Now just need for them to set a price and project a date when we can get them from their distributors. Title: Re: Avalon 8 official specs released Post by: VRobb on December 19, 2017, 07:20:06 PM Would love to get this Brand "A" miner instead of Brand "B"...!
The A-Team! :D Title: Re: Avalon 8 official specs released Post by: mikez_nj on December 19, 2017, 07:54:15 PM This is far below what they forecasted last month (14 TH/s @ 1300W). I was hoping we might get a little more, not 20+% less. I love Canaan, but this is making me re-think my purchase plan for next year.

Title: Re: Avalon 8 official specs released Post by: CryptoCrane on December 19, 2017, 08:16:21 PM Not bad, but not good enough. I suppose I should reserve judgement until we know pricing though.
Title: Re: Avalon 8 official specs released Post by: Sumfinkelse on December 19, 2017, 09:11:08 PM Nice spec and power draw but all depends on the price.
Not ordered Avalon before so if you were ordering a lot would you take their own sorcerer power supply or get your own in country?

YMMV Title: Re: Avalon 8 official specs released Post by: leowonderful on December 19, 2017, 09:43:19 PM If the price is right these units will sell out pretty darn fast. I'm hoping it'll be competitively priced against the S9 which is in pretty crazy price territory right now. No complaints about specs otherwise, hoping it'll have the usual Avalon quality.

The price increase on the S9 definitely impacts calculations:
Basically, at $2150 for the Avalon 821, you're paying approx the same cost per GH, and it's only slightly less energy efficient. Anything less than that would be a win over the latest batch of S9s. Title: Re: Avalon 8 official specs released Post by: coldbitcoins on December 19, 2017, 09:56:53 PM I'll buy one.
Title: Re: Avalon 8 official specs released Post by: fanatic26 on December 19, 2017, 10:31:19 PM The prelim specs I was given were 10TH for 1000w. I really wish that is what the final number would have been. People would have been able to run these easily on 110v at home.
Title: Re: Avalon 8 official specs released Post by: livfreely on December 19, 2017, 11:07:27 PM Are these usually good to go on the release, or are there "issues" with the software/components that need to be addressed? Should I buy one from the first batch (if I am so lucky), or wait until the quirks are worked out?
Title: Re: Avalon 8 official specs released Post by: Steamtyme on December 19, 2017, 11:30:08 PM I'm guessing/hoping these might be the same as the 741 in terms of what you'll get for Hashrate, with any luck 11 will mean 11.5 or more.
Either way I'm pretty excited and glad to see at least for the time being there are no integrated PSU's. Huge bonus here is that they are using the same AUC3 set up and cables so if you have spares from your 741's or need to get your hands on some for the EOL 741's they'll be available. Can't wait to get an order in Title: Re: Avalon 8 official specs released Post by: MinerMAL on December 19, 2017, 11:31:55 PM Nice spec and power draw but all depends on the price.

Mikez_nj, where did you find the Avalon 821 price to be $2,150? On their web page, they are only selling in bulk for 60 units, but without price disclosure. https://canaan.io/shop/ Title: Re: Avalon 8 official specs released Post by: Servfox on December 20, 2017, 12:12:41 AM I think he was just speculating on what the price might be based on the increased S9 price we saw today.
Title: Re: Avalon 8 official specs released Post by: MantaMine on December 20, 2017, 12:15:56 AM If they price these comparably with S9s, I am going Canaan. We've got to let our buying power do the talking and break up this monopoly.
Title: Re: Avalon 8 official specs released Post by: livfreely on December 20, 2017, 12:25:01 AM Will you be able to hook up an A8 to an existing A7?
Title: Re: Avalon 8 official specs released Post by: Kapz786 on December 20, 2017, 12:35:09 AM A little underwhelming but like anything it comes down to price. Will be interesting to see how they approach it on that front. But like everyone has said it's nice to move away from Bitmain a bit more
Title: Re: Avalon 8 official specs released Post by: dUCiLe on December 20, 2017, 03:47:55 AM even if this was $3000 usd a unit id buy this out of spite. i hate bitmain. there a bunch of pricks.
Title: Re: Avalon 8 official specs released Post by: TheHashcashin on December 20, 2017, 04:06:00 AM https://www.blokforge.com/product/avalon-761/
BlokForge is selling the 761 overseas for US$1400 and it has the integrated power-supply I would venture a guess that the 821 sans power-supply might come in at around US$1500. BlockForge's prices are also a bit higher than Minerwarez as applied to the 721's https://minerwarez.com/collections/new-equipment/products/avalonminer-741 https://www.blokforge.com/product/avalon-741/ $898 at Minerwarez $1200 at BlockForge So $1500 for an 821 is mighty fine! Title: Re: Avalon 8 official specs released Post by: castiel0504 on December 20, 2017, 07:02:35 AM Soo question about its algorithm, i understand that can mine BTC.. BTC is SHA256, using common sense, it can mine any coin that is SHA256 right? If that is possible, that means all coins from this list can be mined: http://prntscr.com/hpwx3e
Or did they made it "STRICTLY BTC" ? .. I'm not sure how would they do that thou, can someone please elaborate something on this topic?

No Canaan will not sell small amounts of units directly to consumers. In fact they aren't even taking on any more distributors right now. Apparently there is 10 times more demand than there is supply for the initial run. If I can get 2 - 4 units from a distributor by the end of January I will consider myself very lucky.

https://canaan.io/821annoucement/ Skip to content Canaan MENU Happy Holidays , Yesterday in Hangzhou we announced our Avalon 821, and laid out the roadmap for the 841, 861, 921 and Avalon 10 series. Avalon 741 is end of life: the last batch is being produced and is promised to customers/distributors who will receiving their final shipments shortly. Avalon 761, our solution with integrated PSU is likewise End of Life. The last batch is being built and will ship out in early Jan. 821: The Avalon 821 will ship at 11 TH (terahash) and 1200 Watts for a power efficiency of 109Watts per TH, a great improvement over the 741 which was rated at 150 Watts/TH. 841: the Avalon 841 will ship at 13TH and 1200 Watts for a power efficiency of 92 Watts/TH. I expect this to be a Q2 Product. It’s too early to talk about the 861 (integrated PSU), the 921 and 10 series, but 2018 promises to be a great year. 821 Prices: We have not yet settled on price for 821, but it will be driven by market forces and the price of Bitcoin. Demand for product is more than 10X of the supply and the pricing in the spot market clearly reflects this. As well, the price of BTC has drawn in many new customers. As soon as I have pricing I will communicate it to you. Please do not ask for it, we will tell everyone at the same time. Ship dates: After we finish the last 741 and 761, the 821 will go into production in January. I wish I had exact dates, but as of today I only have estimates. We should be able to ship to a small number of customers in late January. We will contact the customers who have been selected for January shipment, so please be patient. In February and March volumes will increase, but be advised that February has Chinese New Year and we will shut down between the 14th and the 23rd. Distributors: We are no longer accepting applications for resellers. Given the constraints in supply, we will only add a small number of new distributors. Hopefully in Q2 we will be able to open up the opportunity. If you have signed up, we will be going over our list and making our selections. New Forecast: When we have pricing we will be asking everyone to do a new forecast based on the pricing. A forecast is your estimate of how many machines you will order. Do not simply put down a large number to get our attention. We select customers both large and small and if you do not order what you forecast your entire order will be cancelled. Company. Press.

My point was that $2150 is approximately the inflection point where the value is the same as the S9 (solely based on the numbers) - so anything below that is a win over the S9. The announcement this morning makes this much better. Title: Re: Avalon 8 official specs released Post by: Flying Hellfish on December 20, 2017, 03:45:11 PM 821 Prices: We have not yet settled on price for 821, but it will be driven by market forces and the price of Bitcoin. Demand for product is more than 10X of the supply and the pricing in the spot market clearly reflects this. As well, the price of BTC has drawn in many new customers. As soon as I have pricing I will communicate it to you. Please do not ask for it, we will tell everyone at the same time. 821: The Avalon 821 will ship at 11 TH (terahash) and 1200 Watts for a power efficiency of 109Watts per TH, a great improvement over the 741 which was rated at 150 Watts/TH. Well it is nice since it will still be able to run on a usa 15 amp 120 volt circuit but it will be priced high based on what he said. maybe 2000 You can count on that one!!! There was a lot of thought put into the wording of that release and breaking it down might help some folks prepare for whats coming! When a company tells you there's a 10x supply/demand ratio skew, simple economics come into play. Meaning in an imperfect market where demand greatly exceeds supply (like 10x!!) price is always set by the most optimistic of buyers. It will always go to the 1 in 10 person willing to pay the most. Anything less is money left on the table and NO company ever wants that, trust me on that one! It's also important to notice their mention of spot price. Their telling us they know what in hand units sell for so guess what, they want that margin for themselves and their distys. No surprise really as this is what all companies do... Lastly the mention of bitcoin price in determining price, if coins stay high so do machine prices, simple as that. I don't see them caring much about being close to Bitmain in $/TH. Of course the danger is getting to greedy and that is always the fine line. Hehe but at 10x there's a lot of room to play and find out :) You can consider that paragraph as the lube for whats coming ;) Title: Re: Avalon 8 official specs released Post by: Didley1JT on December 20, 2017, 04:45:24 PM At the high value of BTC (currently... it's fallen 10% today, though), I would expect a price from distributors of $2000-$2200. Minerwarez and Blokforge are both listing the out of stock 741s over $1000. The 8 is MUCH more efficient and will fetch a premium.
I'll buy as many as I can get my hands on, provided the price isn't insane (BTC is falling, but BCH is surging over $4000 USD at the moment). Priced at or near the cost of the Bitmain S9, I will go with Canaan for the simplicity of dealing with a Distributor in the US or Canada. Title: Re: Avalon 8 official specs released Post by: Windiceway on December 20, 2017, 05:43:08 PM That's cool! I guess, it will be available for orders this spring?
Title: Re: Avalon 8 official specs released Post by: GbrilliantQ on December 20, 2017, 09:29:52 PM Outstanding news. I think the age of sha256 miners being less than $2000 are on the back burner for now. At 2k the 821 is a great deal IMO.
Title: Re: Avalon 8 official specs released Post by: QuintLeo on December 20, 2017, 11:27:08 PM This is far below what they forecasted last month (14 TH/s @ 1300W). I was hoping we might get a little more, not 20+% less. I love Canaan, but this is making me re-think my purchase plan for next year. I like it a lot better from the "not insane can only use server or VERY HIGH PRICE atx" power supply standpoint. Perhaps the posted spec is a BASE spec and you can overclock to get to the 14/1300 level? (edit) just noticed the 841 part of that one post - 13 at 1200 is pretty close to 14/1300, but I bet they have to use more chips running at lower voltage (and probably end up at a HIGHER COST) to get there vs the 821. Title: Re: Avalon 8 official specs released Post by: livfreely on December 21, 2017, 02:32:14 AM So we are going to be seeing these sell out within minutes I take it? I hope the servers for the distributors are ready to handle the influx of incoming traffic.
I will be blessed to get a hold of one when they hit the market. Of course you will have your resellers profiting from this as well, so it will be interesting how inflated prices will be on the secondary market. It would be great if BTC would take a pretty hard down swing just prior to the release ;D Title: Re: Avalon 8 official specs released Post by: sb990 on December 21, 2017, 03:14:41 AM so the avalon 8 will be using the socerer psu? and does that connect to 220v only or 110v?

