Thank you, i thought there was a way, to upgrade the working system. I don't want to re flash sd card.
you can do an inplace upgrade of the controller.

Welp, upgrading my 821 finally. 
Edit for update.
Well so far no real noticeable change, hash is the same as it was at -2 but temps are lower and fan speed is reduced obviously.

I see above that the speed drops about 20-25% with the new firmware and the same voltage setting.
Can we really call this efficiency improvement?
I would expect less Watt while keeping the same speed.
It makes sense that less speed would mean less Watt.
It seems more like they used the voltage values of -3 or -4 for -2 now.

I like those numbers especially considering this isn't gear I'd have to order.
Did you happen to run any of them without the offset just to see what they draw for a baseline after upgrading?

No. All of them are at a colocation datacenter, and I instructed my service provider to run them with the offset from the get-go. I don't have remote access to the miners.

Each of my A841s are running — with a voltage level offset setting of -2 — at around 8.8 TH/s after the firmware updates, while drawing approximately 732.5 W. This translates to roughly 82.9 W per TH/s.
My 841 units dropped from 13.7 TH/s to 9.2 TH/s and my 821 units from 11.6 TH/s to 9 TH/s. These are all on the same controller and haven't tried running them on their own. I upgraded MM firmware separately. Voltage level offset set to 0. Claimed .085 J/GH. I don't have meter but that should put them around 750-800 watts. I swapped out some larger PSUs for 1200w HP. Two 841 on this firmware seems like it would be similar to a single 921.
Canaan has released new OpenWrt and MM firmware for the A821, A841, and A851. They claim in an email (the same email that announced their flash sale) that the new firmware improves efficiency to up to 85 W per TH/s.

There is no changelog for the OpenWrt firmware at the time of writing.
The changelog for the MM firmware simply states "support for low power."

Anyone report any changes to hashrate w/ the new firmware? Despite Bitmain using "Low Power Mode" as code for ASICBoost, Canaan's latest firmware is just voltage optimizations, correct?
You'll have to flash the relevant OpenWrt image to your Controller's SD card. These instructions should help get you going. (Etcher is a good alternative to Win32 Disk Imager if you're not using Windows.)

Hello, i upgrade MM firmware, plz help, how i can upgrade OpenWrt?

Is there an easy way to know what model Pi the canaan controler I have is? I didn't get mine recently and noticed they list the Pi3 currently.
Yes. Log in to your Controller and you'll find its hardware model in the "Model" field under the "System" heading of the "Status" page (which is the first page you'll see when you log in).

That's promising. I'll have to give it a go for the 841 it would be interesting to see if this can be combined with the previously found efficiency settings playing with the voltage.

and last but not least a bad auc is possible
but in your case 741 can not and will not run 821
but in your case 741 can not and will not run 821
If running on a separate controller with 821 firmware doesn't work, you may have a bad AUC3 cable. My 821 came with a bad cable. Converter would light blue/green, but miner would stay in idle status.
Just bought a Avalon 821 and it's not linking up with my other avalon 741's? Even tried it on it's own uac 3. Anyone know the reason? Goes from blue to green back to blue?
Um, perhaps read the 1st few pages of this thread?The A8xx uses different controller firmware than the A7xx series and the 2 versions are not compatible...
A821 controller image is here: https://canaan.io/downloads/software/avalon821/openwrt/20180305 from there pick which flavor of RasPi you are using and burn the image to the controller sd card.
Please setup the A821 with a own separate Raspberry Pi controller, AUC3 Converter and AUC3 Cable.
And install the latest A821 OpenWrt firmware.
See my review/guide for more.
