A system and method for configuring expansion bus links to generate a double-bandwidth link slot are disclosed. An information handling system includes a central processing unit (CPU) and memory operable to store program instructions executable by the CPU. A chip set operably couples the CPU and the memory to a first slot and a second slot. The chipset includes a root port that generates a first link coupled to the first slot and a second link coupled to the second slot. An adapter card is inserted into either of the first or second slots such that the adapter card routes either the first or second link to the slot not populated by the adapter card.
