Hi everyone

just setup crossfire with 2 separate RX 570 brands 1st- red devil, 2nd- msi Armour

i got a better firestrike score with the red devil so decided to put it in the first pci x16 slot
i have the msi in the 8x, they are both on the same core - mem clock

atm my machine will use the msi as the main card for processing which is in the slower 8x slot

and i cant figure out why.....?? i know its using the msi card because of its TDP which is lower than the red devil, and rivatuner states GPU2

the obvious solution would be to stick the red devil in the second slot but
then it would be running at 8x ??

Any solutions would be very helpful as i'm new to Crossfire

links to screenshots in games with rivatuner

the monitor is connected to the first card x16 slot ?

on a side note

does this mobo support 2x16 PCIe https://www.asus.com/za/Motherboards/TUF-B350M-PLUS-GAMING/specifications/

because is see GPU-Z states the top card is running at 16x and the bottom is running at 4x
