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!
