Thanks for the replies, i`ll give the google method a try!
I`ve just flashed the Ants with the latest firmware and so far, both units are doing 443 gh\s (2 hours in).
Even the one which would only do 420-430gh\s before. So, it can`t just be the beeping that they changed?
What version of CGMiner is it now running?
The same version as before 3.12.0-1.
After flashing my 5 S3's I had 1 unit that was doing 420 GH/s and now is doing 442 GH/s. Another unit was doing 440 GH/s and now it is doing 427 GH/s. Not sure what changed but that is kinda weird. All the units have been running for 3 hours since I flashed them.
I think these variations seeing after firmware update are coincidence.
