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)

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.

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..

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.

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 .

While Bitmain is using a shitty 16nm chip and the chip design is beating them almost all for what you get (price).

Now its out 7nm chip with Bitmain chip-design and they will rule the market again Roll Eyes

Yes, one Controller can control up to 20 miners — i.e., up to five miners on each AUC3, with up to four AUC3s per Controller.

The Controller uses OpenWrt as its operating system, which itself uses Dropbear as its built-in SSH server. Simply configure Dropbear according to your needs (it's enabled by default) through the Controller's web interface and you'll be able to connect to the Controller via SSH.

Thanks!
Canaan is something new to me so I didn't know exactly how the controllers worked.

$2000???

Anything over $800 is too risky, and I am at .05/Kwh total.

If I used my whole 300KW and bought 180 of them it would cost 144K @ $800 ea. ~ 25 BTC with PSU's and shipping

If they were running right now they would make 5.8 BTC/mo. Maybe 5 BTC by the time they arrive.

Subtract 1.5BTC for power costs and rent, etc leaving 3.5 BTC profit the first month. After that it will slowly decline each month.

I would be lucky to BTC ROI in 10 months. That is also figuring Bitcoin will go up and I can use less BTC each month for expenses.

$2000 per unit and it would take years to BTC ROI, maybe never.

Canaan has usually started high in price and then dropped. I have been buying them since their 4.0 / 4.1 (2014?) and Bitmain and others have always been cheaper. The Avalons have been better more solid products.

The 1720 watts is going to be an issue. Yes I know 220v is better then 110v but I have a lot of 110v / 20a circuits that are going to be too close to comfort to run at that power.

If I can drop the speed a bit and get it to 1600w at the wall I might look into getting a few.

-Dave

That will be ok for winter but once it warms up avalons like to use more power. I run on 240v so I don't have a issue but yes I see what you are saying. I'm sure you will be able to undervolt it some and be fine for winter though. 1700w on 110v is fine anyways. That's right to the 20% safe zone at under 16amps constant. I believe that's why they made it 1700watts for this reason.

I am thinking November honestly. They may release info about pricing and release dates available for preorder in October though. That's usually how they do it. Price is what is going to be most important, canaan makes great miners but price is always the highest. The competitor is the M10 at the moment which keep in mind also comes with power supply at $1788. So we will round up and just say $1800-1850 shipped all said and done to your door. If Canaan stays under $2000 they have this in the bag. If over $2000, it would be iffy considering by that time the M10 will be 2nd batch and $1600. I wouldn't be very happy paying say $2300 for essentially a 28-30TH miner with power supply all said and done knowing I could have gotten a M10 miner for most likely $1600-1700 all said and done and be pushing 3 more TH. So they have to be weary of the price. Same with the litecoin miner they have coming out.

Canaan does well with design and pricing and have always been competitive to market. Speculation is really timing of release. I don't recall 821 dates announced till Nov and units not hitting the US till mid/late January'18 or maybe it's the beer right now.

If their stocking a 921/941, just release the 921 now and push 941 to market November. Forget about liquidating old inventory and capitalize on the open market. Price it 1500 and sell out in days. If it's already hitting high 20's/low 30's and is lean. Then they know what their doing and should just do what they do.

Yea Jan, I was first batch buyer for 821 and 841. They said they are releasing earlier this time the new A9 stuff so I'd assume November December. If it's under $2000 ill buy it, if it's something redic like $3000 then sadly no lol

When did they post their 8 series branch LY? Might help speculate a release.

It was around for more then 50 days prior to release of 821.

But I think avalon wants to get the a9 out the door asap. So I hope for early October.

I also hope the A9 lives up to spec. the 841 were good. the 851 not so good. but my tests involved 3 841's and 2 851's small samples to base results on.

Canaan has added the avalon9 branch to their cgminer repository on GitHub. It looks like the first of the A9 series will be called the AvalonMiner 921.

