**Execute the following registry hack so the GPU is recognized by software (Task manager, Plex)**

Original Post on github (for Tesla P40): JingShing/How-to-use-tesla-p40: A manual for helping using tesla p40 gpu (github.com)

After installing the driver, you may notice that the Tesla P4 graphics card is not detected in the Task Manager. Therefore, you need to modify the registry.

Please press WIN + R
to open the Run window, then enter regedit
to get into register table, and then enter HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Class\{4d36e968-e325-11ce-bfc1-08002be10318}\0001
in path to modify its content.

Modify AdapterType to 1

Modify FeatureScore to d1

Add Dword:

Fill in 1 for EnableMsHybrid

Fill in 7 for GridLicensedFeatures

After modifying the registry, you can choose to restart or disable and enable P40 in the device manager to see that P40 has been successfully called in the Task Manager.
