What does "memory overclocking" refer to?

Memory overclocking refers to the practice of running RAM at speeds higher than its rated specifications. This means configuring the memory modules to operate beyond the standard frequencies defined by the manufacturer, which can result in improved performance in various applications, especially in gaming or high-intensity computing tasks.

Overclocking often involves adjusting the voltage and timing settings of the RAM, which can lead to increased data transfer rates and reduced latency. While this approach can boost the overall system performance, it also involves risks, such as potential overheating and system instability if not handled correctly. Thus, enthusiasts who pursue memory overclocking typically monitor temperatures and system behavior closely to ensure stability and longevity of the hardware.

The other options describe unrelated concepts. Lowering RAM speeds conserves energy but does not qualify as overclocking; running RAM at standard speeds is the default behavior; and increasing the storage capacity of RAM pertains to upgrading the physical amount of memory rather than adjusting its speed.
