Hello everyone, i have a mobo with 4 pcie x1 and 2 pcie x16, i tried to connect my 5 RX 480, but if i connect just one of them in the pcie x16 slot afterburner wont let me overclock and in fact the hash rate during the ETH mining is very poor but if im only use the 4 pcie x1 everything i smooth and fine.

i dont know if i have setup something in the Bios for fix this issue, please help!!

Thanks!
