However, I can get around 470 sols from the card connected to the monitor via DVI. When I disconnect the monitor and look at the screen from the TightVNC viewer(wich is basically like teamviewer), the sol/s tank to like 300...
Is there anyway I can stop this?
there is something causeing it, honestly I don't experience this on my 6x gpu 1070 rig and it never has a monitor connected
but its also got nothing on the os but the drivers for the gpu and the mining software, something like your tightVNC viewer may be causing an issue, id bet programs like tightvnc use part of the gpu when creating the screen so you can see the desktop, which when apon disconnection of the physical monitor you see a sol tank to something a little low cause the tightvnc screen becomes active
