Just got a call and have to run...
Will wait to see your results Sajin...

Tested for half hour as thats all I could get afterburner to show. Didn't have any drops with the original 970, haven't gotten the new one yet.
Driver 347.09 btw  

331.82 Single GPU = No drops.
331.82 SLI = No drops.
347.09 Single GPU = No drops.
347.09 SLI = Drops to 0%.

interesting
so, its mainly an sli bug
im out of testing then, lol

Not sure if it's just a SLI bug or not. ubbb69 in this thread says his card does the same thing, sounds like he only has one card.

I only have one card but my problem is a little different. Instead of dropping % of usage it is throttling down to 900mhz or thereabouts in heavy use. Main reason i was thinking vrm problem. I have been testing it all night and at first thought it was the same problem. I think that my card can not supply enough voltage for the chip.

Do you have power management mode inside the nvidia control panel set to prefer maximum performance? If not, change it to that and then reboot the pc and retest.

My system crashes to black screen when changing certain scenes in Heaven... I think I might apply for an RMA.
 
I believe its not a PSU problem, I have a brand new Supernova 750B and have tried every different power plug configuration.

My Rigs will do the same in Heaven if I overclock my CPU and GPU to high.

I get the same thing with my GTX 980 SC. I ran Unigine Haven 4.0 didn't run for an hour but I ran the benchmark and my GPU usage would drop from 99%-50% on some opening scenes for a second or too, then back up to 99%. This doesn't just happen in Unigine Heaven it happens in games as well but a lot worse. In all the games I play I get about 30%-70% GPU usage never really hits 99%. I rolled out my CPU do to it not hitting 100% load.

Have you test this?
"I fixed a "Display driver stopped responding and has recovered" issue by settings PhysX to CPU in nvidia control panel. Maybe it will work for you..." Link
That is Set PhysX to CPU and then test for Drop Out?

@bcavnaugh
Setting the physx to CPU doesn't help.
 
@j2345912
Good to see not everyone is affected.

sajin are you running any custom bios or mods on your titans?

Hey guys here is something for experienced users, I am a little skeptical to do it but some of the customers think its a TDP issue and voltage. Some people are calming to get a more stable card by under clocking. I would post the links but I just signed into EVGA and can't yet.
 
Personally I think its Nvidia and the Drivers, I can not get over 30-55 Percent GPU load and same with Power its always like 40-50. I put my old 650 Ti Boost in using the new Drivers same thing, rolled back to a previous driver non 900 series and it worked as expected and better than my GTX 970 so depressing.
 
Its on overclock.net called Disable Boost and "Bake-In" Max Game Stable Clocks for Maxwell II
 
Good luck

just had this running for little over an hour on 347.09 drivers and SLI 980 cards with zero drops in usage %
 
BUT i have been having a strange issue in any game or video in a browser where every so often it hitches/stutters for a split second with no usage % drops and no sound stuttering just fps dips super low for half a second then returns to normal
 
my laptop running a 850m however DOES have these usage % drops every 20~ minutes or so

Very strange. How can you not be getting dips in usage % when you're getting super low dips in fps for half a second. Try setting your hardware polling interval to 200 milliseconds inside afterburner/precision then rerun the test to see if you can pickup the drops. Precision/Afterburner are setup for 1 second update intervals, setting it to 200 milliseconds will make the graph update faster then half a second every second.

I agree that this performance drop was a pain in the butt! Bf4 and other games were just awful. After some time I fixed the issue with my FTW. I'm not going to say how as EVGA would not be happy with the way I did it, but I can say the reason it was flawed was because of the poor board and parts. I currently can run the card at 1478 core with a 1745 boost. Of course this is nothing compared to my Gigabyte G1 out of the box with no fixes needed. A family member just got a MSI gamer and is having very good results with it much like the G!.

EVGA won't care. EVGA wants to see your feedback so they can improve things. What did you do?

Your do a very good job in helping the community. I have had this fix running now for 2 weeks and if all goes well in another 2 weeks (still testing) I will post my fix.
 
As far as EVGA wanting feedback, the net is full of people who have asked EVGA to address the issues with some of these cards. There reply is simple "buy our new product ".

Thanks. I'll be looking forward to your reply in two weeks.
