Embodiments of the present invention include methods for increasing off-chip bandwidth. The method includes designing a circuit of switchable pins, replacing a portion of allocated pins of a processor with switchable pins, connecting the processor to a memory interface configured to switch the switchable pins between a power mode and a signal mode, providing a metric configured to identify which of the power mode and the signal mode is most beneficial during 1 millisecond intervals, and switching the switchable pins to signal mode during intervals where the signal mode provides more benefit than the power mode.
