How do you get passed bios limitations for overclocking a GPU?

[pinjas]

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

the 11.6 drivers will let you use aticonfig to set clocks outside the normal config range.

I guess I don't understand how.  I've used 11.6 plenty, but I've never had success getting passed the 'normal' range.  Is there a list of commands?  I use things like "aticonfig --od-enable" "aticonfig --odsc=GPU,mem" "aticonfig --odgc" and so on, but I don't seem to be able to get that to work.

Flash bios? Use rbe to change the range

I tried that a few times myself, I got instant bsod, thankfully the cards have that bios switch.  I assume you are talking about method 2 on the additional features tab.

Yes, method 2. I tried that on all my 5830(no bios switch) and it worked just fine

I guess it's possible that Catalyst 11.6 only breaks BIOS limits for older cards.  With my two non-reference 5850s Catalyst 11.5 limits me to 900 MHz core clock and 1.0875V.  With Catalyst 11.6 I can go to at least 1140 core clock (not pushed it further) and to a new limit of 1.3V.  I can use 'aticonfig --odsc' to push the core clocks past the BIOS limit and didn't have to do anything special (used AMDOverdriveCtrl for the voltage).  Perhaps it just doesn't work with the HD6xxx cards.

Code:

aticonfig --od-enable

aticonfig --odsc=900,300 --adapter=all

change 900,300 for what your lookingto change your gpu and mem clocks.

if your running multi cards just choose the adapter instead of all.
