THANKS dear Protagonus ... but i can mine just 3 coin in 1 hour and 96 coin in 24 hour
my config is :
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
ultracoinminer -o stratum+tcp://ultra.leetpools.com:3333 -u xxx -p xxx --scrypt-jane --sj-nfmin 4 --sj-nfmax 30 --sj-time 1388361600 -w 64 -g 1 -I 18 --thread-concurrency 42000 --no-submit-stale --lookup-gap 3 --expiry 10 --scan-time 1 --queue 0
Hmm anyone mining on 290/290x without HW errors?

--intensity 18 --thread-concurrency 56320 --gpu-threads 1 --lookup-gap 2 --worksize 64
gives me 174 kH/s for a R9 290, 1035/1250, 8gB w7 rig, catalyst 13.11 beta

Try these setting above maybe? I do not use the 290. I use the 7950. I think this was the highest speed posted for 290's
