Well the improvements to the "boost lock" feature didn't do anything to help improve my max overclock as the voltage is still limited. Only noticeable changes I could see were it locked the memory clock to the max value (0.4.8.0 didn't do this), and it set the voltage slider all the way to 100% (0.4.8.0 didn't do this) which didn't allow the card to pull more voltage anyways, so setting it to 100% didn't help at all.
