okay, i have now started my 3 gekko compac f miner with the following command:
./cgminer -o stratum+tcp://de.kano.is:3333 -u cryptocygan.worker -p x --suggest-diff 442 --gekko-mine2 --gekko-tune2 60 --gekko-compacf-freq 555 --gekko-start-freq 555
i am now curious how long all 3 miners will run at this mhz
