I have crossfired a 290x with a 390x and the setup works great... except when i try to alt tab from a game.
Sometimes it works (less that 20%) most times it causes the AMD drivers to crash (and it throws an error) and the computer completely freezes and cause me to do a hard reset. I've tried changing the paging file and i've tried makind the windows timeout go longer. It just appears to crash the game when i alt tab and this doesn't happen with a single card. Any help would be great.
I'm using an XFX 8gb 390x with a 4gb tri-oc 290x fyi.
Windows 10 Pro 64-bit
