Claymore - Possible bug.
With 10.2 Beta I am getting incorrect shares on my two Gigabyte 270 OC (Pitcairn) (non X)
I'm using the stock settings (-h 512) on non-overclocked cards. 9.7 did/does not give incorrect shares.
For me, this miner, for the old cards type 7850(1,2gb), 270(x), 280(x) is totally unusable, unfortunately. 15-30% less hash from clay9.7 version and too manny low diff share.
I spend 40 hours of my life trying to install it properly that at least I get at least the same hash rate, but , it's not worth it. 7850 with 1 GB of memory and 7950 remain on clay9.7, the rest on kachur miner
