2x rx 480 crossfire

[Always_Winter]

on a h170 mb asrock pro4s. 7600kgpu
i cant understand why the secondary card is always in low power mode making the clock 0mhz. how do i disable low powerr mode across the board so both cards can enjoy crossfire? regardless of wich one i make primary it always turns the other one eccentialy off sinze it reads as 300mhz or 0mhz.
