Hello,

I have a later model (6xxx) graphics card and I have been struggling to get beyond their bios established voltage and clock ratings.

I tried for about a week to get passed 840mhz for the core in linux distros, but it seems impossible.  I tried a few times to modify the bios in RBE and then flash the card using 'method 2' but both attempts I kept getting instant crashes.  ATI tray tools and msi afterburner both work great, however they both are extremely limited.  Their software ability is robust but how many cards they can handle are not.  As far as I know, ATI tray tools can only handle 2 cards at a time where msi afterburner is only capable of handling 3.

This makes overclocking very difficult if you are using a 4-6 card setup, and impossible in linux.

Does anyone have any knowledge they'd be willing to share on how to get passed the bios rated limit in linux?

I've searched, tried, and yelled this idea to death alone.

Thanks
