What mining software are you using to get six U3 units working? Command line? Thanks.
cgminer --au3-freq 250 --au3-volt 830
bfgminer -S all --set antminer:voltage=x830 --set antminer:clock=250
Thanks for replying.
What version of BFGMiner are you using? I've never been able to get my U3's working with it.
They are not even recognized by BFGminer, no matter what settings I use. Are you using the SiLabs drivers?
