HI with crossfire enabled I get silver streaks through my screen and game play is very jerky like major lag and that's on wow,skyrim with 80+ mods ,elder scrolls online and borderlands the pre-sequel and even Netflix.
I recently had to update my system so i have a hodgepodge of old and new , originally I thought when my system crashed it damaged one of my GPU's so I swamped them and tested them with 3DMARK fire strike 1.1 and the score's were close 5686 & 5684 so i thank the cards are fine but with crossfire on the score drops to 3752 !!!!???? yeah go figure . AMD auto detect clams i have the latest drivers, 15.3 I did not have this problem before with the old drivers version I thank it was 14.7 but not positive but that was with my old motherboard and cpu phenom II x6 1100t black ,this is my new system.
motherboard = M5A99(FX PRO P2.0
CPU Fx - 9370 collier corsair H100i
ram HiperX fury 16g 1833mhz
GPU sapphire 77870xt x2
pcu rosewill capstone 1000w
windows 7 64bit
Ow I also tried installing the 16.1 hot fix but windows wouldn't let me it Sade it was corrupted ??. Any suggestions or should I just say the hell with crossfire and get a R9 or GTX 980 =(
