have 6 * Hd7850 with 25% incorrect shares and 2 R9 270 with 10% incorrect shares.
All cards are non overclocked and working ok with 9.7
A solution would be wonderfull
Drop me a PM if you ever want to get rid of your 7850s

hey, what about with your hashrates with the r9 270 hashrate in both version? without overclock of course
