CPU: AMD FX-8320E@4.2GHz (Very stable,tested with Prime95 for 12 hours)
RAM: 10GB DDR3 1333MHz
GPU1: Sapphire NITRO R9 380 factory OCed
GPU2: Sapphire NITRO R9 380 factory OCed
PSU: CWT PUQ 750W
OS: Windows 7 64Bit SP1
Driver: Crimson Relive 17.3.1
Today i installed a second R9 380,
I reinstalled the drivers using DDU,I tried also 16.3, 17.4.2, and 17.5.2 (same results)
The problems are:
1.Crossfire profiles have no effect or negative scailing,sometimes with glitches and flickering in supported games.
2.Optimize 1x1 and AFR compatible have only an effect of negative scaling.
3.The only working option is AFR friendly which works in very small amount of titles, and it's always full of glitches and flickering.

Thanks for everyone willing to help
