I've got both cards properly detected in GPU-Z, but I am not able to run cgminer at all now. I don't understand the readme at all, how do I configure it to "look" for two graphics cards? Is there a good tutorial at anywhere on how to use this? Google lead me to find this command which gave the info, referring to -ndevs

So, I have only one 5900 in there, seems like its detecting two (as well as GPU-z?). How do I set this up, so I can choose settings for each card i ndividually? I assume its not optimal to use
-I 13 -g 2 -w 256 --lookup-gap 2 --thread-concurrency 8192 --gpu-engine 1000 --gpu-memclock 1500 --temp-target 70 --auto-fan --gpu-powertune 20
for both of these cards? I tried to run this and I got instant artifacts and had to manually power down. Help is appreciated : )
I used to have issues when i tried using cgminer on its own but since ive moved to guiminer-scrypt, which used cgminer in the background ive never had an issue, I could never understand why this was the case but hey! if its not broke, dont fix it.
If you try downloading guiminer-script you should find it much easier.
