    Hello,
    I have GTX 1070 in my MSI 16L3 notebook. I have to say that this GPU is really something else compared to older 9xxM. It's powerful and it adjust it's clocks pretty well most of time. But not all the time. Let's say I have an application that I need run 60 FPS and I'd like to use as least GPU power as possible to achieve this. When I run it in with default GPU settings, GPU runs at 1800 Mhz and 4000 Mhz for Memory. I can use Afterburner to downclock Core clock to 1100Mhz and to lower memory clock by 500 Mhz. I see no difference in performance for this app. I guess I could run it on even lower clocks just fine.

    First question:
    I use Ctrl+F curve settings to set Core clock to 1100 Mhz in Afterburner. It doesn't let me set anything lower than that with UI, curve just goes back to 1100+Mhz. I can also adjust memory clock by -502Mhz at most. Is there any way or tool to downclock Core and Memory even further?

    Second question:
    Is there any special way to tell GPU to behave more power efficient? I have tried Optimal Power and Adaptive mode in Nvidia Settings without success at all.

    Thanks for response.

    Don't make the curve like that.
    I've seen checkerboard crashes when you start doing strange stuff that way, then the laptop fails to boot into windows next time.
    If you want to force a lower speed, downclock the card, then click the 0.800v voltage point on the white dot on the card and press Control L to lock the clocks. Can't lock the clocks lower than 800mv.

    I can't change clock that much directly in Afterburner with slider, neither voltage, unfortunately. I don't know why, it's grayed out. But judging how voltage/clock curve works I think this kind of curve should not be a problem. I didn't have any problems with it so far. I've got bsods only if I push undervolt too far. With 1100Mhz I think it's still overvolted.

    Only needed to press L, not CTRL + L. (strg in german)
