Nvidia Grid K2 Drivers with other Nvidia Drivers

Hi All,

I’ve recently tried to install two Grid K2 cards with other Nvidia cards (GTX 1050, 1070 and RTX 3060 Ti).

I’ve uninstalled everything with DDU, then installed “370.21_grid_win10_server2016_64bit_international.exe” ← Drivers for K2, rebooted and then installed latest WHQL drivers.

After rebooting the system recognizes all GTX and RTX cards, but K2 returns the error “This device is not working properly because Windows cannot load the required drivers for that device. (Code 31) .”

Am I missing something? Doing the installation the other way around is even worse.

Thank you.
