Since only one memory module is utilized per channel in a single-channel setup, bandwidth & overall performance may be constrained. Dual-channel setups, on the other hand, enablesatta..king two memory modules to function concurrently, thereby doubling the speed at which data is transferred between the CPU and the RAM. This configuration is especially helpful for activities like gaming and video editing that demand a lot of memory bandwidth. Four memory modules can cooperate in quad-channel configurations, which further develops this idea.
