Thanks for the nicehash support update , its working as it should now , overall diff from 9.7 is about 4% same settings for me ( 9.7 - 754 , 10.2 - 784 ) at 1167/1940 core/mem 880mv on xfx rx 470 4gb elpida , eth bios settings edit , maybe if I loosen timings will get more , monero do not like tight timings as much as speed. Power consumption is reduces in 10.2 about 25% ( 9.7 - 64w , 10.2- 51w ). My settings for 10.2 are -h 928 , I'm with 32 gigs of ram , 1gb virtual , do not see ram consumption increase more , no errors about virtual memory , will try with 4gb virtual memory whether have difference or not.
