Ya, it works on 6990.

http://sourceforge.net/projects/amdovdrvctrl/files/

I think in Ubuntu, you can just grab a .deb binary and off you go.

I had to rebuild from source for Fedora.

o thanks

do you how i download it and install it with SSH? i don't have monitor and keyboard on my mining rig..

sorry for off topic posts.

No, not clocktweak.

There's an aticonfig binary in Linux. Here's an example of how to use it:

aticonfig --odgc

This will print your available GPUs and their usable ranges.

aticonfig --odsc 1025,300

This will set your CPU clock to 1025, memory to 300.

aticonfig --odcc

This commits the change you just made. The command above has little to no effect without this.

I assumed this was available in Windows, but I guess not.

You can get an Ubuntu package of AMDOverDriveCtrl that will let you (sometimes) set values above and below the floor/ceiling shown by aticonfig.

thanks
will this work on my 6990? and how and where do i get AMDOverDriveCtrl?

Is it possibly to keep a main card at higher memory and other cards at lower memory? I'm putting a gaming / mining rig together and I want one card able to game, but the other 2 will be dedicated to mining.

When you use Trixx, under settings, choose or make sure to check Synchronize for Multi-GPU config. Make sure to also download the latest version 4.0.1. I did not have issues even with crossfired setups. Using AMD Catalyst 11.6 RC2 and OCL 2.4 SDK.

Change the master card selected in MSI Afterburner (settings -> master graphics processor selection).

only works to get at 500 not 180

Switch the master cards again, and the application should update the slider for the new clock setting.

Tutorials, guidelines, optimizations for all!

make sure you have msi afterburner...then..

[ATIADLHAL]
UnofficialOverclockingEULA = I confirm that I am aware of unofficial overclocking limitations and fully understand that MSI will not provide me any support on it
UnofficialOverclockingMode = 1
AccessibilityCheckingPeriod = 0

It's in the bottom of the MSIAfterburner.cfg file.
Should be located in the folder where you installed MSI Afterburner

For MSI Afterburner, move the memory slider to 500, and then close down and restart MSI Afterburner. You should now be able to move the slider to 250. Each time you adjust the slider lower, MSI Afterburner will adjust the slider values when it is closed and restarted.
