I'm trying to use NVAPI to get GPU information. But NvAPI fails to return the data on K20c with NVIDIA_DEVICE_NOT_FOUND
I'm using Windows Server 2012 & the display is driven by Onboard chip. Is NvApi supported on K20 cards? Please guide
Usually this is due to the wrong driver being loaded (nouveau instead of nvidia - you can check it with lsmod). Other option is to download and install up-to-date drivers from NVidia.
The command nvidia-smi should work at least and report GPU information.
