What is the correct version of CUDA for my nvidia driver?

Question

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 driver 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 resolve that problem? I reinstalled my Ubuntu many times.

Answer 1

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 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 older CUDA GPUs of compute capability 1.x. For those GPUs, CUDA 6.5 should work. Starting with CUDA 9.x, older CUDA GPUs of compute capability 2.x are also not supported. 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. The general support matrix is contained in the linux install guide for the specific CUDA version of interest.

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

For versions newer than 11.0, refer to the table in the release notes linked below CUDA 11.0: 450.36.06 CUDA 10.2: 440.33.01 CUDA 10.1: 418.39 CUDA 10.0: 410.48 CUDA  9.2: 396.xx CUDA  9.1: 390.xx (update) CUDA  9.0: 384.xx CUDA  8.0  375.xx (GA2) CUDA  8.0: 367.4x CUDA  7.5: 352.xx 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 CUDA  4.2: 295.41 CUDA  4.1: 285.05.33 CUDA  4.0: 270.41.19 CUDA  3.2: 260.19.26 CUDA  3.1: 256.40 CUDA  3.0: 195.36.15 

A portion of this table is maintained as Table 1 here in the release notes.
