I am certain I do not have the batch 1 and I am at 650, I was unable to use the firmware to change frequency so I used awesome miner.
Translation, and please feel free to correct me: You were unable to change frequency via the web interface, so you used awesome miner to change the frequency for you. Behind the scenes, awesomeminer modifies /config/cgminer.conf to set the frequency and restarts cgminer to make that frequency take effect.
I didn't say "only on batch1 hardware", I said "batch1 firmware".
anyway.
