Hello, out there,

I´m running the following System:


Intel I7 4820 K

Sapp. R9 290X Vapor-X 8Gb

Sapp. R9 290 Tri-X OC 4Gb

Sapp. R9 290 VaporX 4Gb

Win 10

Catalyst 15.9.1 Beta


With Win 8.1 this mixed Crossfire setup, even with three different Bios´ was possible, since the upgrade, with Win 10, after enabling crossfire, and starting any game, this bluescreen shows up an my PC hits full brake.

Can anybody explain to me , what the problem is? Is there a way to fix it?
