1) General information, other items needed

AvalonMiner 741 is a Bitcoin (SHA-256) ASIC miner using 16nm ASIC chip technology, manufactured by Canaan Creative (headquarters in Beijing, China).

AvalonMiner 741 does not have a built-in controller and you need a separate controller, AvalonMiner Controller or any of the Raspberry Pi versions to run it. A good feature is that several AvalonMiners can by chained to be controlled by one Raspberry Pi.
The nominal hashrate is between 7.3 to 8.0 Th/s with a nominal power consumption of 1150 Watts.

These products are included with the miner:
AvalonMiner 741    1 piece
AvalonMiner USB Converter 3 (AUC3)    1 piece
Micro USB Cable    1 piece
AUC3 I2C 5PIN Cable    1 piece

AvalonMiner 741 weights 4.3 kg and outer dimensions are 320mm (L) x 136mm (W) x 150mm (H).

This is a review for both the hardware and for the buying experience from a local official Canaan distributor, Cryptouniverse.

Technical specifications:
Code:
AvalonMiner 741

Hash rate: 7.3 (min.) - 8.0 (max.)  Th/s
Power consumption: 1150W, +0% ~ +15% (with 93% PSU efficiency @ 25 C)
Power efficiency: 0.16 J / Gh/s  (at the wall)
DC voltage input: 12 VDC (max. 12.53 V)
ASIC chip type: A3212 (16nm SHA-256 ASIC chip)
ASIC chip quantity per unit (miner): 88 chips
Number of hash boards per unit: 2 hash boards
Cooling: 1x 120mm x 38mm 12VDC 2.7A fan; manufacturer & model: Cooler Master A12038-60BB-4RP-F1 (mounted in rear for a pull configuration).
Weight: 4.3 kg
Dimensions: 320mm (L) x 136mm (W) x 150mm (H)

Other items needed:
-A server grade power supply with at least 6x PCI-E 6-pin connectors, everyone with a dedicated cable, preferably at least 16AWG wires.
I used a 1600W power supply called Sorcerer Power Supply Unit to power my miner.
This is a custom power supply manufactured by Canaan Creative.
-C13 power cord suitable to your country's electrical socket
-AvalonMiner Controller or Raspberry Pi
-Wall wart for the raspberry pi.
-Micro USB cable between raspberry pi and the wall wart.
-Ethernet cable to go to your router/switch
-Computer to set initial pool and configuration settings.


2) Unpacking
So, as Canaan Creative has changed their strategy by selling small quantity orders via their official distributors,
I bought this kit from their distributor called Cryptouniverse.
Cryptouniverse is located in Austria and their main area is the EU area,
but they are also selling hardware to other locations.

Cryptouniverse
: www.cryptouniverse.at

I bought a kit, which also included the power supply and the controller, which you would normally have to buy separately.
BITCOIN Mining Set Avalon 741: https://www.cryptouniverse.at/shop/bitcoin-mining-set-avalon-741/
Quote from: Cryptouniverse
This product contains:

Avalonminer 741    1 piece
Avalonminer USB Converter 3 (AUC3)    1 piece
Micro USB Cable    1 piece
AUC3 I2C 5PIN Cable    1 piece
Controller   1 piece
Sorcerer Power Supply   1 piece

This product DOES NOT contain (You will need it to power the SET):

Mico USB Cable + 5V 2A Adapter    1 piece
Powercable for the Powersupply    1 piece

As I live in Finland, I'm really happy to see an European distributor selling Canaan hardware.
It makes the buying process so much easier, no need to go through the process with customs.

The delivery time from Austria to here in Finland was quick enough, seven days.
It was sent from Austria in December 5.
In December 12 it arrived via GLS (GLS Standard service) to their local delivery partner, Finnish postal service Posti and I was able to pick it up at the post office.

All the good were packed in a big cardboard box and there was lots of foam for support and protection.
Packaging for the miner was good as it usually is with Canaan products.
The power supply was also packed nicely in foam.

And of course there is a basic setup instructions paper included.
More specific setup instructions can be found online at Canaan website www.canaan.io

Here are some pictures.

3) The miner
Here are some pictures about the AvalonMiner 741, AvalonMiner Controller (Raspberry Pi 3 inside a metal case) and the Sorcerer Power Supply Unit.
Click the picture to show a bigger picture. Pictures taken by HagssFIN.







                 

The Sorcerer Power Supply Unit is something that I have not bought and tried before.
So it was nice to buy one in this occasion.

Only minus side that I can find about the power supply is that they have used CapXon capacitors in it.
Some other brand, better quality capacitors would be a nice change.
When I look at the product page for the power supply at www.canaan.io, I can see that there are Rubycon capacitors installed.
So I suggest they ditch those CapXon capacitors and continue with using only Rubycon capacitors.
Rubycon capacitors have better quality.

Otherwise the power supply looks very nice and well made.

I bought a C13 to Type F (schuko) power cord for the power supply.

I also had to buy a wall wart for the AvalonMiner Controller (Raspberry Pi 3) and one Micro USB Cable.

I also did a quick disassembly for the miner, took some pictures and then assembled it back together to continue the mining.
The disassembly and assembly was quite easy, only one screw driver (with Phillips screw head tip) was only needed.
I took some close up pictures of the daughterboard and hash boards.

I really like the robust cooling solution that Canaan has come up with the latest AvalonMiners.
Those are some big ass sized heat sinks with fine fins. Very effective.
They call their solution Airforming Cooling Technology.

