Hi there,
I'm running a Sapphire HD 6970 with Phoenix under Windows 7 and I get around 430 MHash/s with this setup. I achieved this value by enabling ATI Overdrive in the ATI ControlCenter, raising the core clock to 935 MHz and setting the "Power Control setting" to +8%, mem clock stays untouched as higher values did not improve performance.
For various reasons I would like to mine under Linux, but as far as I can see, there's no way to set the "Power Control setting" under Linux!?
Sure, you can use the "aticonfig --odsc" command to set core and mem clock, but when doing so and setting the clocks to 935/1375, the overall performance decreases to a much lower MHash/s value, and it's exactly the same under Windows 7. The card seems to slow down on its own. The only way to avoid this is to raise the "Power Control setting", which is not available under Linux, neither as an aticonfig command nor in the CCC gui.
Does anybody know how to "set the card free" under Linux?
Thanks for your help!
