Installing Tesla k40m and Quadro M4000

I have HP z440 running Win10. In specs, it said nVidia Telsa K40 is compatible. I have it installed. I also have an nVidia Quadro M4000 installed with latest drivers I downloaded for both devices.

The system detected both devices, but it only recognize the M4000. Windows Device Manager sees both devices, but it seems that the driver isn’t recognized for the k40.

Any suggestions how I might be able to get both of these devices working in my computer.

My driver version is 537.70. Do I have to rollback to an earlier version? If so, which version? Thanks.

PS. I downloaded the drivers data center tesla desktop v463.15 and it didn’t work either.
