Sometimes it's best to pass along other firmware modifications that have been developed longer than the time I have spent on this project.
Here is a flashable firmware with some pretty solid specs that beats all the current competition. I have partnered up with another brand to help release their firmware for the US markets. That is until the team I am working with finishes the project we are working on but that is hush for now
There is a dev fee on this firmware but it is less than what you will find on asicseer and the competitors. Here are the results
475 - 8.0 - 10 TH/s - 750 watt
550 - 8.2 - 11,6 ths - 950 watt
(78 waтт / THs)
631 - 8.3 - 13,5 ths - 1100 watt
(81 waтт / THs)
700 - 8.6 - 14,9 ths - 1300 watt
(85 waтт / THs)
750 - 8.7 - 16.1 ths - 1450 watt
(90 waтт / THs)
As you can see this allows current S9's to still be profitable at the current difficulty for those with 7 cent power and cheaper.
To upgrade just flash this firmware through the console. This has Asic Boost, LPM, Auto Tune. It has triggers to restart if hashrates fall if more then 5 xxx on the chain. Min Frequency is 400mhz. I suggest setting Frequency for auto tune and clicking save. Then for the next 30minutes to 1 hour expect the machine to reboot as it tunes.

I am running the BixBit firmware (with Dev Fee.......) 0n my T9+. A few things I would change but generally a very solid bit of code. Am pretty certain that the per chip Frequency setting, at least in the BixBit code, works as the effect on Hash Rate & Efficiency track very well.
Have ditched using the Autotune and have spent some Hours doing all the changes manually. The T9+ is now running at a steady 10.3TH consuming 930W at the wall, which is a none too shabby 0.09 J/GH :-)

Yes as is the firmware I link in my main post Auto Tune is great. But you can always just hard set the values and be done.
