Catalyst 11.6 in Linux allows you to bypass the BIOS limits now. 11.5 didn't.

Code:
Adapter 0 - ATI Radeon HD 5800 Series
                            Core (MHz)    Memory (MHz)
           Current Clocks :    975           300
             Current Peak :    975           300
  Configurable Peak Range : [600-875]     [900-1200]
                 GPU load :    99%

I've tested it on both Sapphire and Gigabyte 5830 cards.

Whoa!  Really?  I have four Sapphire Radeon HD 5830s that I am going to try this on tonight.  Thanks for the tip!

Do I need to uninstall the 11.5 Catalyst drivers first, or do I just install the 11.6 drivers in the usual way and trust them to overwrite everything appropriately?
