I have a rig with both nvidia and AMD graphic cards installed, using the nvidia to drive the display and play games and the AMD for mining.
The Nvidia card (gtx 460) is seen as device 1 by the system
The AMD card (R9 290) is device 0
When starting CG miner with -d 0 command I'm getting warnings. The card works but I've got no temp/fan information and cgminer doesn't have control over the power/temp regulators of the card. The same with MSI Afterburner, it sees the card but I've got no info and no controls. Catalyst Overdrive is greyed out.
I'm asking because maybe somebody has previous experience with this and can help in making it work.
EDIT: I'm guessing it's this problem?
4) For Windows to see the card, I plugged it into another monitor. Another way is too use a dummy plug:
http://www.overclock.net/t/384733/the-30-second-dummy-plug <- I personally haven't used this method yet, but I'm trying it tonight on a 6950 so wish me luck!
And then from there I just ran GUIMiner and selected the 7950 and it worked great. I'm trying to get CGMiner to work with it, and to disable the GTX 670 before it even starts, but I'm still working with that.
EDIT2: Pluging in the monitor on the Radeon, it powers up and the monitor turns on after a couple of seconds. Catalyst overdrive gets enabled. Probably everything else works too.
Problem is I don't have 2 monitors to be driven by both cards.
I need a software solution to prevent my secondary card (AMD) from going in "sleep mode". I remember reading somewhere this being a rather recent feature of catalyst drivers.
