Problem mining with Radeon 5970 cgminer

[honorthebtc]

I ll post here until i'm unlocked on other sections :

I have a nvidia GTX 670 as device 0, main GPU that i don't want to mine with,
and a Radeon 5970 as device 1, with a dummy plug. (this GPU has 2 cores)

I installed the lastest cgminer, AMD SDK and catalyst.
I'm using Windows 8.1 64bit

i use the command line : cgminer --scrypt -d 1 -I 10 -o "pool infos"

When i run the .bat, the cgminer screen goes black.
On GPU-Z, i see that one core of the 5970 is working, but the other core is at 0%.

Can anyone help me? I want the GPU to work on both core ofc.

Thanks!

Have you tried to run cgminer.exe by itself? What version of cgminer are you using?

[honorthebtc]

CGminer : 3.7.2
SDK 2.9 (also tried 2.6)
Catalyst 13.11

CGminer worked great with only the Nvidia GTX 670 (low hash rate but everything was working).

Same problem here. Did you fix it?

You need to let cgminer know what to look at, I've got a 660ti not mining and some Radeons in the other plugs --gpu-platform 1 points cgminer to the second plug and so on.

Hope it helps.

I'm sorry for my english.
With my 5790 i can mine with one core without export display,
but when I do export I can't mine. My rig don't start.
I'm on Xubuntu 12.04, catalyst 12.8, cgminer 2.11.4, psu 850W
Thanks
