greetings,
for some reason, one of our servers (an HP DL380 A11) with four L40’s has two set on mode TCC and two on mode WDDM. we need all four to be WDDM. however, when i try to do this, i get an error :
.\nvidia-smi.exe -fdm 0
Unable to set driver model for GPU 00000000:4E:00.0: Not Supported
Treating as warning and moving on.
Driver model is already set to WDDM for GPU 00000000:62:00.0.
Driver model is already set to WDDM for GPU 00000000:C9:00.0.
Unable to set driver model for GPU 00000000:DE:00.0: Not Supported
Treating as warning and moving on.
All done.
nvidia-smi shows me that all four cards are indeed L40’s, so they should all support WDDM, shouldn’t they?

does anyone know how i can set them all, or what i might check to find out why two of the cards claim it isn’t supported?
thanks.