The power supply that FEEDS it might require 220 VAC, or might be happy with 110 OR 220 but will run a little more efficiently at 220. I expect the 821 to end up being ballpark $3000, possibly as LOW as $2500, based on current S9 pricing. Caanan/Avalon has always had a price premium compared to whatever Bitmain product they're closest too, unless they were a TON lower on hashrate, and I don't see them pricing the 821 much if ANY lower than S9 since they're fairly close on hashrate and efficiency. They might MATCH the price of the S9 due to the hashrate difference, but they won't go lower - Bitmain will tolerate "same price" most likely because they can point at the higher hashrate AND slightly better efficiency, but a lower price would probably prompt a price war.

Agreed. I think the 821 will be between $2500 and $3,000. Very close to the S9 price. Bitmain have just shown how that price point is acceptable to consumers by selling out so quickly. I don't think a price war will happen yet though because the demand is way too high for ASIC miners and they don't need to fight for sales....They can't make enough inventory to get even close to demand. I just read on another post that Ebang's next miner will be 14TH/s priced at $3680 with minimum order of 100 units. I don't know if that price is correct but if it is and they sell out very quickly that will send a message to Bitmain and Canaan that we still havent reached the roof on the price people are willing to pay. Just my two cents. :) Title: Re: Avalon 8 official specs released Post by: Greenmine on December 21, 2017, 10:36:58 PM We still need more manufacturers.

The past few batches sit around for hours and hours (and sometimes days/weeks). And while that price point might be acceptable, the 821 isn't the S9. The S9 has it beat on Watt/TH (by a little) and Price/TH (by a LOT) if they price it the same as the S9... for a machine with 20% less output. Honestly, if the 821 is over $2200, I would be shocked.

A while back Canaan said yes you can.But... Caveat: As I found by mixing A721's and A741's, yes they work just fine together on 1 controller. BUT be very aware that if/when you apply firmware updates the update is specific to a particular model of Avalon and identified as being for 721,741, etc. Thing is, an update is applied to ALL miners on the controller. In my case the 721's did not like being told they were now 741's... Fortunately, easy to back out again. So, best to not mix models on 1 controller... Since RasPi's are cheap, painless to do.

Military electronics is COMMONLY specified to at least -40C and usually -55 C - but the PARTS themselves don't tend to be any different inside other than the "recordkeeping makes it easy to trace the lot if you have a bad part" type stuff.

I understand that, but they also have to be competitive with other mining companies. If they're not, it won't even be palatable to 1 in 10. No other mining company has a 1 year ROI right now, and right now is what matters. If the pallet pricing is to be believed, 60@ $162,525.00 = 2708.75 per miner (with PSU) to distributors. The margins have been fairly slim, so I'm still guessing the 821 will be under 3k. We shall soon see. Edit: That's the price WITH the PSUs.

They need to get used to it, we're not going to see new miner generations pretty much every year OR OFTEN LESS any more, as SHA256 miners have caught up to semiconductor state-of-the-art as of the current models. Do note that the S9 has already been out for a year and change, which ALREADY makes it Bitmain's longest-lasting "current model" - and it's looking likely to be that for another year or even 2. Then the NEXT generation is likely to last more like 4-5 years, since the S9 was designed almost 2 years after the 14/16nm node started seeing production. For that matter, if you were an early adopter on the S5 or SP20, you had something like a year and a half, perhaps 2 years with LOW electric power rates, to be able to achieve ROI - and the S7 is still profitable NOW and has been consistantly profitable it's entire existance so far if you had low power rates. Better yet - Innosilicon A2 is *3* years old, and they're been consistently profitable at anything under 5 cent power (and possibly 6) for their entire existence - but to be fair they've had a lot less competition 'till this year than has been the norm in SHA256. Title: Re: Avalon 8 official specs released Post by: lossol on December 24, 2017, 01:48:30 AM Most people don't have cheap power at .05/kwh. So it's going to come down to $/TH for most people looking into getting miners now who don't already have a bunch of them. ::)
Title: Re: Avalon 8 official specs released Post by: lossol on December 24, 2017, 02:36:50 AM Wow, at $3-4K per miner, that's going to take over a year ROI, especially with the difficulty going up each month. And if BTC keeps falling, it's going to take even longer! People been snatching up miners on ebay for over $4K because BTC was skyrocketing to $20K! Well, it's dropped a lot since it hit the high. Just last month the S9 was under $1500 & the A741 was under $1K and BTC was over $8K; so people buying new miners then could still make over 200% ROI in a year even after deducting power costs. Now that's all changed with the miners doubling and tripling in price and BTC falling. So people are going to reassess whether it's still profitable to buy a miner or not. Though you'll still get that 1 in 10 who'll buy at the high end and at any price! :o
That's why the companies selling the picks and shovels for digital gold are making out like bandits; just as the people who sold them to the miners back then in the 1850s gold rush. ;) Title: Re: Avalon 8 official specs released Post by: CM Australia on December 24, 2017, 07:14:20 AM Bitmain have just shown how that price point is acceptable to consumers by selling out so quickly. I am pretty sure this was exactly the impression they wanted to give by selling out fast for whatever reason ;) I don't know, I haven't been in the mining game as long as some of you, but they didn't seem to sell out fast to me. ??? A few months ago, when they released a new batch of any miner, their website ground to a halt, and you could sit there refreshing for 1-2 hours, not actually add anything to your cart, and it would be sold out by the time the website was actually responding. The past few batches sit around for hours and hours (and sometimes days/weeks). And while that price point might be acceptable, the 821 isn't the S9. The S9 has it beat on Watt/TH (by a little) and Price/TH (by a LOT) if they price it the same as the S9... for a machine with 20% less output. Honestly, if the 821 is over $2200, I would be shocked. Pallet price of 60 units A821 = $150,525 divided by 60 = $2,508.75 a unit (without PSU). Add PSU for around $200 ($2,708.75) and re-seller mark up if buying less than 60 units and were around the $3k mark. Title: Re: Avalon 8 official specs released Post by: Didley1JT on December 24, 2017, 10:33:27 AM They're not stupid. I'm pretty sure they added the pallet prices knowing we would all start talking about and they could then gauge the market's response.

Most miners are BADLY spoiled, an ROI of less than a year is AMAZINGLY FANTASTICALLY GOOD when you compare it to most things you can invest your money into. Tradeoff is that it IS higher risk than most of those other investments. If Bitcoin stays above $12000, an 821/841 or S9 should easily achieve ROI in a year at the $3000 level (presuming the S9 don't lose a hashboard or die) if you have a SANE electric price to mine with. Folks paying over 5c/kwh are killing THEIR OWN chance at ROI if they insist on mining Bitcoin itself through excessive overhead cost. Title: Re: Avalon 8 official specs released Post by: leowonderful on December 24, 2017, 09:33:39 PM When does a ROI of more than a year ever make sense? It doesn't.

Anything less than a year is decent for me, anything over I don't consider.Especially on something as risky as a product that can swing a price range of 40% in 1 day?

It looks unlikely from what people are saying about pallet prices, unless the official distributors like crypto and blokforge get them for cheaper? Title: Re: Avalon 8 official specs released Post by: QuintLeo on December 26, 2017, 10:32:32 PM If Bitcoin collapses under $10k very soon and STAYS there for a month or more, I'd bet against the Avalon 821 being priced under $2500 at "retail pricing" when it is released.
Given the current recovery from what appears to have been a market correction, I would bet that it is unlikely to be under $3000. Up side - unlike the Innosilicon A4+, the distributors seem to be willing to sell singles, and NO worries about customs hassles if you're in the same country as one of them (or in the EU if there's a European distributor somewhere). Title: Re: Avalon 8 official specs released Post by: Zyekad on December 27, 2017, 01:03:31 PM Lets compare and do some analysis of where Canaan NEEDS to be for their units to make sense:
S9 at 13.5 TH/s - current price (last batch, inflated price) - $2,725 ea. A821 at 11 TH/s - estimated price based on 60 units, bulk pack, reseller - $2,885 ea. S9 power consumption - daily cost (at $0.10/kWh) - $3.18 A821 power consumption - daily cost (at $0.10/kWh) - $2.88 Avg. Daily Profit from S9 - $32.50 Avg. Daily Profit from A821 - $26.23 Days to recoup investment (not counting power supply, shipping, customs, etc): S9 - ($2725/$32.50) - 84 days - then a profit of $32.50 per day A821 - ($2885/26.23) - 109 days - then a profit of $26.23 per day 1 year ROI: S9 one year ROI - $11,862.50 A821 one year ROI - $9,573.95 I know things change in regards to difficulty and other factors, but if Canaan doesn't lower their price it won't make sense to purchase their product compared to the S9's, even at the current insanely inflated S9 pricing. This is really sad, since I do believe Bitmain needs some serious competition. Hopefully Canaan can see this and will end up pricing these similarly to their retired 741's since around the $1400 range would make sense to get these units, but at $2800+ it is ridiculously overpriced for the hash power you are getting with the amount of watts they use. Just my 2 cents...

