Hi, doktor83
I have Rx550 card gigabyte and Asus. On 1.6.8 version of miner i'm using "fragments" : 338033747 and about 520 H/s on v7 or stellite.
But on version 1.7.2 if i set "fragments" : 33803374 then miner set 1. And perfomance about 500 H/s.
If "fragments" : 9997 then speed 480 H/s. If "fragments" : 9998 then speed 500 H/s.
Is it possible to return old behaviour, and i can set "fragments" : 33803374 ?
