What cuda version to use ?

troubleshooting GPU issues on my windows WSL2 setup

The CUDA version you can use with an RTX 4070 is not solely determined by the GPU model itself but rather by the compatibility of your software environment and the drivers you have installed. However, as of my last update, the RTX 4070 should support CUDA versions that are compatible with NVIDIA’s Ampere architecture.

To find out the exact CUDA version you have installed on your system, you can use the following methods:

1. Check via Command Line:
   • On Linux, open a terminal and type:

     nvcc --version  

   • On Windows, open Command Prompt and type:

     nvcc --version  

2. Check via NVIDIA System Management Interface (nvidia-smi):
   • Open a terminal or command prompt and type:

     nvidia-smi  

   • This will display information about your GPU, including the driver version. You can then cross-reference this with NVIDIA’s documentation to determine which CUDA versions are supported by your driver.
3. Check Installed CUDA Toolkit:
   • If you have installed the CUDA Toolkit, you can check its version by navigating to the installation directory and looking for a version.txt file or similar.
4. Check in Programming Environments:
   • If you’re using a programming environment like TensorFlow or PyTorch, they often display the CUDA version being used when they initialize.

Make sure your drivers are up-to-date to ensure compatibility with the latest CUDA versions. If you’re setting up a new environment, consider installing the latest CUDA Toolkit from NVIDIA’s official website that supports your GPU and software requirements.

what do i have ?

Based on the output you provided from the nvidia-smi command, you have the following setup:

• Driver Version: 560.70
• CUDA Version: 12.6
• GPU Model: NVIDIA GeForce RTX 4070
• GPU Memory (VRAM): 8 GB (8188 MiB)
• Current GPU Temperature: 39°C
• Power Usage: 2W out of a maximum of 62W
• GPU Utilization: 0% (indicating no active processes using the GPU at the moment)

This information indicates that your system is configured with a fairly recent driver and CUDA version, which should be compatible with most modern software environments that utilize CUDA for GPU acceleration. If you’re planning to use specific software, ensure it supports CUDA 12.6 or check if there are any additional requirements or compatibility notes.
