1) General information, other items needed
(top)
AvalonMiner 851 is a Bitcoin (SHA-256) ASIC miner using 16nm ASIC chip technology.
It is manufactured by Canaan Creative (headquarters in Beijing, China).
This miner is the third 8th generation AvalonMiner model,
and it uses a 16nm Bitcoin ASIC chip called A3210M.

The chip performance and power efficiency is quite close to the A3210HP chip used in the AvalonMiner 841 model.

AvalonMiner 851 does not have a built-in controller included and you need a separate controller unit,
like AvalonMiner Controller or any of the Raspberry Pi single-board computer models to run it.
This feature makes it possible to connect up to max. 20 AvalonMiners to be controlled by the controller unit.
Five miners per one AUC3 converter and four AUC3 converters per one controller unit.
This saves some money in network infrastructure cost especially if you have a large mining operation.

AvalonMiner 851 weights 4.7 kg and outer dimensions are 370mm x 150mm x 136mm.
The nominal hashrate is 14.5 Th/s (-5% – +10%) with a nominal power consumption of 1450 W (+0% – +20%).

This is a review and also a setup instructions guide for the AvalonMiner 851.

There is also a separate troubleshooting guide for AvalonMiner 7 and 8 series.

    every connector with a dedicated cable and at least 18AWG wire gauge. The power capacity is recommended to be at least 1600 W.
    Sorcerer Power Supply Unit is the official 1600 W custom power supply unit for AvalonMiners.
  • C13 power cord suitable to your country's electrical socket. Use only good quality, large wire gauge power cords.
  • AvalonMiner Controller or Raspberry Pi single-board computer.
  • 5 VDC 2.4 A USB wall wart for the controller unit.
  • USB Type-A -> Micro USB cable between the controller unit and the 5 VDC 2.4 A USB wall wart.
  • Ethernet cable to go from the controller unit to your router/switch device.
  • Computer to set initial pool and configuration settings.

2) Unpacking
(top)
This AvalonMiner 851 unit was received as a sample unit and I decided to do a review for this new 8 series model.

The packaging is done in the same way as with the previous AvalonMiner 8 series miners.
So these notes and images are quite the same as in the AvalonMiner 841 review.

There are two pieces of foam in both ends of the miner supporting and protecting it,
and also one piece of foam in the middle section.
The cardboard box is just the right size for this packing setup and there is no extra space.
This is important as we don't want the miner to move inside the cardboard box during the shipping.

The large courier companies lare able to do the delivery pretty fast internationally even with the standard service
and it took DHL only 5 working days to deliver shipment from China to Finland.
even though the straight line distance between these countries is roughly 6000 kilometers.

After unpacking and unwrapping the miner was ready to be setup and tested.

When you buy a A851 unit, you get the miner and one AUC3 cable.

It is important to notice that you also need the AUC3 converter, a controller unit and of course a power supply unit.
With previous AvalonMiner series models there used to be one AUC3 and AUC3 converter in the same cardboard box with the miner,
but now you need to buy AUC3 converters separately or buy the AvalonMiner Controller kit.

With AvalonMiner Controller kit you get this following list of items:

AvalonMiner Controller product list.

As mentioned earlier, if you want to use your own Raspberry Pi single-board computer as the controller unit,
it is also possible to buy AUC3 Converter dongles separately from both Canaan and their official distributors.

3) Overview (top)
This following chapter focuses on having a close look at the miner
and the controller gear that I used with the miner.

4) Controller unit setup (top)
When it comes to the controller unit, you have two options:

1. You can use the AvalonMiner Controller.
Using it is very straight forward, because it is ready assembled
and the OpenWrt based firmware is already installed on the Micro SD card.

2. You can build one yourself by using a Raspberry Pi single-board computer and other supplies.
So in this next part you can see how to build a controller by yourself,
using a Raspberry Pi 3 single-board computer and some other supplies needed.

It is fairly easy to source these parts needed and you can use a local electronics store to find these supplies.

Here is an example for the shopping list:
  • Raspberry Pi 3 single-board computer
  • Case for the Raspberry Pi 3
  • 8GB Micro SD card
  • 5 VDC 2.4 A USB wall wart
  • USB Type-A -> Micro USB cable

It is strongly adviced to use a server grade power supply with at least 1400W power capacity.

Click for a higher resolution image.

7.
Plug in the 5 VDC wall wart to power on the controller unit.

8.
Connect a C13 power cord first to the power supply unit and then to the wall socket.
Make sure that the power switch in the power supply unit is turned on.

How to do a setup for twenty miners and one controller unit:
If your setup is going to have more than one miner, you can daisy chain max. five miners per one AUC3 converter
and you can connect max. four AUC3 converters to one controller unit.

The setup principles are pretty easy to understand by looking at these following two diagrams:

6) Configuration (top)
Controller configuration instructions:
1.
Connect the power to the controller, and make sure that the controller and computer are connected to the same local area network.
The other option is that you can also connect the controller directly to the computer with a network cable.

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

Click for a higher resolution image.

4.
There is initially no password, so you can enter to the Dashboard after you click Login.


5.
You can click Configuration to configure your miners and see your pool information.
For example, you can set up three pools and corresponding 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 you can change your computer back to the automatic IP address acquisition.

8.
If the controller is properly connected to the Internet, you can access different sections
in the miner web configuration page, for example the Cgminer configuration page and the miner status page.
As long as a miner is correctly connected via AvalonMiner USB Converter to this controller unit,
you will see them on the overview page and see relevant information on these devices.


7) Performance test (top)
After all the setup and configuration is ready, it is time to test the miner.
Mining was started using the default settings.

The average hash rate after close to four days of running time was 14.55 Th/s.

The advertised hash rate for the AvalonMiner 851 is 14.5 Th/s,
which is the minimum hash rate for every sold unit.
They say that the actual hash rate is always above the nominal value,
and the unit tested here was able to perform 0.05 Th/s better than the advertised value.
So I'd say it performed as advertised.

The power supply unit used in this test was Bitmain APW3++ 1600 W power supply.

The power measurements were done with Perel E305EM6-G energy meter.
Click here for Perel E305EM6-G technical specs data sheet.

The miner was set with default settings.
Hash board frequency is controlled automatically to make each hash board perform best as possible.
The default value for Voltage Offset setting is 0.

Power measurement. Click for a higher resolution image. Picture taken by HagssFIN.

The result for the power consumption (at wall) was 1669 W,
when the average hash rate was 14.55 Th/s.

With these results the power effiency at wall can be calculated.

1669 / 14550 = 0.1147 J  per  Gh/s.

8] Conclusion (top)
Once again I would like to give big thanks to Canaan,
especially to Steven and Lily.
They really do solid work in the mining hardware field.

The 851 is leading the way for bigger hash rate & power load AvalonMiners.
But while the design is improved further a little, the down side with this particular model
is that the power efficiency is not as good as it was with the 841.

Canaan is already developing and producing the following AvalonMiner series, the 9 series,
and time will tell us what kind of designs that series consists of.

I'm willing to bet on one thing: they will continue to make rock solid quality mining gear compared to some of the competition.

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


9) How to order
(top)
Bulk quantity orders:
If you want to buy bulk quantity of miners, you can buy them directly from the manufacturer Canaan Creative.
