bandwidthtest failed.

Accelerated Computing CUDA CUDA Programming and Performance

Hi everyone,

When I execute the bandwidthtest, it shows the following error:

"C:\ProgramData\NVIDIA Corporation\NVIDIA GPU Computing SDK 4.0\C\bin\win64\Release\bandwidthTest.exe Starting…

Running on…

cudaGetDeviceProperties returned 3
→ initialization error
"

I am new to CUDA and have no idea in solving this problem.

My system is :
2-way SLI GTX570
Driver 270.61
CUDA toolkit 4.0.13

The nvcc can be executed (though I have not really compile anything CUDA)

Please help in solving this!

Oh I forgot to mention, my OS is windows 7 64bit

You should run deviceQuery first to see if your system is configured properly for CUDA!
