Hi everyone,
I am experiencing an issue with MATLAB (version R2024a) on Windows 11 Pro where it fails to detect my NVIDIA T400 4GB GPU. I have already followed several troubleshooting steps without success. Here are the details of my system and the steps I've taken so far:
System Details:
  • Operating System: Windows 11 Pro Version 10.0 (Build 22631)
  • MATLAB Version: R2024a (Update 3)
  • GPU: NVIDIA T400 4GB
  • NVIDIA Driver Version: 516.94
  • CUDA Version: 11.7
Steps Taken:
  • Updated the NVIDIA drivers to the latest version (516.94).
  • Verified that the GPU is correctly recognized by the operating system using nvidia-smi:bash

  • Ran MATLAB as an administrator to ensure it has the necessary permissions.
  • Checked that the CUDA environment variables are correctly set.
  • Set the Windows power plan to "High performance".
  • Ran gpuDeviceCount in MATLAB, but it does not detect any available GPU = gpuDeviceCount; disp(['Number of GPUs available: ', num2str(n)]); % Output: Number of GPUs available: 0
Question:What can I do to resolve this issue and have MATLAB correctly detect my NVIDIA GPU? Are there any additional configuration steps I should follow or any other settings to check? Any suggestions or similar experiences would be greatly appreciated.
Thanks in advance for your help!

Hi @Andrea Molent,
Could you please execute the following command in your Command Window and attach the log:
> strace -f -o gpuDeviceCount.log matlab -nodisplay -nosplash -r "disp(gpuDeviceCount);exit"
Meanwhile you may also contact MathWorks Technical Support using the following link:

Thank you for the suggestion. It seems that the “strace ” command does not work because I am working with Windows. I followed your suggestion and forwarded the question to the Matlab Technical Support .

The 516 driver is too old for R2024a, which is on CUDA 12.2. Download the recommended 552 driver for your T400 from https://www.nvidia.com/en-gb/drivers/

Incidentally if you just type gpuDevice into MATLAB the error message should tell you your driver needs updating.
