Here’s my working setup again:
- Flashing Bios and Installing the latest release
- Installing Windows 10 Pro on a UEFI/ GPT partition (here’s nothing to do - it works out of the box)
- doing all Windows updates
- Connecting only one card with a USB-Riser and installing the drivers - you have to be patient with WIN 10. It can take several minutes. Open the device manager and take a look at the Graphic section. Only if NVIDIA GeForce GTX 1070 is shown there, driver installation is finished. Wait this time.
- Changing in the BIOS ‘PEG0’ and ‘PEG1’ values to ‘Gen1’ and Set ‘Above 4G Decoding’ to ‘Enabled’
- Restarting and check if everything works fine.
- After this I connect the next three cards, Open the device manager and take a look at the Graphic section and waiting until NVIDIA GeForce GTX 1070 is shown for all four cards.
- Connecting the last two cards - restarting and it’s done
