Topic: Overclock/underclock Radeon 5970/5870 Linux outside BIOS Limits? - page 2. (Read 10078 times)

I believe this is because we cannot, yet, easily change the voltages.  So we can't overclock too high, or the card needs more voltage than the core is providing.

Please check this, i wrote step by step guide after it worked for me.

I can confirm that with Ubuntu 11.04 and Catalyst 11.6 you can OC/UC beyond the limits.


I can go higher with the Core MHz, but last time two of my mining instances froze after some time, so I'm using the lower MHz right now until I find the sweetspot.



$ aticonfig --odgc --adapter=all

Adapter 0 - ATI Radeon HD 5800 Series
                            Core (MHz)    Memory (MHz)
           Current Clocks :    900           300
             Current Peak :    900           300
  Configurable Peak Range : [600-900]     [900-1300]
                 GPU load :    99%

Adapter 1 - AMD Radeon HD 6800 Series
                            Core (MHz)    Memory (MHz)
           Current Clocks :    1000           1150
             Current Peak :    1000           300
  Configurable Peak Range : [775-1000]     [1150-1250]
                 GPU load :    99%

Adapter 2 - AMD Radeon HD 6800 Series
                            Core (MHz)    Memory (MHz)
           Current Clocks :    1000           1150
             Current Peak :    1000           300
  Configurable Peak Range : [775-1000]     [1150-1250]
                 GPU load :    99%


And this is the simple script that allows for easy OC with my cards (just put that adjusted for your gpus in any .sh file):

aticonfig --odsc=900,300 --adapter=0
aticonfig --odsc=1000,300 --adapter=1
aticonfig --odsc=1000,300 --adapter=2

And if you do, take a look at my signature please

I messed up trying to uninstall 11.5 and install 11.6 somehow and am now waiting for Linuxcoin 0.2b which has 11.6 setup.

I wish I could be more helpful, but had a hard time getting 11.6 installed properly after having ubuntu installed ATI drivers.
However, if you go to the AMD driver download page and look through the release notes link, it has instructions on how to uninstall the old drivers and install the new ones.  I wound up deactivating the ubuntu-installed ATI drivers under SYSTEM, HARDWARE DRIVERS and running the general 11.6 install.  It wouldn't run aticonfig because I think the ubuntu install sets unusual file structures in place that the ATI  generic install doesn't undo, somehow.  Eventually, I went back to activating the ubuntu-installed ATI drivers and got my overclocks, so I was content.
I should have tried searching more.  Here's a wiki that details how to get 11.6 on 11.04, including a section on how to remove the ubuntu-installed driver config:
http://wiki.cchtml.com/index.php/Ubuntu_Natty_Installation_Guide

Can any one tell how to install 11.6 in Ubuntu 11.04. With Inaba guide i am able to install & mine with Ubuntu 11.04. It has catalyst version 11.5.

How to install 11.6 in to Ubuntu 11.04?
Help is much appreciated as 11.5 don't allow to reduce memory clock which is increasing temperature too much.
I tried with AMD site & got this file ati-driver-installer-11-6-x86.x86_64.run.
Don't know exactly what to do next.

This is great news, if Catalyst 11.6 can get my non-reference card past its limits!

I'm running Linuxcoin and need to de-install the current drivers and download and install the new ones, which I will try and post here how to do it.

I started using Radeonvolt on both my 5970 and 5870 cards with no issue, only working on reference designs though.

Yea, that appears to still require RBE from DOS and a BIOS Flash.  Sigh.

now if we could just figure out how to adjust voltage outside bios limit we would be golden.

Downloaded and installed on my new rig.  Confirmed, allowed me to set GPU and RAM outside of the listed ranges.

SUCH good news.

Yess thank you

Fail:  "2) Use it to create a FreeDOS bootable thumb drive."

This thread is about doing it from Linux, natively.

This.

AMD very strongly recommends uninstalling before updating.

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?

I just installed Catalyst 11.6 on Linux (Ubuntu 11.04) and my XFX is still limited by BIOS settings. 11.6 does NOT allow me to go beyond bios settings.

Ok, I stand corrected. It does work.

Any luck in moving the voltage without flashing the BIOS?  I was able to confirm that the GPU clock was able to move above the limits I saw on the previous version.

Donation not needed but:

I'm just happy that AMD released a version of the Linux drivers which allows us to change settings outside of the BIOS limits.  Seemed really odd they let us in Windows but not Linux...
