The setting of these jumpers determines the operation mode of PEX16_1 and
PEX16_2. If you want to use the CrossFire function, these jumpers should be
set to Pin 2-3 close; and PEX16_1 and PEX16_2 will both run with x8 speed. If
these jumpers are set to Pin 1-2 close, PEX16_1 will run with x16 speed and
PEX16_2 will not be functional.
