    Default Gigabyte H97-HD3 and PCIe slots

    Hello,

    I'm having issues with the Gigabyte H97-HD3 I just bought, regarding the PCIe slots of the motherboard.
    It has :
    - a PCIe 16 x16 slot
    - a PCIe 16 x4 slot
    - two PCIe 1 x1 slots
    - two PCI slots

    Okay, so I have my GPU in the 16 x16 slot. My capture card in the 16 x4 slot. And my sound card in one of the 1 x1 slots. Now I am positive my 3 cards are working, correctly inserted and connected to the power supply. My PCIe x1 slots aren't working. My sound card isn't detected. I tried both slots, both are giving me no results. No card in device manager, and there's nothing about the PCIe slots in the BIOS. Could it be this motherboard can't power the x1 slots when the two others are used? Is that even a thing?
    Or am I doing something wrong?

    Could someone provide me some information, or should I just return the motherboard and get another one, with actual working PCIe slots you can actually use, and aren't there just for show?

    I would be very grateful. Thank you for your time.
    Regards,

    Welcome to the forum.

    From the Gigabyte specifications for your motherboard:

    1. 1 x PCI Express x16 slot, running at x16 (PCIEX16)
      (The PCIEX16 slot conforms to PCI Express 3.0 standard.)
      * For optimum performance, if only one PCI Express graphics card is to be installed, be sure to install it in the PCIEX16 slot.
    2. 1 x PCI Express x16 slot, running at x4 (PCIEX4)
      * The PCIEX4 slot shares bandwidth with the PCI Express x1 slots. The PCI Express x1 slots will become unavailable when a PCIe x4 expansion card is installed.
      * When installing a x8 or above card in the PCIEX4 slot, make sure to set PCIE Slot Configuration (PCH) in BIOS Setup to x4.
    3. 2 x PCI Express x1 slots
      (The PCIEX4 and PCI Express x1 slots conform to PCI Express 2.0 standard.)
    4. 2 x PCI slots
    You will need to use a higher end motherboard where you can use all of the pci-e slots at the same time.

    Shoot! I ended up sending it back and getting an MSI instead. Somehow, despite it being a cheaper motherboard, everything's working well now.
    Thank you for the information you gave me, ProfJim. (And for the warm welcome.)

    One could wonder why they do add PCIe slots if you can't use them all at the same time. Feels like a waste.

    You're welcome, glad to help out.

    My best guess is that it is a cost saving measure.
    The MSI H97 PC Mate motherboard does not have any pci-e restrictions.

    Even high end motherboards have some sort of restrictions.
    As you've learned the hard way, before you buy any motherboard you need to check the detailed motherboard specifications in the user manual and/or on the motherboard model's webpage.

    FWIW, I found that MSI has three H97 based motherboards that have two x16 pci-e slots along with two x1 pci-e slots.
    From the MSI H97 GAMING 3 specifications:
    Slots
    1 x PCIe 3.0 x16 slot (PCI_E2, supports x16 speed)
    1 x PCIe 2.0 x16 slot (PCI_E4, supports x4 speed)*
    2 x PCIe 2.0 x1 slots
    3 x PCI slots
    * The PCIe x1 slots (PCI_E1, PCI_E3) will be unavailable when installing an expansion card in the PCI_E4 slot.


    From the MSI H97 PC Mate specifications:
    Slots
    2 x PCIe x16 slots
    PCI_E2 supports PCIe 3.0
    PCI_E4 supports PCIe 2.0
    Support x16, x4/x4 modes

    2 x PCIe 2.0 x1 slots
    2 x PCI slots


    The following information is from the Intel H97 express chipset specs:

    PCI Express Configurations : x1, x2, x4
    Max # of PCI Express Lanes: 8

    This feature may not be available on all computing systems. Please check with the system vendor to determine if your system delivers this feature.
    Functionality, performance, and other benefits of this feature may vary depending on system configuration.
