    Default New Mobo GAZ87X-OC Force and SLI doubt

    HI guys how are you?

    I have a doubt and need some help

    i just bought a MB GA-Z87X-OC Force, it`s working nice

    But when i enable my 2 way SLI in something weird happen

    when i concet the cable, in my cade a DP one because i use 1440p here in the top card it shows that the monitor is connectd in the VGA number 2 and not the number 1, and when i connect the cable in the botton card it shows that is the VGA one, it is wrong right? Or normal in some cases?

    Take a look, this example is when i have the cable and SLI enabled in the botton card



    Should this config be correct in the top card instead the botton one?

    Thanks

    Yes, it is set to PCI-E 1, the cards are connected in the slots 1 and 3 to make a 16/16 SLI strange, i think something might be wrong or not?

    Any more idea why it is happening? The cards are plugged in the first slot and slot 3 as the manual asks to to make 16/16, i just confirmed in the GPUZ that i`m using 16/16 here, but just in Nvidia control panel it says that if i connect the video cable in the card that is in the first slot i`m using the card 2 instead the card 1

    Thanks

    From my SLI experience, the settings in the Nvidia control panel are correct.
    PhysX is assigned to the second video card and your monitor cable is connected to the first (top) video card.
    The PhysX Auto-select setting defaults to the 2nd video card with a setup like you have.

    A web search using nvidia control panel guide provides links that provide more information.

    But the image i`ve posted in the first post in when the cable is in the bottom card and not the top one, when i connect the cable at the bottom one is when the image at the first post looks like

    From page 10 in the motherboard manual:
    Expansion Slots 3 x PCI Express x16 slots, running at x16 (PCIEX16_1~3)
    • For optimum performance, if only one expansion card is to be installed, be sure to install it in the PCIEX16_2 slot.
    • 2 x PCI Express x16 slots, running at x8 (PCIEX8_1~2)
      • The PCIEX8_1 slot shares bandwidth with the PCIEX16_1 slot and the PCIEX8_2 slot with PCIEX16_3.
        The PCIEX16_1/PCIEX16_3 slot will operate at up to x8 mode when the PCIEX8_1/PCIEX8_2 is populated.

      (The PCIEX16 and PCIEX8 slots conform to PCI Express 3.0 standard.)
      • The PCIEX16_2 slot will become unavailable when an expansion card is installed in the orange PCI Express x16 slot.

    • 2xPCI Express x1 slots
    (The PCI Express x1 slots conform to PCI Express 2.0 standard.)

    You are using the pciex16_1 and pciex16_3 slots.
    I'm surprised that GPU-z shows both cards configured with x16 bandwidth, even with the PEX8747 switch.

    Page 8 in your shows that a PEX8747 switch is used with most pci-e x16/x8 slots.
    I don't know if this has something to do with the Nvidia Control Panel SLI display diagram.

    From page 28 in your motherboard user manual:
    3) OC_PEG (PCIe Power Connector)
    The power connector provide auxiliary power to the onboard PCI Express x16 slots. When two or more graphics cards are installed, we recommend that you connect the SATA power cable from the power supply to the OC_PEG connector to ensure system stability.
    Have you connected a sata power cable to this connector?
