When two memory modules are not configured to run in dual channel mode, the correct approach is to move the modules to the appropriate motherboard slots. Most motherboards require specific slots to be used together in order to enable dual channel operation. Typically, this means that the modules should be installed in matched slots that are often color-coded (for instance, both in the slots of the same color).

If the memory modules are installed in non-matching slots, the system may revert to single-channel mode, which can reduce overall memory bandwidth and performance. By relocating the modules to the designated slots, dual channel mode can be activated, optimizing the performance of the system.

Replacing both memory modules or installing additional modules is unnecessary if the existing modules are functional and compatible. Updating the BIOS settings is also not a typical requirement for switching to dual channel operation; rather, it’s primarily a matter of ensuring physical installation in the correct slots.
