How To Overclock Antminer U1

To start overclocking the Antminer you will have to use a modified cgminer, you can get it here https://github.com/AntMiner/AntGen1 

./cgminer --bmsc-options 115200:20 --bmsc-freq 0781 -o YOUR POOL URL -u WORKERNAME -p WORKER PASSWORD

with these setting you get stock hashrate of 1.6GH/s

./cgminer --bmsc-options 115200:20 --bmsc-freq 0881 -o YOUR POOL URL -u WORKERNAME -p WORKER PASSWORD

with these setting you get stock hashrate between 1.6GH/s and 1.8GH/s

./cgminer --bmsc-options 115200:20 --bmsc-freq 0981 -o YOUR POOL URL -u WORKERNAME -p WORKER PASSWORD

with these setting you get stock hashrate of 2GH/s

Please be aware when you overclock them warranty will void (terms of us from the manufacturer) and you always should use proper cooling like a USB fan. The standard factory setting is bmsc-freq 0781.
