After add a third card on this motherboard, the second one loses hashrate. After add the forth, the second and the third loses. The 4 cards are identicals.
Can anyone help me? What I'm missing?
What does PCIE_12V_1 do?
I'm using Windows 10 Home, this is a problem?
I have not installed the system on a UEFI partition, can this be?