We have seen this in many industries since trading has been invented. They most likely can put weaker companies out of business if they like. Interesting thought. I guess it depends on whether Bitmain would prefer to maximise profits by pricing just under or around Canaan's price or whether they want to make life miserable for Canaan and way under cut them when they release the 821. With the shortage of supply of chips/miner's vs consumer demand my guess is that Bitmain will remain priced just under Canaan to realise the most profit. I think this because if they under cut Canaan at $1600 or something like that they will sell out in a day and leave Canaan as the only option available anyway. IE Bitmain would sacrifice much profit for a temporary f**k you to Canaan. I think the low price would only work if Bitmain could keep up with consumer demand for a prolonged period of time. Just my opinion of course. :) Title: Re: Avalon 8 official specs released Post by: CM Australia on December 27, 2017, 11:15:28 PM I was just thinking of another option which would be a dirty move.
If Bitmain really wanted to mess with Canaan they could under cut them and instead of releasing 1000-2000 units as a batch they could drip feed releases of around 100 S9 daily while they wait for more chips and then repeat the process over and over again so everyone is constantly waiting and trying to score a cheap s9's instead of 821's. ha ha Title: Re: Avalon 8 official specs released Post by: score1more on December 28, 2017, 12:35:35 AM aren't these two companies making money hand over fist already? They've already "tested" the miners for 6-9 months, and now their new test batch has arrived and they shipped out the 741s.
I don't see how either company can lose in a market like this. It's just who's going to have a bigger win. Remember price elasticity in economics? Title: Re: Avalon 8 official specs released Post by: IAmLoco on December 28, 2017, 02:02:41 AM im interested with these new avalon miner but I have a question
does the 7 (i guess the 8 will have the same logic) push or pull the air from the fan I use currently duct shroud for my s7 and would like to keep using this for my next avalon miner thanks Title: Re: Avalon 8 official specs released Post by: QuintLeo on December 28, 2017, 06:37:41 AM Any idea if they'll use the same PSUs as the 741s? More specifically the EVGA Supernova 1300/1600 G2? I notice it's 8X6pin versus the 6X6pin the 741s used. Im assuming it can because the S9 can use the EVGAs with 9X6 pins. If you are using ATX power supplies you are so doing it wrong. People should know better by now. Not automatically true - some like the ATX power supplies because they intend to use them for other stuff once the ASIC miner dies - or in my case I would use my EXISTING G2-1300 or X-1250 supplies because I have a couple floating around not currently being USED for anything. 8 PCI-E connectors on 1200 watts works out to 150 watts per connector - the EVGA "dual" cables should be ok as they apparently use 16AWG wiring to the first connector, then feed the second one with 18AWG, on the power and ground leads. There IS a 20 AWG wire in there, but that's a sense wire that doesn't carry significant power. So basically only buy ATX power supplies if you are planning on eventually using them with something OTHER than another ASIC afterwards? For economic sense, yes. There actually is one other possible reason - most Server-type power supplies don't provide as much power capacity on 117VAC as on 234 VAC - if you don't have 234VAC available and can't have your placed modded to do so, the ATX option (especially on 2 smaller PS) gets a LOT closer on cost since you would then likely be competing 2 small ATX vs 2 small server supplies. Title: Re: Avalon 8 official specs released Post by: ConnerM on December 28, 2017, 07:59:49 AM If you are using ATX power supplies you are so doing it wrong. People should know better by now. We have over 120 EVGA 1600 Titaniums in our farm. They run our S7's, S9s, and Avalon 741's. They run our big GPU rigs. We can run our gear at 120v, 208v, 220v, or 240v. We push them pretty hard. They have a 10 year warranty, though we have never had a unit fail. We have units that have been in operation 24/7/365 for over 3 years without a lick of problems. We have run multiple generations of gear on them. If the next gen gear have different power requirements, we should be able to resell them used for close to or even what we paid for them, so they act as a store of value vs. a real operational expense. Granted our farm is very small, but I always thought standardizing our power gear with high end ATX PSU's as an investment and it has worked out very well so far. We can use any PSU in our farm to run any gear, and they do it well. Easy. And they are rock solid. We tried a batch of Bitmain's APW3 a few months ago, 12 units, and 2 were DOA right out of the box. I thought they were junk. I don't know, take all this with a grain, your mileage may vary, but I feel really good with those ATX's powering our gear. It's been worry free so far.

Title: Re: Avalon 8 official specs released Post by: alh on December 28, 2017, 07:23:52 PM As for Bitmain -vs- Caanan pricing, I think the most recent sale of 741's on Blokforge to be instructive. They literally sold out in minutes. They had 100 units, and well over 1000 folks interested. They set a limit of 2 per order, and still disappointed a lot of folks.
With the current FOMO (Fear Of Missing Out) attitude surrounding Bitcoin, there is plenty of money to go around, and neither Bitmain nor Caanan has any reason to engage in a price war. Both will sell all they can produce while BTC price holds up, and they are production constrained (probably by ASIC fab). Title: Re: Avalon 8 official specs released Post by: fanatic26 on December 28, 2017, 08:17:00 PM The manufacturers work together more than against each other.

A while back Canaan said yes you can.But... Caveat: As I found by mixing A721's and A741's, yes they work just fine together on 1 controller. BUT be very aware that if/when you apply firmware updates the update is specific to a particular model of Avalon and identified as being for 721,741, etc. Thing is, an update is applied to ALL miners on the controller. In my case the 721's did not like being told they were now 741's... Fortunately, easy to back out again. So, best to not mix models on 1 controller... Since RasPi's are cheap, painless to do. I sent them an email to see if you can mix and match 741's and 821's on 1 controller. The response was that they use different firmware. I take that to mean you won't be able to set the machines up on the same controller. Like Notfuzzy said you should just have a 2nd controller ready to go to avoid downtime.

No reviews or how to guides yet. Best bet is to run your 821's on a new controller just for them. Title: Re: Avalon 8 official specs released Post by: fanatic26 on January 16, 2018, 04:32:34 PM You will want to run them on a separate controller anyway.

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. 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 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 Yes.

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. Title: Re: Avalon 8 official specs released Post by: frodocooper on January 20, 2018, 10:38:20 PM 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. More accurately, you would be flashing a Canaan-customized OpenWrt image (https://github.com/Canaan-Creative/avalon8-docs/wiki/AvalonMiner-821-firmware-downloads#Controller_Firmware) 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 (https://wiki.openwrt.org/doc/techref/luci) is a package within OpenWrt that provides you with the web user interface. 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. Yes. This is because all Controller software before version 20171216 does not have any code that recognizes the A8 series. 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. 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 (https://github.com/Canaan-Creative/cgminer-openwrt-packages/tree/master/cgminer/files). 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 (https://github.com/Canaan-Creative/cgminer-openwrt-packages/commit/8e0e2f0e66473e99dbf1ad8f956254da914d9af2) — 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. 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. 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 (https://github.com/Canaan-Creative/cgminer-openwrt-packages/commit/b5ed4f0875094a4a12128ce3ca7137641bb81588).

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.

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?
Title: Re: Avalon 8 official specs released Post by: QuintLeo on January 23, 2018, 09:40:57 PM (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.

They haven't shipped out yet from Canaan, but they are available. I think they are on schedule for the pre-order shipping from Blokforge of February 7th; based on the last mass email from Canaan. These units were priced at a "premium" due to the fact that I think there were only 200 available for the early ship date, half with crypto universe and the other half with Blokforge. The price they originally charged I'm sure had everything to do with capitalizing on the surge in price of BTC, I'm not shocked Canaan went that route, but it was a far cry from the estimated 200$/TH they were estimating back in November. If the current price of BTC stays relatively the same I do think that Canaan will reduce the price point to be closer to their original estimates, but the price will be subject to distributor mark ups. As for the snatching up, people did slow their roll a little at least that's what I saw with stock actually sitting out a while on the Blokforge site. Probably due to the high price tag and the drop in BTC value. They are still selling out though, and the nice thing right now is Blokforge posts in their thread for Forum members when they have extra available from orders that fall through.

The price of A821 is $2200 USD per unit for March. The price of PSU(1800W 93%) is $110 USD per unit. The current spot price of A821 is $3500.00 USD per unit. ;D ;D ;D ;D I think with $2000 USD price tag they would gather more attention. But who cares , they are going to sell off anyway.

They just raised their bulk pricing drastically. The A821 by itself is $3150 at bulk pricing. Which is going to take over a year to breakeven at $0.10/kWh and if Bitcoin remains in a bear market, you can forget about breaking even. Most people don't or can't factor in the declining revenue stream as difficulty goes up weekly and more miners come online. That 1 Year ROI keeps stretching month by month so that 1 year is no longer 1 year a month later!

I think on paper the 741 and 821 draw the same wattage don't they? If so, then it should be feasible.

Tradeoff is the AUC becomes a point source for failure on multiple miners, as does the controller. Given that the AUC is a very non-standard part, that's a significant potential ISSUE - and one reason Avalon may be short on the AUC units is folks with multiple miners buying "spares" for "just in case one FAILS" since they can't get a replacement for it anywhere else.

When you say you base the price of your miners depending on bitcoins price you’re just lying If it doesn’t go down when the price of bitcoin falls.

