it shows examples to change for older and new antminers - well it looks like there's even newer that this thread refers to:
The thread show to change to this: and I don't have a '4e81' entry in my file - am I supposed to add the 4e81 entry?
From original overclocking thread....
package 'cgminer'
config 'asic-freq' 'default'
option 'freq_value' '4f81' #400M
option 'chip_freq' '400'
option 'timeout' '35'
#option 'freq_value' '4e81' #375M
#option 'chip_freq' '375'
#option 'timeout' '37'
#option 'freq_value' '4d81' #350M
#option 'chip_freq' '350'
#option 'timeout' '40'

however - this is in the file of my brand new antminer:

#option 'chip_freq' '325'
#option 'timeout' '40'
#option 'freq_value' '0b81' #300M
#option 'chip_freq' '300'
#option 'timeout' '45'
#option 'freq_value' '0981' #250M

#option 'timeout' '55'
#option 'freq_value' '0781' #200M
