Hello
I have created .bin files to boost your hashrate.
These .bin files were made on 14.6 drivers and are meant for 14.4 systems.
R9 280X 1150/1500 1.200mV
My examples were made with following config
sgminer.exe --algorithm bitblock -o stratumserver -u xxx -p xxx -I 18 -w 128--thread-concurrency 8192 --lookup-gap 2 -g 2 --gpu-engine 1150 --gpu-memclock 1500 --no-submit-stale --no-pool-disable --hamsi-expand-big 1
--> IT IS IMPORTANT TO ADD "hamsi-expand-big : 1" to your config or "--hamsi-expand-big 1" to your .bat for maximum hashrate.
Standard 14.4 .bin gives 2.12mh/s
14.6 hamsi-expand-big 1 (worksize 256) .bin gives 2.48mh/s

Hope this helps your hashrate improve, cheers.
