CompTIA A+ Core 1 (220-1001) — Question 340

A customer has two 8GB sticks of 2400-speed DDR4 installed in slots 1 and 2 of a computer and wants to add more RAM. The customer purchases two additional
4GB sticks of 3200-speed DDR4 and installs then in slots 3 and 4. While installing the RAM into the board, the user notices the board has `quad channel` etched near the RAM slots.
Which of the following can be said about the user's channel configuration after upgrading the RAM?

Answer options

• A. The computer is utilizing one channel.
• B. The computer is utilizing two channels.
• C. The computer is utilizing three channels.
• D. The computer is utilizing four channels.

Correct answer: D

Explanation

After installing the additional RAM, the computer has a total of 32GB across four slots, which allows it to utilize the quad-channel configuration. This means it is operating on all four channels effectively. The other answers are incorrect as they do not account for the total RAM and channel capability of the motherboard.
