In the context of RAM, what does overclocking refer to?

Overclocking in the context of RAM refers to running the RAM at higher speeds than it was designed to operate. This process involves adjusting the settings so that the RAM modules function at a frequency that exceeds their rated specifications, which can enhance performance in certain tasks that are sensitive to memory speed, such as gaming or running memory-intensive applications.

When RAM is overclocked, it can lead to improved data transfer rates and reduced latency, potentially resulting in faster overall system performance. However, it is essential to ensure that the system's motherboard and CPU support the higher speeds and that proper cooling measures are in place, as overclocking can lead to overheating and instability if done incorrectly.

The other options listed do not accurately describe overclocking in the traditional sense, as they focus on lowering speeds, increasing capacity, or changing clock frequencies in ways that do not align with the concept of pushing components beyond their rated performance levels.
