What is the bus speed of DDR3-1600 memory?

533MHz
667MHz
800MHz
1066MHz

The correct answer is: 800MHz

DDR3-1600 memory has a speed of 1600MHz, which is also known as the clock speed or frequency. This is the actual operating speed of the memory and determines how quickly it can transfer data. The options A, B, and D have lower frequencies and are therefore incorrect. Option C is the closest match to the actual speed and is the correct answer.
