I'm running 2x Fury X (One XFX one Sapphire) with an i7 4790k (nothing overclocked at the moment) on a MSI KRAIT Z97s mobo in Windows 10 64-bit. I've updated all drivers, including the mobo, and I'm stuck. Almost every game I play experiences a complete lockup with black screen (audio keeps playing) and requires a reboot (usually). I can play without lockup when using a single card. Not sure where else to go so any help/suggestions are appreciated.
Edit: This happens when running at 4k whether or not freesync is enabled. I can't take a screenshot as the whole system locks (blackscreen) and sound starts stuttering.
