Antminer U2 4ghs Overclocking

[kmaikaza]

 Well i did all the steps but no progress

  I did the voltage mod 5k/10k getting 1.19v on output.

  Mounted it on a huge cooler put a fan on it but no result.

  Maybe not enough power so i soldered 5v rail from psu directly to the pins  on the miner .

  But when i run more than 0B81 i get HW100% or bfg does not detect the miner but it shows it in device manager
