Hi,

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.

Problem:
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

You could always do two instances launching from two separate directories.

I'll try that.
I tried it allready, but from the same folder - there seemed to be some conflits with fan-speed. How do I make the cgminer to ignore one graphic card (not to turn it off or set low intensity, but just to ignore it)?
