Quick update: tried reinstalling all the drivers, still no luck though. Max 8 cards of the same spec. Btw I'm running W10 Home edition, maybe it works on W10 Pro?
This is the setup where i use 10 cards;
7x 1070
2x 1060 3gb
1x 1060 6gb.
If i add another 1070 card, that card will not install in windows, same thing if i remove the three 1060 cards, the last 1070 card still wont install on windows(Works fine in another computer). Maybe there is a limit for the same type of cards? I dont know. Before latest windows update, i was only able to use 8 Cards of NVIDIA no mather what mixups where used.
I use W10 Pro. 8GB of memory and G3950 CPU and Asrock Pro BTC+