Title: Re: Avalon 8 official specs released Post by: QuintLeo on February 10, 2018, 09:47:52 PM I cant help but wonder what is ppl thinking for paying 3500$ for a 11th miner? thats a 14 month to ROI without any diff increase. At 5 cents electricity, it is now 16-17 months, 480-510 days. At 10 cents electricity, it is 20 months, 600 days. That isnt possible. This is without difficulty increase and new stronger machines coming in.... Price should go down to $1100-1200usd? Lucky for you someone else beat you to checkout because ROI is now 848 days for an A821 at $3500 & 0.10/kWh. Which basically means never! All those ebayers are still paying $3500 for an S9 and $2000 for an A741 too. These people do not know wat they are doing.... Do keep in mind that when those prices were SET Bitcoin was almost double what it is now. I DO agree Caanan needs to drop the prices to reflect current Bitcoin pricing - they've been WAY too slow to respond to the crash.

Newer hardware is coming, they know this and they are trying to do everything they can right now to make their last ditch profit. Because shit, they may not even be around in 2 years time. This looks like it will be the case. In general, mining would be unprofitable for all if it goes this way. I wrote two topics on this recently. It seems that there will always be high difficulty increases because the average buyer does not take into account difficulty increases and other risks. News and media also push them into mining. If this difficulty increase keeps up, the winner wont be the home miners or the big miners, the winner will be the fellow who just buys bitcoin and holds it. Why? Because difficulty rise up so much that even with the cheapest electricity, u gonna make more just holding bitcoin. So, If bitcoin drops = miners will make huge losses. Bitcoin holders make some losses. If bitcoin price stagnates = miners dont make money because difficulty rise alot over time and higher cost miners switch off machines while lower cost miners make like 50-60 bucks per machine LOL. Machine will likely break before they break even. Bitcoin holders make nothing. If bitcoin price rise alot = miners make some money. Bitcoin holders make alot more money Asic manufacturers will still make money from selling ASICS but make nothing much or lose money from mining.

Yes I got my money back, but I still got Jipped because well as you can see the price of miners have all just went up and yet to come down. I’m still kicking myself for trying to try a Canaan unit.

Doesn't seem entirely reasonable or fair to Caanan. Maybe a little, and maybe you’re right. But to me, when they’ve got them listed as an “Authorized Distributor” then they should have some responsibility to keep their name clean. At the time they were the only Authorized distributor on Canaan’s website. Oh, that and they’ve got their 11TH miners listed at $500 more than Bitmains S9 which does 2.5 more TH a second.

I guess I'll see what outlet temps I've got first, but my basement this time of year is pretty dang cold, and I'd just as soon trade off some noise if appropriate.

Yeah, but I wonder if they are *trying to keep* the outlet temp at 70. The 741 runs at approx 90 and thats what set value it has in the cgminer code. So someone must want the 821's to be at 70. I'd hate to adjust that and burn up an 821. I suspect the current/voltage changes pretty dramatically as the temps rise on the ASICs. And from others testing, the -1 undervolt has the opposite effect - hashrate and wattage goes UP, not the other way around... Be curious of others findings?

And from others testing, the -1 undervolt has the opposite effect - hashrate and wattage goes UP, not the other way around... Be curious of others findings? Bit more info here after running these for a few days. a) I would change the "min fan speed" in the configuration to 50, from the 100 as the firmware came b) I would *NOT* change the max temp from the default of 70. I went back through all the git merges on the 821 code and that max temp was specifically changed from 90 which the 741's ran at to 70 and my guess is they want to keep the chips *COOL* and not let them get hot. The 105 number is still in there as the autoshutdown number, but that's a pretty scary temp and I would avoid at all costs letting it get much above 80 or 90 for any length of time. Because they are trying to keep the ASICS cool, if you shut one down that 50% min fan will still force enough air over them to cool them. The problem with aluminum is it works both ways, it will dissipate heat when used to cool, but if not cooling it will hold the heat and cook things. By lowering the min fan to 50, if your environment will allow for an inlet temp that can keep the outlet at 70, with a lower than 100% fan, the fan moderation will kick in and you'll save some noise. I noticed this today, my room temp was way below 30, and the outlet was 70, but the fan was at 85% which was way better than the default of 100 all the time. Just remember, you don't want them above 70 for any length of time (or so it would appear that Canaan doesn't) but if your environment will allow you can drop down the min fan. But leave it at something that would rapid cool the headsinks if the unit drops offline or is stopped. ps. this is why I pretty much go to an *unplug enet* when I want them to shut down gracefully. This keeps the rPi controller in the loop and once they run out of hash, they go to the min fan temp while they cool. Then I can unplug the I2C cable and turn them off.

Thanks Correct. 1 rasp pi will control up to 20 miners and any settings changes to the controller are applied to all miners connected to it. That's what I figured but wanted to make sure. Rather not get to the data center and find out the miners can't mine because they needed IP addresses as well. They are essentially mindless dummies that can't do anything without that raspberri pi or equivalent controller, unlike the antminers which operate independently. This makes is much easier. Thank you all for the help. MINE ON! Title: Re: Avalon 8 official specs released Post by: lrowland21093 on February 21, 2018, 04:29:20 AM After setting up my A821 today, I made some interesting discoveries that I think explain what is going on with the voltage offset tests in HagssFin review and with what others found with the fan % and temp cutoff. Several values are hard coded into the cgminer startup command and do not have some of the settings that are in the screen. For example, the voltage offset is always set to 0 and even if you enter -2 in the miner configuration, it will not get passed to the cgminer startup. The same holds true for the fan range (hard coded to 50-100) and the frequency.
You should be able to see this by going to the Processes screen and looking toward the bottom for the cgminer startup command. You should be able to see what is hard coded and then entering things like voltage offset doesn't get entered here. To get around this specifically for voltage offset, I put the following in "More Options" similar to what akadamson suggested: --avalon8-voltage-level-offset -2 Here is a image of the Process showing te hard coded voltage offset as well as the override on more options - note I also had my offset int he CGMiner Config screen set to -2 but that did not do anything... https://imgur.com/IhP3kSL (https://imgur.com/IhP3kSL) For those who don't know or are new to this, the command line options can be found here (just look for the avalon7 options and maybe the options for avalon8 will be similar): https://github.com/Canaan-Creative/cgminer/blob/master/README (https://github.com/Canaan-Creative/cgminer/blob/master/README) Title: Re: Avalon 8 official specs released Post by: DPoS2 on February 21, 2018, 04:40:17 AM After setting up my A821 today, I made some interesting discoveries that I think explain what is going on with the voltage offset tests in HagssFin review and with what others found with the fan % and temp cutoff.

The shutdown temp on both that 741 and 821 is 105 in their respective versions of cgminer (you can see the 7's version by selecting the avalon7 branch in git) I found that the min fan value was picked up from the configuration screen, by default it was 100%, but if you changed that to 50%, you would get the 50-100 range in to the process listing of startup options. I had tried the -x values, but didn't even think to look at those being overriden. Title: Re: Avalon 8 official specs released Post by: WBF1 on February 22, 2018, 04:00:58 AM Are you guys tweaking frequency as well or just voltage?
Title: Re: Avalon 8 official specs released Post by: lrowland21093 on February 22, 2018, 06:54:42 AM Tried changing the frequency and so far, it doesn't work well with any setting other than 650. I tried 600, 625. 636, and 675. For each one I lt it try to hash for about 30 minutes and each time the overall hash rate barely got above 2TH. Setting it back to 650 and it went back to about 11TH immediately.
My guess is that the chips on the 821 are pretty much set to only work right at the 650 frequency. Of course, I could be doing something wrong so maybe someone else will have success. So it looks like one setting that does work well is the "--avalon8-voltage-level". I set mine to -1 (range is supposed to be -15 to +15) and it is running cooler by 10 degrees and the fan is staying around 65-70% with a hash rate about 9-10TH. (Plus, it is much quieter now.) I also changed the target temp to 90 which makes the fan run more like the 741s. I'll let it run overnight and take a screenshot tomorrow. It will be interesting to see if there are power use differences when HagssFin retests. Here is what I put in More Options: "--avalon8-voltage-level-offset -2 --avalon8-temp 90 --avalon8-voltage-level -1" Title: Re: Avalon 8 official specs released Post by: lrowland21093 on February 22, 2018, 02:00:21 PM As promised, here is a screenshot showing the new settings. it is really working well now and is as quiet as the 741s. 8)

Here is what I put in More Options: "--avalon8-voltage-level-offset -2 --avalon8-temp 90 --avalon8-voltage-level -1" I'm more than a little leary of setting the temp to 90. Most chips today are rated for -20 to 80C, with a few exceptions that go to 105C (rare exceptions). And because *specifically* the developers at Canaan, changed the 90 which the 741's use to 70 in the code. I did see that overriding the voltage-level-offset made a difference, haven't tried the other, but for now, I'm going to leave mine running at a max temp of 70 and just work on keeping the inlet temp down. Title: Re: Avalon 8 official specs released Post by: akadamson on February 22, 2018, 03:51:50 PM Further to the above, I had provided my findings to Canaan and received this email in response.
e.g. there is an option to set a -2 to 1 voltage offset, this worked with the 741s, but with the 821, that option is there in the web interface, but the command that is actually used to start the miner, *always* forces the 0 offset and ignores the value set in the web UI. >> This option is for A741, sorry for we didn't delete this function from A821's firmware. There is one other around the min fan speed, it defaults to 100%, what probably makes more sense is to set to that 50 by default. The outlet temperature is set to 70, where as on the 741 it was 90, because of this with the default min fan set to 100%, the fans run at 100% speed whether they need to or not. >> We locked the fan speed in the A821 firmware since its chips cannot take high temperature. Again, I wouldn't change that 70 on the temp... the fans shouldn't be a problem and it appears the undervolt will be coming out soon Title: Re: Avalon 8 official specs released Post by: lrowland21093 on February 22, 2018, 05:19:58 PM Again, I wouldn't change that 70 on the temp... the fans shouldn't be a problem and it appears the undervolt will be coming out soon Good information from Canaan - thank you for contacting them (just gave you one of my few merit points I have to give :)). I just changed the temp target to 80 - the fan seems to be still tolerable and keeping the steady chip temp at 70 with this setting. I agree that when they have a working undervolt that could be a better options.

