Hmmm for some reason I'm not able to get over 17Kh/s with my cards. Can someone give me some reference configs I can put into a .bat file and try for the 280x (sapphires). I tried a bunch of combinations with the guide, could it have anything todo with my x32 OS or my 2GB of system RAM?
I'm able to get my r9 280x cards up to about 21.7 which is pathetic...

any ideas would be appreciated - I thought I could do ok with the this coin but I'm better off mining straight scrypt
I wish I could help you out with your situation. I had problems with cgminer. I went to YaCoin miner. I have 2 R9 290x cards on 32 gig ram Xidax computer with Windows 7.
I had problems mining the coin until I downloaded latest YaCoinminer from thirtybird. Search thirtybird in the bitcoin forum search window (inside this thread) and you will find his latest download version. I'm currently using Yacminer 3.5.0 - My settings are:
yacminer --scrypt-chacha --worksize 128 -g 1 --lookup-gap 4 --buffer-size 3532 -R 10496 --auto-gpu --auto-fan -o stratum+tcp://stratum.ultracoinpool.info:3333 -u craigclaussen.Ultminer -p Mineroneniner --nfmin 4 --nfmax 30 --starttime 1388361600
pause
I raised my lookup-gap on purpose. It just makes my system perform better and with less heat while I mine and multi task on the internet. I'm getting around 57 k/hs per card. It's kind of funny, as both cards seem to maximize K/hs better if I have more applications on my computer running at the same time - weird??
Either way, I have no HW and my reject average is just less than 1%.
Hope this helps! And sorry if it doesn't. So many different configurations to create settings for.
