Can't using rx470 with 280x

[amuleth]

Today I bought a new Asus rx470. I put together but I cannot use both of them at the same. If I plug in the connectors of 280x, 470 gives black screen. I can only use it when I plug out 280x. I use the 750 w power supply. Is the problem related with this? Or what else? (MBO: Asus Z77A - Win 7))

I know with simplemining and ethOS they do not recommend mixing card generations due to different drivers they each use. Not too sure on windows but it sounds like a driver conflict. Have you checked in device manager to make sure Windows isnt raising any red flags about the drivers?

I updated to latest drivers and it works now. Thanks!
