Yesterday my 25GH/s Miner from Butterfly that mined at about 26,5 GH/s went down to about 21 GH/s, now i saw with bfgminer that 2 chips aren't working anymore. Any Hints on that?

Bye

Did you recently cycle power on it? I know a few people who have miners that slow down when that happens. Easiest thing to do in my opinion is to unplug it and set it in your fridge or outside(if you are in a cold climate) for 5-10 minutes then power it back up and see if your chips come back.
