Discussion created by serdar61 on Aug 25, 2017

How do I enable crossfire with 2x RX 580. I dont see crossfire in Global Settings section. I dont need a bridge or anything with the RX580's right?

Please help me I bought this gpu especially for Crossfire configuration.


I am running I7 4790k with ASUS maximus VII Hero motherboard (supports Crossfire) and windows 10 64bit



Tested the following drivers : crimson-relive-17.7.2 and Crimson-ReLive-17.8.2


Update: I also tried older drivers > 17.5.2 and 17.6.2 and nothing works

This is not a driver issue I think, I am using Corsair RM 850X psu, thats fine too. I attached the gpu's to x16 and x8 lane so that is correct too.

I need help here.