It does say under CGMiner Configuration, Minimum Fan%(Range: 0-100, Default: 10%) but I can't remember if the original controller image had the same 10% default listed. Title: Re: Avalon 8 official specs released Post by: akadamson on March 11, 2018, 11:33:37 PM I wonder with the new updates if Canaan still recommends setting the minimum fan to 100% It does say under CGMiner Configuration, Minimum Fan%(Range: 0-100, Default: 10%) but I can't remember if the original controller image had the same 10% default listed. because the max temp is 70 on the 821, not 90 like the 741, you will find that if you can't keep the inlet temp to 27 or less, that the fan is going to run at 100% anyway. The compromise I made was set it to 70 instead of 100. But unless the environment they are running in is really cold, the fan is going to run up to 100 pretty much anyway. And I don't think I'd let them run about 75 for very long, the chips they use are very sensitive to over temp and one of the recent changes to a fix to set the over temp condition.

a) you *can* set the fan speed down to something lower than 100% (I set my 821's to 50% for example) but it will take an inlet temp of around 25-26C to see the fan spin lower than 100% b) the new ASICs are way less temp tolerant than the old ones and as such Canaan doesn't recommend running them over 70C - which is why the fans speed was locked to 100%.

Title: Re: Avalon 8 official specs released Post by: ccgllc on April 22, 2018, 04:20:23 PM As was reported (and deleted) on another thread, it appears Canaan has reduced the intake air specification from 40C to 30C (104F to 86F).
https://canaan.io/wp-content/uploads/2018/03/841-datasheet.pdf This means the equipment is no longer spec'ed to work within ASHRAE guidelines (the industry standard). Most new computing equipment is designed to meet the ASHRAE 2015 thermal guidelines of at LEAST class A2 (up to 35C) and most handle class A3 (up to 40C) or class A4 (up to 45C). 30C is not even class A1 (32C). So Canaan is now making "industrial" miners that are not designed for modern industrial data centers??!?! The only way to be in spec now is to either be in an old inefficient data center that still provides the classic 18-27C cooling air or some similarly costly environment (unless your data center's intake air never exceeds 86F - possibly doable in northern regions). Personally very disappointed with this, since I previously considered Avalons my premium minor (over my S9s). Title: Re: Avalon 8 official specs released Post by: HagssFIN on April 22, 2018, 04:22:37 PM I think that they should test it some more and be as accurate with the specs as possible.
I think it should be possible to class it as a A1 class or A2 class device. Title: Re: Avalon 8 official specs released Post by: ccgllc on April 22, 2018, 04:27:03 PM I think that they should test it some more and be as accurate with the specs as possible. I think it should be possible to class it as a A1 class or A2 class device. Agree with that, however many have been purchased with the understanding they were class A3 devices (at least in terms of acceptable maximum cooling air temp). A3 is really considered the minimum for modern data centers. Title: Re: Avalon 8 official specs released Post by: HagssFIN on April 22, 2018, 04:30:26 PM I sent an email to Steven, let's see if they have some lab test info or etc. which could help to specify the A841 technical specs more accurately.
Title: Re: Avalon 8 official specs released Post by: ccgllc on April 22, 2018, 04:44:04 PM I sent an email to Steven, let's see if they have some lab test info or etc. which could help to specify the A841 technical specs more accurately. In my mind, this is more of a "recall" than just a change in specs. My data centers, with over 150 miners in it, is outside air cooled. In my area, I might have a few afternoons a year, in an exceptionally hot year, where the outside air is > 40C. I will have MONTHS of afternoon air temps > 30C. This is a huge deal. (Full disclosure: Most of those miners were previously bought S9s with 40C temp ceilings. With my latest order, there will only be 16 Avalon 8s in there, but they WERE my expansion choice - now I may need to reconsider.)

At least it wasn't a shadow delete, as I can see it missing now. I guess an official reseller of Canaan deemed my post, which is pointing out a possible fire hazard to clients, as off-topic and needs to be deleted. I've worked at datacenters for over a decade, and if anything widely used changed from 40C to 30C, it would be something that needs to be addressed publicly and quickly. 30C even in active cooling situations could be near impossible in the case of running on backup power; however realistically most mining farms are passively cooled and 30C is only possible 365 days a year in very select locations. Also, this change was done on Blokforge's website as well without any email notification, so it is indeed on topic. I already cut all business ties over Minerwarez, and wasn't alone when I left with several other known BCT members as well as personal recommendations I had made due to shady business https://bitcointalk.org/index.php?topic=2277516.140 This squelching has left me with no option for purchasing from Canaan or recommending them. ---- A reply of yours, quoted below, was deleted by a Bitcoin Forum moderator.

Quote I noticed on both the Canaan website and Blokforge that the heat ranges have been lowered by 10 degrees Celsius. It use to be 40, and now it is 30. https://bitcointalk.org/index.php?topic=2616205.0 I didn't get an email about this, and this much of a change would put several miners and farms out of range for this. Usually that would result in a recall or notification as the norm has been 40C for most miners up until now.

At least it wasn't a shadow delete, as I can see it missing now. I guess an official reseller of Canaan deemed my post, which is pointing out a possible fire hazard to clients, as off-topic and needs to be deleted. A reply of yours, quoted below, was deleted by a Bitcoin Forum moderator. Posts are most frequently deleted because they are off-topic, though they can also be deleted for other reasons. In the future, please avoid posting things that need to be deleted. Quote I noticed on both the Canaan website and Blokforge that the heat ranges have been lowered by 10 degrees Celsius. It use to be 40, and now it is 30. https://bitcointalk.org/index.php?topic=2616205.0 I didn't get an email about this, and this much of a change would put several miners and farms out of range for this. Usually that would result in a recall or notification as the norm has been 40C for most miners up until now. Unless it was a self-moderated topic, your post was deleted by -ck or frodocooper. I agree that the deleting and modifying topics here at the hardware section has lately maybe been little too aggressive than needed.

We will do a heat test as we run 95 f in the summer That is 35 c Title: Re: Avalon 8 official specs released Post by: Shazam!!! on April 22, 2018, 10:56:32 PM I don't know if it helps, but I've had my 841's running at 37°c, on warmer days in my area. They seemed ok with it, as I didn't see any relevant hardware errors, and the units were slightly warm to the touch. PSU's remained cool the whole time. I try not to run them "out of range", but had no choice.
Title: Re: Avalon 8 official specs released Post by: kano on April 22, 2018, 10:59:57 PM Wow, that is sad that they deleted my post. "They" is a mod - no one else can delete posts in this thread except someone delete their own posts.... Title: Re: Avalon 8 official specs released Post by: NotFuzzyWarm on April 23, 2018, 02:27:01 AM In all fairness, the deleted posts about temp range change were in the Blokforge thread so not really on-point with the topic. Which leads to my reply on it that was also deleted.
On that... 1st I have to say that so far my 841's have been happy running in up to 93F (34C) ambient leading to chip temps from 88-90C. I see similar temps on the 721's and 741's I have. However - running at those temps seems to come at a price: power usage. After running several tests, with a solid 230V coming from my always on-line UPS's both ones from Cyberpower and Tripplite reports typical power using -2 offset as 1.51KW - all long way away from much lower power reported by others when running in lower temps. Also hate to say it but my s9 batch-1 (no Vcore regulators) running in the same area, chip temps 99-102C only pulls 1250w... Title: Re: Avalon 8 official specs released Post by: ccgllc on April 23, 2018, 05:56:01 AM Yeah, my reply was deleted as well. My only rationalization was that it was on the BlokForge thread instead of something specific to Avalons - thus my slightly reworked post here.
Title: Re: Avalon 8 official specs released Post by: mgoz on April 23, 2018, 01:41:10 PM I don't get how any of you guys are managing to stay running above 30C. My ambient room temp is around 20C with windows open and it's still been snowing here. I have a couple 841's daisy chained and one just stops hashing if the intake temperature reaches 30C, although I suspect something else may be wrong because it arrived with a dent and the fan seems to stop or slow considerably at random times. Last time it stopped hashing I was seeing temps at 28/133C with fan at 90RPM/100%. I am not sure why there is such a large difference in room vs intake temperature or why the fan reports it's at 100% at that speed.
I was going to purchase more of these, but if I am having problems in cool weather, it will be even worse in the Summer. I have some 821's outside in the shop that show intake around 15-20C. I was going to move everything out there and have them exhaust directly out of the building and keep a large box fan on the intakes, but a box fan on my 841's now is not reducing intake temperatures at all. I've been trying to blow cold air in and hot air out. They constantly run at 28-30C in a 20C room. Canaan said it was an intake temperature issue, but only one unit is affected. Title: Re: Avalon 8 official specs released Post by: PeaMine on April 23, 2018, 03:29:24 PM Since it's a product they sell on their site, and they also changed their specifications, I couldn't see how it's off topic.
I am a paying customer of theirs, and Canaan as well since the Avalon 6. I also wrote up several positive reviews as they are still working as advertised, and several business affiliates have purchased based on my recommendation. It's a question about a product they are selling, and they are in the business of selling said products. It will also affect all of their customers except for those in very cold locations year round so it needs to be addressed before end of Spring I would think or thousands of miners will be running well out of their new safe operating range. I remember the 841 had 35C at one point listed, while the 821 had 40C listed, which makes sense as it is the same cooling system but less power. I purposely chose the 821 over the 841 given this specification on their website. At this point I would have been better off going with the S9, especially at the current price and previous pricing. Both the 741 and 721 were rated at 40C as well https://blokforge.com/product/avalon-741/ However to drop all 8xx to 30C without notice after stating 40C, is unprecedented in the ASIC community as far as I know. Title: Re: Avalon 8 official specs released Post by: Shazam!!! on April 23, 2018, 07:05:54 PM Here are my temps today. They are hashing away. Pretty much regular for me to see these temps.

