I own a Dell Studio XPS 13 with Nvidia 9400M and 9200MGS in SLI Mode. My driver installed is 179.82(Vista 64) which has been downloaded from Dell website.
However, I am unable to use these drivers for CUDA. the nvcuda.dll has not been installed. However, for CUDA 2.0 the supported driver mentioned is found to be 178.08 or later which means my driver should be supported. However I find that nvcuda.dll is not installed in my system.
I cannot upgrade the drivers since Dell XPS 13 has not yet finished testing 185.85 drivers for CUDA 2.2 as well… When I try to install this driver after downloading from nvidia, the message appears " no supported hardware found "… So what could be the reason ?
