CUDA 4.0 + VS2010 +

Hello. I have VisualStudio 2010, CUDA Tools 4.0,, Windows 7 64bit and GeForce GT220.
I compiled my *.cu file: nvcc --cubin. Then I try to load mykernel.cubin: CUDA.LoadModule(“mykernel.cubit”);
LoadModule raised exception “GASS.CUDA.CUDAException”. I tryed to compile with -arch=sm_20 argument, but it is does not work too. What could be the problem?
