For now, you can try nanominer or gminer. Some cards are having higher number of stale shares with nanominer like 15%, while with gminer they are around 2.5%. For some reason gminer is not working on smos (althuogh i didn't test the newest version of smos), but on hiveos it is working well. Not so well as Claymore, but good enough. The cards that are undervolted -150mV used to work and normal speeds with 30 Mh with Claymore, while on the other miners they crash and I need to underclock them to mine with 28.5 Mh. I have no information of memory timings for these cards, only read that it is possible to make these cards run with 31+ Mh. The cards that are undervolted -200mV didn't work with Claymore either. So now all of them are set to the clocks of power stage 6 instead of 7. If someone knows better how to solve these problems, please let me know.
