What kind of temps are your dr3 chips running at and at how much wall power?
Mine temps are 88C, 85C, and 83C at 100% fan and my meter is telling me it's pulling 1570W. Miner says it's between 7.8 and 7.9 Th/s.
At least I don't have any chain errors and my HW errors are relatively low (less than 50 after 10min).
what frequencies are available by default?
Can you set a frequency other than the included ones via the browser/inspect or editing /config/cgminer.comf?
If so, I can move on, if not, I want get get the firmware and open it up.

Default frequency is set to 410M. Looks like normal frequencies available to select up to 450M are available. I tried SSH into the miner with user/pass as root/root but denied. I'm not really comfortable with setting new frequencies yet as I'm still gauging default characteristics, but would be happy to get you firmware image if you know of a way.
