Unigine Heaven 4.0 crashing with nvwgf2um.dll

[litwicki24]

My new card, and heaven is crashing for about in 10-15 minutes with nvwgf2um.dll.
Just the driver is crashing on my MSI 770 Lightning while trying to run Unigine Heaven.


I am using 327.23 WHQL.

I am trying also with
320.49 WHQL , 331 WHQL and the same problem
Why my card is crashing only in Heaven after 15-20 minutes with: ""Display driver stopped responding and has recovered""

770 got problems with that tests? Its my fourth card 770 Lightning and i get the same problem. I doubt that 4 cards are not stable from a row?!!
Its my fourth Lightning 770 and the same crashing on Heaven 4.0. Why that cards are not fully stable before going out from factory?
Or something wrong with that configuration to Heaven 4.0?



Can someone check test Heaven 4.0 with their Lightning 770? I will be more patient.


Other games are stable and other benchmarks ( 3dmark 13, 11 )

Are you running with the GPU overclocked, if so try running @stock settings.

Heaven 4 is also very hard on graphics cards so watch your temps.

I don't know what settings the guy in the video is using but give the settings in the link below a try so we can see how your card is performing.

I am using stock settings card , OC by factory.

I even cant pass loop in heaven because of crash.


All other benchmarks , like 3dmark 11 or 13 passes fine a lot of hours.
Even games are stable. I can play Battlefield 4 for few hours without single crash.



Why my 5x 770 Lightning cant get pass that test on extreme tesselation?!

Have you tried underclocking the card. This will not fix your problem but will point to a faulty card.

Do you have good case ventilation, and what sort of temps are you getting on your card.
