Random Access Memory (RAM)

Correct Answer: Add another 8GB DDR4 RAM module

The most cost-effective way to improve performance is to add another 8GB DDR4 RAM module. Adding a second 8GB RAM module will allow the system to utilize dual channel memory, increasing the overall performance significantly.

Correct Answer: Run a memory diagnostic tool

When troubleshooting a system experiencing frequent crashes during high workload tasks and suspecting a RAM issue, the first step should be to run a memory diagnostic tool. This will help identify any problems with the installed RAM modules, such as errors or failures. The diagnostic tool can pinpoint specific issues and confirm if the RAM is the root cause of the crashes. Replacing the graphics card or reinstalling the operating system would not directly address the suspected RAM issue and should be considered only after ruling out RAM problems. Replacing the RAM modules without first diagnosing the issue may be premature and could be a waste of time and resources if the RAM is not actually faulty.

Correct Answer: DDR4 operates at lower voltages and higher speeds than DDR3

DDR4 operates at lower voltages and higher speeds than DDR3 is the correct answer. DDR4 RAM is an improvement over DDR3 in several ways: 1. Lower voltage: DDR4 typically operates at 1.2V compared to DDR3's 1.5V, resulting in lower power consumption and heat generation. 2. Higher speeds: DDR4 supports higher clock speeds, starting at 2133 MHz and going up to 3200 MHz or more, while DDR3 typically ranges from 800 MHz to 2133 MHz. 3. Increased efficiency: DDR4 has improved signal integrity and reduced crosstalk, allowing for better overall performance. The other options are incorrect: DDR3 does not have a higher maximum capacity per module compared to DDR4. In fact, DDR4 supports higher capacities, with modules up to 64GB or more, while DDR3 modules are typically limited to 16GB or less. DDR4 does not use the same pin configuration as DDR3. They have different physical layouts and are not compatible with each other's slots. DDR3 does not support higher clock speeds or lower latencies than DDR4. While DDR3 can have lower latencies in some cases, DDR4 generally offers higher clock speeds and overall better performance.
