    for unlock intend the possibility of set the frequency up to 840-1325.
    I'have a couple of 6950 in crossfire modded at 6970 and i want set the frequency of 6970:
    880-1375.

    Thanks

    Don't know what you mean by "unlock" CCC, but benchmark3d has modded drivers that enable some features only active with 7000 series cards (CCC will recognize the card as a 7900 series card and enable some extra stuff plus a little bit of performace improvements as well).

    MSI Afterburner is prob the easiest way.

    i'have always used ccc, with release 12.4 i had the limit of frequency in ccc 1620-2500, but i had used asus smart doctor to unlock this.
    Is there any other way to solve this problem?
    i don't want use msi afterburner because cause stuttering...

    AB doesn't cause stuttering.

    You can edit the profile.xml but it's a lot simpler to use afterburner.

    Btw your specs need updating...

    AB does not cause stuttering crossfire does.
    But +1 on AB its light enough and alot less buggy than smart doctor. for unlocking AB check the sticky in the amd gpu section.

    theres a registry hack known as racer x..thats what i use to increase the upper limits..google 'racer x catalyst' and you'l find it..with that you wont need to unlock unofficial mode in afterburner

    Create a .txt file with the following. (just copy/paste this to your new .txt file)
    Now, see the first line that reads.... [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Class\{4D36E968-E325-11CE-BFC1-08002BE10318}\0000]
    That \0000 is what you have to figure out for you machine, you need to know if your card is listed as \0000 , \0001 or \0002 etc..etc.. in your registry and edit that line to match.

    To do that....
    Open the registry by typing regedit in the run box and look for the following reg entry...
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Class\{4D36E968-E325-11CE-BFC1-08002BE10318}
    Under this will be at least one key named 0000, and possibly others listed as 0001, 0002, etc..
    What you want is to expand any or all of those.
    One of them (or if crossfired two of them will), will have a bunch of other sub keys including some or all of the following in them:
    ATI WDM Configurations
    DAL2_DATA__2_0
    Settings
    UMD
    VolatileSettings

    The keys with those sub entries are the ones for your card/cards.

    Example on my pc:
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Class\{4D36E968-E325-11CE-BFC1-08002BE10318}\0001

    This subkey, \0001 has all the sub entries listed above.
    I also have two cards in crossfire, so i had those sub entries under \0002 also.

    So, i needed to edit that first line to have \0001 at the end.
    And again with \0002 for my second card.

    Once you figured out whether your card/cards is \0000,\0001 or \0002 and edited the .txt file to match, just change the extension of the .txt file to .reg and right click it and merge with the registry.

    Reboot, and you have CCC overclock settings fully unlocked.


    I made one with [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Class\{4D36E968-E325-11CE-BFC1-08002BE10318}\0001]
    And one with [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Class\{4D36E968-E325-11CE-BFC1-08002BE10318}\0002]
    Changed them from .txt to .reg and merged them.
    Now i just merge those two reg files when i update my drivers.

    Of course your cards may not be 0001 and 0002 like mine, but that is easy to look up like instructed above.

    Note: keep the reg files for future use, so if you "clean" your pc when updating drivers, you can just merge the reg files again to unlock CCC if needed
