I had a problem where the game would crash (game stop responding message).  I could Ctrl Alt Del, start task master, close it down and then restart (the computer never died).  I got tire of this and rolled back to 344.75 and it's been smooth playing since, so it seemed to be a driver issue for me.

Sounds like a blue screen, but since your driver crashed it's black. I'm not aware of a solution for bluescreen driver crashes other than NVIDEA fixing their drivers which may never happen. But this is assuming your PC crashing and needs a hard reboot to fix itself like you said.

I'm not sure why it double posted...

Oh, I thought you meant it crashes and didn't recover. In that case, uninstall and reinstall the newest driver from NVIDEA even if you already have it and install it using advanced settings. Check the option of a "clean install" and ONLY install the graphics driver (not the 3d/sound stuff). It's my understanding that this can fix the issue.

Well, I've heard that lowering the clock can fix similar issues. Its hard to say why it's not working but if you lowered the clock and it worked then you could either attempt an RMA or just be happy be the card. But the other thing you could try is using NVIDEA Expierence (part of NVIDEA control panel) to "optimize" the games performance and maybe the settings that they optimize for you would work better.

i tested Heaven on extreme 2 times. One time i left running 10 hours, without crash. Second time i left running for 8 hours , without crash too. Also i played other games, like WatchDogs, Crysis 3, Metro LL and all fine.
Only FAR Cry 4 is crashing my display driver very randomly, i will say very rarely. Screen turns to a black for a second and then app crash. Event viewer says about display crash.
One time i can play FC4 even 12 hours without crash, second time it will crash after 5 minutes. It can be game issue even if it triggers TDR?


Well, I accept that an application crashes, but NOT that it triggers a TDR. If Far Cry 4 crashes in a "normal way" (screen freeze, Windows message telling that the application has crashed), fine. But TDRs are a big no-no.

I have important question now. It can be game issue even if it triggers TDR?

I think the stock clock is too high for some cards. Despite the fact the synthetic tests are all good, that doesn't reflect real gaming and Farcry is a diffrient game from the others you mentioned. So I would say to just try to reduce the clock because that really does help a lot of people with your issue... The silicon lottery isn't always a winner, there's always losers and you must be somewhere between. Basically, silicone chips are never the same and some are better than others, there's a lot of imperfections and you must of gotten a lower end one or something.


You could try for an RMA since it's affecting your gaming and performance, either way though I would like you to try to decrease the stock and see if it helps so you can get your RMA and prove to the sales representative that there is a major issue.

First Far Cry 4 is crashing display driver very randomly. ( sometimes i can play many hours , sometimes crash after 5 minutes ).
Black screen and Application stopped . Then i saw on events: Nvlddmkm Display driver stopped responding and has recovered. I blame Far Cry 4,ok, nevermind. Many users get TDR crashes in FC4 only.
But today TDR crash happened first time in GTA V.
So what now? I have random ( very rarely ) driver crashes in FC4 and today i notice my first TDR in GTA V.
I am using newest 350.12 WHQL. Is card really unstable? Also i can run 12 hours Unigine Heaven Extreme without crash.I played Crysis 3, Watchdogs, Metro Last Light many hours without crash too.
But today second game ( GTA V ) and TDR once crash , makes me really worried. In Gta V it crashed TDR only once of 8 hours of playing. Its something bad with card?

I'm telling you that if you downclock the card and don't Expierence an issue then you have a valid claim for an RMA. So please, downclock the card to refrence speeds and if you don't have an issue then call EVGA for guidance in making an RMA request. The card should work at its factory clock and if it doesn't than you can likely get an RMA. However, you are refusing to downclock the card so there is not proof that the factory clock is at fault so you are stuck with the card.

This is my PERSONAL opinion:
 
"Stock" for me means factory clocks but also and including increasing powertarget to 110%, say in Afterburner.
For example, my GTX 970 which is in RMA right now cannot hold 1380 max boost (which is max. clock) when power target is at 110% in benches like Heaven4.0
 
Some people say that power target to 110% is not "stock", but for me is since the card is supposed to hold the 1380 which is its max speed where the card attempts to boost to. (I would have a hell of a time if I ever wanted to resell the card when I tell someone it crashes in BF4 or Heaven at PT 110% - this for sure! Power target wattage is specified in BIOS and its my belief a functioning card should not have problems with it, the default values in the BIOS are safe and way within hardware tolerance.)
 
You should always contact EVGA rep and ask them per email, explain them what's going on. Here in Europe, EVGA RMA has become very lenient and I heard that in some cases they even RMAed cards just because they won't overclock well. But of course it depends, you have to ask them. So or so, know there is no "guarantee" for whatever overclock and the only "guaranteed" number is really only the boost speed - so from a certain point of view anything above default boost speed (in my case 1316) is considered overclock.

I get yesterday only one TDR ( Timeout driver recovery ) crash in GTA V from 8 hours of playing. Or it may be caused by software? I am looking at rockstar forum and many peoples get display crashes in GTAV. Strange enough that i had only once TDR crash of 8 hours of play and that crash dont repeat Oo.
 
I tested Unigine Heaven Extreme for 12 hours, without crash. Tested Crysis 3, Metro LL, Dying Light, Watchdogs without TDR crashes.

 
I forgot to say. On past i was played on 344.75WHQL and i dont notice any TDR crash in FC4. It can be driver issue? Or maybe card fault because newest drivers 350.12 WHQL just making card harder to work and card crash? what you think?

Yeah i edited:) But i am very greatful for help and answers.
 
I am almost to decide to rma 980 . . Really i dont know what to do guys. 
First thing. Far Cry 4 is crashing randomly TDR on drivers 350.12 WHQL and 347.88 WHQL. On 344.75 WHQL is fine .
Reading internet many peoples have TDR issues even on stock clocked cards. 
Gta V crashed only once TDR yesterday , but now i am in game 12 hours and TDR dont repeat again. 
But for some reason it happened yesterday, duh. 

Other thing is that i tested Unigine Heaven Extreme for 12+ hours without crash. I played Crysis 3, WatchDogs, Metro LL, Dying Light and no crashing. So its hard to decide if really RMA my card or not. 
 

Ok i have a question.  If Far Cry 4 is stable on 344.75WHQL and not ( TDR issues ) on 350.12 WHQL rma card or not? 

I really don't think an RMA would help your situation.

This was at OCN too. For the love of God, rma the card if you think its defective. asking in 4 different forums isn't going to help if you ignore our comments. Like I said at OCN:
1. don't play fc4 if its the only game that crashes
2. use 344.75, play the game and stop obsessing
3. rma the card and be done with all of this.
 
I've seen this topic here, ocn, guru3d......
