Topic: Avalon 8 official specs released - page 14. (Read 30297 times)

(1) they're not shipping yet
(2) there is no official price on them yet.
(3) NOBODY is "snatching up these 821s" because they're NOT AVAILABLE YET.


 Their *SPECULATED* price is triple the 741 based on the price spike Bitcoin had a couple weeks back and the resulting Bitmain S9 pricing on THEIR last batch.

 If Bitcoin stays around it's current price, the 821 likely will end up selling close to $2000.

 They can get away with higher pricing than the S9 even when the performance is lower due to the far lower FAILURE rate they have compared to the S9.

At over $3000 per unit for the 821s with only 11TH, how does anyone breakeven on this investment unless they have free power? The calculators say it would take over 1 year for me to break even assuming difficulty never rises from current levels. So why is everyone snatching up these 821s at triple the price of the 741s? Are they all hoping BTC is going to jump to the moon again like last year?

 Nice typo (on Avalon's part).

 8-O

Because I didnt pay that much *shrugs*

No price for the 841s?  Seems 821's will still be shipping in March so there are some considerations

@fanatic26

I can confirm that it is a legit message from Steven.

It's a typo. It should say that the A841 performance should range around 13TH and 1.2 kW.

He received it from the manufacturer, as did I.  Why do you feel it's not true?

Not sure where you got your data but I wouldnt be sharing that information since it is not true.

consider yourself lucky - it wasn't like everyone that wanted them in Nov could get them and many people got back into mining only when the weather got so cold that they dusted off their old ones for heat... then it was a mad dash for the rest of the stock

821 price predicition for distributors

For 821  you can consider that the price could be anywhere between 3000 and 4000  per machine.

Avalon  841 release:

The 841  should start shipping in the March April time frame. Performance should range around 13TH and 12 Watts.

In november i bought a nice 741 for 900$ they really went crazy with the prices, i dont know who the heck is buying these 821. ROI is AWFUL 3800$ for 11th/s. I dont know what is ppl thinking, bitcoin is barely over 11k difficulty is A LOT harder since november and they wanna charge 3 times more for the same amount of hash power? A 741 at 900$ was 128$ per 1 TH/S a 820 at 3800$ is 345 per 1TH/s all while 1 th/s pays less now than in november

Bitmain changed their prices but it wasnt so crazy from 1400 to 2300

Thanks for clarifications @frodocooper

Thanks for the rundown..  as far as grabbing the new versions, shouldn't there be a zip file instead of all the files on the repository? 

Is there an easy way of downloading them and putting them on the card?   It seemed I only was able to navigate through the path directories and download one by one

More accurately, you would be flashing a Canaan-customized OpenWrt image to the SD card. This OpenWrt software is the "Controller Firmware" that runs on the Controller/Pi, and it contains everything needed to run AvalonMiners. LuCI is a package within OpenWrt that provides you with the web user interface.


Yes. This is because all Controller software before version 20171216 does not have any code that recognizes the A8 series.


It should be possible, in theory. This is because the Controller software for the A821 (version 20171216 and later) still contains code that recognizes the earlier AvalonMiner models.

However, I'm not sure whether the Controller software for the A821 is fully backward-compatible in practice — i.e., I'm not sure whether the A8s can co-exist peacefully alongside earlier models on the same Controller. This is because the A821 seems to be using new A8-specific cgminer parameters — e.g., voltage_offset has been changed to voltage_level_offset in cgminer/files/cgminer.avalon8.config, and this change is reflected in cgminer/files/cgminer.avalon8.init.

I'm therefore not sure whether or how the "CGMiner Configuration" page in OpenWrt would be able to distinguish between the A6- and A7-specific voltage_offset setting and the A8-specific voltage_level_offset setting, and whether or how the "CGMiner Configuration" page would be able to distinguish between other changes that I may have missed. For example, this may break the "Voltage Offset" option in the "CGMiner Configuration" page when A8s are mixed with earlier AvalonMiner models on the same Controller.

It may therefore be better at this point to run your A8s on a separate Controller/Pi, at least until Canaan sheds more light on this.


Yes. Never update the MM firmware when having a mix of different AvalonMiner models on the same Controller. This seems to be even more crucial when having the A8s on the same Controller, as the A8s seem to be using a different flash layout.

Sorry to beat a dead horse, so to say. I'm not technically savy but I like to learn so let me know if I get this correct and definitely point out anything wrong.


Thanks for the information, I do appreciate it.

So in the example of setting up a controller off a Rasp PI, I would load the suggested Firmware following the instructions on the Canaan site.

Is the "SOFTWARE which is based on OpenWRT & LUCI" just part of this package that I would be flashing to the SD card? I get hung up on the terms


Thanks for the links, and clarification.

So if I get this right, anyone with a version of the Software for their controller older than the one you point out, would need to reflash the SD card with new version marked as "Controller Firmware" for the 821.

In doing this in theory anyone with Avalon 6, 721, 741, and 821 could run off the same controller? Or at least they could go with 741's and 821's

If they do run a mix on this controller down the road if they upgrade MM firmware for Miners they just have to diconnect say the 821's to update the 741's and vice versa.

thank you for the clarification

Yes. You may find the software and firmware for the A821 here.


No, all Controller (Raspberry Pi) software before version 20171216 are not compatible with the A8 series. Controller (Raspberry Pi) support for the A8s only began with the addition of commit 591b6a9 and the ones after it.

Firmware has NOTHING to do with the controllers. Firmware resides only inside the miners themselves. The 721/741/821 all run the same controller SOFTWARE which is based on OpenWRT & LUCI.

The current RPi software works for both the A6 and the A7, chances are it will work for the A8 as well. The big difference will be the internal mm firmware for the miners daughter card, that is what actually controls the boards.

Is the 821 firmware available for the controllers yet?   I got a blokforge 741 controller but now getting an Avalon 821 miner instead so mineaswell get ready
