2.7.1.2 Installing Three SLITM-Ready Graphics Cards

Step 1. Install identical 3-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 3-Way SLI Bridge connector. Insert one graphics card into PCIE1 slot, another graphics card to PCIE3 slot, and the other graphics card to PCIE5 slot. Make sure that the cards are properly seated on the slots.
