Someone can help me?
I don’t use Linux myself so I’m not totally sure about this. But in the “good old days” Danbi made a modification to the sph-sgminer 4.1.0 and added support for the Diamond kernel. As far as I know this is the only miner that works with DMD and AMD cards (at least if you want to mine via stratum on a pool). I found the source code here: https://github.com/danbi/sph-sgminer. Don’t know if there are other versions available somewhere. Note that the kernel, diamond.cl, probably is an old slow one, so you should replace it with an optimized kernel instead for best results. Read the thread https://bitcointalksearch.org/topic/anngrsdmddgb-pallas-optimized-groestl-opencl-kernels-779598 by Pallas for more info about kernels and bins for the sph-sgminer. Hope this helps.
