according to the manual for that motherboard, it supports crossfire.
the RX 580 supports crossfire as well.
So in short, yes, but, both cards will run at the slowest cards speeds for GPU and VRAM, and you will only have access to 4 of the 8GB on the 8GB card.
If you can get another 4GB version for cheaper then do that and don't waste the money on the 8GB version.
If you already have purchased/gotten into your possession both of these cards then my last point is moot.
But of course I would say that you should double make sure you have a power supply that is up to the task of powering both cards at the same time.
