Running AntMiner U1 USB ASIC with the Latest Cgminer 3.12.3

The latest version of cgminer 3.12.3 has built-in support for the Bitmain AntMiner U1 USB ASIC devices, so there is no need to use the older modified version of cgminer 3.8.5 that Bitmain provides for use with their USB Bitcoin miners. The support in the new cgminer 3.12.3 offers much easier use and more stable hasrate, the HW error rate also seems a bit lower compared to the results with the older version of cgminer. So we would advice to download and use the new cgminer 3.12.3 along with your AntMiner U1 devices and below you can find information on how to run it:

cgminer.exe -o stratum+tcp://us-west.multipool.us:7777 -u yourworker.1 -p password --icarus-timing=short --anu-freq 200

The above example will run the AntMiner U1 at 200 MHz and should produce a hasrate of about 1.6GH/s, by increasing the frequency number to 250 for example you can get 2 GH/s hashrate and 275 should get you 2.2 GH/s. Do have in mind that overclocking the AntMiner U1 should be done only after you add a cooling fan to improve the operating temperature of the device. We’ve already measured the operating temperature of the AntMiner U1 at 1.6 GH/s and they do get quite hot even at “stock” frequency. Don’t forget to change the pol and worker/password with your own settings!

If you have Bitmain AntMiner U1 USB sticks for Bitcoin (BTC) mining you would need to use a special version of cgminer miner software that is compiled to support these BTC ASIC devices. Below you will find cgminer 3.8.5 compiled for Windows that has support for the AntMiner U1 USB ASIC miners along with example BAT files to run the USB ASIC at “stock” frequency for 1.6 GH/s, along with settings for running the device at 1.8 GH/s, 2.0 GH/s and 2.2 GH/s. Just make sure that if you overclock the AntMiner U1 for higher hashrate to ensure that the device is properly cooled – you need to provide additional fan blowing on the device to cool it down when it is overclocked. Do not, and we really mean that you should not overclock the AntMiner U1 without additional cooling or there is risk of damaging the device from the heat generated by it during mining!
