    Default SLI not showing in Nvidia Control Panel

    I'm running a Asrock Z170 Extreme 7+ with an Intel Skylake i7 6700 processor and 16 Megs of Corsair Vengence 2666Mhz DDR4. I have a Thermatake P5 case and my 2 EVGA GTX 970's mounted vertical. I just pulled these cards from my Asrock Z97 Mobo and the SLI worked great in a surround with 3x 27" monitors at 5750 x 1080 in Ultra. I am using the same SLI bridge so I know the bridge works. The issue is the SLI is not showing up in the "Nvidia Control Panel". I have downloaded and installed the latest drivers 361.43. Both cards are showing up in the device manager. And the bios is up to date. But still no SLI.

    It will allow me to plug all 3 monitors into a single card to get the surround at 5760 x 1080 however SLI is still not showing. And when I tried 3D Mark it said 2 cards no SLI.

    Now here is where it might be an issue. The mobo contains 4 PCIe 16x slots. And due to the cable lengths I am using the 9.8" card cable supplied by Thermaltake is in the first 16x slot which in the manual is the PCIe (2) slot and the second card cable (much shorter) is in the PCIe (6) slot at the bottom. SLI options are not there. I did order an additional PCIe 16" cable that is 9" long. But I did not think it mattered what PCIe slot you plugged into, or where the bridge plugged in front or back.

    Could it be that I'm using 2 PCIe busses that are not directly next to each other?

    Welcome to the forum.

    From your motherboard user manual:

    2.4 Expansion Slots (PCI Express Slots)

    • PCIE1 (PCIe 2.0 x1 slot) is used for PCI Express x1 lane width cards.
    • PCIE2 (PCIe 3.0 x16 slot) is used for PCI Express x16 lane width graphics cards.
    • PCIE3 (PCIe 3.0 x16 slot) is used for PCI Express x4 lane width graphics cards.
    • PCIE4 (PCIe 3.0 x16 slot) is used for PCI Express x8 lane width graphics cards.
    • PCIE5 (PCIe 3.0 x1 slot) is used for PCI Express x1 lane width cards.
    • PCIE6 (PCIe 3.0 x16 slot) is used for PCI Express x4 lane width graphics cards.

    In order for SLI to work, each PCI-e slot must have x8 or higher lane width and this is why SLI can not be enabled.

    The PCIE6 slot only has x4 lane width.

    U da Man, profJim

    Roger that, thanks for the Help... I knew there was someone smarter than me out there. Kind of embarrassed I over looked that. Now I need to wait patiently for the new expansion ribbons.

    You're welcome, glad to help out.

    Let us know how it works when your new pci-e riser ribbons arrive.
