I've got a clean install of Windows 10 Pro and it will not see my second 295X2. I have tried driver 15.7.1 and the 15.11 beta driver and both GPU-Z and even device manager do not show my second card. Everything worked just fine with 8.1. If tried everything uninstalled with DDU, pulled the cards out, and crossfire box is checked.
Any ideas as I'm out of options to try.
