Overclock Antminer U3 running on raspberry pi I have an Antminer u3 running on a raspberry pi using bfgminer. Its currently running at 47GH/s. Does anyone know if  is possible to over clock it using BGFminer so that it will run at 55 - 60 GH/s?

if i cant do it using BFGminer is there another mining software i can do it in?

any suggestions would be welcome and would be appreciated:)
I set up my rasp pi b+ and U3 mining rig using the instructions in this forum post, with screen and cgminer.

The command relevant to over clocking the raspi that I used is the following:

sudo ./cgminer --bmsc-options 115200:0.57 -o POOL -u USERNAME -p PASSWORD --bmsc-voltage 0800 --bmsc-freq 1286


Those last two options (bmsc-voltage and bmsc-freq) are what over clocked the rasp pi.  But I think I had to compile cgminer and configure it to include bmsc.  Mine typically runs with a hash rate in the high 50's or low 60's, but maybe not quite 62-63 GH/s.

Also, I did try to push the U3 voltage and frequency higher by playing with the settings as detailed in the U3 manual.  However, I could never get the U3 to run stably at settings any higher than what I gave above.  I'm not sure if it makes a difference, but I'm actually running two U3's on the one rasp pi and cgminer instance.

Update: In the interest of providing a complete answer in one place, here's the full text from the linked forum post:


  Run a fresh install of Raspbian using NOOBS, after the install type ifconfig and make a note of the IP address, so that you can remotely
  SSH into your Pi. Login via PuTTY with the default username/password,
  then raspi-config if you would like to change the hostname, default
  password and so on.
  
  Now update the Pi: 
  sudo apt-get update &amp;&amp; sudo apt-get upgrade
  
  Install dependencies: 
  
  sudo apt-get install libusb-1.0-0-dev libusb-1.0-0 libcurl4-openssl-dev libncurses5-dev libudev-dev screen libtool automake pkg-config libjansson-dev screen
  
  Clone cgminer from here: 
  git clone https://github.com/bitmaintech/cgminer
  
  Install, configure and also enable bmsc options: 
  
  cd cgminer
  
  sudo ./autogen.sh 
  
  export LIBCURL_CFLAGS=’-I/usr/include/curl’ 
  
  sudo ./configure --enable-bmsc
  
  sudo make
  
  Test cgminer is working correctly by running the following (input your
  own pool, username and password): 
  
  sudo ./cgminer --bmsc-options 115200:0.57 -o POOL -u USERNAME -p PASSWORD --bmsc-voltage 0800 --bmsc-freq 1286
  
  Type Q to exit cgminer...
  
  Now, add cgminer to start automatically when the Pi is powered on and
  create a screen session:
  
  sudo nano /etc/rc.local
  
  Remember, Ctrl-X to exit, then type Y and press Enter to save changes. Add this just above
  exit 0, again enter your own pool, username and password: 
  
  cd /home/pi/cgminer
  
  screen -dmS cgminer ./cgminer --bmsc-options 115200:0.57 -o POOL -u USERNAME -p PASSWORD --bmsc-voltage 0800 --bmsc-freq 1286
