What have you done?
What risers and psu do you have? No Risers. 2 RX 570. PCIe slot 16_1 and PCIe 16_2

Aha i see, it should work out of the box then...
do you have a ryzen cpu installed or a 7th Generation A-series/Athlon?
If you have a Ryzen installed you should be able to run at x8 + x4
If you dont have ryzen it wont work.
