8x 1080ti with same board and celeron cpu:
i didnt setup all 8 in one shot since the cards arrived in multiple shipments. so i setup 4 at first, then 6 then 8. the only issue i ran into was that as I added more cards i had to run DDU in safe mode then reinstall nvidia drivers after all cards were plugged. then all of them would show in device manager properly. none of this "install one card, reboot, install next card, reboot" BS that other mobos go through.
risers are v07 6pins. 2 sata connections per line.
