What type of memory configuration utilizes two memory modules to increase performance?

Dual-Channel memory configuration utilizes two memory modules to enhance performance by improving the data transfer rate between the memory and the memory controller. This configuration effectively doubles the available memory bandwidth by allowing two memory channels to operate simultaneously, thereby allowing higher data throughput compared to a single-channel setup.

In a dual-channel configuration, when matched pairs of RAM sticks are installed—meaning they have the same capacity and specifications—the memory controller can read from and write to both modules at the same time, which leads to better performance, particularly in memory-intensive tasks like gaming or video editing.

While single-channel, triple-channel, and quad-channel configurations exist, they do not represent the same benefit when it comes to performance enhancement through the use of just two memory modules. Single-channel uses only one path for memory data, whereas triple-channel employs three and quad-channel uses four, which increases performance but requires more than two modules to function properly. Therefore, dual-channel stands out as the correct choice for utilizing two modules to boost system performance.
