What is version of cuda for nvidia 304.125

Question:

Tag: ubuntu,cuda,ubuntu-14.04,nvidia

I am using ubuntu 14.04. I want to install CUDA. But I don't know which version is good for my laptop. I trace my drive that is

$cat /proc/driver/nvidia/version

NVRM version: NVIDIA UNIX x86_64 Kernel Module  304.125  Mon Dec  1 19:58:28 PST 2014
GCC version:  gcc version 4.8.2 (Ubuntu 4.8.2-19ubuntu1) 

I tried to install CUDA cuda-linux64-rel-7.0.28-19326674 but when I test by command

./deviceQuery
./deviceQuery Starting...

 CUDA Device Query (Runtime API) version (CUDART static linking)

cudaGetDeviceCount returned 35
-> CUDA driver version is insufficient for CUDA runtime version
Result = FAIL

Could you help me reslove that problem? I reinstall my ubuntu many time. Thank you so much


Answer:

304.xx is a driver that will support CUDA 5 and previous (does not support newer CUDA versions.)

If you want to reinstall ubuntu to create a clean setup, the linux getting started guide has all the instructions needed to set up CUDA 7 if that is your intent.

I believe you are picking up a 304.xx driver via a specific (ie. separate) driver install. This is not necessary if you want to use CUDA 7, you can just use the runfile installer method which has all the necessary components including an appropriate driver (346.46). Note that CUDA 7 will not be usable with certain older CUDA GPUs. For those GPUs, CUDA 6.5 should work. Older CUDA toolkits are available for download here. Note that any given CUDA toolkit has specific Linux distros (including version number) that are supported. Not all distros are supported on every CUDA toolkit version.

For reference, on linux, the previous CUDA toolkits required the following minimum driver versions:

CUDA 7.0: 346.xx
CUDA 6.5: 340.xx
CUDA 6.0: 331.xx
CUDA 5.5: 319.xx
CUDA 5.0: 304.xx
