I spent that day in a half trying to figure this out. I set the core overclock to 0 and the save reboot. Then I look at the dash and all the cores are overclocked to above 1900. I set the overclock to 25%, 50%, 75%, 100%, 125% and 150%. I even did -25% etc. and still 1900 overclock! Does nothing.  Started about 6 days ago or so. And power usage for my 1070's was 115 watts with the power limit set to 70%. Now for that last 3 days my power usage for these cards is 177 watts. I even set the power limit to 115 watts. It does nothing. Now for the last 3 days I keep getting a gpu has stopped and it restarts it if it can. I reboot works for a short time! So I change risers does nothing. I move cards, it last for maybe an hour then it does it again. I leave that pcie slot empty move the card to a different one. Does it again gpu stop's so i switch cards but not the same one as last time. And it still does it. GPU3 is driving me frekin nuts.

Sorry but I pay for a service and I expect it to at lease work.
