Problem running a legacy card and a new card

I currently use an RX 580 for my main monitor. I got it for free from a friend because he used it as a mining card so it only has one output. I have an AMD Ryzen 2600 and it has no integrated graphics so I bought a legacy card. It's an AMD Sapphire HD 5450 1GB. My only issue is that when I plug it in and run it it doesn't work. It is recognized in my bios and device manager. I took out my 580 and I was able to run the card no problem, i'm guessing this is an issue with the bios. Another problem I have is that my 580 seems to run worse when I have the old drivers for the HD 5450 installed. Any help or info is appreciated!

The HD 6000 series and earlier cannot be run with an HD 7000 series and newer card.
