Hi all, it's Eva 
Was playing around in CCC and noticed a few things:
"auto-tune" automatically changes the voltage to your card through the profiles.
In Windows Xp go to:
C:\Documents and Settings\(Your User Name)\Local Settings\Application Data\ATI\ACE
or in Vista
C:\Users\(User Name)\AppData\Local\ATI\ACE
and right-click a profile and hit "Edit"
Here's an explanation of a few settings:
The below are the speeds of your gpu processing core.
<Feature name="CoreClockTarget_0">
<Property name="Want_0" value="50000" />
<Property name="Want_1" value="65000" />
<Property name="Want_2" value="65000" />
</Feature>
The "Want_0" value is the clock of your card while running 2D applications, or ones with a low need for processing
The "want_1" value is the clock of your card while running simple 3D applications, with a low need for processing.
The "Want_2" value is the clock of your card while running intese 3D applications, sush as gaming, or ones with a high need of proccessing. Also 2D programs that use more "power" than the above two use this setting.
**The settings here are in the following format: 50000=500Mhz (drop last 2 zeros)
The below are the Voltages given to the gpu proccessing core:
<Feature name="CoreVoltageTarget_0">
<Property name="Want_0" value="1046" />
<Property name="Want_1" value="1046" />
<Property name="Want_2" value="1082" />
</Feature>
The "want_0/1/2" are the values corresponding to the above situations (2d/3d/intense3d)
**The settings here are in the following format: 1046=1.046 (Decimal after first digit)
~~Do not increase values past "1200" which would equal 1.2 Volts
This will create a lot of heat and it is recommended to increase fan speed via:
<Feature name="FanSpeedProtocol_0">
<Property name="FanSpeedProtocolProperty" value="Percent" />
</Feature>
<Feature name="FanSpeedAlgorithm_0">
<Property name="FanSpeedAlgorithm" value="Automatic" />
</Feature>
<Feature name="FanSpeedRPMTarget_0">
<Property name="Want" value="0" />
</Feature>
<Feature name="FanSpeedPercentTarget_0">
<Property name="Want" value="25" />
-change <Property name="FanSpeedAlgorithm" value="Automatic" />
............to
............<Property name="FanSpeedAlgorithm" value="Manual" />
Note: You can leave it on automatic. FanSpeedPercentTarget from 25 to 55 should still work. However, this will not fully help idle temps
-change <Property name="Want" value="25" />
............to
............<Property name="Want" value="55" /> (or any other numerical value)
-save and exit the xml file

With a boost to voltage to 1.175 volts I was easily able to hit 700 Mhz
But I still could not pass 700 Mhz (setting at 705Mhz but only hits 700Mhz)
I used 16 bit format purely to save space. I am currently trying to get my card pass 700 Mhz just to prove that it can be done, to open up the possibility of further Oc's.
Im also checking out other options that can be changed through the CCC profiles.
Sorry if any of this has been posted already but this I looked and I feel as if this isn't "out there"
Also please remember if you have 2 cards (like in do running in Xfire) to change all the settings for Setting_0 also for Setting_1 keeping everything THE SAME!
Recap:
It is possible to:
~Change voltages up to 1.2 Volts through a profile
~Change Core speed up to 700 Mhz (as of now)
~Change fan speed to cool your beast
It is NOT possible to:
~Change voltages past 1.2 Volts through a profile
~Get the core to go past 700 Mhz (as of now)
