I have a system with multiple 470s, they are stuck at idle clocks. In Wattman, sliders are at 0, and all the clocks/voltage things are N/A. Reset in Wattman does nothing. I had had this problem on one of them before, and could eventually get it to work after driver reinstall, sometimes needed on uninstall with DDU. Now both are stuck, reinstalled 16.7.3 and 16.8.2 drivers 5 times still stuck. 300/300 clocks is kind of useless, terrible framerates. I am on Win10.
