I have two H81 Pro BTC R2.0 MB's based mining systems. One with 6 Nvidia 1070's and a 4790K CPU and one with 5 Nvidia 1660 TI's and a G3258 CPU. Both systems seem to work as advertised. I have searched the Web but cannot find anything that says how many Nvidia cards these MB's will support.

The reason I even asked the question is I also have a H110 Pro BTC+ MB set up with 6 Nvidia 1660 cards and it does some strange things. It appears from whatever information is available the limit on this board is 5 Nvidia cards! Seems to work with 6 (4 EVGA 1660 and 2 MSI 1660 Ventus) but when playing with the setups using MSI Afterburner the system will occasionally do strange things and crash.

So, I guess the 5 Nvidia limit on the H110 is real. What about the H81?
