Guys,

could you help me to decrease my rejct rate. I've got same settings for Smart and USDe. My ping to p2pool is around 50ms (taken.pl) and smart is: 14-15%, usde 7% rejects.

Here's my Cgminer config for 3x7950 (1,9 Mhash)(win 7, 4GB RAM, Sempron 145):

-Q 0 --expiry 10 --scan-time 5 -I 18 --thread-concurrency 22400,22400,22400 --gpu-threads 1 --lookup-gap 2 --worksize 256 --gpu-engine 1100,1100,1100 --gpu-memclock 1500,1500,1500 --gpu-powertune 20,20,20 --gpu-fan 68,65,65 --temp-cutoff 85,85,85

Just don't know, what could be improved.
