Canaan has released new OpenWrt and MM firmware for the 821, 841, and 851.

OpenWrt

AvalonMiner 821: https://canaan.io/downloads/software/avalon821/openwrt/20181223/
AvalonMiner 841: https://canaan.io/downloads/software/avalon841/openwrt/20181223/
AvalonMiner 851: https://canaan.io/downloads/software/avalon851/openwrt/20181223/

MM

AvalonMiner 821: https://canaan.io/downloads/software/avalon821/mm/2018-12-22/
AvalonMiner 841: https://canaan.io/downloads/software/avalon841/mm/2018-12-22/
AvalonMiner 851: https://canaan.io/downloads/software/avalon851/mm/2018-12-22/

There are no published changelogs for all three OpenWrt firmware releases at the time of writing.

The changelogs for all three MM firmware releases read:

Code:

Version 8211812-d33ea90

* Support low power, modify volt adjusting method and certain ss params.

Version 8411812-d33ea90

* Support low power, modify volt adjusting method and certain ss params.

Version 8511812-e19ca70

* Support low power, modify volt adjusting method and certain ss params.

Interestingly, version 20181223 is treated as a new distinct branch in Canaan's GitHub repositories. Canaan calls it avalon8-lp here, here, and here.

Notable changes in version 20181223 include:

changing the default voltage level to -8,
changing the default target temperature to 64°C, and
changing the default minimum fan speed percentage to 3%.

you need to roll back the controller and the MM firmware.

only doing one of them doesn't work as I mentioned in an earlier post.

just do the "upgrade" by selecting the previous version to downgrade.

Yes if you roll back to the original firmware your miners were running you should be able to get the same results as before.

Yku may also be able to play around with the voltage and and voltage level to increase the hashrate with the current firmware.

I'd need to play around with my machine this weekend to confirm.

Are you saying my problem would be solved if after updating the miners I was supposed to update the controller?
Both have been real stable running for weeks but only get each
Controller Version: Avalon Firmware for avalon8 - 20181123
9380.17
9251.03

So How do I get my 13TH back? Rollback the miner and leave the controller the same as thats all I did before was update miners.

[...] To achieve the desired efficiency do you have to have the update installed for both the Miner and the Controller, or do you achieve results by just updating for the Miner?

I'd say both. The Controller's cgminer would need to be updated to include the new high-efficiency mode and the MM firmware would need to be updated to understand what that mode means and how to execute it.

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.

Quote from: mgoz on December 01, 2018, 12:00:04 AM

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.

It just dawned on me that for the moment, with these upgrades available the 841 is pretty much equal with the 921 right now for Canaan's most competitive hardware.

I'd like to reflect that in the Current List of Competitive Hardware - December 2018. Just want to make sure the details seem clear where I link to. To achieve the desired efficiency do you have to have the update installed for both the Miner and the Controller, or do you achieve results by just updating for the Miner?

I estimate saving 360 kWh of energy a month per miner on low power firmware. Extra hash rate on old firmware isn't worth the 15% increase in energy use for me and would only generate around 0.006 BTC/month per miner. Not even profitable unless rate is $0.06 kWh or less.

yeah, that's probably it, minefarmbuy.

I only use the pretty view to monitor speeds on new firmwares as that constant updating doesn't time out the session.

too bad it shows the wrong temperature there and not the most important one.

I wonder if their still in the "vanity" UI? Click "advanced version" to access more controls.

I told you before how to upgrade a working system.

just point to the sd card image from in the controller web interface and it will update the system and keep the current settings if you leave that checkbox ticked.

you don't need to flash it with you pc.

the openwrt-brcm2708-bcm2710-rpi-3-ext4-sdcard one is the controller/OS.

make sure you have the current and previous one handy as the new speed might not be what you want.

openwrt-brcm2708-bcm2710-rpi-3-ext4-sdcard this is sd card image, i want to upgrade working system without flash image to sd card.

Make sure you downloaded from the 20181128 (OpenWrt) and 2018-11-26 (MM) directories. The directories labeled latest have not been updated and therefore still contain OpenWrt and MM firmware from March 2018.

I followed the links you gave earlier in the thread. I'm not sure with the performance I'm getting if I'll change anything yet before I get a read on the draw. On another pool I get small drop in hash average about 19th/s and on ck's 21 th/s, at "0".

Same here the update reduce miners from 13.6 down to 10-11TB

I imagine I did the incorrect firmware?

FC's hashes are consistent with what you were receiving.

I speculate I'm using less power with a hash rate decrease but its just not as substantial. I updated the mm then flashed the controller.

I did a roll back to 20180306 & 20180305 and I'm back at 13TH.

I tried rolling back...

only the MM
only the controller firmware
keep the latest controller with previous MM

but none of the above worked to get it faster again.

both need to be put back to the previous version.

I tested on a 841 maybe they messed up something altho I doubt it because 13*0.7=9 and that's the max I got beside a burst of 12.5TH once at the start.

I wonder if I have the right firmware then. I up clocked to "0" before calling it day about 9 hours ago and they're hashing about 10th/s each on the 821's I have.

openwrt-brcm2708-bcm2710-rpi-3-ext4-sdcard

and

MM821.mcs

is what I flashed last night.

I did the upgrade on 1 machine.

with the -2 setting it dropped from a constant 13.xxTH to 8.3TH. (running for 30 minutes now)

in/out temps are the same as usual but the fan is at 20% instead of 90+%.

I don't know if it is adding 0.1TH every minute now instead of full speed from the start.
I'll keep an eye on it and update this post if it changes a lot.

Edit(s):

0 : 9TH 20% fan (--avalon8-voltage-level-offset 0 --avalon8-temp 75) weird one here... started at 13.5TH for half a minute then dropping to 9TH and stuck there.
-1 : 8.8TH 20% fan (--avalon8-voltage-level-offset -1 --avalon8-temp 75)
-2 : 8.3TH 20% fan (--avalon8-voltage-level-offset -2 --avalon8-temp 75) was 13TH before the update

Oh boy... I just spotted the firmware post on Canaan's site...

Quote from: https://canaan.io/avalonminer-8-series-high-efficiency-firmware-released/

We have just released High-Efficiency Firmware for AvalonMiner 8 series. The High-Efficiency firmware can reduce 20% – 30% of power consumption, but it will also reduce about 30% of Hashrate.

no wonder it barely goes above 9TH. Sad
