So I've just set up a new rig with Windows 10 64-bit and running NVIDIA GTX 1070s. I'm getting 2.5MH/s. I am sure I have seen something like this before but I can't remember how it was resolved.
I've updated Windows, and I am running the recommended driver (I think 368.81).
Any idea how to resolve this?
EDIT: I'm reading how this could be fixed by downloading the Windows 10 Creators update. Not sure what that is but I'll try in the morning.
Did the same thing to me with my 1060s.
update your version of windows to the creators edition. 2nd option windows 7 64bit.
only chance to make it work, spent 100hr researching.
