Hi!

I have a problem with my graphic card (GTX 560 made by gainward). I'm working with Windows Seven 64 pack 1 installed and C++ updated. The GPU pilot is 301.42. Even though, the GPU computing of blender 2.63 doesn't work, however it was fine with the 2.62 version.

A professionnal that I know, has the same configuration than mine, and it works just fine for him. He told me that I may have a faked 560 (faked cheap), is it possible? And how can I know that?

His card isn't from the same manufacturer, could it be the reason?

I've tried other builts, same results.

Could you help me please?

I fake card is a possibility, but I would suspect driver problems first. Are you using the nVidia driver?

yes
