I'm trying Mining Field (USA) and Radeon Crimson 15.12, with sgminer from "https://github.com/sgminer-dev/sgminer". And I think they already banned my IP for so much rejects
For what its worth, if you create the optimized bin files using driver package 14.7 you can upgrade to 15.12 and get the same hash rate. I have upgraded to 15.7 and have not seen a performance drop off using the 14.7 bin files. This is true for Ubuntu as well as windows. I do not recall if I tried optimizing the bins with 15.x. But as Utah says only sgminer 4.1 works with DMD. Its unfortunate but not unlike some other coins with specialized versions of miners.
Yes, .bin files are Compiled by the driver! keep .bin's and u should be fine with later versions of driver... but 14.7 generates the best fastest .bin for DMD Other than assembly code for 280x which is also covered in pallas thread
Sorry but thread does not allow attachin files or I could provide a bin, perhaps Creeper will make one available via mega ... I just don't give a **** after all the non-listening
