AMDOverdriveCtrl + 5870

[gdomod]

Hi i build my first minign rig with Debian 6 Server.

Packages:
Debians 6
SDK 2.4
ATI Catalyst 11.5

Ovdr Profil:

<OVERDRIVE_PROFILE>
  <PERFORMANCE_LEVEL level="2" gpu="100000" mem="30000" voltage="1088"/>
  <PERFORMANCE_LEVEL level="1" gpu="55000" mem="30000" voltage="1038"/>
  <PERFORMANCE_LEVEL level="0" gpu="15700" mem="30000" voltage="1000"/>
  <FAN_SETTING percentage="100"/>
  <FAN_CTRL enabled="no"/>
</OVERDRIVE_PROFILE>

And startup 

DISPLAY=:0 /usr/bin/AMDOverdriveCtrl -i 0 -b s0g0.ovdr & aticonfig --od-setclocks=875,300 --adapter=0

All works fine but i cant underclock my mem of 5870.
I install AMDOverdriveCtrl the settings are load fine

...
ACT: Fan speed set to 100%
ACT: SetOverdriveValues: Level 0: 157MHz, 300MHz, MHz, 1V
ACT: SetOverdriveValues: Level 1: 550MHz, 300MHz, MHz, 1.038V
ACT: SetOverdriveValues: Level 2: 1000MHz, 300MHz, MHz, 1.088V

But the odgc output change nothing

Adapter 0 - ATI Radeon HD 5800 Series
                            Core (MHz)    Memory (MHz)
           Current Clocks :    875           1000
             Current Peak :    875           1000
  Configurable Peak Range : [600-900]     [900-1300]
                 GPU load :    99%

The interval for your mem is [900-1300] , meaning that you will only be able to uc/oc to 900 or max 1300. Anything else will not be applied. Same goes for Core.

Sad to say, but you could do like me, flash the card in win with settings that you know work or have stresstested and then you should be able to uc/oc further (within the interval). Sadly I have not tested how the interval is changed if for example you would flash it wíth 920/300.