Also fan and voltage settings? I've ran mine at 10% and -1 since I received them, but going to try changing the fan back to 100% to see if it helps at all with the one that keeps crashing. Seems like the fan keeps slowing when it shouldn't be.

They are currently located in my garage, and I can't "air" it out until I get home from work. Soon, they will be moved to my basement for the summer. I also want to add, I have 2 M3's running with them as well, and I believe that they are the real heat source. They're little torches, compared to the 841's.

Here is all the 841 firmware and note the original had an error in that it won't show you when you are in a bad heat range and potentially damaging the ASICs, but the new one will and will shut you down :)... https://github.com/Canaan-Creative/avalon8-docs/wiki/AvalonMiner-841-firmware-downloads Pretty much everything shipped with the 8411802-1e73b80 version of the MM code, and the 8411803-14bf10 came out about a week after the 841s were released to the general public. I updated all of mine and have had no issues... but I also haven't ran them wide open with no regard for the temperatures either. I guess while I'm on this topic. The undervolt stuff wasn't supposed to be in the firmware, and not all units will undervolt to -2. 2 out of 5 of mine, will not run (or run pretty wounded at -2), but change them to -1 or 0 and they run just fine with no significant delta from the other 3 Title: Re: Avalon 8 official specs released Post by: ccgllc on April 24, 2018, 01:45:39 AM I guess while I'm on this topic.

Title: Re: Avalon 8 official specs released Post by: akadamson on April 24, 2018, 04:58:41 PM All this discussion about power, temps, etc. has caused me to chase a rate hole, but the result was enlightening.
If you use a sorcerer PSU, you will notice that the fan sucks instead of blows. This means that in order to have enough attachment length to the power supply connections, you probably are placing the PSU above the 841/821 with the 2 fans opposite (841 vs PSU), and most likely you are exhausting the heat from the PSU out it's back and right back into the 841. I ran mine on a different supply that I have that's fan blow the opposite way and the difference was 2-3C in inlet temperature difference. This afternoon, I'm planning on seeing if I can flip a fan around in a sorcerer and cause it to suck in the same air that the 841 is and exhaust it forwards like the 841s and see if the inlet temps don't drop by 2-3C as a result. Curious if anyone else noticed this or resolved it?

I've thought the same thing about going 180° with the fan, but haven't been able to make time to experiment. I've also considered, adding length to the cables. Please be sure to post your findings.

Title: Re: Avalon 8 official specs released Post by: akadamson on April 25, 2018, 01:12:11 AM So the improvement was around 1C... maybe 2, but it's pretty hard to really find the 2C, but at least all the hot air is going in the same direction as the *HOT* air :)...

Because if you just selected -1 in the web UI, that didn't make the change, you have to add the "--avalon8-voltage-level-offset -1" string in the more options line in the configuration the 0 - zero option is hard coded no matter if you selected the -1, -2, etc or not. :)... little known detail. BTW, from 0 to -1 on mine will show an approx .150-.2 Th drop per miner in the rate, but the outlet temp will change by a couple of C too Title: Re: Avalon 8 official specs released Post by: ccgllc on April 25, 2018, 07:03:38 PM How did you do that?

All you have to do is look under the status->processes tab in the web UI and scroll down till you find the cgminer process and you'll see how it was started and you'll see that if you tell it to be -1 in the UI, it will still be 0 in the processes. Doesn't matter which one you select, it will always be 0. Adding it in the more options will add the string to the end of the command launch string and it will override the 0 hardcoded value to whatever you specify, and it doesn't need to match what is the UI.

I completely get why, there are some 821/841's that *won't* run at -2... I have 2 841's that wont for example, but -1, 0, and +1 they run perfectly. That same email is where they told me the reason for the 100% fan, and if you look in the ccminer code, while the 741's had a fan moderation temperature of 90C, the 8's that was changed to 70C. The high end shutdown limit is 105 I believe in both, but they really don't want them going to that limit.

My temp is constantly 35+ btw for those of you wondering, I have 90 841s Title: Re: Avalon 8 official specs released Post by: Didley1JT on April 28, 2018, 01:49:56 AM I'm finally back!
Just moved my family from Louisiana to the Pacific Northwest. It's so much better here. And electricity is almost two cents per kW-hr cheaper! They have a three tier power rate here that starts at $.07361 and then tops out at $.08118. Had the electrician come out and start me with two 30A/240V circuits. Currently running the two Avalon 821s I bought from the first batch (finally). At the 0 voltage setting, they're sitting at 11.5TH/s and 11.6TH/s and both are at 30deg Celsius. Next step is to take advantage of the heated air to help heat the house when it's cold. Kind of bad timing as we head into summer, but at least I'll be ready for the fall/winter this year. Title: Re: Avalon 8 official specs released Post by: philipma1957 on April 29, 2018, 08:04:58 PM Well my testing shows intake temps cause large power increase.
67f=1365 watts 76f=1424 watts 81f=1484 watts I was able to get same results with 2 different psus And on 2 different pools. I want to do an 86f room test next Then a 91f Title: Re: Avalon 8 official specs released Post by: ccgllc on April 29, 2018, 10:23:19 PM I sent an email to Steven, let's see if they have some lab test info or etc. which could help to specify the A841 technical specs more accurately.

Title: Re: Avalon 8 official specs released Post by: philipma1957 on April 30, 2018, 12:04:07 AM I was able to do what I consider a quite remarkable video
Setting the stage for this youtube video I turned on a lot of gear in my garage to get it to 87f which is 1 f higher then the 30c or 86c number used. I did it real time it was 55f outdoors of my garage and my garage was 87f. I opened the two garage doors and the back door to cool off the garage watch the watts drop in real time Your video will be live at: https://youtu.be/KEctJaz4Mo0 what does this mean? My opinion is summer will not work well if you plan to fan cool this miner. Title: Re: Avalon 8 official specs released Post by: taserz on April 30, 2018, 08:02:40 AM I suggest trying to pickup one of those atic gable fans for your garage or solar array it will really help with moving air out of the place just be sure you are also getting enough air coming in. (Edit: I might have 1 for sale actually ran it 24/7 for like 3-4 months. No longer need the second one since I have 95% of my miners in a facility near by)
Title: Re: Avalon 8 official specs released Post by: PeaMine on April 30, 2018, 10:34:31 PM Well my testing shows intake temps cause large power increase. 67f=1365 watts 76f=1424 watts 81f=1484 watts I was able to get same results with 2 different psus And on 2 different pools. I want to do an 86f room test next Then a 91f Thanks for this, I noticed this as well even with my 741s, though it wasn't as extreme. I even kept the PSU at 25C by building a mini insulated AC rack out of Rigid Insulation, air filters and a portable AC unit. The S9 and S7 don't seem to have this issue, which seems to make the A841 more efficient in lower temperatures only. Once summer gets closer, this will most likely be a hot issue. I sent an email to Steven, let's see if they have some lab test info or etc. which could help to specify the A841 technical specs more accurately. Hi HagssFIN - Been a week now... have you heard anything back from Steven? Was curious about this as well. There hasn't been a single post in the Blokforge thread since the 21st and Minerwarez since March. I miss being able to buy from and recommend Canaan over Bitmain, so hopefully this can be resolved soon.

Have found a solid under clock thanks to megaquake . see youtube above. this makes the miner viable if you are not mining in the tropics i.e. constant 80f temps will hurt miner all year round. I am in NJ USA 7 cooler months means it is better then spec for those 7 cooler months. 5 warmer months it is worse then spec. avg out to a little better then spec. if you are in Finland and air cool it should be fine.

