2.7.1.3 Installing Four SLITM-Ready Graphics Cards

Step 1. Install identical 4-Way SLITM-ready graphics cards that are NVIDIA® certi- fied 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 goldfingers 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.

Two Goldfingers

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.

Step3. Align and insert an ASRock SLI Bridge Card to the goldfingers of the first and second graphics card. Install the second ASRock SLI Bridge Card to the goldfingers 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 firmly in place.
