Hello,

I am experiencing an issue with my NVIDIA GeForce RTX 3060 Ti where the reported VRAM in nvidia-smi is only 6 GB, while the card is supposed to have 8 GB of GDDR6 VRAM according to the specifications.

Details of my setup:

  • GPU: NVIDIA GeForce RTX 3060 Ti
  • Driver Version: 556.12
  • CUDA Version: 12.5
  • Operating System: Windows 10

Memory Report from nvidia-smi:

At the same time, Windows 10 correctly detects and displays the VRAM as 8 GB. But not nvidia-smi and not pytorch.

Hello @Gwwyn and welcome to the NVIDIA developer forums.

Can you tell me the exact brand and model of the GPU?
And can you please post the same output of nvidia-smi from your Windows 10 installation? You can tun it from the command shell just like on Linux, just append the .exe at the end.

Thanks!
