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

Why get rid of them......these old buddies (hd 7850 /r9 270) are my working animals

(Started with X11-coins)
and earned nearly 100 ETH
My old 7790 are my 'retired worker' but still impressive! (started with scrypt-coins)
and my RX 460 passive cooling are my current workers
Just laying it in there bro, I know they're great work horses that's why I want them
Bought 4 off ebay really cheap want to build a rig with them.
