    i want to underclock my card through ccc profiles

    i have a slight idea on how to do it but i need more advice

    <Feature name="FanSpeedRPMTarget_0">
    <Property name="Want" value="0" />
    <Feature name="FanSpeedPercentTarget_0">
    <Property name="Want" value="30" />

    this is my normal code

    I'm thinking of underclocking by changing the core clock target value
    this would work, right?

    what would happen if i reduce the core voltage target ?
    would the card crash and turn into a 800sp brick?

    Please advice