Options to tweak the voltage level ("--avalon9-voltage-level") and the voltage level offset ("--avalon9-voltage-level-offset") remain.

The A921's default temperature target appears to have been bumped up to 97°C. The cutoff temperature remains at 105°C.

The default fan speed percentage remains at 100%.

The OpenWrt firmware for the A9 series appears to be incompatible with earlier AvalonMiner models. This means that it would be not possible to run a mix of different generations on the same Raspberry Pi.

Release binaries for the A921 that incorporate the most recent commits from the avalon9 branch have not been released yet. The latest release binary of the A921's OpenWrt firmware is dated June 28, 2018 at the time of writing. The nexttesting directory is dated September 10, 2018, but is empty at the time of writing. This means that there could yet be further changes to the A921's cgminer code before its first release.

The A921's MM firmware, however, has been released. The latest release, at the time of writing, is dated September 10, 2018, and its changelog simply says:

Code:

Version 9211809-ac35af0

* First MM's firmware for A921

IF they do, i definately go for a liquid setup and push the max out of the new 7nm tech. (depending on price naturally...)

Any news about the release date yet?

I thought people were already customizing liquid cooling like GPUs for these things, not necessarily immersion. Oh course I can't find pictures or a link right now.

You can get Canaan's products through one of their distributors, like the U.S. based Blokforge, with no MOQ.
I've ordered through them for all my Avalon equipment, and highly recommend them. Great service and

I have a question if anyone on here wanna chime in.

at 1800 watts, this miner WILL be very hot. So far Canaan has been cooling all their rigs with just 1 fan. Which works with the 841s but I can testify that it is reaching a sort of limit here now. at 25-30C intake the fans are running 100% all the time and the 841s are only consuming 1300 watts.

Do you guys have any concerns with running 1800 watts on 1 fan of cooling without liquid cooling?

yes

it may not be ideal for a hot climate using air cooling in the farm.

ie your place may have an issue running them.

they may build more then 1 model.

maybe same case with less boards.
maybe shorter case with same board but less chis

efficiency would still be 60-70 watts a th

one model would be 18th other 27th

the 18 does 1170 watts
the 27 does 1755 watts

Keep in mind that the miner design will be slightly different and it will be cooled by one 140mm high rpm fan.

Um, go to the Canaan.io site and click on Official Partners at the top. It is a listing of all authorized distributors world wide. Using them you get lower shipping costs, no import fees, and most important - full factory warranty, though with Avalons it is unlikely you will ever need the warranty.

I looked at the Asia distributors a month ago. Their websites seem like it wasn't updated in a long time and the prices were horrible.
Blokforge looks good though and they serve malaysia, hopefully it isn't too expensive to ship.

thus 3 with no issues on a 30 amp

I could do 9 of these at the solar array or 297th

vs 12x 841's or 162th

quite a difference.

Being new miner I was kind of confused Canaan would release the 821 and then the 841 so quickly. If their close to a 33th unit I'll be happy. Not the wife with the added db's.

Hmmm.

Now I have to find somewhere to Install another 30 amp circuit.

Can't wait to see if this offers the same flexibility in voltage settings. They've been a lifesaver running the 841 during the hot summer.

Maybe they'll bundle 3 together and sell them like the "moose", call it the "deer". A nice home miner setup.

That would be nice, so a 30A 240v will run three? Maybe I'll wait on some upgrades if this is the case.

Why? Is a bad idea...

Mainly so I don't have to add a switch, more controllers, cabling, and create more points of failure. I fully understand the issues with upgrading firmware and that under/overclocking settings will apply to all units. I run on default settings and currently mix 821 and 841 units without issues.

