Awesome! Thank you for sharing freely and openly.

.... and for the record, any one responding to my post and providing feedback, did it of their own volition. While that was 'good marketing', it was not driven by me and was completely organic.
.... and as far as comments about donations, you can see for yourself by checking the addresses for donation. The only funds sent to those were funds I mined myself during testing, and funds someone sent before talking to me asking to get the full version..

I've updated my post pointing people to you. Enjoy!

I'll stop working on per-hashboard-frequency management that would have worked on every single cgminer based miner Bitmain has released.

To do it, just add 2 more segments to cgminer, code up the frequency management reading functions back from cgminer.conf, then go into the main loop that handles frequency setting for the hashboards, jump the current function into your code, set up the same registers, and jump back into the function that actually sets the board frequencies.
Second, modify cgminer to support updating the frequencies across the boards by not having it restart. To do this, hook into bitmain_ZCASH_reinit_chain, but don't step on the functionility int he check_miner_status() function.

Also, please update the image to support auto-tuning of the frequencies once you have this done so the end users do not have to worry about the clocking manually. Many do not know how to SSH/etc.

Back to my day job!
