[. . . ] Installing a PCI Express x16 Graphics Card 45 Intel Desktop Board DZ68BC Product Guide Removing a PCI Express x16 Graphics Card Follow these instructions to remove a PCI Express x16 graphics card from a connector: 1. Remove the screw (Figure 21, A) that secures the card?s metal bracket to the chassis back panel. Push the card ejector lever down using the tip of a pencil or similar tool (Figure 21, B) in the notch. Removing a PCI Express x16 Graphics Card Installing Linked PCI Express Graphics Cards The Desktop Board supports technology that allows you to install linked PCI Express graphics cards such as NVIDIA* SLI* (Scalable Link Interface) cards. Make sure you use two identical SLI-ready graphics cards that are NVIDIA certified and the latest graphics driver. You can use the connector included with the Desktop Board to connect the two graphics cards together. Consult the user documentation for your graphics cards or visit the NVIDIA GeForce* website (http://www. geforce. com/#/News) for more information on graphics card configurations. 46 Installing and Replacing Desktop Board Components To install two linked PCI Express graphics cards: 1. Install the first card in the PCI Express x16 connector as described in ?Installing a PCI Express x16 Graphics Card?Place the second card in the secondary PCI Express x16 connector (Figure 22, A) and press down on the card until it is completely seated in the connector and the card retention notch on the card snaps into place around the retention mechanism pin on the connector. Secure the card?s metal bracket to the chassis back panel with a screw (Figure 22, B). Connect the two cards together with the SLI bridge (Figure 22, C) as shown. Table 10 shows the pin assignments and signal names for the front panel CIR receiver (input) header and Table 11 shows the pin assignments and signal names for the back panel CIR emitter (output) header.
