Avalon A1041 Review

[NotFuzzyWarm]

There really should be no difference in PSU efficiency. If anything, the PSU case looks physically larger which *could* imply it will run a bit cooler since should have better airflow and that often gives a tad bit more efficiency. Heavy gauge cables vs bus bars should be moot.

[minefarmbuy]

I was under the impression the integrated psu was for more efficiency. I really doubt Canaan will be sending out gear that will go lame on you anyway.

[Blokforge]

let us know how these work.  @ blokforge do these units have the premounted psu.

the beta ones I got have a loose psu.  gospower is the name.

These are the same, gospower, but you can still consider them integrated since they do have the additional cables between psu and miner, for regulation,  they are just not mounted to side of unit due to size.  They are solid units, considering all the failures we heard of with the S17 psu's thus far, i would be more comfortable with these regardless.

please send me a link for it.  better yet post it here.

This is a nice cheap way for loopback detection / prevention, it worked out of the box disabling the port. I haven't actually done any tests other than both ends are now connected and everything is chugging away nicely.

Immediately after turning off the first system in the chain the switch detected the first port was down and reactivated the deactivated port it appeared there was little to no delay in mining as by the time I got to the computer everything was still running.

Of all the gear tested the Avalon  a1041 with the larger psu and this larger fan was the best to run at low speed. It was due to the unattached psu. If I were to use 5 more units. I would have zero issues with the loose psu.  I got 31th at lower speed setting and it was pretty quiet. Makes it good for a home miner.

Thank you for your feedback and tests results, worth it.

I'm looking for quiet miner , the A1041 is a good candidate but I didn't pull the trigger on it yet.
I had mining issues at ProHashing.com ( Multipool ) and at dgb-sha.theblocksfactory.com ( DGB Mining / SHA256 )  with the A721.
The A721 was dropping / reject a lot of hashrate. Digibyte blocks are release at 15sec pace. The Avalon's didn't like it.
No issues with the ant's ( S7 / S9 / S15 )

I would be interested to see tests results if someone could try those 2 pools with the a1041 and report back.
Thanks !

@ qctechno_isback

my machines are in Clifton NJ about a 90 minute car ride.  And I won't be going up there for a week or so.

Also this is an alt coin question,so I would suggest pm'ing  a few guys to see if they will test for you.

well  it is quieter on the lower speed setting then the bitmain s17 is on the lower speed setting.

I would say it is a decent home miner due to that.

my quietist new gear is the m21s on low speed  but 29th  is way lower then the high speed setting's 56th

the a1041 is 31th on lower setting vs 37th on higher setting.

So if you are a home miner  a few  a1041's on low speed  should work sound wise due to the fatter gospower psu

and dropping to the low speed you don't lose a lot of the 37 drops to 31.

Did anyone receive the shipment from Blokforge?

Has the efficiency really gone from 2.7 kw to 2.089 kw for the 37 TH mode with the update in the firmware?

Well that would be nice if true.

I wonder what efficiency is for 31th setting.

1st bath is now shipping today.

After getting devs to work out another DNS bug last night that was reverting DNS to mainland china address causing lockup, units are solid now, reflashing all of them.  Also added tool to upgrade firmware within the web portal so does not have to be done with command line any longer as that would have made people lose their mind.

average seems to be 37TH/s@2098W in performance and 32.4TH/s@1823W in standard with 89F ambient.

Hey Philipma...I say this because of the above post from Blokforge...so wanted to ask the miners if they can confirm the 37TH/s@2098W.

We will be shipping the 1st batch monday.  We need to upgrade the firmware on all units this weekend prior to shipment due to DHCP lease rule code issue on some units.  You should all receive tracking monday.

And this is why we do not dropship to customers, its our responsibility the units are functioning as expected prior to shipment if purchased from us.

Thanks for your patience.

So if the shipment gets to Blokforge first and then it is sent to the miners after they upgrade the software how does the tarriff come into play?

[minefarmbuy]

If it's the US already your fine. Though I recall talks of Blokforge looking at/for fulfillment services from the "Ruling" discussion. Best if they reply or contact them directly.

Yeah, I am hoping they will reply here on the post.

Yes, these are running 36-37 TH/s @2098 give or take a bit depending on ambient temp.

Correct, we paid tariff already on the miners in stock, pre-order pricing does not include tariff, willl be added at checkout if in the united states.

PM me your pool info, we can point one there a few hours.  blocksfactory is tricky as you need to really need to get the perfect difficulty level figured out and add to worker name, pool doesnt really like vardiff that much for some reason. 

[NotFuzzyWarm]

Got my 1st of 3 A10's today and looks to be in fine shape.
About using the loose PSU: You should include a picture of how the heavy-gauge + and - power cables connect to the PSU and miner as there are NO markings on the miner saying what-goes-where. Yes I have pic of it (from Blokforge) handy but I'm sure many folks may not have that.



edit: CRAP! Missing a part - the little circuit board seen in the pic on top of the PSU. The board connects the ribbon and 2 other cables together and I'm dead in the water without it...  
Ticket started with Blokforge

Really hoping that the 2 other miners arriving tomorrow have the board...
edit edit: Nick @ Blokforge is overnighting me a replacement. Love those folks and their excellent customer service!

[Pyrojason]

Sounds like they're really on the ball there - a shame it was missing but great that they've been so easy to work with.

How many wires is it? Could you have wired it by hand in an emergency or is it one of those maze-like-so-many-tiny-wires-of-doom connections?

[philipma1957]

wait for a link

look at about 3:01 time  he is missing that black connector = DOA until you get one.

I have the older firmware.

[NotFuzzyWarm]

Yep. That's it.

Looking at your video I see that there is an insulator strip under the power lug connections to the miner. VERY good idea and is lacking on the miner I got. Yes at least there is an insulating nylon grommet around the hole where the miner power connects BUT nonetheless there is very little gap between the power lugs and the miner casing.

Along with marking the polarity I immediately applied a couple layers of electrical tape under the edge of the grommets and covering where the power lugs might come in contact with the case.

[HagssFIN]

The polarity markings are well hidden under the cover in the hash board.

[NotFuzzyWarm]

1st. The needed missing adapter plugboard came in as promised

2nd. Arrgggg.... The miner is not showing up on my router  
The LAN port light on my switch for the connection to the miner comes on for about a second then goes out for about 3 sec, loops forever like that. Looking at the router connections I sometimes very briefly see and new name & IP pop up but it goes away before I can read it. I assume that is the miner trying to connect?

 Never mind - after about 10 min it found it and the connection looks stable.

[philipma1957]

I had a lot of lan appearing then not appearing issues then appearing.  but my 2 have been stable for the last 15 days
