Thanks for the links, I'll study that. It seems that it's the link of znort which was I was looking for.

Changing this setting made, for me, an augmentation of about 20%.

thank you, but do you know if it's exists in a command-line version? Or as it seems to be a gui for aticonfig, the parameters to set for controling that is called "power control" on Catalyst's windows gui, where value can vary between -20 to 20.

The miner is on a remote server, and I've some issues to install vnc...

Hello,

I've a hd6990 and I've reached 790Mh/s on windows with the Diablo's miner, and I'd like to get the same results on linux but I don't find how to set the power control at the maximum value as it's possible on the Catalyst gui.
Could you help me?
