Well, after further investigation.... mine is blown, too.
Let me describe what happened:
First set up DDR Booster and the LED jumps around a lot. I set it to like 3.0v and start to OC, I smelled the "electrical plume" smell, and checked it out, didn't see smoke, but the booster was quite warm. I shut it down and fired it back up. Ever since, it's worked fine up to 3.4v............
