What occurs when RAM speeds are mismatched in a dual-channel configuration?

In a dual-channel configuration, when RAM speeds are mismatched, the system defaults to the speed of the slower module. This means that both memory modules will operate at the speed of the slower one in order to maintain system stability and ensure compatibility between the two modules. This approach helps to prevent potential issues that could arise from trying to operate both modules at different speeds, which could lead to instability or crashes.

The system takes this approach to ensure that all channels can communicate effectively without bottlenecks or misalignments in data transfer rates. As a result, while the full potential speed of the faster module is not utilized, the dual-channel configuration can still provide benefits over a single-channel setup, such as increased bandwidth, as long as the modules adhere to the same operating speed.
