Personally, I use BFGMiner, as I find it more forgiving. To each his/her own, however. My current batch is using the following:
bfgminer --scrypt -S gridseed:all --set-device gridseed:clock=838 -o stratum+tcp://gmc.suprnova.cc:7351/#skipcbcheck -u USERNAME -p PASSWORD
As you can see, I am slightly overclocking. Normal clock is 800. I find 838 works better (less hardware errors) than 850. Good luck.
