haha, we were hoping to get a github response since june, looks like you just posted on our issue.

Just created a thread in the "mining software" section of bitcointalk. Perhaps you could join in there for AMS stuff? (presuming the mods don't purge my post for some reason)

It would be good if they posted that on their website. Suggest mentioning that to Lily if you get the chance.

ps. If you happen to be talking to her, please ask her to have someone address the issues posted on the Avalon Management System github forum.

Canaan clarified a week or so ago, I think I posted about it here or another thread. Lily is our main contact.

6 month comprehensive warranty, 2 year limited. Now I sound like an insurance agent.

Canaan's 2 year limited warranty applies to the 921.

From https://canaan.io/product/avalonminer-921/

"AvalonMiner 921 includes a 180-day warranty, starting from the date goods are received. Canaan guarantees a 180 days warranty from the first date you receive the goods. We promise to replace defective or faulty parts with new parts, but mining earnings will not be compensated. Buyers pay inbound shipping and we will pay the return shipping. Please note that we are not responsible for any loss caused by customs delays, losses or charges."

Sounds like 6 months to me...

921? No philip we don't stock. We have a group buy up if people want to join. Though the 20 units MOQ isn't so bad but well out of my capabilities. I put in for one myself but looks like it may take a while to fill as demand is sparce.

With new tariffs international buyers are able to get cheaper units at least regarding Canaan. I'd be happy to plug a reseller but they upset me in another thread. I probably just need my coffee.

Noticed that the 2 year warranty is now a 6 month warranty...

Did not notice that actually. Upsetting. We will see. I plan to be going with the most efficient for this next season. I have my eyes set on 2 or 3 companies so we will see.

I really like Canaan and heavily support their miners because of the reliability and warranty they offer. This miner however, I sadly will not be getting. Very big disappointment, I can't believe they would even release a miner with these specs when they boasted a 30th miner with much much less watt per th. Guess wait for the 941..

Canaan uses TSMC.

I can confirm that.

Anyone know what fab Canaan uses for their 7nm chips? I wonder if it's a bad 7nm process that's preventing them from gaining higher efficiency/hashrate.

Agreed, feel though their timing is off.

Again, T2 was in what? March? So 2 quarters too late on the 821? Or are they holding back on their chip? Now I'm getting speculatory (if that's a word). Seems their two designs trend too close together.

Quality of chips? Or Canaan delivering trade mark? Have they always been so conservative in design?

I don't think the 921 is reflective of their best product with 7nm Chips.

Not sure about their overall process but hasn't it been the case going back to at least the 7 series, that they have a x21 model that kinda delivers, but is soon replaced by the x41 which tends to be the best option for that line. Generally being significantly more efficient, powerful or both.

921 more or less efficient than the s9j? Essentially this unit is best compared when looking at T2 or the turbo at 24th/s. Essentially cheap hash to watt or dollar/BTC.

Mid range unit and typical Canaan price to market to sell. You know it's a solid unit and probably the x amount you buy will work a long time with moderate maintenance. If your starting a farm right now it's worthy to consider.

Edited for typo and to reminder everyone it's 1800w again.

So if it is 20 th at 1800 watts it is a hair better then an s-9 j at efficiency on stock settings

It does get about 6th extra compared to the s9j

The real key is can I get the undeclock on it to work as well as it does on the 841.

If I can do that it will drop to 75-80 watts a th at near the 16th mark.

But if it under clocks like the 851 it will not be so good.

I have a lot of info posted on both the 841 and the 851 it shows the 841 to do very well on underclocks and the 851 to not do so well.

its a laugh and failure compared to competition....

well depends pricing is not crazy

and the 841 could underclock to get 90 or 91 watts a th.

so if this is 85 watts a th and you clock it to 17th getting 75 watts a th

compared to the m10 it is close to but not quite competitive.

an m10 = 34th at 2350 watts

this could be 34 th at watts 2550 watts

I got really good under clock with the 841.

still it missed whisper specs by a ton.

I have done a lot of good deals with avalon I need to talk with steve about getting 2 .
