Very important... we modified all the remaining units to support the voltage scaling feature. This means that you can adjust the supply voltage for the Bitfury chip by software.
A higher voltage level means the Bitfury chip is probably hashing faster.
A lower voltage level means the Bitfury chip is probably hashing slower but is more stable with USB 2.0 ports.
The feature is available from bfgminer:
Press M, select the device with the cursor keys and press V to adjust the supply voltage. You can enter the voltage in the range of 800mV and 950mV. But you will need some active cooling fan if you increase the supply voltage.
Especially at the 60 euro shipping!