4) Install
The installation was straight forward as it has been for several AvalonMiner generations now.
Connect the AUC3 (AvalonMiner USB Converter) to the AvalonMiner with a 5-pin cable.
Connect the AUC3 other end to the controller (Raspberry Pi) with a micro usb cable.
Connect the Ethernet cable to your controller (Raspberry Pi) and the other end to the router or switch device.
Connect the wall wart to the controller (Raspberry Pi).

And then you need a high power server grade power supply. Install all six pieces PCI-E 6-pin power cables to the power headers found at the front side of the miner.
Connect the power cord to the power supply and to the electrical wall outlet.

Canaan Creative has also made a tutorial video for visual instructions.
Link: https://www.youtube.com/watch?v=Iz9ujCdRXn8

5) Configuration
It is easy to setup the controller by following this guide step by step:
https://canaan.io/question/how-do-i-connect-an-avalonminer-721-and-avalonminer-controller-including-raspberry-pi-1-2-and-3/
You can skip the first part and go to the Configuration Controller part of the guide.

Code:
1. Connect the power to the controller, and make sure the controller and computer is configured to be connected to the same network. (Also can use the controller and the computer network cable connected directly)

2. The default IP for the controller is 192.168.0.100. The IP address of the computer needs to be adjusted access to the controller.)

3. Use your browser to access “192.168.0.100”, and you will see the following login screen.

4. There is initially no password, so you can enter after click Login Overview screen.)

5. You can click Configuration to configure your ore miners and see your pool information. For example, you can set up three pools and corresponding ore miners with the default execution priority pool1> pool2> pool3.)

6. If you need to change the network settings for the controller, click on Network to configure, click Save & Apply, and then power down your unit, and manually restart the controller.)

7. After the configuration, Change your computer back to the automatic acquisition of IP.

8. If the controller is properly connected to the Internet, you will see mining pools and miners setup such as AvalonMiner 741 and 721. As long as they are correctly connected via AvalonMiner USB Converter to this controller, you will see them on the overview page and see relevant information on these devices.)

6) Testing
After all the configurations were made, it was time to test the miner.
I started mining with default settings.
The average hash rate was after two hours was close to 8 Th/s.

So this specific unit is definitely in the best perfomance area, when you look at the nominal expected performance mentioned in technical specifications.


Status page. Click for a bigger version.

The firmware Canaan uses with the AvalonMiner is based on the OpenWrt and it is really clear and easy to use in my opinion.
Canaan provides very frequently updates for the firmware and the cgminer software is always up-to-date.
When it comes to the software, they have an open-source policy and they respect it.
This is not the case with some competitors.

7) Power consumption measurement
The power measurement was done with Perel E305EM6-G energy meter.
Technical specs data sheet (.pdf document): https://www.perel.eu/downloads/22/e305em6e305em6ggbnlfresdptpl.pdf

Power measurement. Click for a bigger version. Picture taken by HagssFIN.

Stable result for the power consumption (at wall) was 1382 W,
when the hash rate was close to 8 Th/s.

8] Conclusion
AvalonMiner 741 might be close to EOL (end of life) as a new generation AvalonMiner model is coming available soon, but I think that it is still profitable
for some time and it is definitely one of the most robust Bitcoin mining hardware available and I wanted give it tribute by doing this review.

I would like to thank Canaan Creative and Cryptouniverse for a nice miner and I was happy to give a review for it here at the forum.
I really appreciate the sturdy design and reliability with the AvalonMiner.

My first experience buying from a official Canaan distributor was really easy and pleasant experience.
I hope to do business again in the future.

If you got any questions, feel free to drop them here in this thread.

If you got questions about ordering, go to your local distributor or Canaan Creative.


9) How to order


If you want to buy 60 units or more, you can buy them directly from the manufacturer Canaan Creative.
https://canaan.io/shop/

If you want to buy less than 60 units, you need to go to your local official Canaan hardware distributor.
You can find the up-to-date official distributor list here: https://canaan.io/official-distributors/

I used an European distributor Cryptouniverse, since I live in Finland.

Great review! I really do like that cooling solution. Looks a lot like one
I have on an old Altec-Lansing power amp. How effective is it on a Hot day
with only the one fan? Anyone know? HagssFinn you do a great job of organizing
the flow of your reviews...Very pleasing on the eyes!

Awesome review brother. 

A question about these Avalons - is the single fan an intake or an exhaust?  Want to have an idea of how to handle ventilation should I pick up a batch.

Exhaust fan. We tested shrouds but this requires removing the stock fan.

Great review! Very helpful and comprehensive.

I've read a few threads about cleaning the 741 and it doesn't seem to be all that hard, but I was curious if you have any extra tips for care/maintenance?

One word: compressed air.

Do not vacuum it, because of the risk for static electricity.

Great, thanks again.

Will blowing some air on intake/outtake have much of an effect or should I just sack up and disassemble entirely for cleaning?

Please remove the fan first, and I would also remove the 'honeycomb' grill too to allow more space for cleaning through the unit with compressed air.

Hi

Does the AvalonMiner 741 allow you to mine any cryptocurreny for example etc or ltc or bitcoin only?

Kind Regards

Rashid

Eth or etc --> no.
Ltc --> no.
Bitcoin --> yes.
Any other SHA-256 algorithm based crypto --> yes.

Went ahead and cleaned mine for the first time since it started running (almost 40 days). Removing 8 screws is not that time consuming and I had it back online before the next block on slush Smiley

thanks again for the review
