Random Access Memory (RAM)

Correct Answer: DDR (Double Data Rate)

DDR (Double Data Rate) RAM is the correct answer because it uses two data transfers per clock cycle. DDR RAM technology is designed to transfer data twice per clock cycle, effectively doubling the data transfer rate compared to older RAM technologies. This is achieved by transferring data on both the rising and falling edges of the clock signal. SDR (Single Data Rate) RAM only transfers data once per clock cycle, making it slower than DDR. QDR (Quad Data Rate) RAM is not a commonly used technology in consumer-grade computers and is not part of the standard RAM types covered in CompTIA A+. GDDR (Graphics Double Data Rate) is a specialized form of DDR RAM used primarily in graphics cards. While it does use double data rate technology, it is not the general-purpose RAM technology referred to in the question.

Correct Answer: Monitor the system's temperature and stability during the overclocking process.

When overclocking RAM, it's crucial to monitor the system's temperature and stability. Overclocking can cause increased heat generation and potentially lead to system instability if not done properly. Keeping an eye on these factors helps ensure the process is successful and safe for the hardware. Purchasing additional RAM slots and spreading the memory load is not necessary for overclocking and may not be possible on all motherboards. While removing dust from RAM sticks is a good general maintenance practice, it's not directly related to the overclocking process. Disabling virtual memory settings in the operating system is not required for overclocking and may negatively impact system performance.

Correct Answer: Upgrade to at least 8GB of DDR3 RAM.

Increasing the RAM capacity to at least 8GB with DDR3 will provide more memory for applications, reducing crashes and errors. Other options may not be compatible, don't provide enough memory, or are unrelated to the memory problem.
