    Is it possible to set idle and 3D clocks in a CCC profile (manually editing the xml file)? I just noticed the clock and voltage settings in a profile xml. I know it's possible for a BIOS flash to do this, but seeing as I don't have an old PCI card to repair a possibly bricked card, I don't want to do this.
    Here's the relevant part of the xml:
    </Feature>
    <Feature name="CoreClockTarget_1">
    <Property name="Want_0" value="50000" />
    <Property name="Want_1" value="50000" />
    <Property name="Want_2" value="78000" />
    </Feature>
    <Feature name="MemoryClockTarget_1">
    <Property name="Want_0" value="45000" />
    <Property name="Want_1" value="45000" />
    <Property name="Want_2" value="90000" />
    </Feature>
    <Feature name="CoreVoltageTarget_0">
    <Property name="Want_0" value="1263" />
    <Property name="Want_1" value="1263" />
    <Property name="Want_2" value="1263" />
    </Feature>
    <Feature name="MemoryVoltageTarget_0">
    <Property name="Want_0" value="0" />
    <Property name="Want_1" value="0" />
    <Property name="Want_2" value="0" />

    As you may or may not notice, I changed the first two memory clocks to their minimal allowed value in CCC, and the 3D core clock is set to 780 instead of 750. This last one works, but the memory clocks don't work. Even if I use this profile and load it, memory stays at 900 MHz.
    The reason I want to do this is to limit the power consumption of my PC when not gaming. Any help is appreciated!

    only works within limits that bios has, use gpu-z and rbe to see what usable values u got, same goes with voltages, think u can go below 1 with idle
