A system board has six slots for memory chips, aligned in two banks. Which of the following is the optimal memory configuration this board supports?

Multi Mode is not a standard or recognized memory channel configuration terminology in system board specifications.

Dual-channel memory requires pairs of matching DIMMs across two channels; a board organized into two banks of three is not optimized for dual-channel operation.

Triple-channel memory uses three modules simultaneously to increase memory bandwidth - a board with six slots in two banks of three is specifically designed to run three DIMMs per bank in triple-channel mode, making this the optimal supported configuration.

Single-channel uses only one memory module and represents the minimum rather than optimal configuration for any multi-slot board.
