My Gigabyte R9 290X is getting 863Kh/s with WU:780/m and 79C
setx GPU_MAX_ALLOC_PERCENT 100
cgminer --scrypt -o stratum+tcp://scrypt.megamultipool.com:80 -u user.user -p password --intensity 20 -g 1 -w 256 --lookup-gap 2 --thread-concurrency 24550 --gpu-engine 920 --auto-fan --gpu-memclock 1500 --gpu-powertune 20 --temp-target 80 --temp-cutoff 95 --temp-overheat 92
Why do you have GPU engine so low? And stop using intensity - switch to xintensity and you will see several percent hashrate increase.
Is it possible to call xintensity inline in a .bat? I'm running a 280x and a 290 on the same rig, and if I completely remove intensity from the config, things start to crawl really slow :-/
