Did you use CUDA or OpenCL? Does it happen on any scene or just a particular scene?

I use CUDA. Any scene.

Please use the official 2.63a release to test from blender.org or a recent version from the buildbot: http://builder.blender.org/download/
Never report a bug, only confirmed on such a heavily patched graphicall build. :)

Ah my bad, the official ones do not provide CUDA 3.0 kernels. Will make a new one.

Luc: Please try this build: http://blender.dingto.org/builds/trunk_win64_47070.7z
It's the current SVN for windows x64, built with Toolkit 4.2.

Thank for your help. I tried your build with gpu x2. Now, Blender works with a basic scene (simple cube). But Blender don't work (crash at the end of rendering) with this scene > http://dl.dropbox.com/u/28186945/BatM19_GrosPlan.blend

Ok, thanks,
there have been some fixes in Cycles for the Toolkit 4.2, please check once more a current build: http://builder.blender.org/download/ Download the "Windows 64 bit" one.

Ok, I have to mark this as ToDo now, none of the Cycles developers has a 6xx card, we can't test nor reproduce the issue.

Hi,

I'm sorry, my company can't send you a graphic card.

From version r49110, I can run both gpu with a astuce (this technique is unstable on some computers, crash after multiple images rendering).
- I run the rendu in the 3d view (with one gpu)
- I choose "GeForce GTX 690 (2x)" in user perferences
- I choose "Keep UI" in display render
- I add a window "UV/Image Editor
- I run the animation rendering

This method is very unstable, also works on version r50034.

I hope you find a solution.
