gpu0 is plugged into the monitor or it is the default primary gpu and will always be free to mine on. gpu 1,2,3,4... and so on are secondary and need dummy plugs for the most part. Others on the forums have stated that they do not need dummy plugs with 11.7 but i found that it is still a good idea. Try installing 11.6 and see if that creates a stable environment. What power supply are you using to power those cards?

Thanks,

Any ideas why it would work with Aero on and GPU 0 not mining and there is no dummy plug? Sorry to sound so vapid, but I'm not sure what the interactions here are.

make sure to turn off areo. i also noticed that if i use 11.7 without dummy plugs it locks.

I guess, just a lot of schlep. Would probably work though, thanks.

Hi folks,

I have 2 x 6990s (so 4 GPUs) running Windows 7, Catalyst 11.7, GuiMiner (newest one)

The miner keeps locking up if I activate GPU 0.

I have set the clock back down but the cards are still bios oc'd and at +20% power under AMD Catalyst. That did not work.
The problem started shortly after upgrading from Catalyst 11.4

Please help or give suggestions
