GPU doesn`t work / crashes

[lichtmaschine]

Hi there,

since a few weeks, Vray GPU crashes at 95% of my scenes. When I´m merging everything in a new scene, GPU works for one hour or two, then crashing again. Any suggestions ? Software used : Windows 7 x64, Max 2012, Vray 2.10.01 Nvidia GTX 480 266.58 driver.

Best regards
Ingo
