I have 1080 ftw and I have this problem too. In 3dmark's skydiver benchmark, my card gives the black out problem everytime at exact point that when woman fires a flare in the cave. But, it doesn't happen unless it is in debug mode. So, I think the issue is cards boost profile related. It might be hardware issue that some cards are not able to go beyond base clock or something. Since it is ftw and advertised as with its boost clock, they have to exchange failed cards with new ones instead of bios update which would change boost clock lower than advertised number. Just a guess. :)
I bought my card directly from Amazon on August 28th. Instead of Rma process, I am going to try Amazon return program.

You might be better off with the RMA. If you do the return and buy another or they exchange it, you might end up with an old card.

I tried ATS + K200 again, on the old cards. It works fine now, so I guess it was an (un)lucky combo of the cards and 'something' in ATS (it was a beta version when I encountered it, now it's a release version). So I can't use that anymore as a quick test.
 
Old cards still randomly crash in WoW, so definitively defective. Will swap them out later today, after some more testing with the old ones to see if I can't find something that gives me a quick result .

Well, guess what. Black screen and fans spin up to 100%. No overclock, no nothing. 
 
I received my 1080 ftw yesterday, and this thing happened some moments ago, when I was playing Dragon Age: Inquisition.
 
I bought the card directly from eu.evga.com and I made the purchase on the 2nd of September and it was shipped on the 8th of September. Obviously I will RMA it, but I hate if I have to pay the shipping cost. I already paid too much for a frustrating issue. I hope someone from the evga team wil explain better how the process goes exactly, because it asks a lot of information, just for one support ticket.
 
I don' t know if this is relative, but my serial number is 16125xxxxxxxxxxx.
 
I' ll try this debug fix, but I didn't pay premium for that. First evga graphics card and I' m starting to regret it. I hope at least, that the support is as good as I hear.

 
And it just happened again. Just idling in desktop. I didn't even have the time to enable the debug mode.

*Quick update to hopefully quell some fears with the replacement RMA cards being sent out, 7 days + now with no black screens.
 
Fingers crossed that the RMA's being sent out from about a week ago seem to be performing as expected, I will post again if I experience any further issues.
 
FYI games and benches used:
 
Arkham Knight
Bioshock remaster
Outlast
Metro Last Light redux
Alien Isolation
Overwatch
 
3dmark - Firestrike and Time spy
 
When using the benchmarks I overclocked the card by 120mhz, it throttles down to a stable 2088mhz at around 66c. Otherwise the games I'm playing are at the cards factory overclocked settings.

I tried this. Indeed, after the flare black screen etc...
 
I'm not in debug mode. And I'm running standard clocks. The moment it happened 1st card was @ 1506Mhz.
 
 
EDIT: Ugh, after a reboot it runs fine. I'm getting fed up with this guessing and testing, I want an official statement with technical details and an explanation of what they did to resolve it

So I got the problem again after a week of not seeing it, also while playing Witcher 3.
 
Problem is, this time the card simply dropped dead. After resetting, there's only a single white bar on my main monitor. Plugged  in my old 770 and it works normally. No choice but to RMA this time.
 

 

 
How long is everyone's 1080 FTW Hybrid RMA taking for their replacement card to ship out? My RMA ticket was entered 09/08/2016, almost 10 days ago, and still has not shipped. I guess they are waiting for more stock, but would be nice to know since it says to allow 2-3 to ship from when the ticket was entered. The NVidia debug mode seems to be working in the meantime so no rush, just wondered what was happening. I've put a ticket in requesting the same btw, just wondering if this wait time is normal for everyone.
 
(note: this is for the 1080 HYBRID, not the non-hybrid FTW cards)
 
 
 

So far my first RMA is working perfectly, and I have been able to play Elite Dangerous on the VIVE for 4 hours without a single problem. Card sticks mostly around 2020Mhz which is pretty much what I was getting before.
 
So far so good, it looks to be fixed.

I received my RMA yesterday from EVGA. So far, it has not had a problem at all. I have put in a good 6 hours of different games that would cause the issue within the first 1 hour of play. Sometimes, within 5 minutes. I am glad they did an advance RMA to save me the trouble of having to wait even longer! I will update this if I for some reason run into it again, but I believe this card does not have it or else I would have gotten it by now.
