Trouble getting CUDA to work on Dell XPS 15 laptop


I have recently acquired a Dell XPS 15 laptop with an Intel Core i7 740QM cpu, an nVidia GT435M graphics card, and 6 GB DDR3 RAM. After installing the Cuda toolkit and Cuda SDK, when I try to execute bandwidthtest, I get the following error in Windows 7 (64 bit):


bandwidthTest.exe starting...

Running on...

Quick Mode


/ : cudaSafeCall() Runtime API error : CUDA driver version

is insufficient for CUDA runtime version.

I understand that I require a CUDA capable driver from nVidia, but when I try to download one from the nVidia site, I am asked to download drivers from Dell rather than nVidia.

Any ideas?

Thanks in advance.

EDIT: I have tried to install both




as drivers. But I get the message “This graphics driver could not find compatible graphics hardware.”


The correct driver to download is


NOT (at least at this time) the ones on the NVIDIA “Get CUDA” webpage.