Title: Re: Avalon 8 official specs released Post by: ccgllc on May 01, 2018, 01:50:25 AM Now that our early spring temps are gone, and with the downgrade of the specs on Avalon 8s, I've been paying close attention to the reported temps my machines are running at.
I have (3) AUC3s full: 10 on a lower shelf (5 with APW3++s and 5 with Sorcerer PSUs) and 5 on a shelf above those with APW3++ power supplies For some reason, unit #7 on the lower shelf is running 4C hotter than all the others. I checked, nothing is blocking the intake or exhaust. Any ideas? Oh. FWIW, I just separated my Sorcerer PSUs and put about 2 inches between them and the their 841s. Noticed those puppies are hot! Figured if nothing else it would help mix their exhaust air with room air a bit. Title: Re: Avalon 8 official specs released Post by: ccgllc on May 01, 2018, 11:21:59 PM How did you do that? Because if you just selected -1 in the web UI, that didn't make the change, you have to add the "--avalon8-voltage-level-offset -1" string in the more options line in the configuration the 0 - zero option is hard coded no matter if you selected the -1, -2, etc or not. :)... little known detail. BTW, from 0 to -1 on mine will show an approx .150-.2 Th drop per miner in the rate, but the outlet temp will change by a couple of C too Finally got around to adding this line. Seeing very similar results, e.g. No substantial change. I'm a bit confused though, when I look in the process list I now see: Code: cgminer --lowmem --avalon8-fan 10-100 --avalon8-voltage-level-offset 0 -o stratum+tcp://stratum.kano.is:3333 -O ccgllc.Pi3a:pass -o stratum+tcp://stratum.slushpool.com:3333 -O ccgllc.Pi3a:1234 -o stratum+tcp://profit.pool.bitcoin.com:3333 -O ccgllc.Pi3a:X --api-allow W:172.16.4.0/22,W:127.0.0.1/32 --api-listen --avalon8-voltage-level-offset -1 --real-quiet I'm presuming the first instance of offset is hard coded and hopefully being overwritten by the second instance? Title: Re: Avalon 8 official specs released Post by: HagssFIN on May 01, 2018, 11:31:02 PM @ccgllc
Yes, it gets overwritten by the second instance which you have inserted in the 'More Options' field. Title: Re: Avalon 8 official specs released Post by: PeaMine on May 04, 2018, 01:53:14 PM Not sure why Canaan didn't post here as well about this, but a partial explanation on why the operating temperature range was changed to 30C from 40C
https://bitcointalk.org/index.php?topic=3375954.msg36259525#msg36259525 In which case it would be wise to mention this on the official specifications and send out an email to clients who might be affected, explaining this intent. Now that the weather is starting to stay over 30C I am seeing a 6.5% drop in efficiency already and it is still Spring, even with -2 selected for voltage offset. Without the -2 voltage offset, they get way too hot and reboot themselves frequently. Summer is going to be interesting. Title: Re: Avalon 8 official specs released Post by: fccs on May 04, 2018, 10:28:52 PM Yea the majority of places in the USA will hit temps above 30c during summer at least a few times. Mine have been doing ok so far and even with the temps being about 90f the last recent day, my airflow in my location is good enough that the machines didn't shut down or restart once. (Although probably came close to it at the 100-103 mark)
Title: Re: Avalon 8 official specs released Post by: ccgllc on May 08, 2018, 02:41:38 AM Just noticed that Canaan slashed the prices of Q60 841s to $1120.
Nice to see them competing with the "new" Bitmain S9+. Title: Re: Avalon 8 official specs released Post by: PeaMine on May 11, 2018, 01:09:59 AM Anyone else having issues with their 821 and 841 now that it has warmed up a bit?
It's around 36C, which was the operating range when I purchased these, and some are able to handle it, but many are restarting every hour or so and hashrate has dropped around 8% lower on the miner status screen and around 14% lower on the pool. However power usage has not decreased. I highly doubt these will survive summer or be able to operate. Sometimes they completely disappear from the controller but still seem to be using power but producing nothing. Is there a way to fix this? Due to all the restarts and possibly bad boards I'm currently averaging 8100GH per 821 I powered off my 841 for now while I wait on a reply from support as it was unable to stay online for more than a few minutes. Title: Re: Avalon 8 official specs released Post by: ccgllc on May 11, 2018, 03:50:43 PM So far I've only lost (1) APW3++ power supply - a fairly new one (weeks old). Might have been to heat, might not, but the Avalons are hanging in there. I am running with option:
--avalon8-voltage-level-offset -1 Which is reported to help with heat at the cost of a small bit of performance. Title: Re: Avalon 8 official specs released Post by: frodocooper on May 12, 2018, 04:04:29 AM Looks like Canaan are looking to revert the A8's target temperature back to 90°C, according to commit ae73ff0 (https://github.com/Canaan-Creative/cgminer/commit/ae73ff0e044e6a7882095dff8e509fa8ebbd8423) in the avalon8-dev (https://github.com/Canaan-Creative/cgminer/tree/avalon8-dev) branch of their cgminer repository.

Title: Re: Avalon 8 official specs released Post by: ccgllc on May 12, 2018, 04:16:32 PM I'm having a little weirdness in one of my strings of 841s:
It is configured with (3) AUC3 each with (5) 841s all running the latest MM code. Over the past couple of weeks, occasionally I see an individual miner drop ~1/3rd of its hashrate. Rebooting that unit clears that up. This morning, I had an entire string behind an AUC3 drop 1/3rd of its hashrate. Five boxes, all at once. Rebooting cleared them, but does anybody know what might be going on? Title: Re: Avalon 8 official specs released Post by: HagssFIN on May 12, 2018, 04:18:34 PM @ccgllc
Does using a different AUC3 converter dongle in that chain make any difference? Title: Re: Avalon 8 official specs released Post by: ccgllc on May 12, 2018, 04:27:42 PM @ccgllc Does using a different AUC3 converter dongle in that chain make any difference? Should state that I still consider myself a newbie with Avalons, only having had them a couple of months now. So far, loss of the entire chain has been a one time thing. If its consistent, I'll try swapping out the AUC3 (have a couple of spares and more coming next week).

OpenWrt firmware AvalonMiner 821: https://canaan.io/downloads/software/avalon821/openwrt/20181128/ AvalonMiner 841: https://canaan.io/downloads/software/avalon841/openwrt/20181128/ AvalonMiner 851: https://canaan.io/downloads/software/avalon851/openwrt/20181126/ MM firmware AvalonMiner 821: https://canaan.io/downloads/software/avalon821/mm/2018-11-26/ AvalonMiner 841: https://canaan.io/downloads/software/avalon841/mm/2018-11-26/ AvalonMiner 851: https://canaan.io/downloads/software/avalon851/mm/2018-11-26/ There is no changelog for the OpenWrt firmware at the time of writing. The changelog for the MM firmware simply states "support for low power." Anyone report any changes to hashrate w/ the new firmware? Despite Bitmain using "Low Power Mode" as code for ASICBoost, Canaan's latest firmware is just voltage optimizations, correct? Title: Re: Avalon 8 official specs released Post by: mgoz on December 01, 2018, 04:00:04 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.
Title: Re: Avalon 8 official specs released Post by: frodocooper on December 01, 2018, 09:16:01 PM 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.
Title: Re: Avalon 8 official specs released Post by: Steamtyme on December 01, 2018, 09:23:38 PM I like those numbers especially considering this isn't gear I'd have to order.
Did you happen to run any of them without the offset just to see what they draw for a baseline after upgrading? Title: Re: Avalon 8 official specs released Post by: frodocooper on December 01, 2018, 09:27:30 PM I like those numbers especially considering this isn't gear I'd have to order. Did you happen to run any of them without the offset just to see what they draw for a baseline after upgrading? No. All of them are at a colocation datacenter, and I instructed my service provider to run them with the offset from the get-go. I don't have remote access to the miners. Title: Re: Avalon 8 official specs released Post by: gvb on December 04, 2018, 09:01:06 PM I see above that the speed drops about 20-25% with the new firmware and the same voltage setting.
Can we really call this efficiency improvement? I would expect less Watt while keeping the same speed. It makes sense that less speed would mean less Watt. It seems more like they used the voltage values of -3 or -4 for -2 now. Thank you, i thought there was a way, to upgrade the working system. I don't want to re flash sd card. you can do an inplace upgrade of the controller. System > Backup/Flash > Flash new firmware > [ x ] keep settings Title: Re: Avalon 8 official specs released Post by: minefarmbuy on December 05, 2018, 05:05:56 AM Welp, upgrading my 821 finally. :)
Edit for update. Well so far no real noticeable change, hash is the same as it was at -2 but temps are lower and fan speed is reduced obviously. Title: Re: Avalon 8 official specs released Post by: gvb on December 05, 2018, 12:56:17 PM 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... 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. :( Title: Re: Avalon 8 official specs released Post by: minefarmbuy on December 05, 2018, 03:14:44 PM 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. Title: Re: Avalon 8 official specs released Post by: gvb on December 05, 2018, 03:35:46 PM 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. Title: Re: Avalon 8 official specs released Post by: minefarmbuy on December 05, 2018, 03:42:30 PM 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. Title: Re: Avalon 8 official specs released Post by: W15ER69 on December 05, 2018, 04:31:09 PM System > Backup/Flash > Flash new firmware > [ x ] keep settings What file i must to flash?

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

Make sure you downloaded from the 20181128 (https://canaan.io/downloads/software/avalon821/openwrt/20181128/) (OpenWrt) and 2018-11-26 (https://canaan.io/downloads/software/avalon821/mm/2018-11-26/) (MM) directories.

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.

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. Title: Re: Avalon 8 official specs released Post by: mgoz on December 06, 2018, 07:55:52 PM 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.

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 (https://bitcointalk.org/index.php?topic=5045732.0). 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? Title: Re: Avalon 8 official specs released Post by: frodocooper on December 07, 2018, 10:22:24 AM [...] 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. Title: Re: Avalon 8 official specs released Post by: notabeliever on December 16, 2018, 12:30:17 AM 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. Title: Re: Avalon 8 official specs released Post by: Steamtyme on December 20, 2018, 03:34:46 PM 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. Title: Re: Avalon 8 official specs released Post by: gvb on December 23, 2018, 01:41:19 AM 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. Title: Re: Avalon 8 official specs released Post by: frodocooper on December 25, 2018, 01:17:00 AM Canaan has released new OpenWrt and MM firmware for the 821, 841, and 851.

Title: Re: Avalon 8 official specs released Post by: HagssFIN on December 25, 2018, 09:26:16 AM 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. Link: https://www.eastshore.xyz/review-for-canaan-mining-heater/ Title: Re: Avalon 8 official specs released Post by: Steamtyme on December 25, 2018, 01:42:12 PM 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. Title: Re: Avalon 8 official specs released Post by: HagssFIN on December 25, 2018, 02:05:03 PM As it is a 8 series miner, maybe there will be a low power firmware available for this model as well. :)
Title: Re: Avalon 8 official specs released Post by: leowonderful on December 25, 2018, 03:37:27 PM 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.

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.

There are no published changelogs for each miner's 20190404 OpenWrt release at the time of writing. The published changelogs for each miner's 2019-04-04 MM release are identical to each other. Here is the changelog for the A851's MM release: Code: Version 8511904-1ab9760 The publication of these OpenWrt and MM releases correspond to Canaan's addition of new commits on April 4, 2019 to the avalon8 (https://github.com/Canaan-Creative/cgminer/tree/avalon8) branch of their cgminer repository (https://github.com/Canaan-Creative/cgminer). The most noteworthy of the new commits is commit b2356a1 (https://github.com/Canaan-Creative/cgminer/commit/b2356a172b71636a51c0136bb8ac8333307d82ba), which adds user-selectable power modes. The new modes are set by the --avalon8-power-mode (https://github.com/Canaan-Creative/cgminer/blob/b2356a172b71636a51c0136bb8ac8333307d82ba/cgminer.c#L1604) command-line option, with values ranging from 0 to 5: Code: OPT_WITH_ARG("--avalon8-power-mode",Values 3 to 5 appear to be unassigned as of this commit.

