Also.. how do you get your hands on an Avalon controller?

An Avalon controller is a raspberry pi Smiley

The Avalon 7 is finally announced:

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

6TH at 900W.  $888.  Sales start 14 November.

Was really hoping for higher efficiency in the new model..  Isn't that 1.5X the power for the same Hashing rate?

Beats the s7, I guess.

Or am I missing something?   Its good to see something new from Avalon.. but I'm disappointed they didn't at least reach the bar.


It's definitely a more expensive piece of hardware than Bitmain's latest.  Dollar per hash and watts per hash are both better with the S9.  However, Bitmain's hardware is flaky.  Bitmain's customer service is painful to deal with.  Bitmain's software is atrocious.

So... the question becomes, "how long will my hardware function without the need for maintenance or repair?".  With the S9, the answer is "not that long".  Hopefully Canaan has built the 721 to the same quality standards as their previous generations.  I've got 20 A6 that are all hashing away.  I think I've rebooted them a few times... and I replaced the fan on one.  That's the extent of my maintenance.

I'm very happy with the quality and the up-front price premium is something I'm willing to pay to have the peace of mind.

It's actually reasonable for cost.  Its the cost of operation that is 1.5X of the s9.. and important part of payback.

I know people have complained of the quality, but I haven't seen an issue, personally.  As far as longevity, I think the history of keeping something for more than 18-24 months.. is unlikely.  An S9 bought today better be sold within a year if you want to get any money out of it.

I've kept my S5s too long.  I'll be lucky to get $100 bucks a piece for them... and I'll fell guilty about it.  Smiley

18-24 months is not the expected lifespan of a miner.  However, when the S9 breaks within 20 days of purchase... or shows up with a dead hashing board, or a dead controller.  Or after 30 days one of the boards dies on you.  Those stories are far too prevalent.  People have spent hundreds of dollars extra to replace parts, and they suffer the down time while their miner is either completely offline or if one of the boards dies, getting half the expected hash rate.

I have an S5.  One of the boards died on it.  It was brand new when I got it (received it from a guy for work I did for him).  It hashed for a while, and it was pretty steadily averaging 1.1TH/s.  My Avalons have suffered no such loss of functionality.

This isn't to say that all S9s are faulty.  It is simply my opinion on the quality of the hardware when comparing the Avalon to the Antminer.

Again, I understand.. I still lament the efficiency.

My s5's have been pretty rock steady.  My consumer Power supplies.. not so much.

Well - look at the physical construction in order:
S1 - bare boards no protective box (and the whole OS was copied from Avalon)
S2 - wow that was a massive failure - sometimes fell apart or were broken during shipping
S3 - finally a physically solid miner
So it took them 3 goes to produce a physically solid and reliable miner

S5 - ... a thin piece of plastic on each side ... effectively no box ... wtf? why did they change that?
I stopped here, I've no idea what the later models are like.

Yeah I never did like the s5

The s-1 looked cool but was a pet+kid trap.

I would say the s-3  was their nicest looking and well made.

I have an S1, a S3, and an S5.  I really liked the S1 because it looked so raw and technical, but the S3 was my most solid miner of the bunch.  The S5 I had to add 3D-printed top, bottom, and intake fan spacer plus hard acrylic side covers to get decent airflow through the thing.  Then I got an A6 and promised never to use Bitmain junk again.

Well, as much as I want to move to a new Avalon product, I think their release is insufficient.

It's been so long since the S9 has come out.  It just doesn't make sense to come out with a 30% less efficient box at this stage of the game.

I think I'm going to take my chances with an S9 or R8.

I consider myself fairly warned.  Thanks guys.

Good luck.  I hope you manage to get a good, stable unit.

If anyone is wondering, I've sold 18 of my 20 A6 units and am waiting to hear back from both Canaan and my hosting provider on acquiring some 721s.  That's why my hash rate is way down.  I'm not pointing it somewhere else Smiley.  Hopefully I'll be back up and running (albeit likely with less hash than I had before) shortly.

In the meantime, let's do a Thanksgiving promo.  Whoever finds a block between now and the end of the day Thursday (23:59:59 EST on 11/24) will receive a 1BTC bonus from me.

Good luck everyone!

So I'm trying to buy some hash from nicehash and it keeps disabling miners from signing on. 

It hints that this might be due to low difficulty of the pool.

Is this something I can set, or is it something the pool itself sets?

Sorry.  I feel like a newbie asking this question..  :/

If you're renting, configure your hash to use port 3334.  It has a much higher starting diff.
