antMiner_S320141126.bin don't surpport adjust voltage. Hash board's power maybe cut off when you over clock.
antMiner_S320141126.bin doesn't support anything at all - it is broken.
Read all the reports about it.
Remove it from your download site - then release a properly tested firmware that works!+100!!
@ Bitmain:How about taking that piece of junk firmware off your website before someone else makes the same mistake I did & tries to update their S3's with it?
I just spent 4 hours upgrading then downgrading all my S3's because, once again, you release firmware that is completely untested.
One is not amused

@
Bitmain,Do you even read this thread? Just scroll back a few pages & catch up a bit. In fact, you can see from most of your threads that this firmware is another botched together piece of junk.
Get rid of it.
