Have you created a ".sh" file to run it with your specific frequency in the command line?

If you run the standard one it will default to stock freq.


I dont think so  i just start cgminer with this command 

cd ~/git/vthoang/cgminer/./cgminer -o stratum+tcp://sha256.mining-dutch.nl:9996 -u / -p  / --suggest-diff 10 --gekko-2pac-freq 200

How do i do that
