im just starting out with this so i just put this in the console
cgminer.. -o stratum+tcp://pool... -u ... -p x --suggest-diff 32 --gekko-2pac-freq 150
(with the correct pool details etc)

EDIT:
fixed it, thanks for the direction

steps,
show hidden files
open .cgminer > config.conf (text editor)
change the frequency in that file > save

thanks for the fast response
im guessing it must be the config file. any ideas how to change that?

hello
ive tried searching this massive thread for an answer but didnt find one.

im running a 2pac using a raspberry pi and a powered hub with the build of cgminer linked in the first post.
i am unable to increase the frequency above 100mhz, the hashrate hangs around 10-14ghs

gekko-2pac-freq doesnt seem to make any difference, tried at 100 up to 300
i turned the voltage pot clockwise 1/8 and no difference

anyone have any ideas what i am missing here?
ive seen other people with the frequency even at 300 on the cgminer log, how do they do it?

thanks
