Why with this bat i have only 400kh/s whit my r9 280x?
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
cgminer.exe --verbose --scrypt -o stratum+tcp://fry.minebig.com:3341 -u xxxxx -p xxxx --thread-concurrency 11200 -I 13 -g 2 -w 256 --gpu-engine 1080 --gpu-memclock 1500
What i must change?
Try removing after your password and add this: --lookup-gap 2 --thread-concurrency 8192 -g 2 -I 13 --auto-fan --gpu-fan 30-75 --temp-cutoff 90 --temp-overheat 85 --temp-target 75 --gpu-memclock 1500 --gpu-engine 0-1050 --gpu-powertune -20 --no-submit-stale
Thats what I use on my 280x Asus Matrix and I get about 750-780 khs