Title: Re: Avalon 8 official specs released Post by: PassThePopcorn on April 05, 2019, 06:25:55 PM This seems to be one of the better firmware releases recently. Only tested on 851's.
There only seems to be a few issues with this, the power consumption in the "higher" mode is on the verge of 1900watts @ 15th/s the June release was more around 1700-1800w @ 15th/s. Balanced seems to give around 13th @ 1400-1500w Low power is around 9th @ 900w Trying one of their advanced cgminer-api commands and using their cgminer-monitor bash script there is an issue with cgminer restarting over and over (this is only if you use an advanced command and is fine if you aren't using that specific command), I made a work around bash script that fixed this and will send it to Avalon for them to clean it up as I macgyvered it to make it work as intended. The api frequency adjustment works properly in this release as well, instead of using the more options on the configuration section. Now using the June release you can get similar results for power consumption / efficiency by manually changing the frequency and voltages in the cgminer config, but for a novice that wanted to use the lower power mode or if you want any of their more advanced commands this release would be "better". If you were a novice and just were going to use this in normal operational / high efficiency I would just use the latest June release to have a lower power footprint. Also gave you some merit as I wasn't aware of an April release, my previous tests were on March and February. This release also fixed two miners that the March release broke. Title: Re: Avalon 8 official specs released Post by: minefarmbuy on April 25, 2019, 05:56:51 PM Going to update my 821's at some point today. Best to update controller then units?
Title: Re: Avalon 8 official specs released Post by: HagssFIN on April 25, 2019, 06:45:26 PM @minefarmbuy
Yup, that's the way I do it. Title: Re: Avalon 8 official specs released Post by: mgoz on April 25, 2019, 07:25:43 PM This firmware is good if you want to be able to easily switch between regular and low power mode. I installed when it came out and will be shutting down all 8 series today and replacing with S17. With the original low power firmware I was able to have 821 and 841 units on the same controller. With this firmware, I had to put them on their own controllers as the 821 wouldn't show up on 841 controller. No I did not attempt to flash the MM firmware with them all daisy chained and upgraded them individually. There is a bigger hash rate drop on the 841 than the 821. Both will hash around 9 TH/s.
Title: Re: Avalon 8 official specs released Post by: minefarmbuy on April 26, 2019, 04:10:29 PM So far on LPM, -2 offset getting 17th/s at 1500w with two 821's fan pretty quiet under 35-50%. HPM , +1 was hitting 23th/s but pushing 2700w, I didn't leave it there long before swapping to LPM. Over night getting 17.2th/s from UI, and 16.8th/s pool side at about 1450w. Title: Re: Avalon 8 official specs released Post by: NotFuzzyWarm on April 26, 2019, 06:58:11 PM Over night getting 17.2th/s from UI, and 16.8th/s pool side at about 1450w. 8) With good speeds and being fairly quiet looks like I may be able to replace the 2x throttled down 721's I have running in our inspection room with 2x LPM 821's and gain around 7THs at the same time :) Title: Re: Avalon 8 official specs released Post by: minefarmbuy on April 26, 2019, 08:50:42 PM Yea, really happy with the new fw. Been mining at a loss with my power rate and now that was cut in half. Let me know if you want to look at a live stream.
Title: Re: Avalon 8 official specs released Post by: notabeliever on May 16, 2019, 01:56:17 PM Just updated one miner with new MM firmware 2019-4-30. Working good for anyone wishing to update their miner. Left my RPI controller alone Avalon Firmware for avalon8 - 20181123.
Also working on 1200 w psu. Code: --avalon8-voltage-level 5 --suggest-diff 65532 Fine just second miner needed more power Title: Re: Avalon 8 official specs released Post by: NotFuzzyWarm on May 16, 2019, 02:22:24 PM As an FYI, unless you have a very specific reason for setting diff it is almost always best to let the pool decide what diff is used by your miner(s).
Title: Re: Avalon 8 official specs released Post by: PassThePopcorn on May 16, 2019, 03:12:46 PM As an FYI, unless you have a very specific reason for setting diff it is almost always best to let the pool decide what diff is used by your miner(s). There is a reason, if you have a full rpi the pool will provide a difficulty based on the total hashrate being submitted by the pi. Each individual miner's optimal difficulty is much lower than that. While in the end the hashrate should equal out, you'll see some drastic spikes on the pool. Setting a manual difficulty that matches each miners hashrate has keep the pool graph as a nice straight line, it also helps when monitoring units as they don't have any huge jumps in either direction. Title: Re: Avalon 8 official specs released Post by: NotFuzzyWarm on May 16, 2019, 03:26:34 PM And each A8 has an optimal diff far lower than 65k. The single 841's I have running in various locations have a diff of between 7.5k and 8k. What the pool cares about is shares-per-minute and they want to keep the I/O bandwidth low as possible. At Kanopool the target is 18SPM. Sending many more (lower value) SPM than is needed just uses more resources at the pool end while giving the same end result.

That's true, however when monitoring multiple PH seeing a drop of 500+TH when the pool changes blocks and you get all the current work/shares dropped and they are at a difficulty of 300k, the smooth line is better. Our reject rate has dropped substantially after lowering the difficulty and setting it on a per miner rather than per controller basis. Title: Re: Avalon 8 official specs released Post by: notabeliever on May 17, 2019, 01:21:03 AM The Diff is their to help when renting.
To clarify my post above I have one 841 that likes to run on a 1200watt psu however my second 841 does not like it has it needs more power so I have confirmed MM 2019-04-30 is working. I ran one side on the psu and works. My next task will be to operate a RPI- controller using the new firmware for that Title: Re: Avalon 8 official specs released Post by: bg17aw on February 14, 2021, 08:52:04 PM @minefarmbuy Yup, that's the way I do it. Is there a reason why? I am trying to understand how to update my 841. I see here https://download.canaan-creative.com/ there are 3 different types of firmware - MM - how to update this? - OpenWRT - this is just a matter of writing a new microSD card, right? - PMU - what is this one? it is from 2020 so fairly recent Also there is one called Nicehash, what is that all about? I am already mining on Nicehash pool and working, although I did not update ever. However, I know there is a new algo called AsicBoost, and if I select AsicBoost pool on nicehash, my 841 miners will not work anymore. Would this update solve the AsicBoost problem? Title: Re: Avalon 8 official specs released Post by: NotFuzzyWarm on February 15, 2021, 02:18:26 PM MM is the actual miner firmware.
OpenWRT is the miner controller software. PMU is for the power managment unit (where the PCIe plugs are) Just make sure the MM and OpenWRT are from the same release dates, they are matched pairs. For OpenWRT open GUI and go to System > Backup/flash firmware to start things. By doing the upgrade from here you have the option to retain your pool & users settings. Um, if you have not done it yet, this would be a good time to backup the miner settings... For the MM, after doing the OpenWRT and rebooting controller, open GUI and go to Status > MM upgrade and again do the obvious. Can't say I've needed or used the PMU update, read the README for what it is about and how to apply if you want to use it. AB is *not* a new algorithm, it is a hardware-based way to generate additional work for the miner to process and requires the miner chips to support it. AFAIK the 841 only supports AB when in Performance mode. Title: Re: Avalon 8 official specs released Post by: bg17aw on February 15, 2021, 07:57:31 PM Thanks a lot for the detailed answer.
How to switch them to Performance mode? They are now doing 13,5Gh on the original firmware. [Firmware version] => Avalon Firmware - 20180305 I was hoping that someone who already updated to Nicehas firmware would share the results. I guess I will try for myself, and report back. I realize there might not be a lot of interest in this model anymore, but hey, it might help someone. Right now, on the original firmware, when using an AsicBoost pool, the miners behave very strange, and basically do not work. They keep on turning the fans down for a second and restarting (sorry, not sure if they are actually rebooting). Title: Re: Avalon 8 official specs released Post by: NotFuzzyWarm on February 16, 2021, 05:28:16 PM 1. Nicehash or any other mining rental service is a terrible idea to use. Sure they pay you but it is a fraction of what they earn from your gear. Join a PPS pool - you will earn more.
2. I assume you are talking about Nicehash's AB pool? It sux big time to the point of needing the special driver that Canaan made to run their miners there along with NH having a dedicated AB connection address. The Avalons all work fine on non-rental pools and all pools these days will run AB if the miner can do it - no special driver or connection required.

What pool would you recomend? viaBTC takes a very large commission on withdrawals. Minerstats says Nicehash is one of the most profitable (sometimes the most profitable of all!): https://minerstat.com/hardware/aisen-a1-24t. 2. I assume you are talking about Nicehash's AB pool?

Yes, Nicehash's AB pool, when changing pool to stratum+tcp://sha256asicboost.eu.nicehash.com:3368, the miners just stop. Strangely, I tried to mine on Nicehash pool using an Asien A1 miner, well, this one refused to start on Nicehash normal pool, but works just fine on Nicehash AsicBoost pool! Just make sure the MM and OpenWRT are from the same release dates, they are matched pairs. They are not all from the same release dates, there are some OpenWRT images that do not have a correspondent in the MM directory. Also, there is a folder called Nicehash in OpenWRT but no MM nicehash folder: https://download.canaan-creative.com/avalon841/openwrt/ EDIT: Success, I updated the miners to [Firmware Version] => Avalon Firmware for avalon8 - 20190711. OpenWRT version is called Nicehash, this seems to work very well. MM updated to latest as well. Not sure how to update PMU, if anyone has any idea about this, I would be grateful. After the upgrade, miners do seem to consume about 100w less and the hashing speed seems a bit higher. For 4 miners, it used to be about 54,xx, now it is 55,15. Overall happy. |
