for old R9 290 cards still work better than Claymore 11.1.
I work with 1.5 version because for version 1.6.0 and 1.6.1 windows 8.1 and 10 freeze and cant restart. Last version miner work with more sol but often freeze is not offer to change to 1.6.x
I work in 1.6.1 very stable.(seven GPU) don't freese any cards.