Why? Is a bad idea...
As with the 7 & 8's the miners will be using different firmware and unless ran at default settings will no doubt want different Vcore voltage/offset tweaks. Even mixing within 1 family is not a good idea, aside from the tweaks, if you update firmware ALL miners on the controller are updated to it. Trust me: a 721 does not like thinking it just became a 741.-- been there, done that and fortunately was easy to back out of. Same for the 8's. RasPi's are cheap so it is best to just take the most sensible course

yeah 3 avalon long chains are close to bullet proof.
that is 12 per rasp pi.
and a rasp pi can be built for under 80 dollars

https://www.amazon.com/CanaKit-Raspberry-Starter-Premium-Black/dp/B07BCC8PK7/ref=sr_1_1_sspa?

so pick up a few of them.
it only runs into a big expense if you go to a 1200 miner build as 105 at 80 = 8040
if you go to this level you should consider a server that does more the 4 usb ports. chains that a rasp pi does.

chains of 5 have a bit more errors then chains of 4 which have a bit more errors then chains of 3 which are close to error free.

I have seen recent activity on the Avalon 851 firmware and guessing it's probably for this unless they are releasing a slower model first like they did with the 821. Hopefully you'll be able to chain these with the 8's.

So bitmain keeps selling the cheap s9's til ?

I'd guess that they are just waiting to shit on the competition. If they already have something similar or more efficient, they could sell it at 2x's current S9 price and still be cheaper than everyone else.

Interesting to note that 1720 watts is right up against the power limit for running (2) on a 220V 20amp circuit continuouosly.

20 amps /2 = 10 amps * 80% max = 8 amps * 220V = 1760Watts.

Nice design point!

yeah works for 10 amp circuits =rare
20 amp common
30 amp common
50 amp less common

would really like a mini version 13000gh and 850 watts but that is not going to happen.

They run at 40 c but drop efficiency 841's do this.

30c they are more efficient

but -1 or -2 settings help efficiency .

This year we had 1 hot week and my 841's ran in 92f 95f 97f 94f days with zero issues ... both the s9's and t1's dropped boards with those temps

I'm not entirely sure if this issue was resolved, but I thought it was firmware related. I've run my 841's all summer at
32°c to 41°c with no issues. Pushed high one day to 42°c and I dropped them to the -1 offset.

Either way, I'm "all in" waiting for this release. Great company!!!

Same, up to 40C here ambient with mediocre exhaust still . . not recommended though. Have to watch my PSU's not my avalons at these temps I'm seeing though summer now.

Fun day for announcements, glad Canaan will be ready for market soon. Was there word on pricing? 26-30th/s is broad range for them though. Speculation on end result and wattage?

Thanks for the break down philipma, always appreciated.

I wonder if the Avalon will still have the 30 deg C limit? Is that due to only being a single fan?

the pangolin M10 is 33,000 gh at 2145 or 65 watts a th

don't know if it has speed settings like the avalon 841 has

the avalon a9 is 26,500 at 1,720 = 64.9 watts a th

don't know if it has speed settings but reads 26,500 to 30,000

I would love to set it to 1720 watts as 3 fit on a 30 amp 240 volt nicely doing 5160

So

Avalon ..... A9 ...........................64.9 watts
Pangolin.... M10 .........................65.0 watts
Innosilicon. T2 Turbo................... 71.0 watts
GMO......... forgot the name......... 82.0 watts
BitMain...... S9 .......................... 100 watts

all per th

So bitmain keeps selling the cheap s9's til ?

I am looking forward to getting some avalons asap

I wonder if they will get the power usage down more over time not that it matters it doesn't i have solar i can run three of those in my house with no issue the only pain i see is the noise level those fans do 61 Db .. but id like to see the power usage go down as the th goes up that would be nicer to see . but they beat out the one i linked from Blokforge.com some place that maxes out at 33 th i think it was and usages close to 4 k WATS at max, i think it was that claimed to be 7nm due in Nov 2018 . The GMO miner B3 33TH/S miner Blokforge has as a per order. but the A9 looks like it can be better.

Along these lines, wonder if Blokforge.com upgraded my recent order for an APW3++ to the 1,800w APW7 (for free) because they know I'll be getting some of these. Safe bet Blokforge knew about these coming out and being the superb company they are them giving the free upgrade would not surprise me in the least
