I am completely new to minig.
I have Radeon 5870 and 7970 in the same machine. I found out that 7970 gives higher khash when using --gpu-threads 2.
I am starting cgminer with .bat file in which I would like to set -g 2,1 (2 for 7970 (which is my first gpu), and 1 for 5870 (which is my second gpu)). But with -g 2,1 cgminer won't start. I only starts with -g 2, but in this case khash on 5870 is really slow.
How can I start one card with -g 2 and the other with -g 1.
Any help appreciated. Thanks
