Not a problem and basicaly yeppers.  You may want to do some digging in the different threads ( under hardware or search for S1 overclock ) and look in to the details on the overclocking/overvoltage.  I've got AntMiner U1s so for me it's a matter of powered USB  hubs ( protective diodes, Zeners, etc ) and possibly really fine soldering in of some 10k SMD 0603 resistors ( last is the size of the tiny things 0804 are barely doable with a fine tip soldering iron, 0603 is hot air and watch you don't literaly blow it off )

You may want to look in to removing the ' extra ' mining settings while you are at it.  I've got BFGMiner on a pc set up to mine at 2 different locations and there have been times that one pool seems unreachable and it won't go back to it for a few hours manually trying to get it back there.  In your case, it may go back to mining for ' the other guy ' which would do you no good.

Good to hear it's working and good luck with mining.
