Ryzen system ctd when under load


In advance, sorry about the English...


I've had my Ryzen 1700 for about two months now, and have had problems from day one, but can't really find anybody who's having the same issue.


My setup:

Ryzen 1700


MAI x370 gaming pro carbon

Corsair vengeance lpx ddr4 16 gb 3000 mhz (running at 2400mhz)

EVGA G3 750W

Samsung 840 pro


When ever I'm playing a game at 1080p (2560x1080) just about any settings, it will at some point crash to desktop without any errors.

At first I thought it was my RX480 card, that was broken, so after tests with another PSU it was returned and replaced with the 1070.

But it's still kind of the same. It doesn't crash as often, and before it shut down completely, but it's still doing it.


Tested with:

Witcher 3

Assassins Creeed Syndicate



Does anybody have any suggestions on how I go from here or what to test?
