I've literally spent most of a entire week playing around with settings and trying to find the sweet spot and I feel like I'm pretty much there. As you can see, I actually underclocked my cards to get these hashrates. Stock clocks are 1100 core/1500 memory. Unfortunately the default voltage is about 1.2 volts on my cards and its locked (@#&($$^(@&$!!), otherwise, I'd be able to save 100-150W easily by undervolting.

Is there a list of which cards are voltage unlocked anywhere? If not, would be a useful list to start, especially for LTC mining.
