Ok, after AMD driver update, changing monitor to internal graphics card, and messing around with settings I was able to easily get over 800kh/s.
But, for some reason when I removed the monitor from the R9 and changed it to internal output in the motherboard, neither GPU Tweak nor MSI Afterburner detects any cards at all??? Why's this? I mean; CGminer sees cards just fine, but these tuning apps do not.
