Hi,
I just try to update S320140811 with frequency management.
The frequency 225 is not part of the option (I do not know why?), it goes directly from 218.75 to 237,5.

Can someone tell me which file to edit to add the 225 frequency in choice?
THX.

Where did you get S320140811
Its available on Bitmains site. Upgrade with caution, it adds an advanced tab on miner configuration to set frequency, and does not include 225 as mentioned.
After flashing 1 ant it came back up at 100GH/s and took some serious fiddling to get back to 440GHs...
Also the asic-freq file is no longer used in the new firmware, no idea where you would add 225.
Would sure be nice if they opened up the source as required by the CGMiner license...
