1) path to .exe -o http:api.bitcoin.cz:8332 -USERNAME -p PASSWORD
2) cgminer -o http:api.bitcoin.cz:8332 -USERNAME -p PASSWORD
cgminer.exe -o api.bitcoin.cz:8332 -u USERNAME -p PASSWORD
I've tried that too and it doesn't work. When i try to use guiminer then it's fine but i got ~250Mh/s instead of ~355Mh/s with cgminer :/
