Hey guys!

I'v got a small problem with my CF PowerColor R9 280X TurboDuo OC cards. My first display is 27" WQHD and second is 24" FHD. First one is connected with DL DVI cable and second with HDMI cable. When my 24" is connected, upper GPU gets full voltage of 1.2 V and clocks go up to 500 MHz GPU and 1500 MHz MEM in idle state. Everything works fine with one display (0,85V 350 core and 150 mem) but adding the second one makes a bitt of a fuss.

Another thing. When I first set up my CF, GPU-Z was showing me full sensor information. Now after choosing second GPU in tab it begins to show all readings for 1 second, after that everything goes to 0 and GPU-Z is in ultra slow mode on the edge of hanging. In MSI AB sensors work, but I can not see VRM temps and the second GPU voltage.
