Getting the A1041 from Buysolar for a review and demo

I'm expecting to grab one in about a week. We'll be putting together a YouTube video along with a setup review. I'll check back in here soon. Feel free to chime in. A1041 Corrected to a1041 First video here: https://www.youtube.com/watch?v=vyQWSx8XL40 Second video here: https://www.youtube.com/watch?v=btdHHbfSJ84 I'll make more once I receive the second unit from Buysolar's place. Edit: here's the third video Your video is going live at: https://youtu.be/jB0nkD7RcqU And the fourth video is here: https://youtu.be/iZCEtbMz3vw

Spacer.  I put all questions and posts here in the spacer post.

We got tracking for these today.  May show by Friday the 28th of June. A lot has happened Since I started this thread BTC is over 10.5k! It was 8.7k when this thread started. from canaan website Specs are: order link below https://canaan.io/product/avalonminer-1041-august/ I blue bolded the most interesting feature of the new gear. No one else does this. If the eth cable linking works well this will be a knock out product. The savings on switches for a 50 rig setup. Shorter eth cable runs. Buysolar and I will each get one of these units We will run them apart. We will then link them via eth cable. Assuming it works as expected we will order at least 10 of them. I want to thank Steve and Lily for sending demos.

Psu should also be built in. I am really excited about the eth daisy chain of these units. I have no idea if they can do 254 but if they can do 40 well it is good enough . With our Warren super build cancelled> We lost bid for the 140 acre property. Warehouse owner and partner with buysolar and I Have switched and are going to plan 'b' We will expand power at the current set of warehouses from:   65k-watt to 175 k-watt  build out. Then expand again from 175k-watt to 475k-watt. Solar will cover the first 90kwatts.  the rest will be at 5 cents. The expansion from 65kwatt to 175kwatt is done on the power side. We have 23kwatts of gear to put in now. So by next monday will will have 88kwatts running and 87kwatts to fill. These new avalons figure heavy for us. they are pretty dense at 36.9th and we won't need anymore switches if the eth daisy chaining works. Are they the most efficient gear no they are not. But no switches needed saves $$$ Short cheap eth cables saves mess and $$$ If they are as reliable as the A921 or the A721's  the 130 mile round trip to fix gear will be reduced greatly. We were up in Clifton last thursday cleaning all gear with an air hose. After 8 hours we did ⅔ of the gear and have ⅓ to clean. The l3+ units still need to be cleaned 25 of them. We did 25-30 s-9's we did        8 m-10's we did        1 s-17 we did        1 s-15 we did        1 t-15 we did        1 l-3+ we did        1 t2t24th all of the above  stone cold dusty nasty dirty and all of the above slow to clean we also cleaned  our avalon gear 1 a921 2 a721 all three noticeably cleaner inside due to fin designs. all three faster to clean we have had about 7 months of mining in Clifton and the 3 avalons never dropped out or stopped mining every other company's gear dropped out at least once. for us that could mean a  six week time between maintenance trips to Clifton not 3 week trips. so 8 or 9 rides to Clifton vs 17 or 18 rides to Clifton Two Guys me and buysolar to do the maintenance . this is a big savings for us. maybe 130 x 10 = 1300 miles  6 x 10   =     60 in tolls 16 x 10 =    160 work hours 2 or 3 switches lots of eth wire at 2/3 foot vs 10 foot. 1 router could do  10,000 units  with only two 24 port switches 218 units per port  218 x 23 = 5014 units per 24 port switch. Realistically for us if we go all avalon on the next 87kwatts we get  35 units do 7 per port use 5 ports. it works fine.

Avalons are a beast when it comes to reliability, I've never had a real issue with one. It's been a shame they haven't been able to come out ahead of everyone else on an efficiency launch. I think it's been a huge step getting rid of the external controller then following up with the Eth daisy chaining keeps them unique and easy to network. All the benefits without the potential points of failure.  I wonder if these will still be able to operate as 1 worker for all linked chains or if they will now be individual workers. It didn't even dawn on me the switch savings, I'm lucky enough that I'm still small and can get away with a couple home routers networked together to meet my needs and boost the home wifi network.

