Ok so I have 2 x gtx 970s and 2 x gtx 1060s. Windows 10 how can I possibly run all four at the same time? They use two different video drivers?
I'm a newb but to my knowledge you can't. I started with a 970 and got it hashing 19 MH/s but was unable to use it and the 1070s I started buying. I only have 10xx series cards in my windows machine now. My Linux rig runs 1070s, 1060s and 1 970s all without any trouble however I cannot figure out how to overclock the 970 in Linux so its running around 18.5 MH/s. But at least its running and I can control the fan speed. The 10xx series cards all overclock via server-x settings without any problem
What are you using to overclock 10xx cards in Linux and what hash rate are you getting with that? Are you putting things in xorg.conf that you can share or are you changing in the GUI nvidia-settings? I changed in the GUI, but it didn't have any effect. Or are you executing on the command line?
