295x2 has been fine. Since the Crimson updates for RX480 my system will randomly turn of during a game.
Have a 1000 watt recommended Corsair PSU. Under a year old.
Asrock x99m Killer mobo
I have custom watercooling and have not had temps above 60 deg on crash, so not a heat issue.
Pretty sure it is some power issue. There are no artifacts or symptoms leading up to a crash, it just turns straight of and restarts.
I have increased power 50% in Crimson on game profiles for if it wasn't getting enough power. Still drops out.
In the prosses of rolling back to a Feb 2016 driver to see if that fixes my issues.