I was always able to use one 24 port switch But the clifton build changed my world of mining. we are using 70 units two 24 port switches one 48 port switch three routers modem to one with 192.168.1.1 for all non-mining gear to two mining routers one with 192.168.0.1 for all sha gear uses 24 port and 48 port about 40 pieces one with 192.168.10.1 for the L3+ uses 24 port about 22 pieces the setup above could do  say 240 + 250 + 250 = 740 miners  you would many many many switches I guess 30+ 24 port or 15 plus 48 port. but if we push avalon we could do 1000's of them with no extra switches. realistically add the 87kwatts use 35-40 avalon then if we do 400 more use 150 avalon  not a single extra switch.

Okay the miner arrived but not the psu. Disappointed mostly seems to be fault of DHL gear was due thur. it is fri. 2 boxes one for miner came today box with psu is floating about buysolar is getting a set of 2 boxes like I am in his case neither box has arrived here is youtube video of opening of miner box Your video will be live at: https://youtu.be/vyQWSx8XL40 Published  you can see it full size image https://i.imgur.com/nAOQnDA.png

It has arrived. Unlike the other review I have been given a stand alone psu with cables.  What does this mean it means  I had to take off the controller case to see the buss bars as they are not marked pos or neg. The psu did show pos and neg so I was able to correctly wire the gear. A relief for sure. It is not that loud it can be sound proofed with the psu I was given from them. I have it set to normal  and I am around 29th and 2060 watts.  That is better then the m10 not as good as the m20s. from whatsminer.  It is  pretty well made I will need to give in my case examples vs pass the popcorns note the clean built in psu with buss barr attached on passthepopcorn's gear. and the loose psu hook up worse  then that is the miner buss barr screws are not marked I removed the controller lid and could see the - + markings. thus hook up was okay close to 29th at the pool.  and 2050 watts  that is  2050/29th on low speed 70.6 watts a th my m10s would do 2250/31th on high speed 72.5 watts a th

volts at 230.6 watts at 2061 we will not be fully solar here this site has 5/6 cent power deal. as of now we plan 90kwatts of solar 85kwatts of paid power. cost say 3-3.5 cents net for 175 kwatts this is 126000 monthly kwatts at 3.5 = 4410 USD a month bill we could add 300kwatts more of 5/6 cent power but that is for 2020 or dec 2019 she seemed to settle in at 31.5 th and 2055 watts or 65.8 watts a th. so if we were all avalon a1041 we would have 83 of them doing 31.5 th or 2.61 ph earning 2.5 coins a month   which is why gear is  selling like water in a desert. we have gear and do not have the room for 83 of these but depending on the next set of tests, which will be the ethernet cord daisy chaining. We are looking at getting 10 of them. My assumption is the we all go to built in psu with buss bars. and not the loose style I am testing today. I also assume more pools and more features in the GUI. As mine is exactly the same as passthepopcorn. next test is high speed so far it pulls 2650 vs 2050 watts it hashes at 36.9 vs 31.0 th so 71.8 watts a th I will let it settle more. normal 2050 watts 30.8-31.0 th  this was about 1 hour 20 minute test. 66.12 watts a th turbo   2640 watts 34.9-37.1 th  about 1 hour and change   71.16 watts a th So beta psu and beta software   it looks good  but not great Still with todays prices this gear is a moneymaker. biggest quirk was it did not run well on mmpool.org a small btc mining pool. What is it worth? good question Hard to tell with the beta psu  I would not rush to buy it. I do assume Steve of canaan will post on the psu as I prefer the attached style over this loose beta model.

I thought they were supposed to be 1736W @ 31TH?

maybe they are maybe not as the psu I have could simply be a 88% psu. I am posting a video in a minute you can see this is clearly in beta status. Your video will be live at: https://youtu.be/btdHHbfSJ84 the above will take time maybe 10 more minutes to load. this demo does not have the same psu setup as passthepopcorn's unit had. I have multiple meters and will clock this gear  very closely.  the rooms temp is 30c or 86f the rating of 1736 watts is for 20c or 68f

Thanks for keeping us up to date Phil, as you said there isn't much hardware around at the moment.

