AMD Crossfire Hard Lock

[xocox]

I recently built a new system and it locks up after about 15 or 20 minutes in games with crossfire enabled. I thought it might have been a driver issue, so I reinstalled the latest amd drivers (crimson 17.1.2 at the time of writing), but the problem persists. Any help would be greatly appreciated

 

PC Specs.

Asrock z270m Pro4

Intel 7600k

16gb G.skill DDR4

2x XFX GTR RX 480 BE

Evga 850GQ PSU

1x Seagate Barracuda 1TB HDD

 

EDIT: It also seems to be doing it with a single card as well.

 

EDIT 2: Replaced with an r9 390 and it is running fine. Probably going to RMA

Does it do it with only one of the cards? Do both cards work individually?

Yes it does.
