Yeah, I can't justify buying one right now.
It would never come close to ROI with my power cost.

Now maybe if I have it hosted it somewhere...

I do not mind that it is a .15 watt miner.

With the solar array I simply need reliable miners.  The s9 just does not cut it for reliability .

The 721 gets about 171% of the hashing power of the A6 for about 83% of the power consumption.  While those numbers aren't the most impressive, I'll take Avalon quality every day of the week over Bitmain.

Pros:
+ open source software.  It's all on GitHub.
+ uses standard cgminer.  None of the Bitmain BS.
+ can chain multiple units on a single controller.
+ customer service and support.
+ uses standard PSUs. No need for anything special or additional PCI-e cables.

Cons:
- expensive. $888 is tough to swallow for a 6TH miner
- ratio of hash to power consumption. Expected more from Avalon's next-gen 16nm chips.

Nothing here about this yet? Is everyone sleeping?

https://canaan.io/2016/11/07/the-avalonminer-721-is-roq-solid/

$888 USD - 6 TH/s - 900 watts

screen shot.

it is costly  888 plus shipping
it is a power hog 900 watts for 6 th


so to be worth the price it needs to work and work and not fail

...
2: The controller shuts off at 45c yet its inside a metal shell sitting on top of a giant heatsink radiating 75c heat. This means over about 30c-32c ambient the controller shuts down due to heat issues.
...


update the firmware, than it shut down only if the board temps gets to high, not on the "intake air".
So you can cool them with warm/hot air, but of course need more airflow.

There is very interesting news about the Avalon 7  Smiley

Here is quote wrote by cgminer developer Kano in his pool thread:
Well those damn S9's are back and there goes the luck!!!!!!!!!!


Hi Kano - can you run the latest S9/BDR stats, if any... just to be sure... I have a strange feeling about bmminer 1.0. All of Juvia is still bmminer 1.0 and I have not upgraded to bmminer 2.0. I hate to think that there is something rotten in v1 firmware against Kano pool. Thanks
The stats are only getting better, not worse.
Also the 2.0 has now found a block with a BDR less than 1.0


However, for more interesting news ... there's been an A7 pull request on cgminer Cheesy
https://github.com/ckolivas/cgminer/pull/701


That is no way is reference to Avalon or their new hardware.
Did you even look at the pull request?  It's clearly cgminer updates from Canaan, and it clearly describes changes for the Avalon 7.

I'd say it is a very clear reference to Avalon and their new hardware.
That part is true but the s9 parts aren't.

I quoted Kano's whole message and the important part is marked in bold.

Gotcha, just didn't want there to be a miscommunication.

Unless you're a conspiracy theory nut and believe that Bitmain has purposefully sabotaged the S9 to not work with any ckpool instance Tongue.

Wait...

I figured it out!  No wonder they don't work on kano's pool!!!  Roll Eyes

I'm positive that they will at least reveal the miner in 2016

Lets hope the A7 fixes the giant flaws with the A6...namely the massive cooling problems the A6 has
I've got 20 A6 and haven't experienced anything remotely like what you are describing.
Never had a problem with my A6 in the basement and overheating issues.

and The avalon6-se is special in the way that it makes more room for their newest miners.

1: Heat sink design. It is one massive piece of metal and retains as much heat as it releases.

2: The controller shuts off at 45c yet its inside a metal shell sitting on top of a giant heatsink radiating 75c heat. This means over about 30c-32c ambient the controller shuts down due to heat issues.

3: They radiate some kind of infared heat that means when you put a bunch of them close together they tend to overheat each other even if the ambient temperature is not that high.


Also please take into account that I am talking about how they act in an industrial environment, not some random home user that thinks running 10 or 20 is a large enough sample size to call them great. The scale of the operation and the amount of heat generated will cause these flaws to show up whereas someone just running a few at home will never see the issue. I have had these machines tested and they shut down well before their rated max operating temperature. In the lab environment at 85f they have serious problems running versus the s7 that was able to run in 110f ambient without shutting down in the same test.environment.



number 2 is an issue once you get a lot in stacks.

thus a long single row  with spacing between units works which is not good for 100 or more.

Some were able to run them on a concrete slab with a short shelf setup. but that is not ideal for 100 no less 1000 units.  the s7 were pretty sturdy use them up to 105f with no issues stacking them.

I've got 20 A6 and haven't experienced anything remotely like what you are describing.

maybe he was using a hot attic space to mine with them.

 when the room got near 100f it had issues, but that is the rooms fault not the A6

I agree. The ventilation in the room is what really matters. If you have a very hot air in the room you can't cool your miners properly even if their cooling fans are operating at their best.

Is the Avalon 6 SE any different form the Avalon 6?
Where do you see the Avalon 6 SE ?

I think what makes this edition "Special" is it's price. Beyond that, the specs look virtually unchanged from the Non-special versions that were produced 6 months ago.

This isn't a complaint, it just a recognition that this is more "Marketing" than "Technical" in nature.
