So I recently purchased a Gigabyte Waterforce 980 Ti. I overclocked it to 1600 MHz core and 8000 MHz memory, with a custom BIOS hitting just under 1.3v.
Every single game I play is stable. I've played nine hours or so of Star Wars Battlefront, the entire campaign of Crysis 3, five hours of Rocket League, and survived countless runs of Unigine Heaven and 3DMark Firestrike. The only thing that crashes my GPU is Ashes. I can make it anywhere from one to five minutes into a game before it gives up.
I know the answer to the crashing is to just lower or disable the overclock. I'm not looking for a solution to the crashing. I'm just curious what about this game causes the problem when every single other application doesn't.
The troubleshooting page says this game, being DX12, pushes the hardware more. I'm getting crashes in the DX11 and DX12 versions. I have a liquid cooled GPU with an aggressive fan curve, keeping it under 60c at all times. That is excluding the back of the card, since it is just an AIO cooler that happens to run copper heat pipes over the VRMs on the front.
I have also played Star Citizen, another DX12 title, with no crashing. The only weird thing I've noticed from Ashes is that the %TDP sensor runs a little high. I occasionally saw power perfcaps, which seems odd considering the BIOS I'm running and the fact that my card has dual 8-pin power inputs.
