The A8N-SLI Deluxe offers two PCI Express slots used for graphics cards and two PCI Express x1 slots. Here, the two PCI Express x16 slots are colored. In SLI mode, the user should always remember that the graphics card is connected to the blue PCI slot which should be considered as the primary VGA card that will handle all signal transfers to the monitors. The secondary card (black slot), is used only for graphics acceleration. The monitor connected to the secondary VGA card will go blank in SLI mode.
In order to switch from single VGA mode to SLI mode and vice-versa, the A8N-SLI Deluxe uses a small interface card that needs to be inserted accordingly. Looking at the picture below, notice the indications on the inserted card for "Single Video Card" and "Dual Video Cards". This card is removed and inserted in the correct direction depending on the mode desired. You also need to be wary of the fact that despite there being an option in the motherboard's BIOS to enable/disable SLI mode, the interface card still needs to be inserted correctly.
