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!

Thanks

No need to play with it, as it is only used for the proper calculation and reporting of the hashrate of the miner.
