Compared to stock firmware this is nothing but like a silencer to a gun. Thats the only difference here folks. When you  can twist it to mine all x11 then let us know. Otherwise the dev fee is a free gift. Don't meant to be rude but when you have the source code. Its not off great difficulty to add or remove a few lines of code. Not knocking on this project, All i am saying is that when it comes to my build or my version of the antminer d3. Regular software from bitmanin and simple freq change does it here... Tested for two weeks. don't like to give my Hash power for free to the dev. Thanks, i am another who reverted.
