Thanks for the responses.  Radeonvolt, I think I can change some settings before I compile as root and it might work.  atitweak is a very nice tool, however, the 1.175 voltage remains same when I check status.  I will try RBE when I really need it.  The cards undervolt easily with MSI afterburner on Windows.  The 5830 voltage sticks with radeonvolt.

Try atitweak:

if it can be overclocked/undervolted, it will do that. If this does not work, then you need a BIOS flash with RBE. I always try to avoid that.

I've had 6850 some time ago, and yes, it was possible to edit voltages via RBE. Not the frequencies, though. Just edit values in the "gpu registers" menu.

I have a 6870 card and AMDOverclockCtrl does not allow me to change the voltage on this card.  I tried Radeonvolt without luck.  I would like to use the mid-level settings on the card.  Is there any way to use aticonfig to force the card to use the mid-level settings.  Is there another tool?  Can I use RBE someway to  underclock the voltage?

Thanks
