just wanted to report that all nine of my S3 ants have been running flawlessly at 500+g/hs all month long.
i have not had to reboot a single one of them for the last three weeks.
my S3 ant farm colony is running as stable and strong as the my S1's.
of course i did make some mods before i started running them.
the above screenshot is what i see every day all the time without any reboots.
thanks bitmain for the great miners!
would also be interested how you mod them to get that high hashrate stable...

I'm interested too on the mods. I had mods some GPU with a great gain (decoupling capacitors...Step down converter...).
