Question AMD athlon x4 860k no boot using rx 570 4gb

[raph261]

good day, im having trouble when booting using my athlon x4 860k (fm2+) with rx 570 4gb. It shows no display at all, i tried swapping my 860k with amd's a4 6300 apu with the same motherboard and same gpu. It works perfectly(bottleneck aside). I did try gt 730 with 860k before and it works fine. What could be the possible problem?

thanks in advance
