MATLAB: Can’t I run gpuDevice in MATLAB

gpuParallel Computing Toolbox

I am trying to use gpuArray function for my MATLAB code. I am getting the following error when trying to run gpuDevice,
Error using gpuDevice (line 26)
An unexpected error occurred during CUDA execution. The CUDA error was:
CUDA driver version is insufficient for CUDA runtime Version
Running parallel.gpu.GPUDevice.getDevice(1) gives this,
ans = 
CUDADevice with properties:
                      Name: 'Quadro M3000M'
                     Index: 1

and
>> parallel.internal.gpu.CUDADriverVersion
ans =
      '6.14.13.6213 (362.13)'
Other Details,
  • MATLAB Version = 2017a with parallel computing Toolbox
  • Platform = Windows 7
MATLAB 2017a has CUDA toolkit Version 8.0. The Driver Version also seems to be 8. Then why is there an erorr? or am I wrong about the Driver Version?
Please help me with this!

The error is resolved now. I updated the NVIDIA Driver to 391.33 and it worked. Updated details are as below,