Lets say once fully tweaked it is 60 watts a th for the 31th setting not 56 and it is 68 watts a th for the 37.2 setting not  65th. at current prices it is viable gear. it does not need many switches if it allows 100 or more for a daisy chain. It Steve said to me he could send me ten this weekend I would take them with  the loose sloppy psu setup and wait on the buss bar psu's Avalon is reliable gear for me so far. eth daisy chaining seems like a good idea. I will drive to buysolars house and bring his to my house and setup a 2 unit daisy chain. Should video it on sat.

Even with these its getting harder. Blokforge has upped the price of the August batch to $2300, September sold out, so October is the earliest at reasonable prices. Canaan has some September left, but August all sold out. As I'm not shipping to the US I'd probably choose to get them from Canaan direct.

Ran it over night  does about 11 amps or 11 x 230 = 2530-2600 watts  and about 37.05 th  so 37.05/2530 = 68.29 watts to 70.17 watts on high speed. Second unit was picked up from buysolar. I have both running at normal speed they do around 30-31 th at 2016-2015 watts so 61 th at 4031 watts on normal speed. both have loose style psu. and basic demo/beta gui. eth daisy chain does not seem to work, but I will fuck with it some more. so I have 2 ports 2 ip's at the moment.

Found out how to hook up daisy chain

Honestly though Phil, saying that the 254 address limit is bad is pretty nit picking, it’s a limitation with IP addressing and not the miner. The IP range limits are present in most miners outside of canaans due to their independent controllers . I think daisy chains are a brilliant idea that would help reduce clutter and cost, it would be even better if it had ring type topology to help with redundancy, can you test this Phil? Meaning the second miner goes back to the router and if any one cable is unplugged the miners still are connected. doesn’t IP address ranges end at 255?

255 is typically reserved for broadcast and 1 is usually for a gateway depending on your setup. The range is 1-254. To your question on the daisy chain I believe this answers it @Phil instead of getting a router and setting it like that what about a pfsense box, operates as a router. While I wouldn't suggest it, on your current one you should be able to change the subnet from 24 to 16 and increase your available IP's. It depends on  your setup but if you can change it to 16 you would be able to run machines on 192.168.x.x instead of 192.168.10.x. Most big mines can run tens of thousands of machines off one firewall, they don't typically go to a /16 but a /24 with a change in octet 3 for groups of units.

I am just getting bigger now. I know about subnets but in a classroom 10-15 years ago. Real world 150 miners is most I have done in one spot. the modem is verizon the router is verizon.  belong to the warehouse owner. so a 5 port switch to my 2 routers was cheap enough and my 2 routers were also cheap. my third router will also be cheap. so being isolated from the owners gear still gives me an easy 750 miners which is not happening. I do have to say have a different ip for the avalons in my case is good and not an issue. It is pretty much good and allows easy access teach one. up to 250 or 254 then things get more complex.  So is bad the right word maybe not . That ring idea is good I will check it later.

Ring idea makes a loop and crashes the net completely. This has happened to me when I do a lot of eth switch work and make a mistake causing a loop on a switch. So for now the loop idea is out. I want 10 of these as soon as I can get the ten. If I get that many I will do extensive tests of eth cables. Chain of all cat 5 Chain of all cat 5e Chain of all cat 6 Chain of all cat 7 I will measure hashrate on all 10 units with each set of ten cables As we all know most of the time cat 5 or cat 5e are fine. But with ten cables linking cat 6 or cat 7 may be better. It will be interesting to see if A. Gear is stable in a ten unit setup. B. Gear hashes lower with cat 5 C. Gear  hash descends as link grows. D. Gear hash is improved with cat 7. Ten unit test should be enough to help people decide if they want the gear. And how long to try to make the chains.
