Color profile warning is irrelevant.

Thanks for the numerous responses!
@frozen: This is a headless setup - so no monitor attached => no GUI :S
@Monoquark: yes, I did try that, no change to the problem
@exahash: My understanding is that the program should return to shell when it executed correctly as it -b stands for "batch mode". It seems as if something from the update process is hanging and is not allowed to finish.
aticonfig --odgc --adapter=all still displays the original threshold (900mhz). I've used the script like that which should be a valid configuration (the 3 settings at the top represent the settings current in effect, the lower ones are the settings I want to apply.. still it hangs):
I wonder if the "color temperature" warning is relevant although I did not specify anything like that in the config file.
---------
That is the point while writing when I realize that there are actually predefined .ovdr files located in /root/.AMDOverdriveCtrl/ ...
>_<
until now I've tried to apply other scripts I found in the forum which indeed seemd to be the problem as the voltage cannot be changed..
Thanks again for all replies.. when I have tested more thoroghly I might post an easy to understand tutorial.

Try -i 0 , 3, 6, and 9. Other than that your .ovdr looks pretty good AFAICT.

Can you use AMDovrdrvctrl to tweak voltages on non reference GPU's? I am not having any luck finding something that will let me tweak my voltages in Linux like I can in Ubuntu.

It's hanging because it's putting an error message up on the console. It's ok to do a ctrl-c when that happens.
What does "aticonfig --odgc --adapter=all" show after you run your AMDOverdriveCtrl command? You should always use that to see whether your AMDOverdriveCtrl settings took or not.
Looking at your config file, I'm guessing AMDOverdriveCtrl doesn't like you changing the voltage, even by .003 volts, and/or that 150 is too low for your mem clock.
I ran into the same exact problems when I started playing with AMDOverdriveCtrl.
Try copying your default.ovdr and changing only the mem clocks in it (set all three levels to 30000) - don't touch anything else, you want the GPU clocks and voltages stock to test - and see if it will load.
After that, try tweaking the GPU clocks. Wait to touch the voltage till last. If you don't have a reference card, AMDOverdriveCtrl probably won't be able to tweak the voltages.

The 5830's I am using are in fact flashed, but I recall being able to underclock to 300Mhz even before that.
Are you able to open up AMDOverdriveCtrl normally and underclock the memory from GUI interface?

Well I know I could flash the bios but there is a clearly higher risk of breaking stuff.
So I'd prefer to simply perform this changes on system startup where I just need to comment out a script to have the normal settings in effect.

You will have the best of luck booting into windows and using "RBE".
Look it up, far too much to explain here and they have a great tutorial on their website.

Hey there,
atm I am running my 5830 @ 975/900 because this is the lowest memory clock aticonfig will let me go.
I am using a ubuntu 11 headless setup.
I've read that some ppl were able to lower the aticonfig threshold via AMDOverdriveCtrl, however I had no luck.
My config file looks similar to this:
When I execute it it simply hangs while trying to apply the settings:
There is actually no further output after the last line and the script continues to run (=> does not return to the shell).
Any ideas?

Any ideas?
