Vega 56 instability

[Assarad]

Greetings,

 

I got a PowerColor Red Dragon Vega 56 on sale for about 240€.

GPU-Z says I have Hynix Memory (RIP)

I instantly went into Overclocking and Undervolting the card for better performance/efficiency

https://gyazo.com/8e42058d56abd081d66cd59ca52c50bb Settings I'm crashing with but went through stresstests just fine

https://pastebin.com/e5wKqGH5 DxDiag.txt

PSU: Corsair RM650i using 2 different power cables

Both Settings went through an hour of FurMark GPU Stresstest and a tons of TimeSpy Benchmarks. Both run stable there. 

As soon as I play WoW I get "no response | wait | force close"

 

Why is WoW kinda crashing with those settings but none of the benchmarks?

Is there a database where I can compare my Vega 56 to other's?

What about stock setting? 
What is your max junction temp?
Instability on low load usually related to PSU imo. Is it possible to set fix voltage and frequency?

 

Also i don't recommend Furmark for stress testing.
