Just remembered to try out the titan kernel.. good thing I did! Should have done that directly from the start haha, completely forgot. Runs about 10% faster with T12x32 compared to K12x32 on my 780, seems to draw less power too! Good stuff.
With the core at 1110, mem default, I'm at a nice even ~550khash/s now, doesn't need any overvolting for that.
