GTX 1080 - Is this a good overclock ?

Solution
If thats the case, you could just lower OC a bit for playing that game. Could be its more demanding than other games you play. Some games are known to be more sensitive to OCs than others.


GPU core: 2126 MHz, memory: 5454 MHz

That's the result after gpu stretch test with FurMark. Good ?
 


I even oced it higher ; GPU core: 2138 MHz, memory: 5454 MHz

It's the 8GB EVGA NVIDIA GeForce GTX1080 Founder Edition GDDR5X PCIe 3.0 Video Card.

What's the reason it's 100% stable and Mafia 3 freezes after a while on this overclock ?
 


No it does not freeze if i lower my OC a bit.
