Beta seems to be working great for me!

EDIT:  My only comment is that the hashrate seems to fluctuate quite a bit.  It'll be up to 61 GH/s, then drop back down to 51 GH/s, then back up a bit, etc.  Seems random, and not at all to do with temperature (if anything, the higher-temp one is running a bit faster on average).  Any ideas on why this might be?  It definitely seems slower than what I was getting with EasyMiner.  It's a good 20 GH/s short of what I was getting consistently with that.
