I am using this (https://www.dropbox.com/s/z29x4n6ng510joi/bfgminer-npw-antminer.7z) in Win7x64 with the parameter "--set-device antminer:freq=0981" It starts up ok, finds the antminer but reports that
"AMU 0: Applying rule antminer:freq=0981: Unknown option:freq" and then starts hashing at the standard speed. Why? Supposedly overclocking is working? Am I doing something wrong?
Full start parameter is "bfgminer.exe -S antminer:all -o pooladdress:port -u XXX -p XXX --set-device antminer:freq=0981"
In this form it is working for me.
bfgminer.exe --set-device antminer:freq=0981 -o http://stratum.bitcoin.cz:3333 -O miner:password -S antminer:all
Make sure you have the latest version of antminer.7z
I think there have been 3 now.
