Hi all, I currently have
1 x r9 280x dc2T V2
2 x sapphire HD7970 OC with Boost
Crossfire only work when r9 280x & any of my HD7970,
Crossfire does not work when 2 HD7970 Crossfire.
"The AMD CrossFireX internal bridge interconnects linking your graphics cards together are not properly attached. Both bridge interconnects must be attached. For more information, see the user's guide for your graphics card."
I have 3 crossfire cable that came with the three cards and tried them all.
I have also tried resetting bios, clean install windows 7 & 8.1 64 bit, installing Catalyst 14.1 & 13.125, basically anything that I can think out that can be searched online.
Is there anymore solutions? Because I want to sell my r9 280x since crossfire will downclock the r9 280x anyways.
