Choosing an expansion card slot Whenever possible, use the following tips to help you select the proper slot for an expansion card: ● Use the black PCIe x16 I/O slot for the primary graphics card; if you do not use this slot for the graphics card, only cards certified as After Market Options are supported. ● Insert a second graphics card in the white PCIe x16 slot. ● Install a card in a slot that most closely matches its interface technology: ◦ Install a PCIe Gen1 x16 or a PCIe Gen1 x8 card in the PCIe Gen2 x16 slot. ◦ Install a PCIe Gen1 x4 card in the PCIe Gen1 x4 slot. ◦ Install a PCIe Gen1 x1 card in the PCIe Gen1 x1 slot. ◦ Install a PCI card in one of the PCI slots. ◦ Whenever possible, install a PCIe x1 card in an x1 slot. ● Leave as much space as possible between cards. ● For best operational efficiency, select a slot that: ◦ Electrically matches the number of PCIe card lanes (e.g., x1 in a x1 slot). ◦ Has more lanes electrically. ◦ Has fewer lanes, but is closer to your needs. For example, place an x16 card in an x4 slot, and an x4 card in a an x1 slot. ● An x1 connector supports an x1 card only. Although, an x1 card can be inserted into any slot, this may waste the potential for future card placement. ● To prevent electromagnetic interference, avoid installing a card with external cable connections next to a graphics card.
