Avalon 7

[jonnybravo0311]

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.

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 .

[Sierra8561]

I really had my hopes up.

Agreed, the quality of the Canaan products is vastly higher than Bitmain.

Yeah, your solar really helps. I have pretty much gotten to the point where I can no longer mine at home.
My power cost is nearly $0.13/KWh. I have sold almost all of my miners.
The only thing I have running are some S3's in the house and occasionally an S4 in my garage.

The only reason I can really justify running them is for the heat.

Yeah I am at 12 cents in my house. Heat is worth 3 cents so 9 cent net from now to May 2017.

The solar array is better then that for me. So I will buy these from Canaan .

I really had my hopes up.

Me too. But over 300 days for ROI with free power is a non-starter for me.

I don't want more S9's because of their bad quality. But the price of Canaan quality is too high. I'm stuck...

I guess I should be happy with the hash rate that I have. Maybe if the 721 comes down in price, or if Bitmain improves their quality now that competition is really on the horizon, I can look to expand.

[HagssFIN]

I have mixed feelings. First I'm happy but then second I'm also a little sad because of the lower efficiency, ROI time and price (compared to previous two things).  --> my face right now

Phil, you going to get a group buy going on theses?  Too early to ask??

[flameruk]

So I don't confess to have ever seen an Avalon, but reading what you guys say about quality I guess these are the real deal.
Looking at the watt per hash rate, it seems lower than what Bitmain can achieve with the S9's.

Maybe, just maybe, the S9 hashes at a rate where the miner destroys itself over time but the new Avalon thunders on forever as the chips don't thrash their own bollox off, hence the lower efficiency.

I guess time will tell.
Just a though folk ...........

It's the heat that burns down things.
You're theory doesn't make sense.
Better efficiency is not bad at all in the temp sense.

[philipma1957]

If the need is there I will.

I.E. if they have a MOQ of 10 I will do a group buy.

Yes exactly!
The S9 runs hard to get the high hash rate, high heat and high breakdowns.

Maybe the new Avalon runs smoothly, less heat and less breakdowns.

Something along those lines..........

Heat part is right but better efficiency has nothing to do with those kind of problems.
That was my point.

edit:
By the way, I'm surprised that I did guess some specs right in this message September 20

....  so a total of 72x A3212 chips.
So 70Gh/s /chip would make it a 5.04Th/s miner
80Gh/s /chip would make it a 5.76Th/s miner
90Gh/s /chip would make it a 6.48Th/s miner
100Gh/s /chip would make it a 7.2Th/s miner.
I'm guessing it's a 6-7 Th/s miner.

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

Look at my last post on the kano thread.

[valkir]

Im waiting to see if there will be a MOQ. I will probably do a Canadian Group Buy

Let me know via PM if you want 1. I will create a thread soon. 

Will use it to heat my place!

Yeah, I saw that. If I had free power I would buy several, especially since I have to heat my house about 8 months of the year.

Sending them to be hosted might be an option, but it is one more factor in the upfront cost. After it gets there and starts working you can save the coin you make to make the payments, but they all give a discount if you pay ahead so...

[allinvain]

I hope there is no MOQ. I may do a group buy if anyone is interested in having them hosted with me at CryptoBoreas (Labrador). But if not and there is someone trustworthy that will do a group buy, I'd be interested.

If you figure in the costs to have boards repaired on the S9, the Avalon is really not a bad deal

I just paid $200 to fix an S9 board even though the unit is still under warranty. I already started selling off my S9's and will definitely be buying the new Avalon. Allinvain, Count me in on a group buy/hosting

Same reason I won't point my miners to a pool such as Viabtc, it's the principle

yeah I had six s9s,  five as a partner in the solar array.  And one for buysolar alone in the solar array.

All told 18 boards four replaced spare parts purchased 300.
Rma shipping .and repairs 300

That is six hundred. And. Down time say 300. So 900 extra from June to Nov.

My cost for six units was 10k + the 900 so say 11000 . Say 6k back from selling so 5k down.

Earned 2.75 btc so that is 2k so I am down 3k .  With 2 machines left. 

Would be much better off if nothing had broken.

I've been trying to add Sonia Xu on skype but lol there are so many people with that name. Does anyone happen to know which is the correct person? Where is her location? I want to talk to her about organizing a possible group buy.
