Avalon 8 official specs released

[gvb]

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 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.

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.

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?

[...] 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.

[notabeliever]

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.

[Steamtyme]

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.

[gvb]

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.

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%.

this will be good if and when they drop the a921.  I would like to buy a second one

[minefarmbuy]

Yea, your thread has been pretty a good read. Hope to upgrade while the flash sale is rolling.

I had a pretty cool find while browsing through the internet.
Eastshore has written a short review for the Mining Warmer, also known as A851H.

[Steamtyme]

It's a christmas miracle.

A hardware manufacturer speculates a product and it actually get developed and delivered, or at least a machine was sent out for a 3rd party review.

Can't celebrate to much as Canaan tends to meet or exceed expectations while also delivering on almost everything they have speculated on.

I really like this machine actually. I wonder if there is a setting or if playing around with the voltage configurations can get it closer to the advertised specs, if so I could run 3 of these in place of my 4 741's.

That would be about a 13TH/S increase with ~200W power savings. The price would be a huge factor though considering I already have the 741's and a rough enclosure for them.

[HagssFIN]

As it is a 8 series miner, maybe there will be a low power firmware available for this model as well.

[leowonderful]

This new Avalon miner could sell pretty well and replace the now-aging R4 units Bitmain made (though this thing likely needs 220v+ to run) and run nearly 2x faster than the R4s, though the efficiency on both the R4 and this heater seems to essentially be the same. I wonder what the dimensions for this miner are compared to the R4s- I assume this thing's larger, but it's still a quiet miner according to the Eastshore review. Seems like this thing relies on a liquid cooling system judging by the review stating that purified (I assume distilled) water needs to be added in for it to run. I also wonder how undervolting might fare on these units.

anybody test this?

[minefarmbuy]

I ordered some equipment to monitor power draw. Hoping to update when some things slow down.

[frodocooper]

It appears that Canaan fixed the previously non-functioning Voltage Level Offset drop-down menu on October 6, 2018.

The Voltage Level Offset drop-down menu in versions 20181128, 20181223, and later should therefore work properly now. It should no longer be necessary to add the --avalon8-voltage-level-offset command-line option in the More Options field to change the voltage level offset setting.

To check whether the Voltage Level Offset drop-down menu is working, navigate to the Processes page (under Status) and scroll to the bottom. The --avalon8-voltage-level-offset option in the row that is displaying the cgminer process should reflect the selected value from the Voltage Level Offset drop-down menu.

[HagssFIN]

Great! Maybe they remembered me mentioning about that in my review.

[minefarmbuy]

Finally got to my draw check on the two 821's I updated. Together hashing 20TH at 1970w on an apw5.

Yes I spoke directly to the Canaan devs about it on the 3rd of October after having problems with an A851 and A921 they sent me and after I identified what the problem was.
