fi ed because different types of graphics cards will not work together prop-
erly. (Even the GPU chips version shall be the same.) Each graphics card
should have two goldfi ngers for the ASRock SLI Bridge Card connectors.
Insert one graphics card into the PCIE1 slot, another graphics card into the
PCIE3 slot, the third graphics card into the PCIE5 slot and the last graph-
ics card into the PCIE7 slot. Make sure that the cards are properly seated
on the slots.
Step2. Connect the auxiliary power source to the PCI Express graphics card.
Please make sure that both power connectors on the PCI Express graph-
ics card are connected. Repeat this step on the other graphics cards.
Step4. Connect a VGA cable or a DVI cable to the monitor connector or the DVI
connector of the graphics card that is inserted to PCIE1 slot.
Two Goldfi ngers
Step3. Align and insert an ASRock SLI Bridge Card to the goldfi ngers of the fi rst
and second graphics card. Install the second ASRock SLI Bridge Card to
the goldfi ngers of the third and fourth graphics card. Connect the second
and the fourth graphics card with the ASRock SLI_Bridge_3S Card. Make
sure the ASRock SLI Bridge Cards are fi rmly in place.
