Hi, I run 2 1080ti FTW3's and just noticed that one has a Master/Slave switch while the other has a normal/OC switch in the exact same spot. I'm assuming they do the same thing right?

    Yes.

    You may run into power issues with the Single Cables Split Between Two 8-Pin Power Connectors Split between Two Graphics Cards.

    I wondered about that but both still able to fold at max rate. Truth is I didnt have another set of cables and when I land some I probably will run a separate set but for now they seem to be just fine. The wires arent heating up or anything so the current isnt too high for the gauge wire being used.

    I ran two independent cables from power supply and I got better numbers and that’s just one 2080 FTW3.....even in benchmarks

    I don't think the cabling is as important when folding when you're looking for max efficiency not max power draw. For gaming purposes I would certainly use separate PCIe cables for each GPU.

    EVGA X99 FTWK / i7 6850K @ 4.5ghz / RTX 3080Ti FTW Ultra / 32GB Corsair LPX 3600mhz / Samsung 850Pro 256GB / Be Quiet BN516 Straight Power 12-1000w 80 Plus Platinum / Window 10 Pro

    It is Very Important when Folding to use 2 Separate PCIe Power Cables, Very Important.
    When Folding with one cable it will get warmer than using two cables so you are spreading wattage between Two Cables over One.
