I get around 20% stales. Is that normal?
What settings are you using and on what card?
settings:
cgminer.exe --scrypt -o stratum+tcp://pool1.eu.multipool.us:7777 -u user.1 -p x --thread-concurrency 24000 -I 20,20,14 --gpu-memclock 1500,1500,1475 --gpu-engine 1050 -w 256 --lookup-gap 2 -g 1
cards:
3 x 7950
Try this.. move your cgminer.conf file out of your directory its in. Then delete all the .bin files, then run from a cgminer shortcut this to see correct TC.
cgminer.exe --scrypt -o stratum+tcp://pool1.eu.multipool.us:7777 -u user.1 -p x -I 13,13,13 --gpu-memclock 1500,1500,1475 --gpu-engine 1050 --auto-fan --no-submit-stale
After you run it.. let it start mining. Ignore hashrate, its on I 13 for a reason here. After you see it mining and successfully sending shares, save a new config file (S,W,Enter). Then see the new .bin's with correct TC for the Tahiti's (7950s). Use this tc number from the bin to set it in your .conf file. Try running at I-19 also, may be more efficient on fast coins. Also, you prob need to tweak your GPU core and Mem some more. I have same cards and I'm close to 700kh/s at 1150/1650 no errors, few stales.
GL!
