x2 XFX RX Vega 64 and Crossfire

Question asked by twokillabytes on Mar 16, 2018

Hi everyone, I just want to ask if anyone who knows what this means. Everytime i enable crossfire mode on AMD Radeon Settings it would work fine for a few seconds and everything will start to lag really badly. (Mouse cursor skipping, etc) I have to hard reset my computer for everything to work fine again. One thing i noticed is that the LED on the GPU Tachometer on my second card turns to green and the RADEON logo turns off. Any idea how to fix the major lag when enabling crossfire mode and  what does the green led on the GPU Tachometer mean?
