    Reports are coming in of voltage issues with 2 cards in SLI ...

    Read here: https://forums.geforce.com/default/...way-lower-voltage-than-the-other-driver-bug-/

    Just popped in my MSI Gaming GTX 970 cards and for some reason (others on various forums are confirming) when running in SLI the secondary card always runs at around 1.19v maximum for the vGPU while in my case the main card is running at 1.243v as expected. This is limiting overclock potential a great deal. @ManuelG or someone, I assume this is a driver issue? If so any status on when this will be fixed? Both cards have been tested individually and go to 1.243v but if I run them in SLI the secondary card always stays at 1.19v :(.

    Anyone else notice anything?

    I haven't tried with my Gigabyte GTX 970s in SLI.
    I haven't needed to increase the voltage to achieve of 1500mhz.

    This isn't just with the new cards. I had the same issues with 680 SLI, 780 SLI and 770 SLI. I've posted about it before. I would always wonder why each card would run at different voltages when in sli but would run normally when in single card use.
