    PCIe x16 slot


    Hi,
    There's a graphic card that I want to purchase, but my system is not very advanced and I'm not sure that the motherboard has the required slot for it.
    The graphic card requires a PCIe x16 slot.

    I attached a photo of the lower section of the motherboard, could someone tell me if one of the available slots is a PCIe x16?
    Thanks.

    Using a PCIe x1 card in a PCIe x16 slot


    Here is something I recently found out. I have tired this and it works.

    You can use a PCIe x1 card, or a PCIe x4 card in a PCIe x16 slot. They work fine. So if you think you are short of PCI-e slots, you may not be. A shorter PCIe card works fine in a longer slot.

    On PCIe X1, X4 and X16 slots, the first 18 pins are all wired the same, so as long as the PCI-Express card fits in the PCI-Express slot, it should work.

    This is not the case for the legacy PCI (32-bit, non-express) slots, that are not PCI-Express. Those are not compatable with PCIe cards.

    Picture of assorted PCIe and PCI slots.

    The top four slots, in the picture above, are, from the top to bottom,
    PCIe x4 slot , PCIe x16 slot, PCIe x1 slot and another PCIe x16 slot. A PCIe card that can physically fit in any of these slots will work, even if it doesn't fill the entire slot.

    The bottom, 5th slot, is a PCI legacy (32-bit) slot. PCIe (express) cards will not work in this slot. It only accepts legacy PCI cards.

    Here is the PCI-Express page on Wikipedia showing pinouts, etc.
