CompTIA A+ Core 1 (220-1101) — Question 130

A user's device needs more memory, so a technician installs extra RAM with the following specifications:

2 x 8Gb DDR3-1066 (PC3-8500)
1 x 16Gb DDR3-1333 (PC3-10600)

Which of the following speeds would maximize reliability?

Answer options

• A. 1,066
• B. 1,333
• C. 8,500
• D. 10,600

Correct answer: A

Explanation

Choosing the speed of 1,066 MHz ensures that all RAM modules can operate stably together, as the slowest RAM dictates the overall speed in a mixed configuration. The 1,333 MHz module would be downclocked to match the 1,066 MHz speed, potentially causing issues with stability. Therefore, using the lowest common speed maximizes reliability.
