Hi again,
After the first crash (after 15ns simulation time) I can't make more than 1ns.... Probably the best what I can do is to change the Bios to the non SC version and if I have the same problems on reference cloks

Hi Ross and all,
The problems with my GTX 780Ti SC continued and are real disaster. I tried on a new system and it crash very often (every 1 000 000 steps, if I am lucky I can get 10-15ns). ntf=1 seems to improve the situation but it is not a general solution. No problems with the GTX Titan on the same system. Should I test the card on some other PC? Should I downclock the GPU? Is it possible this to be Amber/Nvidia driver related problem? I was wondering should I have to and whether is possible to ask EVGA for RMA? They can say just ..this is a gaming card :( Anyone with similar problems and GTX 780Ti?
Regards,
Filip
