AvalonMiner 741 Review & Installation Guide

Ledger Wallet protects your bitcoins

Some days ago I’ve got my hands on the AvalonMiner 741, the new Bitcoin ASIC by Canaan. The Avalon 741 is an improved version of the Avalon Miner 721. It features higher hashrate and a much better cooling system to allow the 88 chips to function stable.

In this article, I am going to review the miner as well as provide you with a detailed set up guide. I’ve created this tutorial it since I haven’t found a working guide on the Internet and had to figure out some steps on my own. Now it’s all served, ready for you to enjoy!

The Avalon Miner comes in a sturdy metallic box with one fan. The first thing I’ve noticed about the miner is that if you look through the fan grid, you will notice the weird shape of the heatsinks. Apparently, the AvalonMiner 741 features the Airforming Cooling technology that allows it to dissipate heat more efficiently. This is a great feature for a miner that functions 24/7.

What about noise levels? According to Canaan, the miner alone produces between 50 and 60 Db.In my case, I was not able to isolate the miner from other noises when measuring. My sound meter shows an average of 63 Db, however I was also picking the noise from my 1600 W PSU and PC.

Price-wise, the miner is accessible to the average mining enthusiast by being priced $798.00 USD on the official Canaan website. According to some calculations, the miner should be mining around Ƀ 0.05968 per month, which translates into $ 171 USD/mo income, electricity fees included. If we don’t take into account Bitcoin price and difficulty fluctuations, the AvalonMiner 741 has a ROI of around 6 months. This does not include the cost of a new PSU.

What Comes in the Package?

Back to my own experience with this miner. I’ve got it some days ago and have been testing it since then. It is worth mentioning that the miner came well-packed. Just as stated on Canaan’s website, here is what came inside the box:

You do not get a PSU or the AvalonMiner Controller. I recommend you using a 1600 W PSU – this way you avoid throttling. About the controller, I have used a RaspBerry Pi 3 Model B one instead, as described below.

AvalonMiner 741 Installation and Setup

When I first got my AvalonMiner, the first thing I did was to google for a step-by step tutorial on how to set this thing up.

While Google did not fail me and shown me a couple of guides on how to connect the cables to the miner and turn it on, I haven’t found one that would cover all of the needed steps to set up the 741. In fact, it took me a couple of hours to make this thing work. So, without further ado, let me show you the exact steps I’ve followed to make the miner function as intended.

Here are the things I’m using besides the miner and what comes with it in the box:

  • An AvalonMiner Controller or RaspBerry Pi 1/2/3 (I didn’t get an AvalonMiner Controller from Canaan, so I’ve bought a Raspberry Pi 3 Model B which is the same thing. However, this also means that I had to install the OS manually, as shown in this tutorial)
  • A 1600W PSU, in my case I have an Artesyn DS1600SPE-3 1600w 80+ Platinum
  • An Ethernet cable

1 RaspBerry Pi 3 Model B AvalonMiner 741 Firmware installation and setup
(Skip this step if you have the AvalonMiner Controller)

Now let’s make sure that the firmware is properly installed:

  • Connect the internet cable to the controller
  • Connect the power adapter
  • Connect the HDMI to the monitor (not necessary, only if you want some texts J)
  • In your browser, connect to controller using the default IP (if you are not able to connect, edit your IP address as shown here: IMAGE)
  • There is no password set yet, hit login button and you will be redirected to dashboard
2 AvalonMiner 741 Firmware Configuration

  • I am going to use Antpool because it is very user-friendly and easy to set up. You might want to go to and create an account if you don’t have one yet.
  • Once logged in, go to settings and add your Bitcoin address
  • Now, go to Dashboard – > Worker and create one
  • Go back to Avalon dashboard -> Configuration page to set up the pools and worker from Antpool
  • Click on ‘Save & Apply
  • In order to make the Avalon Miner 741 work, you will need to connect it via wireless network. Here’s how you do it:
    1. Click on Advanced Version button (left side menu), then
    2. Go to Network -> WiFi,
    3. click on Scan button,
    4. choose your wireless ID,
    5. click on Join Network button,
    6. enter WPA passphrase (password),
    7. select LAN as firewall-zone.
  • Click on Submit and you will be redirected to the Device Configuration
  • Click on Save & Apply.

After you’ve completed the previous steps, power up your AvalonMiner 741 and connect it with the Raspberry Pi 3 Model B. It should start mining now.

You can check the hashrate reports on the Avalon Dashboard or pool dashboard:

If you are going to use Antpool you can install their app on your smartphone and check the reports from there:

    I get stuck here, as your image link is a picture of raspberry???

    “In your browser, connect to controller using the default IP (if you are not able to connect, edit your IP address as shown here: IMAGE)”

    • Once you connect Ethernet cable to raspbery, from your pc/laptop type that ip in chrome or Mozilla, Avalon interface will popup. If the page doesn’t load you will have to modify your pc/laptop ip like in that image.

      • James Floyd Mills

        I am uncertain by what image is linked to your post. Can you clarify what the IP setting should look like? Thanks

        • you are not able to see the image?

          • Jeff Trudeaux

            Having the same problem and no image isn’t the right one.

  • matthew jessup

    I’m unable to get my avlalon 741 working I have everything wired up correctly and put in my pool info (slush pool) here’s a video of it all plugged in and I attached two photos of my settings

    • matthew jessup

      by the way the light on the back of the miner is currently yellow and I’ve tried changing the cables with other ones multiple times

      • matthew jessup

        one more thing I see you said you need wifi but I’m plugged in through ethernet

    • Go to advanced tab and then to wifi settings, connect the controller via wifi network. have you tried that ?

      • matthew jessup

        I have tried the wifi but not difference I think the controller is not connecting to the miner correctly

        • have you also rebooted after Wi-Fi setup ?

          • matthew jessup

            I’ve done everything can you email me at I see you have a paid service I can setup a teamviewer for you to be able to access the miners settings

          • just emailed you, thanks!

    • People just ignore the contact page 😀

  • Logan J. Harris

    I have followed your guide exactly and I cant get it to recognize my miner, it acts as if it cant connect directly to it.

    • I’m sure you missed something.. have you changed your ip addresses ?

  • Lance

    Error 5 – access denied when I try to write on the SD card… :C Help!?

  • hoste

    Hi, awesome tutorial!
    I have a question about the controller (rasp pi 2B, i followed the steps to create it and to connect it to the wifi. it connects to the wifi and receives an ip address and i’m able to connect on this ip. however when i disconnect the ethernet cable i’m not able to access the controller on the wifi anymore. so my question, is this normal behaviour? if yes why do we even connect to the wifi?
    I’m posting it here since i might not be the only one with this question.

    Thanks again for the tutorial

    • Hi, yest that’s normal, strange that it will mine only when ehternet cable is pluged in and connected to wifi. at least for me this was the only way to make it work!

  • Hey Ciprian! Great informative read. I got most of the way through but I’m having some difficulty with accessing the Avalon dashboard, probably due to IP issues. I shot you a support inquiry. Are you available to answer any of those questions here or through support. Happy to toss some BTC your way for the help! @@ciprianpt:disqus

    • Hey Ryan, yes of course, you can email me! thank you! 🙂

      • Sounds good, I sent in a contact form / support inquiry, but happy to email. May be easier. What’s your email? Or you can email me at

        • Hey @ciprianpt:disqus hate to be a total pest. Never received an email from you and I’m trying to get things squared away pretty quickly. Every passing day = increasing blockchain difficulty lol. Could you shoot me something over to Happy to tip you in BTC or LTC 🙂
