    Pcie lane usage with dual gpu and x4 nvme drives


    I am trying to figure out if I will be able to run 2 2080 ti in sli in x16/x16 config with 3 nvme drives (each at x4) , I would like to add a 4th nvme drive sometime in the future if possible

    My setup is a somewhat new build :

    Asus rampage omega
    rog strix oc 2080 ti ( currently only have one)
    m.2_1: wd black 500gb (os drive)
    m.2_2: hp ex950 2tb
    Dimm slot: intel 660p 2tb ( on the way )

    I would like to confirm that with the setup above I can run 2080 ti in sli x16/x16 before investing in a second gpu because I will have 3 m.2 nvme drives. If I can i will pick up a 4th drive as well. I know as long as I do not occupy the 3rd pcie slot on the mobo that the gpu's can both run at x16. I am unclear on how occupying 3 or 4 nvme slots on the board will affect how the lanes are distributed to gpu's in sli ( pcie slot 1 & 2).

    You have 44 lanes on the CPU & 24 lanes on the chipset with your set up, so go nuts, enjoy.
