Hey guys !

So i got that U3 who just stop sometimes ( in cgminer 4.9.2 , only mhz is show , not the volt ... ) also detect as a blockrupter (?) , sometimes not detect at all , and when is detect got only 29gh/s , is that normal or this lil thing is dead ?

--au3-freq 237.5  --au3-volt 800 for the conf , i tried lower volt and freq , but still got this problem ..

(sorry for bad english  Smiley )
