 RAM typically operate?

• A. 1.2 volts
• B. 1.5 volts
• C. 2.5 volts
• D. 3.3 volts

Answer: (A)

DDR4 RAM typically operates at a voltage level of 1.2 volts, which represents a significant reduction compared to its predecessor, DDR3, which operated at 1.5 volts. This lower voltage is part of the design of DDR4 to enhance energy efficiency and reduce power consumption, making it more suitable for higher-performance applications while maintaining lower thermal output. The transition to 1.2 volts allows DDR4 to deliver better performance and higher speeds without the increased power demands, thus enabling more efficient operation in modern computing environments.
