oh and here for the record the overclock settings. A noob (me) did some homework

ohh commandline for BFG is on the end:            antminer:clock=xValue          (no space between x and value)
and then after the x the value for the clock rate
1.6=0781
1.8=0881
2.0=0981
2.2=0A81

For CGMiner newer Version          --anu-freq Value                            (space after freq)
1.6=200
1.8=225
2.0=250
2.2=275
2.4=300
