Topic: Avalon A7 announced - page 89. (Read 147678 times)
A721 & A741 are rock solid when it comes to the current generation of ASIC hardware.
If I would be buying new hardware, at the moment I would keep my eyes open for the possible release of AvalonMiner 761 (see discussion above).

I'm looking to make a large order of Miners soon. Seems like everyone has been having luck with their A741's? I don't hear much complaining going on!
Anyone have any recent shipping experience? Just curious what to expect for timing.
Cheers

based on that info, it looks like Canaan has new hashing boards, each with 26 x A3212 16 nm chips on them, so 104 A3212 chips total.
Here's a crappy attempt to guess the 761 hash rate and power use. This guesstimate is based on 741 numbers.
https://canaan.io/product/avalonminer-741/
Hashing:
741: 7,300 GH/88 chips = 82.96 GH/chip
761: 82.96 GH/chip * 104 chips = 8,627 GH
Power Use (low end):
741: 1,150 W/88 chips = 13.07 W/chip
761: 13.07 W/chip * 104 chips = 1,360 W
Power Use (high end +15%):
741: 1,322 W/88 chips = 15.03 W/chip
761: 15.03 W/chip * 104 chips = 1,563 W
Is it true that with auto-adjust enabled on the Avalon741 the hash rate is higher if conditions allowed? If that is accurate, and the Avalon761 has/uses the same feature, then the hash rate may be higher, if conditions permit.

I just noticed that we can probably expect a new AvalonMiner model, AvalonMiner 761 sooner or later.
There is already code for it in Canaan's cgminer github https://github.com/Canaan-Creative/cgminer/blob/master/driver-avalon7.c

For those that have updated their 741's to 7411703-a6ef750 MM Firmware, how many resets are your miners doing in a day? I have already had 4 and it has not been 24 hours yet. I have updated the controller firmware as well to 20170310. I did add --avalon7-nonce-mask 26 to more options after the first two resets so it seems to ramp up quickly compared to the initial restarts.
Another request partner with Giga Watt for miner hosting. I'm sending them your miners to host but I had to contact them and set it up, it would be great if it was listed on their website and I could just order it direct through them with hosting.
Heh, I contacted Giga-Watt shortly after the start of the WTT ICO and asked them if they were considering Avalon miners instead of/in addition to the Bitmain models. They responded within 24 hours and said that they were considering it, but needed to evaluate the miners.

Avalon please make a miner similar to the Bitmain R4 for home miners. I much more so prefer your miners to Bitmain but during winter months it'd be great to have miners at home for heat.

How loud is the 741 compared to the S3?
I retired my S3s last year and got out of mining for a while. Now I am considering investing some of my BTC in a new mining rig. I'm in a 2 bedroom apartment with electricity included and I have a 20 amp circuit I can put a miner or two on it. Not going to quit my day job, but my little pile of BTC from my last effort looks pretty darn good now.
TIA
It's louder but not horribly louder. I'd say start with one and if the noise doesn't bother you get a second one. You could always get hosting for it if it's too loud for you.

With -2 voltage offset and a cold environment you can get it quiet.
That's before replacing the fan, compared to an S3 stock.

When warmer weather arrived I had to drop my 741's to use -2 for the voltage setting for the same reason, kept throttling up and down trying to keep cool. Using -2 now are quite happy and actually just a minor hit to speed. The 3x 721's so far are perfectly happy at default voltage setting.
re: dead s7/s9 boards, you might want to look at where the miners are running... At one time I was running 24 s7's and think only lost 3 boards in total. Most are now retired and replaced with 16 s9's from batch-1 on up and 4 t9's (so far). Only recently had my 3rd bad s9 board, currently at Bitmain Warranty in CO for paid repair - is from a batch-13. Ambient will hit up to 90F but is a clean area with no dirt/dust. Definitely have had several fans die of old-age as well but that is to be expected from any miner.

Edit: They shipped it, tracking number just wasn't correct.
Anyone ordered from them? I can't seem to get a hold of them for over a week for orders.
Thanks!
That worked great, it dropped the hash down to normal speeds, but the temps were low enough to keep the fans under 100% easy.
Right now I've got a paid order with them I'm waiting a few days on an update for, and support hasn't replied back in a week.
They use to be so fast at shipping and replying, something must be going on right now.

Anyone having issues ordering manually?
I get Bad Gateway when I try to checkout.
Got a ticket open for it but haven't heard back in a day.
I have another ticket asking about the voltage offset setting, as I don't want to edit it without them letting me know it's okay, but it's been almost a week on that one.
Having 2 units that are overheating every few minutes in 29C ambient.
All the others running perfect and above spec, sometimes hitting over 8TH.
0 failed chips so far that I know of.
To compare I only have 2 S9s left with all working boards, both the later batches which is unique; that's pitiful from Antminer. Stacks of bad boards from the S7 as well, mostly the 700Mhz ones. Early batches never had an issue and still running 5TH, but they were a premium and a gamble back then.

Edit - eye candy of I think my 1st portable mp3 player...
Took the pic a few days ago, still works and still love the USB-stick setup of it. My current 'lil Sansa with it's 32GB sd card may be smaller/lighter but still gotta love this. Good design there.
Nice! Unfortunately, my last Creative Labs MP3 player was stolen. UGHEdit - eye candy of I think my 1st portable mp3 player...

I loved that design. In fact it gave rise to a project called Lego. The idea was simple. Different bricks snap together lego style.
Alas it never shipped.
I am not sure that Canaan meant that they would get down to the 7nm node in 2018. If you read the language carefully, it sounds like they only meant that there will not be any further progress until AFTER the big players like TSMC hit 7/10nm in 2018. I know that I am taking a bit of liberty in my translation, but it is in line with current road maps.
Canaan Creative sets new price 714USD for the A741 and talks about moving production to 7nm in 2018 .
Interesting.. They are the first miner manufacturer to talk about future smaller node process. No schedule news from Bitmain, yet.

Nice pricing they've got there, I'm interested to see if they're actually going to hit that date they mention in 2018. We're talking about feature sizes rivalling Intel and AMD's, which is pretty exciting. Glad to see Avalon under new management is much more competent than before, keeping the beast Bitmain under control.Interesting..

HONG KONG, May 21, 2017 – Hong Kong based Canaan.io announced a dramatic move in prices on it’s Avalon series of miners.
As the price of cryptocurrencies continue to escalate, our drop in pricing makes mining an attractive option again for the individual miner.
Steven Mosher, Head of Global sales, said “Going forward we expect the companies that build mining
equipment to make more regular and predictable increases in machine capability.
The next big jump in capability won’t happen until production moves to 7nm in 2018,
so it makes sense to move the prices down and open up more opportunity for individual miners.”
SMART-SPEED.
The AvalonMiner 741 delivers a hash rate that does not fall below 7.3 TH/s and can achieve rates above 8 TH/s.
This performance is the result of a unique chip design.
Unlike other ASICs that are speed sorted, the A3212, is designed to “find” its optimum speed
by dynamically increasing the internal clocks and simultaneously verifying the output.
Min Chen, Canaan Chief Technology Officer explains:
“With SMART SPEED every chip is pushed to its optimum frequency based on the real time conditions.
We dynamically monitor the hashing functions to ensure that only valid hashes are output while driving
every internal core to the maximum achievable frequency for that core”
Pricing And Availability:
The AvalonMiner 741 is now available priced at $714 on canaan.io.
