Yep. Twiddle with the sliders in this tool and when you go back to CLI $aticonfig the limits have changed ... go figure.
That only makes it possible to go below the limits, not above.

Will this overclock past the BIOS limits?
No, it can't go over limits.
Does anybody know how to bypass limits without BIOS modification in linux?

You can use AMDOverdriveCtrl from the command line. Save a profile (.ovdr file) and pass the -b flag.
Does it need X to work, or can you use it at the command line, too ?
It is a command line program, but you need X running to see any error messages or warnings.
What do you use to tweak your ATI GPU settings in Ubuntu? And why?
It depends on what you're trying to tweak. If you're just looking to overclock then aticonfig will do it.
If you want to go more advanced and tweak voltage and lower clocks then you want AMDOverdriveCtl.
If you're using AMDOverdriveCtl you really need to understand your BIOS limits and voltages being supplied to the card so you don't damage it.
Thanks for that tip, grndzero!
Do you have a link to that AMDOverdriveCtl??? I can't find any reference to it on the net :S
right here:
http://sourceforge.net/projects/amdovdrvctrl/
great tool...

$aticonfig --adapter=0 --od-setclocks=770,1126
check out ...
$aticonfig --help
GUI based tools should be treated with caution when you are thrashing the GPUs as hard as you can under linux using a miner
Thanks for that moa!
And the --adapter value is the same as the "d" value for poclbm?
No, aticonfig use 0,1,2,...
and poclbm uses 1,2,3, ...
Just give it a
$aticonfig --list-adapters
or
$aticonfig --lsa
and it will list the adapters that the fglrx (the graphics driver) has intialised and aticonfig is 'seeing'.
