Hi all,
I am running two Red Devil 580x GPUs (8GB) on a computer which I was previously running two gpus off of (FURYX + 7850). After upgrading the 7850 with a spare red devil (powercolor 580 before that, Nitro FuryX before that, etc) I cannot get the second GPU to output video, and a quarter of the time not display temps in MSI Afterburner. It does display/register as being in afterburner as existing, drivers work, but does not appear in windows screen resolution or a program like OBS. I can find it and use it (and every other GPU I've put in there) for cryptomining programs. Yet everytime I connect via HDMI/VGA-HDMI connector/Display port-HDMI etc, it doesn't display.
This is driving me nuts so hopefully someone has an idea.
All the cards work in other systems just fine, and barring display output, on this rig as well for mining/showing up in windows device manager. Also to note, for some reason GPU (both) FB usage is always pegged to 100% when reporting in AB, wether idle, gaming, streaming etc.
Using Windows 7, i7-3770K, Z77 Extreme 4 Mobo, 2x Red Devil 580X 8GB.
