Does I must use only a version 6.0 of CUDA for use free evaluation version of cuBLAS-XT Premier for

I want to use cuBLAS XT Premier for multi-GPU usage (1 - 4 x GPU). I downloaded free evaluation version of cuBLAS-XT Premier: https://developer.nvidia.com/rdp/assets/cublas-xt-download

But in readme.txt wrote that I must download CUDA 6.0:

2) Set up the CUDA toolkit:
    - Download and install the CUDA 6.0 toolkit.

Does it mean that I necessarily have to use only a version 6.0 of CUDA, but no 6.5/7.0/7.5?

When I made all what written in readme.txt with CUDA 7.0 and launch MAGMA 1.7.0 dgemm or other test then I get an error: Segmentation fault.

I am also interested to know how to use cuBLAS XT Premier after upgrading to CUDA 7.5.

Should I also keep CUDA 6.0 and compile against it for cuBLAS XT Premier?
