Mods: If this should be moved to the HW thread I apologize but I wanted to see responses from a small sample of my mining brothers and sisters here.
I do not normally recommend updating firmware and am not recommending anyone do so at this time. There could be all sorts of problems such as bricking the miner.
My experience with my recent avalon 6 update has been positive.
I took some screenshots of the miner GUI and poolside user shift performance for that miner. Not a great enough time has passed to say this is / was a good move.
Initially it appears I have made good gains in hashrate.
I only applied the MM update for troubleshooting.
My incoming voltage is over 12. Using the awesome adjustable 4k setup with the s9.
The hmi used to show 12, - 12.2 but that changed after an RPI update and I have not applied the most recent RPI update.
The hmi now shows between 11.8 and 12.1
I will post numbers when I confirm a consistent increase over additional time.

For all Avalon A6 owner's out there, I have updated my power supplies with this 2400watt Kits from Parallel, I've seen an hashing rate increase of 200mhs +- 30mhz per unit. The kit can power two A6 and two A7. http://www.parallelminer.com/product/delta-2400watt-platinum-94-efficiency-power-supply-208v240v/
12.5 volts is high volts it is over volts for the a6. I know I killed an Avalon 6 board with higher volts.
