I have cards 280X they give 15 Sol. And I Have 380X cards - they give only 9.5 Sol. Anyone know wy?
That's strange, are you a Linux user? and using zcashclientgpu_silentarmy ?
I mine on Windows 8.1 and use zcashclientgpu_silentarmy in both systems. And I have 390 cards they give 17 Sol each. I wonder why 380X gives only 9.5
