2.7.1Graphics Card Setup

2.7.1.1 Installing Two SLITM-Ready Graphics Cards

Step 1. Install the identical SLITM-ready graphics cards that are NVIDIA® certified because different types of graphics cards will not work together properly. (Even the GPU chips version should be the same.) Insert one graphics card into the PCIE1 slot and the other graphics card into the PCIE3 slot. Make sure that the cards are properly seated on the slots.

Step2. If required, connect the auxiliary power source to the PCI Express graphics cards.
