Hey everyone, so first off im still fairly new to mining and this forum. I have been running a few usb block erupters for a while; I thought i would step it up and get an bitmain antminer u3. I've successfully got it to start hashing in bitmains cgminer for the u3 using different frequencies and voltages. So far every combo for the command: "cgminer.exe --bmsc-options 115200:0.55 –o stratum+tcp://stratum.bitcoin.cz:3333 -u batmansmokes.worker2 --bmsc-voltage 0800 --bmsc-freq 0250" with different timout (115200:0.55), voltage and freq and i cannot get it to hash past 6 or 7 gh/s. The advertised is 62-63gh/s. I've got it plugged into a powered usb 3.0 hub with its own powersupply plugged into the wall. I used this setup tut (
