TESLA GPU WDDM vs MCDM mode

[desbiensl]

I have in my system a RTX 2060 graphic card and TESLA P100 for scientific calculation.

I use your very well designed software, to control the speed of an external fan to cool down the TESLA card.

I wanted to upgraded the nvidia drivers (from 551.61 to 560.94) and in order to make it work I had to switch the card from WDDM mode to MCDM mode.

nvidia-smi can read the GPU temperature in both modes but not FanControl, there is no temperature sensor associated with the TESLA card when it it in MCDM mode.

Otherwise, great software, thank you !

Are you using NvAPIWrapper or the LHM GPU source?

In WDDM mode, both methods are valid for the capture of the GPU temperature, I use the NvAPIWrapper source.

In MCDM mode, there was no temperature source available for the TESLA card.
